Blueair Classic 205 Review In 2022

Design And Usability

The smallest and lightest Wi-Fi ready air purifier in its Classic stable, Blueair 205 air purifier stands at 17 x 21 x 8 in size with 24 lb in weight. Made from galvanized steel that guarantees no chemicals off gassing unlike most plastic materials, Blueair Classic 205 has one of the best build quality around and is exceedingly durable. 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 it comes with side handles that would work even better if casters is 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 buttons comes with 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 in first speed, 2 blue bar for second speed and so on. For the Wi-Fi button, the LED blue light will continue to blink if is ready to connect and stays blue if is connected. Finally for the filter button, LED icon will light up in grey + blue by default and change to orange when replacement filter is needed. To reset the filter button, simply hold the button for around 5 seconds.

Other standard features you would find include a 3-stage filtration with HEPASilent Technology, 3 speed, smartphone integration, filter replacement with no screws needed, filter replacement indicator, zero ozone emission, CARB certified, ENERGY STAR rated and 5 years warranty.

Blueair Friend app

As mentioned earlier, Blueair 205 is Wi-Fi ready where you could pair with your smartphone to operate the air purifier remotely. Available in both Android and iOS, first you have to download/ install Blueair Friend app on your mobile phone. Once everything is in order, you could adjust the fan speed, LED brightness intensity, setup timer, enable/ disable child lock, night mode and finally advanced scheduling for speed/ LED based on either hours or days. Other than that, you can keep track outdoor air quality in most major urban areas and 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.

Airflow, Coverage, And CADR

While both Blueair 405 and 605 has excellent purifying coverage, Blueair 205 on the other hand has a moderate purifying coverage catered for medium size room. At 280 sq. ft. applicable area (5 air charges per hour), Blueair Classic 205 would be best suited for bedroom or any room size that does not exceed the recommended coverage. The 3 speed 75 - 220 cfmairflow delivery is consistent with air coming in from bottom, back and side of the air purifier.

Moving on to the CADR, expect an average of dust clean air delivery rate at 200 cfm, pollen CADR also at 200 cfm and smoke CADR at 180 cfm. Decent return although far from the best which you could compare via the specification table above.

Filters And Performance

All Classic air purifier utilize the same HEPASilent technology that promises 99.97% efficiency filtration rate against particles as small as 0.1 micron. No exception here as it combines electrostatic and mechanical filtration where all incoming particles will be electrostatically charge. With all particles charged, pollutants like pollen, mold dust mites will be more clingy to the filters thus reducing the chances of these particles from getting away. Same theory would applied to the SmokeStop filter where it will focus on chemicals, smoke and odors instead. Additionally, The filters is designed in gradient structure and thermally bonded which further prevent particles from escaping even under heavy load circumstances. Another benefits of Blueair 205 filter is it uses natural anti-bacterial polypropylene fibers which is incidentally waterproof. Bacteria and mold would be inhibit from growth as these microorganism require water to thrive. Finally Blueair Classic 205 Smokestop would also slightly reduce surrounding ozone level by releasing cleaner and less ozone concentrated air.

Noise And Energy Usage

Despite being the smallest Wi-Fi Classic air purifier, Blueair 205 noise level is similar at 32 - 56 dB. At low speed, it's perfectly silent without any fan noise while noise is clearly audible as you move up the level. Same pattern with the power consumption, power used is less than a light bulb at low speed while at around 20 - 80 W if you toggle between the speed during operation.

Pricing And Maintainence Cost

Blueair classic 205 air purifier is the cheapest Wi-Fi ready air purifier in its Classic series however, there are many cheaper alternatives with wider purifying coverage that you could also considered. As for Blueair 205 filter replacement cost, both particle filters are considerably expensive but it is still the least expensive in the Classic range whether in 6 months’ time or 1 year. Like most Blueair Classic air purifier, you can purchase a Blueair Aware monitor to check surrounding air quality or enabled hidden Auto mode feature via Blue Friend app.
