How Do We Measure?

Dimension The average bedroom size in the United States is 132 square feet. Most bedroom-centric air purifiers would be able to cover that but you will need to account for bed, wardrobe, or table lamp that occupy the space in a room. As such, we always recommend picking an air cleaner that has a higher airflow and room capacity to balance the in-room obstruction.
Noise level The level of noise outputted is a very important consideration for bedroom air cleaners. The ideal decibels will be below 35 dB with a reasonable airflow delivery rate. As every bedroom will differ in spaces, we will measure the noise level at the lowest, maximum speed, and do the performance comparison of everyday use.
Sleep mode Sleep mode is a useful feature that will maintain the fan speed to low but still capable of tackling impurities in the air. When operated at the lowest speed, the featured model must be adequately silent so owners can run it without having to worry about excessive noise. Some Sleep mode automatically dims down on the indicator brightness when you turn off the room light. We appreciate that too.

Winix 5500-2 is always the first in our consideration list for many good reasons. It has a decent 53 to 226 cfm airflow output and a wide 360 square feet coverage that can cater to a large bedroom. Supporting that is the impressive CADR at 243 cfm dust free, 246 cfm pollen free, and 232 cfm smoke free. You can even use Winix 5500-2 to cover multiple bedrooms on the same floor providing all doors are opened.

Suitable for bedroom use, the noise level stands at 26.6 decibels at the lowest speed to 60+ decibels at max speed. If you have any concerns about the fan noise, both auto mode and sleep mode are available to help curb down the background sound. In auto mode, higher fan speed will only be activated once the sensor detected a high level of pollutants in the air. In sleep mode (activate when lights are off), the fan speed will automatically set to low with reduced indicator brightness on the indicator. Energy consumption is low averaging around 5 watts to a max 90 watts on high speed.

Here is the featured spec sheet of Winix 5500-2 PlasmaWave:

  • Dimension (W x H x D) - 15 x 23.6 x 8.2 in
  • Weight - 15.4 lb
  • Noise Level - 26.6 to 60+ dB
  • Sleep Mode - Yes (Auto)
  • Filtration - Pre-filter, True HEPA filter, AOC Advanced Granular Carbon Filter, PlasmaWave Technology

Powered by the familiar 4-stage PlasmaWave filtration like most Winix models in the lineup. The initial pre-filter would trap large particles like dust, lint, fiber, and hair while extending the HEPA filter lifespan. The protected True HEPA filter will now focus on removing 99.97% of airborne irritants down to 0.3 microns that are flowing above your sleep area. Next, the deodorization AOC Carbon filter will effectively adsorb smoke and toxic gases like ammonia, radon, VOCs, CO, CO2. Finally, PlasmaWave technology would emit Hydroxyls to assist in dismantling the molecular structure of chemicals, germs, and odors.

In spite of having so many filters in the body, Winix 5500-2 is not too bulky that will occupy a large chunk of your room size. At 15 x 23.6 x 8.2 in dimension and 15.4 lb weight, you can place it further away from the bed while still enjoy full-fledged clean air. The conventional side air inlet with a back air outlet works well in Winix 5500-2 black housing setup. Overall the build quality is good that will last you many nights of good sleep.

Being one of the more stylish bedroom air purifiers in the market, Winix 5500-2 is well-equipped with practical features such as remote control, air quality indicator, filter change indicator, and timer that can help enhance the usability of the air cleaner so you will spend more time doing the things you loved. . The 1, 4, 8 hours timer is particularly useful to set before you hit the sack and can be set at the comfy of your bed. The official 2 years warranty is assuring, to say the least.

There are not many faults you can find here. If you are being picky, the annual filter replacement cost can stack up quickly for the coming years. The carbon filter is not the quickest in removing odor but no big deal since the smell will be clear out eventually when you kept it running throughout the night.

An air purifier may not be all the answer to your sleeping disorders or excessive daytime sleepiness. But if you experience breathing irregularity and sweat during sleep, Winix 5500-2 might be able to help. Without the harmful particulates pestering your sleep, you will breathe more smoothly and wake up feeling completely refreshed.

In short: For less than 150 (after discount), Winix 5500-2 is budget-friendly without compromising on any practicality. The strong and silent airflow performance is good to cover all bedroom sizes.

If you like 5500-2 yet need a much slimmer profile air purifying device, GermGuardian AC5250PT Pet Pure is your go-getter. The capable yet whisper-quiet air purifier will ensure you many nights of uninterrupted sleep in the bedroom. At only 6.1 inches in width and 9.5 inches in depth, there is no issue finding a place for GermGuardian AC5250PT in the chamber. The 10.5 lb weight is not the lightest, but you can still carry it from room to room that needs air purifying.

Controls wise, even though there is no auto/ sleep mode, you still have a highly adjustable 5 fan speed, 1 to 8 hours programmable timer, digital display, and a filter reset button that is only used after you changed the filter. To keep the noise level down during sleep, manually set the fan speed to low and the air cleaner will operate silently throughout the nighttime. Power consumption will be based on the fan speed you are constantly in but it will be in the energy-efficient bracket. Another thing that we liked about GermGuardian AC5250PT is the comprehensive 5 years manufacturer warranty. A step up from the previous AC4825 3 years offering with the same coverage on parts and motors.

Let's explore the key features of GermGuardian AC5250PT Pet Pure:

  • Dimension (W x H x D) - 6.1 x 27.3 x 9.5 in
  • Weight - 10.5 lb
  • Noise Level - Silent
  • Sleep Mode - No
  • Filtration - Charcoal pre-filter, True HEPA Filter with Pet Pure antimicrobial, UV-C Technology

GermGuardian AC5250PT Pet Pure is best for pet owners that sleep with their pets. The 5-stage air cleaning system offers a modest 180 square feet room coverage with 123 cfm dust free, 128 cfm pollen free, and 116 cfm smoke free. While the numbers might not seem a lot, for bedroom use it is perfectly fine. Going through the filtration, the outer charcoal pre-filter will capture dust, hair, mild smoke, and odors. By filtering out all the large impurities, The HEPA filter can efficiently remove 99.97% of microscopic particles as small as 0.3 microns including dust mite, pet dander, pollen, and mold spore. The HEPA filter is also coated with an antimicrobial that inhibits the growth of microbes in the filter. Finally, the UV-light will kill any inflowing bacteria and viral viruses that can aggravate your allergies. The entire purification process works very well especially if you have indoor pets like a cat or dog that sheds every single day. It will capture airborne pet hairs and reducing the chance of you inhaling them or sticking on your pillow, bedsheet, floor.

There are always pros and cons in an air cleaner. No exception with GermGuardian AC5250PT. The carbon pre-filter is not the best against smoke and odors, especially if your bedroom is in the basement. The filter also requires more frequent change between 6 to 9 months. Airflow output is not the greatest and there is no autonomous at all. Lastly, the 50 to 80 dollars filter replacement cost might be slightly pricey for someone that needs a basic air cleaner for bedside use.

Nobody can live without sleep. Good quality sleep is crucial to maintain healthy wellbeing. If you are still not sleeping well despite having GermGuardian AC5250PT Pet Pure presence in the bedroom, air quality may not be the main issue. Consult a sleep specialist to understand your situation.

In short: A cost-effective and silent bedroom air purifier for allergies with a complete 5-stage filtration system. Perfect for pet owners that have pets sleeping on their bed.

At only 3.2 lb in weight, it is very easy to carry PARTU BS-03 around during travel and use it in a hotel room for a good night sleep. Having smaller filters also means you don't need to accommodate a big fan. That itself will help keep the energy consumption low to support the spinning fan.

Essential oil can help you sleep better, relax, alleviates insomnia, and reduce anxiety. Choose from the long variety of Citrus, Honeydew Melon, Quince, Musk, Vanilla, Orris, or Vetiver.

There is even a button that will disable the indicator light to avoid the glaring distraction during your sleep. However, it is still a basic model that has limited functionality, airflow delivery rate, and purifying coverage. You will not find any autonomous feature other than the 3 fan speeds.

Coway Mighty AP-1512HH is our best bedroom HEPA air purifier for a good reason. For less than $200 after discount, it is modestly priced given the outstanding airflow and filtration performance you will get. No other air purifiers came close to what Coway is able to offer.

At 16.8 inches in width, 18.3 inches in height, 9.6 inches in depth, and 12.3 pounds in weight, it can be cumbersome when placed in a small bedroom. The bulky size is unavoidable in order to fit in full-size filters and a huge fan. Most people will leave it inside the bedroom where they will spend the most time in.

Moving to the features, Coway AP-1512HH comes with a dedicated HEPA and Odor filter replacement indicator to let you know which filter requires replacing, 3 preset timers that can be set when to turn off the device, and a smart air quality indicator. The AQ indicator turns blue when the air is clean, purple when air quality is at a medium level, and red when the air quality is bad. As for the usability, the silence operation will only output 24.4 dBA at the lowest setting and a max 53.8 dBA at high speed. You can leave Coway AP-1512HH air purifier running in the bedroom all night without any disruption.

Let's jump straight into Coway Mighty specification:

  • Dimension (W x H x D) - 16.8 x 18.3 x 9.6 in
  • Weight - 12.3 lb
  • Noise Level - 24.4 - 53.8 dBA
  • Sleep Mode - No
  • Filtration - Pre-filter, True HEPA filter, Deodorization filter, Vital Ionizer

This boxy-shaped device might not seem as capable as other air cleaners, is what's inside that counts. The advanced 4-stage air filtration will swiftly trap indoor pollutants within its wide 326 sq. ft. room coverage. First, you have a permanent, washable pre-filter that can capture large particles like dust, fur, fiber, and hair while protecting the HEPA filter. Second, The True HEPA filter will remove 99.97% of the microscopic particles in the air as small as 0.3 microns including mold spore, pollen, pet dander, bacteria, and viruses. Third, the activated carbon filter traps toxic gases and fumes coming from cigarettes, cooking, pet, household detergent. Finally, the vital ionizer will diffuse negative ions to electrically charge air molecules. The charged particles will sink due to the increased weight assisting the air cleaner for easy capture. You can switch off the ionizer via the center Ionizer button. With the standard 3 fan speeds, the official CADR by AHAM is at 246 cfm (dust), 240 cfm (pollen), and 233 cfm (smoke).

There are still more things we liked about Coway AP-1512HH. Comes in a 3 years warranty is a good assurance of the product's build quality. The annual filter replacement cost is less than 50 dollars despite having multiple filtrations. Power consumption can be as low as 4.9 watts with Energy Saving Eco mode that will shut down the device when there is no air pollution detected for 30 seconds. The Smart Particle sensors also allow Auto mode where the fan speed will automatically set to high when nearby pollutants are on the rise.

The "main" thing missing is the sleep mode that will lock the fan speed to the lowest and dim the indicator light. Other than that, the short 6 months carbon filter lifespan and dated design can be a little bit annoying. Some users might prefer a newer released model with an updated design. All in all, when a device is already a few years old and still selling well, there is something special about it. If you have difficulty falling asleep from nasal congestion or night cough, give Coway AP-1512HH Mighty a shot.

In short: One of the best air purifiers for bedroom with exceptional performance and price. Slightly dated and bulky but it comes with a genuine True HEPA filter that works well with auto mode.

Levoit might not be the biggest household name that everyone is familiar with, they do release some exceptional value model. One of them is the simple and sleek-looking Levoit Core 300 air purifier. An affordable, well-built, compact device that comes with a genuine True HEPA and carbon filter. No inferior HEPA-type or carbon sheet filter as a substitution despite in a compressed 8.8 inches cylinder shape body. We have no trouble finding a place to fit the air cleaner in the bedroom, dormitory, or boardinghouse.

Another thing that makes Levoit Core 300 great is QuietKEAP technology. Using an internal shock pad that helps reduce noise, increase abrasion resistance, and extend the life of the motor. With QuietKEAP technology, the noise level is at a low 24 decibel to a high 50 decibel at max speed. It might not sound awfully impressive, but in real life, you can really feel the quietness coming from the device.

Here are the highlights of Levoit Core 300 air cleaner:

  • Dimension (W x H x D) - 8.7 x 14.2 x 8.7 in
  • Weight - 8.8 lb
  • Noise Level - 24 to 50 dB
  • Sleep Mode - Yes (Manual)
  • Filtration - Pre-Filter, True HEPA filter, Activated carbon filter (Optional Pet allergy filter, Toxin absorber filter, mold, and bacteria filter)

Inside Levoit Core 300 core, you will find a 3-stage Vortexair Technology that uses a cyclonic airflow pattern to speed up air circulation. Complimenting the strong airflow is a washable pre-filter that can help trap dust, lint, fiber, hair, and other large irritants you will find in a typical house. Next, the inner True-HEPA filter will trap 99.97% of fine particles down to 0.3 microns that manage to bypass the pre-filter. Finally, the Activated carbon filter will target smokes, fumes, and odors that can only be capture through chemical absorption. For those that are suffering from severe allergies, you can upgrade your carbon filter to either Pet allergy filter (for pet owners), Toxin absorber filter (for chemicals), mold, and bacteria filter (for high humidity areas). With a wide 219 square feet purifying coverage and 140+ cfm CADR, Levoit Core 300 is suitable for all types of bedrooms. We find it very useful for a studio or duplex home where you could cover more spaces with just one air cleaner.

Moving to usability, Levoit Core 300 is very easy to operate with a top touch control panel. Besides the standard 3 fan speed controls, there is sleep mode where the display light will be off while running at the quietest speed. Right next to it is the timer button that can be set to turn off the device between 2, 4, 6, 8 hours. On the other side of the controls, you have a filter reset button, display light off button, and child lock button. Display light off is a simple yet critical feature that ensures no glaring light will disturb your sleep. The child lock button is particularly useful if you placed Levoit Core 300 in a children's room and want to prevent them from meddling on the controls.

For the few drawbacks, understandably there is no autonomous mode or air quality indicator given the lack of a built-in sensor. The short filter lifespan also means you will have to change the cartridge more frequently than some models. Take nothing away from Levoit Core 300 capacity in providing you with a peaceful night sleep.

Sleeping can be a chore in today's society. In today's constant swiping and mindless scrolling in bed, you will need a good bedside air purifier that can guarantee you clean air while you lay on the bed. Levoit Core 300 may or may not affect your sleep quality, but it's good to know you will not be deprived of sleep due to bad air.

In short: A small bedroom HEPA air purifier with impressive specification at an entry-level price. One of the better choices if you don't mind the short 6 months lifespan.

If you need a powerful yet small air purifier that can be placed on the bedside table, Medify MA-15 H13 HEPA is the one. At only a short 15.5 inches in height and 9.7 inches in overall diameter, there is no shortage of options to place the air cleaner. The 6.6 pounds is not the lightest but still perfectly fine to carry around. Perfect for morning office desk and night bedtime use.

Comes in white, silver, and black, Medify MA-15 clean exterior is pleasing to the eyes without sacrificing functionality. The air inlet is located at the bottom and air outlet at the top surrounding the controls. Speaking of controls, there is the 3 adjustable fan speed and a filter change indicator reminding you to change the filter when necessary. There is also a child lock function to prevent the children from messing with the setting while you sleep and a timer that can be set to turn off the machine when you about to wake up.

Overall, Medify MA-15 is very well-built with no off-gassing or misalignment sighted. Besides all the usual AHAM, UL, and ozone-safe certifications, there is also a lifetime warranty in place that covers any manufacturing defects.

For such a low price, here is what you will get with Medify Air MA-15 :

  • Dimension (W x H x D) - 9.7 x 15.5 x 9.7 in
  • Weight - 6.6 lb
  • Noise Level - 35 to 51 dBA
  • Sleep Mode - Yes (Manual)
  • Filtration - 2x Pre-Filters, HEPA H13 filters, Activated Carbon Filters

As a bedroom air purifier, Medify MA-15 quiet 35 dBA noise output can ensure consistent clean air during sleep. Even at max 51 dBA white noise, it will not disturb your rest after a long day. You do have to turn the machine in the opposite direction of your bed to avoid the glaring indicator light when all lights are off. Power usage is only 18 wattage so you can safely leave it on the whole day even after you're awake.

When dirty air is drawn inside the air purifier, the pre-filter will block out large particles like dust, hair, fibers, lint and protect the inner HEPA filter from being damaged. The medical-grade H13 HEPA filter will trap 99.9% of irritants as small as 0.1 microns like mold, pollen, dust mite, bacteria, and viruses. For smoke particles and odors, you have the carbon filter with carbon pellets standing by to deal with cooking smells, cigarette smoke, musty mold, and pet odors that would otherwise stink up your bedroom.

At full speed, Medify MA-15 air purifier can cover up to 330 square feet at 2 air changes per hour. Suitable for most bedroom sizes including dorms and hotels. Clean air delivery rate or CADR is at a decent 150 cfm for dust, pollen, and smoke. Not bad given the air purifier compact size and price point.

Let's talk about the few cons. There is no built-in sensor, air quality indicator, auto mode, or Sleep mode. Big bummer given this is supposed to be a bedroom air purifier after all. The filter set is also expensive to maintain with only 2500 hours or 3-4 months of lifespan. Under a bad air environment, the filter cost could go up to 140 dollars annually. Best for an asthmatic person that needs absolute clean air but not so great for your wallet. There are other more cost-effective bed air purifiers out there that can help you sleep soundly every night.

In short: A compact, powerful, and affordable air purifier that packs a punch. The included medical-grade H13 HEPA filter is the perfect icing on the cake. The only letdown is probably the high filter cost that all are willing to partake.

Where To Place An Air Purifier In The Bedroom?

For optimal performance, an air purifier should be placed next to your bed or by the corner with 1-2 feet of gap between the wall. This will effectively shield the sleeper from any incoming germ, dust, mold, or pet dander. Placing it at the center would work as well for maximum bedroom coverage. The only concern is the device could be an obstruction as one might trip over the cable. You can learn more about the art of air purifier placement here.

Do Air Purifiers Help You Sleep Better?

An air purifier can help you achieve deep sleep by trapping all airborne irritants in the bedroom. Without the high concentration irritants triggering an allergy, you will not have to deal with a dry throat, sinus, or cough the next morning. An air cleaner should not be turned off because airborne contaminants will slowly build up without you realizing it. If you are worried about the fan noise or glaring LED light, just set the fan speed to low or switch it to Auto/ Sleep mode.

Is It Safe To Leave An Air Purifier On All Night?

You can leave an air purifier on all night as it is designed to do so. By leaving an air purifier running 24/7, there are fewer airborne pollutants in the room. You will be breathing better, sleep better, and there is less chance of your allergies flaring up. Just make sure you pick a bedroom-compatible air purifier that is quiet and energy-efficient.

Long Term Benefits Of Sleep

A night of good quality sleep is just as important as regular exercise and a healthy diet.

How Can I Improve The Air Quality In My Bedroom?

Air quality in the bedroom is way worse than the outdoor air (5 times worse to be exact). Here are a few tips that will help you achieve clean air in no time.

  1. Get a quiet bedroom air purifier with HEPA filter. The quickest way to filter out all indoor air pollutants.
  2. Keep your room well-ventilated by opening more windows and doors. This only works if the outdoor air quality is better than indoor air.
  3. Regularly maintain your air-con and HVAC system to ensure there is no dust piling up that block the airflow circulation.
  4. Vacuum, vacuum, vacuum. Dust and other settled contaminants are one of the biggest contributors to airborne particles.
  5. Dust mites often linger in the fabric, upholstery and can easily become airborne when being disturbed. Wash your bedsheets, cushion, and clothes to prevent dust mites from spreading.
  6. Get air-filtering houseplants like English ivy, snake plant, or bamboo palm. It may not be as effective as an air cleaner, it can still clean your air from CO and other pollutions.
  7. Beeswax candles, salt lamps, and essential oil are good remedies for cleaner air. They release negative ions that will bring down positive ions airborne pollutants. Your room will be filled with fragrance smells that can also alleviate asthma symptoms.

What To Look For When Choosing A Bedroom Air Purifier?

Not all air cleaners are designed for bedroom use. According to the American Psychological Association (APA), 60% of adults have difficulty sleeping every week. Picking the right model is critical as it will be a long-term investment for your well-being. You will sleep soundly at night and well-rested the next day. To guide you through the buying journey, here are the basic terminology and features you will need to know.

  1. Cost of ownership - $150-300 is our target range with annual filter cost less than $100. Some models will cost more but in return, you will get better features and performance.
  2. Room size - United States bedroom size on average is between 120 and 150 square feet. We recommend getting an air cleaner with at least 200 sq. ft. coverage at 2 air changes per hour.
  3. Pre-filter – The most common filter in every air cleaning device. This reusable filter is designed to block out dust, hair, and other large particles while prolonging the lifespan of other filters.
  4. HEPA filter - The must-have in our book. A true HEPA filter will need to fulfill the regulations set by the United States Department of Energy (DOE) to have at least 99.97% efficiency in capturing particles as small as 0.3 microns. The bedroom air purifying device chosen here must be equipped with equivalent or better filters. No settling for an inferior HEPA-type filter.
  5. HEPA-type Filter – A lower-grade version of the True HEPA filter that captures 99% particles as small as 2 microns. Does not meet the U.S. DOE standard.
  6. Carbon filter - AKA deodorization or charcoal filter that adsorb toxic fumes, gases, and odors. If you have an issue with smoke and odor in your bedroom, a carbon filter is a must.
  7. Noise Output - Very important as the fan noise can be a big distraction to your sleep. Choose a model that will output low-frequency white noise.
  8. Branding reputation - Since we will be running the air cleaner 24x7, reliability is critical. A model with a long period of warranty and good after-service support is appreciated.
