1. Blue Pure Fan Purifying Air Purifier

Blueair Pure Fan Review

Blue Pure Fan Purifying Features And Build Quality

Blue Pure Purifying Fan is a cooler + air cleaner combination that stands out internally and externally. Proudly Swedish-owned. The first thing you be greeted by Blueair Pure Fan Purifying's minimalist exterior. At a small 19.2 inches in width, short 16.2 inches in height, and 14.6 inches in depth, the boxy, low center gravity design makes it impossible to knock over. Blue Pure Fan fits well on the floor but can be placed on a table depending on your preferences. A convenient wood feel handle makes moving around the machine an effortless task. Upfront, the large air inlet pulls dirty air in and passes through the fabric pre-filters before distributing clean air. Unlike a standard fan, the pre-filter helps protect the fan blades from getting covered with dust and hair, which could slow the fan performance.

As for controls, Blueair Pure Fan is dummy-proof and super easy to use with a one-button design. You can rotate to turn on/ off the device or cycle the 3 fan speeds via the big Blueair button. The built-in alert will remind you to change the filter when the time is up (usually around 6 months).

On the whole, Blueair Pure Fan is well-built, using sustainable materials like galvanized steel and recyclable plastic that exceed industry standards. There's a standard 1-year warranty that covers all parts and labor that can be officially extended to 5-years for extra peace of mind.

Blue Pure Fan Filtration, Air Performance, And Noise

One of our favorite features of the Blue Pure Fan air purifier is the patented fan technology that lowers room temperature with a gentle stream of airflow. The purified cool air circulation is distributed across a wide 90-degree angle without the need for oscillation. Through third-party testing, Blue Pure Fan is proven capable of removing 2.839μm of dust and 7.234µm of pollen particles in a 1,008 ft³ room based on AHAM AC-1-2019 standard. Great for all areas, particularly bedroom, living room, office, baby room, and playroom.

Unlike a regular fan that distributes dirty air, the Blue Pure Fan will clean and cool your indoor air at the same time. The onboard washable Blue Pure Fan particle filter capture 99% of airborne dust, pollen, and other household allergens. Not exactly HEPA grade, but you can feel the gradual improvement in the indoor air quality with just 20 minutes of air circulation. Replacing the filter is also easy as you only need to unplug, press the release button, lift off the back frame, and swap the old filter with the new one. There is no need to turn the machine upside down just to remove the filter. The apparent thing missing is an activated carbon filter that would help significantly against smoke and odors.

Using it as a fan, Blueair Pure Fan Purifying can be extremely subtle, with a whispering sound of around 31 dB(A). Blasting it to full speed, the noise output is at 56 dB(A), which is audible but still within white noise territory. Keep it low speed, and you can use it in the bedroom for uninterrupted sleep or anywhere that needs peace and serenity. Being an Energy Star Rated model, energy efficiency is one of Blueair Pure Fan's main forte. It can lower your room tempeature while keeping consistent low power consumption all day, even without auto or sleep mode.

Blue Pure Fan Pricing, Maintenance, And Drawbacks

So how much do you need to pay for this Swedish-inspired heritage? Around $200+ inclusive of the Blue Pure Fan particle filter. While it is not the most expensive device in a household, keep in mind that you probably can get a cheaper deal with a standalone air purifier and fan. As for the filter replacement cost, the particle filter set will set you back around 25 dollars every 6 months or 50 dollars annually. You can also get good filter discounts with the Blueair Filter Club loyalty program, which reduces the filter cost by up to 15% with an annual subscription. Very reasonable for Blueair standard.

A powerful fan/ air purifier that cools and cleans the air from airborne allergens. The exclusive Blue Pure Fan justifies its premium price tag with its minimalist approach. Ignoring the limited air-purifying functionality and the lack of smoke filtration, Blue Pure Fan Purifying Air Purifier is the perfect tool to accompany you on a long summer. "Get it while it is hot."

2. Blueair 605 Air Purifier

Blueair Classic 605 Air Purifier Review

Blueair 605 Features And Build Quality

Premium and classic design at its best. Blueair 605 retains its timeless console design from the previous version. At 20 x 26 x 13 inches in dimension, the air purifier occupies quite an ample space where it is impossible to squeeze it in a tight corner. Adding to that is the 35 lb galvanized steel body that feels hefty to move around the house. Unlike plastic that will off-gas at some point, the powder-coated exterior ensures no toxin emission. On the sides, there are air inlet and outlet plus bottom casters to ease its mobility. Build quality is top-notch with zero ozone emission, CARB certified, Energy Star rated, and 5 years warranty. As an added bonus karma point, Blueair 605 is also eco-friendly and made with 100% recyclable parts.

Blueair 605 control

Moving on to the controls and usability. There are only 3 big buttons, each with an LED icon indicating what mode the air purifier is in. Let's start with the middle air flow control button. The fan speed button will display complete grey if there is no power source (OFF). Outer circle blue with all bars grey when the power cable is plugged in. In operation (ON), 1 blue bar = minimum speed, 2 blue bars = medium speed and 3 blue bars = maximum speed. The same goes for the Wi-Fi mode, which will be in full grey when there is no Wi-Fi. The button will blink when it is ready to connect and blue if it is connected. As for the filter button, the color will be grey + blue when no replacement filter is required. Color changes to orange when the filter requires replacing. After changing, press and hold the button for 5 seconds to reset the status.

Available on iOS and Google Play, you can download the Blueair Friend app from the comfort of your bed. Once you have added 605 to the Blueair Friend app list, you can begin remotely controlling the air purifier. From essential functions like adjusting the 3-speed LED, display intensity, to direct timer. Advanced feature includes night mode, child lock, and scheduling (hours and days). Other passive features include real-time outdoor air quality data and usage logs. With the add-on purchase Blueair Aware monitor, you could enable the Auto mode feature. This lets the machine change speed autonomously to adjust to current room air quality.

Blueair 605 Filtration, Air Performance, And Noise

Being a console air purifier, there is multiple air inlet from the sides. It pushes Blueair 605 to deliver the best 150 to 650 cfm airflow delivery rate for its Classic series. At 775 sq. ft. coverage, it is perfect for large room sizes like living hall, dining room, lounge, basement, garage, or kitchen. There is plenty of power to spread out across the 3 fan speeds, so you will not feel underpowered. At 5 air changes an hour, clean air will be swiftly distributed across the room via the air purifier outlet.

CADR is equally impressive (above 500 points) and, again, the best in its Classic series. Dust CADR stands at 500 cfm, pollen CADR at a crazy 640 cfm, and smoke CADR at 500 cfm. Any figure that passes 300 cfm point is automatically qualified as excellent. Blueair 605 works best against seasonal allergies or hyperallergic/ asthmatic people.

The top-of-the-line from its Classic series. Blueair 605 HEPASilent Technology combines the effort between electrostatic and mechanical filtration. Nearby pollutants will first suck inside the air purifier via the motor fan. The encapsulated particle-charging chamber will straight electrically charge the pollutants. This resulted in the fine airborne pollutants more adhering to the particle filter. As a result, the filter will have an easy task in capturing them at 99.97% efficiency down to 0.1 microns in size like dust, mold spore, pollen, pet dander, bacteria, and viruses. The same goes for the highly porous structure of SmokeStop Carbon filter with active carbon pellets, which boosts efficiency with charged gas-based particles, including formaldehyde, cigaretter smoke, VOCs. Lastly, all filters are ultrasonically bonded with waterproof, natural antibacterial polypropylene fibers. In other words, antimicrobial protection. The opposite of most filters that use chemical-based bacteriostats/ mold inhibitors.

Continue on. All Blueair filter is made with a low, dense, gradient structure design. This prevents particles of all sizes from re-releasing, even if the filter is under heavy load. Blueair Classic 605 also helps reduce its surrounding ozone concentration level in the air.

For the high airflow output, 32 to 62 dB(A) noise level is much quieter than the similar range model. The low-density filter allows air to flow at a much lower pressure, and you can hardly tell the differences in real-life situations. Noise is whisper-quiet at low speed, normal at medium speed, and audible moving up the notch. Thanks to the advanced fan setup, 15 to 100 W power consumption is reasonable, given the airflow return. Without default auto mode, you will have to manually keep the speed low to help reduce electricity use.

Blueair 605 Pricing, Maintenance, And Drawbacks

A premium air purifier deserves a premium calling price, although I'm sure not everyone agrees. However, Blueair 605 price tag is not the biggest stumble block. The short filter lifespan and high annual filter replacement cost can greatly hinder its long-term ownership. To enjoy the Auto mode feature, you will need to buy the Blueair Aware monitor, pushing the price further. So if you can't cough out that much, sign up for the Blueair Filter Club loyalty program that help reduces the filter cost slightly.

In conclusion, we are happy with Blueair 605 air purifier's overall performance bar the price. It is exceptional for long-haul purifying, HEPASilent Technology filtration with 3-speed, Smartphone control, and ample airflow that pulls in anything from the path. It will make a difference against seasonal allergies. Consider the cheaper alternative, like 405 or 205, if you need a smaller, much more manageable unit.

3. Blueair Pro XL Air Purifier

Blueair Pro XL Air Purifier Review

Blueair Pro XL Features And Build Quality

Premium office air purifier it is, Blueair Pro XL is nothing short of that with solid build quality in and out. It is undoubtedly the most powerful Blueair model ever made. Stands very tall and heavy at 20 x 44 x 10 inches in size and 71 pounds in weight. While mobility is not great, Blueair Pro XL is exceptionally well-built, promising zero off-gassing and harmful particles escaping. With its tower profile, place it at a cover of the room and leave 2-4 feet of gaps. It will not obstruct your living space or office area.

Continuing with controls, usability, and functionality, Blueair Pro XL is also easy to use as it is basically two primary button operation machines. Turn on the unit by clicking on the PLUS button, and it will run at speed, with one blue bar light between the buttons. To increase/ decrease the speed, simply adjust between the PLUS/ MINUS buttons, and the blue light bar will update accordingly. To activate the Auto mode, click on the PLUS button on speed 3, and the word AUTO will light up, indicating the mode it is active. To deactivate auto mode, simply reverse the previous step. The two-bar columns display air suspended particles (PM2.5) levels and gaseous contaminants (GAS). 1 green bar equals good air quality, while 3 bars (green, yellow, and red) represent a high level of particles or gas). All displays will slowly disappear after 30 seconds and reappear when you click on any of the buttons. Lastly, a red filter light will light up when filter replacement is required.

Blueair Pro XL Filtration, Air Performance, And Noise

Being the largest and highest capacity Pro air purifier has its advantages. Blueair Pro XL has the most comprehensive purifying coverage to date (1180 sq. ft.) that can cover almost any room size from an entire home, meeting room, office, cafeteria, or lounge. Airborne particles are pulled in through the side inlet via three (YES 3) energy-efficient fans and released out at the other side of the outlet. At 5 air changes per hour, 210-990 cfm airflow is distributed evenly and swiftly by either a 3 manual speed or Auto mode.

Like the outstanding airflow performance, Blueair Pro XL has the highest overall AHAM-certified CADR we have ever reviewed. You have the Dust CADR at an amazing 950 cfm, pollen CADR at 900 cfm, and smoke CADR at 800 cfm. Incomparable stats, as you can see via the comparison table below.

As with Pro M and L, Blueair Pro XL is powered by the same HEPASilent technology that combines electrostatic and mechanical filtration. At a 99.97% effective rate of capturing particles as small as 0.1 microns, the purification began with the ionizer charging on any particles that travel in. With particles like dust mites, pollen, mold, and bacteria electrostatically charged, one of the 3 particle filters will effortlessly trap those none-gas based contaminants. The 3 SmokeStop filters will handle the rest of the smoke, chemicals, and odors based pollutants. At the journey's end, the air purifier will release cleaner air that contains even lesser ozone than before.

Like all Blueair filters, Blueair Pro XL filter media is made from waterproof, natural antibacterial polypropylene fibers rather than a chemical-coated base. The filters also come in a V-shaped design that prevents particles from escaping as there is more filtration depth under the same piece of a filter.

You would think Blueair Pro XL noise would be at an unsatisfactory level, given how strong its airflow output is. In actual fact, the 32 to 58 dB(A) noise level is more than reasonable, where low speed is whisper quiet and around normal conversation noise at max speed. Suitable for home and office use without any concern of noise pollution. Power consumption is clearly reflected in usage volume. At the power rate between 33 to 256 W, the higher the speed Blueair Pro XL runs, the higher the electricity bill will be. Fortunately, Air Intelligence Module is already bundled in, enabling Auto mode to optimize energy consumption.

Blueair Pro XL Pricing, Maintenance, And Drawbacks

Not for the faint-hearted, Blueair Pro XL is one of the most expensive air purifiers we have ever reviewed. It costs a whopping $2,499+ for a brand-new unit with a little discount available. Like all Pro series air purifiers, there is no Wi-Fi support, timer, or remote control as standard. Not recommended for home use unless you can fork out the cash. The same story goes with the filter replacement cost. It is at another level exceeding $1000 annually, beyond the reach of most ordinary folks. Make sure you can commit to the upkeeping before committing to the real thing.

To sum up, get this if you want the best of the best and have no issue maintaining one. While it's recommended for office use, only consider Blueair Pro XL for home if you are absolutely sure you can afford it.

4. Blueair Pro L Air Purifier

Blueair Pro L

Blueair Pro L Features And Build Quality

Blueair Pro L is an expensive, powerful, and elegant air purifier for office use or a niche target group. Like Pro XL, it shares the same impeccable build quality that can withstand continuous operation without breaking down. For all the performance it can churn out, the dimension is only 20 x 31 x 10 inches, smaller than a Blueair Classic series. The 46 pounds body weight is another story; it is undoubtedly heavy, which makes it hard to move around without casters.

Continuing with the design elements, Blueair Pro L is identical to the high variant in terms of ventilation position, colors, and features. You get a 3-stage HEPASilent filtration with zero ozone emission. As part of the deal, a 5 years warranty also comes standard that covers any manufacturing defects. The usual stuff.

On to Usability and functionality, Blueair Pro L is as simple as it gets, with only 2 buttons for fan speed control. How the control panel works is exceptionally straightforward. Click the PLUS button to turn on Blueair Pro L, and one blue bar (speed 1) will appear between the buttons. From there, you can adjust the fanspeed between 1 to 3 using the PLUS and MINUS buttons. To turn off the unit, simply click the MINUS button until no blue bar is left. For a unit with the Air Intelligence Module addon, you can activate Blueair Pro L Auto mode simply by clicking on the PLUS button until the indicator word AUTO appears. The air purifier will automatically adjust the speed according to the nearby contaminant levels. Also, with the AIM addon is the two bar columns that show the levels of air suspended particles (PM2.5) and gaseous contaminants (GAS). 1 green bar represents a low particle or gas level, while 3 bars (green, yellow, and red) represent a high level of particles or gas. The display will disappear after 30 seconds; simply click on any of the buttons to reenable the display. As for the filter replacement indicator, a red filter light will only appear when an annual filter change is required. There is no WiFi support, timer, sleep mode, or remote control bundled despite the premium price.

Blueair Pro L Filtration, Air Performance, And Noise

Abundant airflow distribution (140-660 cfm) is the sole reason you should gun for Blueair Pro L air purifiers. Supporting a maximum of 780 sq. ft. purifying coverage at 5 air changes an hour, Blueair Pro L is ideal for all situations and places. Leave it in a restroom, home office, meeting room, or conference room to see an instant improvement in indoor air quality. Along with the strong airflow delivery rate, Blueair Pro L air purifier CADR is only second to Pro XL. All figures exceed the 400 level points, starting with dust CADR at 630 cfm, pollen CADR at 600 cfm, and smoke CADR at 490 cfm. As long as the airborne contaminants fall within its purifying range, Blueair Pro L can quickly spread and distribute clean air across the room.

What's powering Blueair Pro L is the highly acclaimed 99.97% efficient rate HEPASilent technology along with Particle and SmokeStop filter. Both electrostatic and mechanical filtration will join side by side in combating airborne contaminants. Airborne particles flown inside the air purifier would be subject to electrostatic charge and, therefore, more clingy to the filter. The Blueair particle filter will now have an easy task trapping micron-size allergens, bacteria, and viruses. The SmokeStop filter will focus on absorbing gases and odors instead. At the end of the cycle, Blueair Pro L will release cleaner, purified air that contributes even less ozone than normal unpurified air.

Overall, filter quality is up there with the best. Blueair Pro L filter media is ultrasonically bonded and made with waterproof, natural antibacterial polypropylene fibers. The antibacterial agent ensures no mold and bacteria growth on the filter. The V-shaped filter design allows more particles to be captured and prevents the trapped particles from escaping, even during filter change.

Powering the 3-speed air purifier are the energy-efficient motor fans that draw particles via the side air inlets. Blueair Pro L 32 to 55 dB(A) noise level is surprisingly low, given how strong and punchy the airflow delivery is. Thanks to the German Engineered fans, it is whisper quiet at low speed, while at max speed is no more than normal conversation. The air cleaner will not disturb your work or sleep routine. On the other hand, the 22-170 W power consumption is moderate to high, depending on the speed Blueair Pro L is running. At max speed, the air purifier drains a fair share of electricity, especially if you are running 24x7. If you have any energy concerns, we recommend purchasing the addon Air Intelligence Module to enable the energy-efficient Auto mode.

Blueair Pro L Pricing, Maintenance, And Drawbacks

The "mid-range" premium office air purifier is anything but mid-range. An exceptional air purifier it may be, Blueair Pro L is very expensive for home use before we even include the addon cost for the optional Air Intelligence Module. Blueair Classic 605 would be a better value for home use as it comes with more features e.g. WiFi support, auto mode, and timer. Annual filter replacement costs are also skyrocketing at $400+ (double filters for both Particle and SmokeStop). You could buy at least 2 decent brand-new air purifiers yearly.

To conclude, office bound Blueair Pro L is a solid HEPA air purifier, but it's simply too expensive for an average joe like us. Consider this if you truly appreciate the extraordinary performance over the high price.

5. Blueair 205 Air Purifier

Blueair Classic 205

Blueair 205 Features And Build Quality

The smallest and lightest Wi-Fi-ready air purifier in its Classic stable. Blueair 205 air purifier stands at a much compact 17 x 21 x 8 in size and 24 lb in weight. It fits most homes well, including those with limited spaces. Made entirely from galvanized steel that guarantees no chemicals off-gassing, Blueair Classic 205 build quality is exceedingly durable for long-term ownership. No cutting cost measure as the fitting is the exact as the higher-end variant with zero ozone emission, CARB certified, ENERGY STAR rated, and 5 years warranty. Best of all, you can fully recycle the air purifier when it reaches its lifespan. As for mobility, Blueair 205 is still considerably bulky, although far from the worst. It has side handles that would work even better if casters were included (optional purchase).

Like all Classic models, there are 2 ways of controlling the air purifier. However, we will focus on the second method later on. The first and most common way is using the main buttons via its top control panel. You can control the fan speed, connect to your Wi-Fi devices and check filter status. Each button comes with a live LED display that will show the mode you are currently in. To further elaborate, let's start with the fan speed button. 1 blue bar will light up if you are at the first speed, 2 blue bars for the second speed, and so on. The LED blue light will continue to blink for the Wi-Fi button if it is ready to connect and stays blue when connected. For the filter button, the LED icon will light up in grey + blue by default and change to orange when a replacement filter is needed. To reset the filter button, simply hold the button for around 5 seconds.

As mentioned earlier, Blueair 205 is Wi-Fi ready, and you could pair it with your smartphone to operate the air purifier remotely. Available on Android and iOS, download and install the Blueair Friend app on your mobile phone. Once everything is in order, you can adjust the fan speed, LED brightness intensity, set up the timer, enable/ disable child lock, night mode, and advanced scheduling on either hours or days. Besides that, you can keep track of outdoor air quality in most major urban areas and a few other miscellaneous AQ logs. If you have the optional Blueair Aware monitor, you can also enable Auto mode for autonomous operation and monitor room air quality based on your various indoor activities.

Blueair 205 Filtration, Air Performance, And Noise

While both Blueair 405 and 605 has excellent purifying coverage, Blueair 205 has a moderate purifying coverage catered for medium size room. At 280 sq. ft. applicable area, Blueair Classic 205 would be best suited for a bedroom or any room size that does not exceed the recommended coverage. The 3-speed 75 - 220 cfm airflow delivery is consistent with the output. Anticipate an average dust clean air delivery rate of 200 cfm, pollen CADR at 200 cfm, and smoke CADR at 180 cfm. Decent return for home use, even though it fairs the worst on this list.

Blueair 205 Classic air purifiers utilize the same HEPASilent technology that promises a 99.97% efficiency filtration rate against particles as small as 0.1 microns. It combines electrostatic and mechanical filtration, where incoming particles will be electrostatically charged first-hand. With all particles charged, pollutants like pollen, mold, germs, pet dander, and dust mites will be more clingy to the filters, thus reducing the chances of these particles getting away. The same theory would be applied to the SmokeStop filter with active carbon pellets, focusing on neutralizing chemicals, smoke, and odors, including formaldehyde, VOCs. Additionally, The filters are designed in gradient structure and thermally bonded, preventing particles from escaping even under heavy load circumstances. Another benefit of the Blueair 205 filter is it uses natural anti-bacterial polypropylene fibers, which are incidentally waterproof. Bacteria and mold would be inhibited from growth as these microorganisms require water to thrive. Finally, Blueair Classic 205 Smokestop would also slightly reduce the surrounding ozone level by releasing cleaner air.

Despite being the smallest Wi-Fi Classic air purifier, Blueair 205 noise level is similar to the higher-end variant at 32 to 56 dB. At low speed, it's perfectly silent without fan noise disturbing your daily routine, and the noise is clearly audible as you move up the level. Suitable for baby and bedroom use. The same pattern with the power consumption. It uses less than a light bulb at around 20 to 80 wattage. Far more efficient than your air conditioner, oven, or washing machine.

Blueair 205 Pricing, Maintenance, And Drawbacks

Blueair classic 205 air purifier is the cheapest Wi-Fi-ready air purifier in its Classic series. However, many more affordable alternatives from Winix, Airmega, and Honeywell have broader purifying coverage. None offers the trademark HEPASilent technology, so if that is what you want, 205 is your only option. As for Blueair 205 filter replacement cost, both particle filters are considerably expensive, but they are still the least costly in the Classic range. Like most Blueair Classic air purifiers, you can purchase an additional Blueair Aware monitor that adds auto and AQI features.

To round up, Blueair Classic 305 is a premium air purifier that greatly improves your home air quality issue. Its main drawback is the cost, which will impact the product's longevity. If you are comfortable with the annual $300 filters maintenance, The Blueair brand will not fail you.

6. Blueair 405 Air Purifier

Blueair Classic 405

Blueair 405 Features And Build Quality

Want something cheaper than 605 but better than 205's offering. Blueair classic 405 is your answer. It is essentially the same setup with standard 3-stage HEPASilent Technology, CARB approved ozone-safe and 5 years warranty. Built with fully recyclable galvanized steel that will not release toxins like its plastic-based counterpart. The 20 x 23 x 11 inches is also between 205 and 605 in dimension. Hardly considered compact, but still suitable for home use as long as you don't place it under a shelf due to its 33 lb weight. Not the best option for room-to-room air-purifying due to the lack of casters.

Continue with controls and usability. The Blueair 405 air purifier can be controlled either remotely via smartphone (more on this later) or through the physical control panel at the usual top spot. Each button is clearly labeled with a live LED icon update. The fan speed LED icon will display 1 blue bar at the first speed, 2 blue bars at the second speed, and 3 blue bars at the third speed. As for the middle Wi-Fi button, the LED icon will remain grey if there is no Wi-Fi, blinking when it is ready to connect, and blue when it is connected. Finally, the filter LED icon will light up in grey + blue when no replacement filter is needed and change to orange when there is an imminent filter change. Simply hold the button for 5 seconds to reset the LED status.

Blueair Classic 405 Wi-Fi supports remote access via your smartphone. By installing Blueair Friend app on either Android or iOS, you could adjust the 3 airflow speed, LED brightness intensity, set up a timer, activate/ deactivate child lock, night mode, and change speed/ LED at specific hours/ days. For "I" series models with built-in sensors or the optional Blueair Aware monitor, you could enable Auto mode for autonomous operation, monitor, and keep track of room air quality. The straightforward controls that we have been familiar with for years.

Blueair 405 Filtration, Air Performance, And Noise

Blueair 405 has an equally impressive 120 to 350 cfm airflow delivery rate contributing to the wide 430 sq. ft. purifying coverage at high APH. Ideal for large room sizes, including living room, master bedroom, lounge, or kitchen. At 5 air changes an hour, airflow is consistent and fully adjustable via the standard 3 fan speed. The clean air delivery rate is equally remarkable tally with the airflow delivery rate. The dust and pollen CADR stands high at 300 cfm, while the smoke CADR is at 280 cfm. Hyperallergic or asthmatic people can truly benefit from the strong return.

The renowned HEPASilent Technology removes 99.97% of unwanted airborne particles as small as 0.1 microns via electrostatic and mechanical filtration. It electrostatically charges any incoming pollutants before passing them on to the filter media. Charged contaminants like mold, pollen, pet dander, and mites will be more clingy to the particle filter, thus increasing the capturing efficiency rate. Likewise, the SmokeStop Carbon filter will be more efficient in absorbing smoke, gas, odors, and chemical fumes like formaldehyde, radon, VOCs. Instead of using chemical-based bacteriostats that inhibit bacteria and mold growth, Blueair 405 filters are made with natural, waterproof, anti-bacterial polypropylene fibers. Additionally, the thermally-bonded, gradient structure filter design prevents particles from escaping the filter despite the heavy load.

Regarding noise and power, the 32- to 52 decibels noise level is good thanks to the lower density filter and fan placement. A similar range model usually has higher noise output at higher/ maximum speed. To enjoy a virtually silent operation, keep Blueair 405 at low speed for an uninterrupted air cleaning. The 15 to 90 watts power consumption is also impressive, which uses less than a light bulb. Expect an increase in utility bills of not more than a few dollars a month.

Blueair 405 Pricing, Maintenance, And Drawbacks

Blueair 405 air purifier is cheaper than 605, about $300. A significant difference in the selling price for an air purifier with identical features. If you can cope with the smaller purifying coverage, Blueair 405 would be a good buy. On the other hand, the annual filter replacement cost is darn expensive at over $300. In a short period of 2 to 4 years, the air purifier maintenance cost would quickly exceed the original cost of the air purifier. On top of it all, one must purchase Blueair Aware monitor (sold separately) for autonomous mode. Again, if the Blueair brand is a must, yet you have a smaller budget, consider the smaller Blueair 205. There is no wrong option.

Blueair Sense+ Air Purifier

Blueair Sense+ Air Purifier Review

“Modernistic” might not be an actual word, it represents how we see Blueair Sense+ on its premium build materials, elegant seamless grill, and motion sensors control (more on this later). Designed by Internationally-acclaimed Swedish designers Claesson Koivisto Rune, Blueair Sense+ is also very compact at only 18.5 x 19 x 7 in size and 24 lb. It could easily blend into your home decor thanks to the various color palette options (Graphite Black, Leaf Green, Midnight Blue, Polar White, Ruby Red, Warm Grey). Control and usability-wise, Blueair Sense+ is very easy to use, although it could take some time to get used to. To turn on Blueair Sense+, swipe on the top control panel once, and a blue light will light up, indicating the air purifier is running at speed one. Repeat the step to increase the fanspeed up until speed 3 where the air purifier will turn off on the next swipe. Besides the motion control panel, there is also Wi-Fi with indicator, filter change indicator (based on actual indoor pollution and real-time use), 3-stage filtration, zero ozone emission, CARB certified, ENERGY STAR certified, and 5 years warranty.

Blueair Sense+ is Wi-Fi enabled, so naturally, it supports the company Blueair Friend app or Amazon Alexa. Available in the App Store and Google Play, the apps help transform your smartphone into a remote control. Via the Blueair Friend app, you could remotely change the 3 airflow speed, timer, activate child lock/ night mode, schedule speed/ LED at specific hours and days. You could also access indoor/ outdoor air quality data in most major urban areas and a few other miscellaneous logs/ tracking. With the optional Blueair Aware monitor, Auto mode feature is possible to monitor and change the air purifier speed autonomously based on your indoor pollution level.

Blueair Sense+ has a decent mid-range level purifying coverage at 186 sq. ft. It loses out to many top-tier air purifiers, but it’s understandable given the small boxy framework. On a positive note, the motion-powered 3 speed does deliver solid and consistent 35-150 cfm airflow distribution that you would expect no less from Blueair. Fair to say that Blueair Sense+ is more a bedroom than a full living room air purifier.

As with the airflow delivery rate, CADR return is decent but not spectacular. You have the dust CADR at 140 cfm, pollen CADR at 150 cfm and finally, smoke CADR at 120 cfm. Feel free to compare that CADR stats with other air purifiers via the compare button above.

Like Blueair Sense, Blueair Sense+ uses HEPASilentPlus technology, essentially an electrostatic and mechanical hybrid filtration. Instead of using 1 set of filters, Blueair Sense+ uses 2 waterproof, natural antibacterial polypropylene fiber particle filters that each come with an active carbon sheet specifically for gaseous form pollutants. At a 99.97% effectiveness of capturing particles as small as 0.1 microns, incoming particles like germs, smoke, odor, and bacteria will be trapped by the initial particle filter. Particles that manage to bypass the filter will be ionized by the ionizer and subsequently captured by the second particle filter. At the very end of the cycle, Blueair Sense+ will release out purified air that contains even lesser ozone than surrounding unpurified air.

Replacing the filters is slightly tricky as the front panel is non-removable, unlike most air purifiers. You would need to turn off the device, pull out the power plug, put the unit down with the backside facing up, open the bottom cover, and remove the 2 filter cassettes. Thankfully it’s a half to yearly job, depending on how bad your indoor air quality is.

Blueair Sense+ has a typical Blueair filtration setup, meaning the 29 -50 dB(A) noise level is reasonably subdued. The air purifier is whisper quiet at low speed, and the noise level will increase no more than normal conversation as the speed increases. Power consumption is actually pretty good, around 7-45 watts. For long-term energy-saving operation, it would be wise to invest in Blueair Aware, where you could rely on the machine to optimize the purifying speed based on the surrounding environment (in other words, Auto mode).

Blueair Sense+ might not be the most expensive air purifier, but for its airflow performance and purifying coverage return, there are far better options available (don’t get us started on the optional Blueair Aware). Annual filter cost is between reasonable to slightly expensive depending on the surrounding environment and usage frequency. On the whole, if you value premium build quality and compactness, Blueair Sense+ is no doubt the right choice for you.

Things To Look For In Blueair Purifiers

Every Blueair air purifier can significantly improve your indoor air quality. However, finding the right Blueair model can be challenging as you invest a lot of money. To help you get started, the guide below will help you identify which models would best suit your home.

  • Dimension - Blueair purifiers can be bulky, especially on the higher-end series. Always measure your room size and pick a model in which you can fit the air purifier without taking up much room space.
  • Weight and portability - Though some model comes with casters, a Blueair air purifier can weigh up to 71 pounds, making it almost impossible for room-to-room purifying. If you need an air purifier to carry it around, try brands like Levoit or GermGuardian.
  • Pricing - Quality comes at a price, especially when it is made in Sweden. Blueair models are on the premium side, from $200 to $2000 and above for its top-of-the-range model. It is not for everyone.
  • Recurring filter cost - The same goes for the filter replacement cost. Blueair filters are known for their quality and high price. Consider other more budget-friendly brands if you cannot afford to fork out hundreds of dollars yearly for replacement.
  • Suggested room size - There's a model for everyone. Blueair purifier air-cleaning coverage varies depending on the models. If you need to clean the air in a smaller room, pick 205 or 405; pick 605 if you need to purify the air in a larger space. Refer to the manufacturer's suggested room size for more info.
  • Clean air delivery rate (CADR) - A numerical metric developed by AHAM to measure the air cleaning performance of an air purifier. The higher the ratings, the more airborne pollutants will be removed. Use this to calculate the room size an air purifier can cover.
  • HEPASilent technology - A trademark feature available in all Blueair models. Divert your attention to the filter size instead.
  • Noise and energy usage - Most Blueair purifiers are silent and efficient at low speed. If you are sensitive to both, pick a smaller model for an interrupted operation.
  • Warranty - Blueair purifiers come with a standard 1-year warranty and can be further extended to 5. However, you will have to renew with official Blueair filters timely as part of the T&C. Keep this in mind.

What Does The Red Light On Blueair Purifier Mean?

Blueair Classic air purifiers series come equipped with the Air Quality Indicator. It will light red when the sensor detects an increase in airborne particulates nearby.

Why Is My Blueair Filter Orange?

In Blue, JOY, Pure models, the filter light turns yellow/ orange after 5-6 months of continuous use, indicating it is time to replace it with a brand-new filter. If the particular model is WiFi enabled, you will be notified via the Blueair Friend app prior, so there is sufficient time to order a new filter set.

Is Levoit Or Blueair Better?

Both serve a different target group and are good, respectively. Levoit focuses on entry-level to mid-range with models like Core 300, Vital 100. It is cheaper, smaller, and quieter than Blueair. Blueair target the premium segment with models like 605, 411. It is bulkier, much more expensive, and noisier at higher speeds, but you get better filtration and performance out of it.

Do Blueair Air Purifiers Release Ozone? Is It Safe?

All Blueair air purifiers comply with the EPA (United States Environmental Agency) requirement and are CARB certified to be safe. It does not exceed ozone emission limits. While ionizer technology is integral to the SilentHEPA technology, Blueair has conducted independent testing to ensure its air purifiers do not release harmful ozone levels. In fact, studies have shown that Blueair purifiers with a SmokeStop filter can reduce ozone concentrations in indoor air.

Why Is Blueair Not HEPA?

Blueair's HEPASilent technology relies on loose filters combined with ionization technology. It differs from True HEPA filtration, which relies on tightly fitting mechanical filters to trap particles. In terms of effectiveness, Blueair purifiers perform exceptionally well with the HEPASilent filtration system; much better than HEPA; it delivers a higher volume of clean air, as shown in the AHAM-certified CADR. The electrostatic and mechanical filtration combination removes at least 99.97% of airborne microscopic particles down to 0.1 microns, including bacteria, viruses, and microplastics.

What Country Is Blueair?

Blueair originates in Sweden and is renowned for its top-notch performance, innovative technology, and minimalistic design. Contrary to many beliefs, Blueair is not a China company; it is actually a US company located in Chicago, Illinois, United States. Blueair purifiers are designed, engineered in Sweden, and assembled in China.

What Is The Difference Between Blueair 311 And 411?

As the name rightly suggested, Blue 411 is the higher variant of Blueair 311 with a slightly larger dimension, wider recommended room size ( 388 sq. ft.), and better CADR. Features like an air quality indicator, auto mode, and particle sensor remain the same.

What Is The Difference Between Blueair 411 And 411+?

The more expensive + variant comes with an increased Clean Air Delivery Rate (CADR) and room size capacity (185 sq. ft.). Otherwise, it is the exact model.

What Is The Difference Between Blueair 211 And 211+ Auto?

As the name implies, The upgraded + Auto version features an integrated particle sensor, enabling Auto mode and air quality indicator.

How Long Do Blueair Filters Last?

6-12 months, depending on the air quality and usage time. For the best result, Blueair recommends changing the filter every 6 months or when the filter light indicates it is time to replace your filter. You will be glad to know that all Blueair filters are eco-friendly as it is made mainly of polypropylene. Please bring them to your local recycling center and recycle them as a 5 or a 7.

What Is Blueair Night Mode?

Blueair night mode minimizes noise disturbances by using a lower speed to clean the air discreetly between 9 pm and 8 am. Night mode can be enabled automatically with the Welcome Home feature, allowing a person to sleep soundly while breathing clean air.

Can I Vacuum Blueair Filter?

Yes, you may vacuum the Blueair filters with a HEPA vacuum cleaner. Gently vacuum the surface area to remove as many dust particulates as possible. Fabric pre-filter can be washed carefully with a low-temperature cycle washing machine. You will still have to replace the Blueair air filters every 6 months for optimal filtration performance.

Is It OK To Leave Blueair Air Purifier On All Night?

Yes, it is OK to leave a Blueair on all night, 24x7, with no health repercussions. It will ensure dirty air pollutants stays trapped and do not build up overnight while you sleep. The ozone emission limit is negligible and will dissipate quickly. The only thing you need to ensure is that the filters are replaced accordingly. Otherwise, there is no point in leaving it on.
