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 without accounting for bed, wardrobe, or table lamps 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 size, 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 maintains the fan speed to low yet 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.

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 be 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 - Ideally $150-300 is our target range with an annual filter cost of 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 the HEPA filter.
  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) with 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 adsorbs 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 - Under 30 dB would be the ideal benchmark as a loud 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 for longevity. A model with a long period of warranty and good after-service support is always appreciated.

Levoit might not be the biggest household name that everyone is familiar with, they do release some exceptional value models that can be used during bedtime. 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 house in a compressed 8.8 inches cylinder shape body. The light 8.8 pounds weight also makes it very easy to move it around the house for those that depend on a single air purifier. We have no trouble finding a place to fit Levoit Core 300 air cleaner in the bedroom, dormitory, working space, or boardinghouse.

An affordable, small bedroom HEPA air purifier with impressive specifications for everyday use. One of the better choices if you don't mind the short 6 months lifespan.

Moving to usability, Levoit Core 300 is very easy to operate with a top touch control panel. Besides the standard 3 fan speed that varies in noise generation, there is the must-have sleep mode where the display light will be off while running at the quietest speed. Use this every night to enjoy a good night's sleep. Right next to it is the timer button that can be set to turn off the device between 2, 4, 6, 8 hours. You can set it right before you hit the sack or leave for work. 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 to 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.

Another thing that makes Levoit Core 300 great is the silent QuietKEAP technology. It uses 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 decibels to a high 50 decibels at max speed. It might not sound awfully impressive at max speed, but in real life, you can really feel the quietness coming from the device. No problem using Levoit Core 300 during nighttime when you're trying to catch up on sleep.

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, you will find a 3-stage Vortexair Technology that uses a cyclonic airflow pattern to speed up air circulation. At full speed, it will cover a good 219 square footage of air cleaning space at around 2 air changes per hour. AHAM verified Clean air delivery rate is acceptable for bedroom use with dust CADR at 140 cfm, pollen CADR 145 cfm, and smoke CADR at 141 cfm. As long as you place Levoit Core 300 close to the pollutant's source, it will maintain your indoor air quality at a healthy level and prevent airborne allergens from triggering your allergies.

LEVOIT Core 300 HEPA Air Purifier Review

Complimenting the strong airflow is a washable pre-filter that traps dust, lint, fiber, hair, and other large irritants you will find in a typical house. Next, the inner True-HEPA filter traps 99.97% of fine particles and allergens 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 captured 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), or mold and bacteria filter (for high humidity areas). Again with the wide 219 square feet purifying coverage and 140+ cfm CADR, Levoit Core 300 is suitable for all types of bedrooms. Perfect for a small studio or duplex home where you could cover more spaces with just one air cleaner.

For the few drawbacks, understandably there is no autonomous mode or air quality indicator given the lack of a built-in sensor and low price tag. The small purifying range means Levoit Core 300 is only meant for bedside use in order to bring the best out of it. The short filter lifespan also means you will have to change the cartridge more frequently than some models. Thankfully the annual filter replacement cost is at a very accessible 20-40 dollars. Take nothing away from Levoit Core 300 capacity in providing you with a peaceful night's 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: An affordable, small bedroom HEPA air purifier with impressive specifications for everyday use. One of the better choices if you don't mind the short 6 months lifespan. ⚠️ Buy this if you want a budget HEPA air purifier for sleep.

Winix 5500-2 air purifier is always the first in our consideration list for many good reasons. It is well-priced, well-specced, and has a decent 53 to 226 cfm airflow output with a wide 360 square feet coverage that caters to a large bedroom. Supporting that is the impressive CADR at 243 cfm dust-free, 246 cfm pollen-free, and 232 cfm smoke-free.

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, it is still capable of room-to-room purifying by grabbing the back handle. With the strong airflow delivery rate, you can place it further away from the bed while still enjoying full-fledged clean air.

The conventional side air inlets and a back air outlet work well in Winix 5500-2 black housing setup. You can place it close to a wall or bed with just a few feet of gaps between them. Overall the build quality is good that will last longer than the modest 2 years warranty would suggest. You will enjoy many nights of good sleep with Winix 5500-2 by your side.

You can cycle the 4 fan speeds (Low, Medium, High, Turbo) or choose auto/ sleep mode via the mode button. The 1, 4, 8 hours timer can be set to turn off the machine accordingly. The center PlasmaWave mode activates/ deactivates Hydroxyls function. We highly recommend you leave it on to assist with the filtration yet without creating any harmful byproducts. The reset button is only used after you change to a brand new filter set and turn off the filter indicator light. Remote control is the cherry on the cake especially for an air purifier at this price point. You can manage the Winix 5500-2 at the comfort of your bed.

Winix 5500-2 Bedroom Air Purifier Review

Powered by the familiar 4-stage PlasmaWave filtration like most Winix models in the lineup, the initial pre-filter traps large particles like dust, lint, fiber, and hair while extending the HEPA filter lifespan. Very useful as bed dust mites and fibers will be stirred up every time we jump into the bed. The protected True HEPA filter will focus on removing 99.97% of airborne irritants down to 0.3 microns that are flowing above your sleep area. This includes pet dander, mold, pollen, germs that are notorious for triggering your allergies and lead to many sleepiness nights. Next, the deodorization AOC Carbon filter will effectively adsorb smoke and toxic gases like ammonia, radon, VOCs, CO, CO2. Very important for those sleeping in a poorly ventilated room. Finally, PlasmaWave technology would emit Hydroxyls to assist in dismantling the molecular structure of chemicals, germs, and odors. The final piece of the puzzle of Winix awesome filtration.

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. .

There are not many faults you can find here for a bedroom air cleaner. If you are being picky, the annual filter replacement cost can stack up quickly for the coming years. Levoit Core 300 filter set only costs half of what Winix 5500-2 is asking. The carbon filter is also not the quickest in removing odor but no big deal since the smell will be clear out when running throughout the night. The particle sensor will occasionally slow to detect nearby pollutants, but that could be partially due to a dirty sensor. Again, we are nitpicking at this point.

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 air purifier might be able to help. Without the harmful particulates pestering your sleep, you will breathe smoother and wake up feeling completely refreshed.

Thankfully you only have to do this every 12 to 24 months depending on the indoor air quality status and how frequently you use the air cleaner. Airflow output is a tad constraint and CADR is far from best for the premium price you paid. On the flip side, the annual filter replacement cost is very reasonable between 43 to 85 dollars for a 6-stage air cleaning system. If money is no objection, Rabbit Air MinusA2 would be the best air purifier for the bedroom. period. But at close to 600 dollars excluding the addons, it is very expensive and this could be the biggest deal-breaker.

At 16.8 inches in width, 18.3 inches in height, 9.6 inches in depth, and 12.3 pounds in weight, Coway Airmega AP-1512HH is not overly big but still can be cumbersome when placed in a small bedroom, dorm, or shared room. While it is still portable for multi-location air cleaning, the bulky size is unavoidable in order to fit in the full-size filters and a huge fan. Most people will place it inside the bedroom all day where they will spend the most time there. The official 3 years warranty reflects well on the quality and durability of the air purifier. We wish it comes with 5-years though like the more expensive Airmega 300 and 400 series. There is an updated version in white and Wi-Fi support, but we will leave that for now.

There are still more things we liked about Coway Airmega AP-1512HH. The low entry-level price and annual filter replacement cost under 50 dollars make it highly accessible.

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.

Not many drawbacks you will in Coway Airmega AP-1512HH for bedroom use. The "main" thing missing is the sleep mode that will lock the fan speed to the lowest and dim the indicator light. Fortunately, substitute auto mode is here to keep things in check. 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 and requires less care. 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, why not give Coway Airmega AP-1512HH Mighty a shot.

In short: One of the best air purifiers for bedroom with exceptional performance and price. The dated design is compensated with a True HEPA filter that works well with auto mode. ⚠️ Buy this as a budget alternative to Core 300 and don't mind the increase in size.

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. Since there is no sleep mode, we suggest you turn the air purifier facing outwards to reduce light glaring during the night. Power consumption will be based on the fan speed you are constantly in, but it will be within the energy-efficient bracket. Another thing that we liked about GermGuardian AC5250PT is the comprehensive 5 years manufacturer warranty.

GermGuardian AC5250PT Bedroom Air Purifier Review

There are always pros and cons with 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 that is poorly ventilated. The filter set also requires more frequent change between 6 to 9 months. Airflow output is adequate at best and there is no autonomous feature at all. Lastly, the 50 to 80 dollars filter replacement cost might be slightly pricey for someone that only needs a basic air cleaner for bedside use. If you are on a more budget-conscious side and do not have a domestic pet, Levoit Core 300, Medify Air MA-15 might be the smarter choice.

Nobody can live without sleep. Good quality sleep is crucial in preserving 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 powered by a 5-stage filtration system. Perfect for pet owners that have pets sleeping on their bed. ⚠️ Buy this if you want a tower air purifier and can settle with the tall tower form factor.
