6. Most Quiet Bedroom Air Purifier: Levoit Vista 200

Levoit Vista 200 Air Purifier review

The Levoit Vista 200 is a compact air purifier for bedrooms at night.

It is made of a single-cylinder that draws in air from all sides, providing 360-degree ventilation. This allows for more efficacy.

It has several great features to make it one of the best bedrooms:

  • Sleep Mode Indicator and Button: You will notice a green light on the button when sleep mode is on. To turn it off, push the button again.
  • Timer Button and Indicators: By pressing this button, you program the air purifier to run for a specified time. That is 2 hours, 4 hours, or 8 hours if you like. When the air purifier’s set time runs out, it automatically shuts off. This indication makes it easy to tell which timer setting is currently in use.
  • Night Light Button: To help you relax and sleep better, you may switch on the ambient light by pressing this button. To turn it off, press it one more.
  • Display Off Button: If you are sensitive to light, push this button to turn off the touch panel’s LEDs.

Besides these cool features, this small air purifier has a 3-stage filtration system and can capture 99.97% of particles 0.3 microns in size.

Unfortunately, it is not very powerful, and with a CADR rating of 40 CFM, it can clean only 60 sq. ft. of small rooms 5x per hour.


  • Small and light air purifier.
  • Design that is both cool and elegant.
  • The touch screen is responsive and works well.
  • If needed, the product’s lights can be turned off.
  • The timer is very functional.


  • It has the texture of a fragile, plastic-like substance.
  • It covers a very small area


7. Renpho AP-089 Air Purifier for Larger Bedrooms

Renpho AP-089 Air Purifier for Larger Bedrooms

Allergists have consistently advocated RENPHO air purifiers and with good cause.

This air purifier for big rooms cleans up to 480 square feet 5x per hour without significant noise. The technology is twice as silent, even at top speed, as its main rivals.

In addition, the RENPHO smart features an H13 HEPA filter, which promises to catch 99 percent of airborne pollutants down to 0.3 microns, much like other high-quality air purifiers.

This, along with the device’s Laser Smart Import Sensor, which detects airborne particles as small as 0.3 microns, efficiently purifies your air of dust, smoke, allergies, and odor.

The air purifier is also designed with no cost spared. The various color lights on the Air Quality Indicator always represent the real-time purity of the room’s air in an easy-to-read display, saving you time and money on electricity.

This is a must-have item, mainly when it’s on sale. Air quality monitoring is unheard of at this pricing range, but you don’t get internet. It is unnecessary to manage it with a phone or an app since it monitors air. Put it on autopilot and leave it running all the time.

Despite high airflow, its CADR rating is much lower – 176 CFM. So, it means filtration is not as efficient as it could be. This is one of the reasons why we couldn’t rate it higher.


  • Air monitoring is automatic.
  • Colored light flashes at the top to indicate air quality.
  • The controls are simple to use and responsive to touch.
  • The touch controls include a child lock.
  • It seems to be effective in filtering air and odors.


Bedroom Air Purifier Buying Guide

According to the American Psychological Association (APA), 60% of people have sleep problems at least once a week. Mostly that’s due to the bad air. And here is when an air purifier can help you.

Not all air purifiers are suitable for use in the bedroom. Therefore, choosing the appropriate model is essential because it’ll be a long-term investment in your health.

You’ll get a good night’s sleep and wake up feeling refreshed.

Fundamental Terms And Features To Consider When Searching For a Bedroom Air Purifier

Noise Output

This is critical since fan noise may be a major sleep disruptor. Most air purifiers have severe fan speeds; you can switch to lower at night.

Usually, the lowest fan speeds are quiet and like white background noise. All air purifiers in this top have the very quiet lowest fan speeds.


The typical bedroom size in the United States is between 120 and 150 square feet. Therefore, we recommend investing in an air cleaner covering 200 square feet, providing 4-5 air changes each hour.

In our top, we calculated coverage by 5x air change per hour. So you can easily compare them. If your bedroom is larger, please check these air purifiers.


A small air purifier doesn’t mean it is weak. AirDoctor 2000 proves that even a small air purifier can show superb efficiency.

If your bedroom air is really bad, you have bad odors, or maybe a pet in your bedroom, go for the top 3 air purifiers from our list.


For the bedroom, it is important to have a chance to turn off the lights. Many air purifiers have bright lights which can’t be dimmed.

So check if the air purifier can dim lights or turn them off.


As bedrooms are usually not large, you need a small air purifier so it doesn’t take up much space. All air purifiers in our list are small and must fit in any size bedroom.


What is the Best Bedroom Air Purifier?

The AirDoctor 2000 is the finest air purifier for a bedroom. It has a high-quality UltraHEPA filter, superb user features, and a 244-square-foot coverage area (5x hour), making it perfect for most bedrooms.

It is also quiet, has the option to dim lights, and consumes low energy using the lowest fan speed.

Do air purifiers work in bedrooms?

The simple answer is yes, but an air purifier is unlikely to remove or neutralize all of your home’s irritating particles.

Numerous particles may settle on soft and hard surfaces, such as furniture, bedding, carpets, and walls.

Is it wrong to sleep next to an air purifier?

Regarding air purifiers, using one while sleeping is similar to using one while awake. Ensure the cleaner isn’t blowing straight into your face if you have dry skin sensitivity.

Otherwise, an air purifier circulates the same air as a fan while users sleep – but cleaner.

Should I better turn off my air purifier at night?

Keep your bedroom air cleaner on to ensure you breathe clean, filtered air. When the air purifier is switched off, hazardous airborne pollutants, including dust, pet dander, mold, pollen, germs, and viruses, slowly return over 2 to 4 hours.

Besides, you’re recommended to leave an air purifier on all night. The longer an air purifier cycles the air at night, the cleaner the air in the room will become.

What is the Best Location for a Bedroom Air Purifier?

Place a bedroom air purifier around 6 to 10 feet from the head of your bed. It would help if you also directed the filtered airflow toward your head. This position will ensure you get the most out of inhaling filtered air.

Do Air Purifiers Help You Sleep Better?

Yes, air purifiers help you sleep better. They eliminate airborne particles that cause congestion and irritate your lungs at night, such as dust, dust mites, pollen, allergies, mold spores, smoke, and pet dander.

As a result, you can have a comfier sleep and wake feeling restored if you use an air purifier in your bedroom.

Why does my bedroom get so dusty?

This is because dust is more dense in a bedroom than everywhere else. Since the bedroom is smaller than the rest of the house, you have stuff. Hair, clothing/bedding fiber, dust mites, pet dander, and bacteria contribute to bedroom dust.

Another specific cause is blocked central ventilation or an air conditioner filter. When you work for lengthy periods, a filthy filter will distribute additional dust in the room rather than cleaning it.
