Why Bedroom Air Quality Matters

You spend close to a third of your life sleeping in your bedroom and breathing the air in it.

This makes the quality of that air, and the level of breathable allergens and contaminants in it, very important. Both to how well you sleep that night and to how well you feel the next day.

Research shows that poor indoor air quality in your bedroom can negatively affect your sleep and impact your mood and ability to concentrate the morning after.

It can even take a toll on your general health and immunity, leading to lower energy, regular respiratory problems and increasing your susceptibility to many diseases.

Buying an air purifier for your bedroom, and improving the quality of the air you breathe while you sleep, is a wise investment in your long term health and well-being.

Many people also notice an immediate difference the first morning they wake up after sleeping in purified air. The sore throat and itchy eyes that they thought was normal is gone and they feel much more refreshed.

Longer-term benefits include more energy, improved ability to concentrate, less allergies, fewer colds and flu, a lower risk of many serious diseases and an improvement in cardiovascular health markers.

It’s no overstatement to say a good bedroom air purifier can make a big difference in your life. Indoor air quality is that important to your overall health and wellness.

Best HEPA Air Filter for Bedrooms Under $100 — Levoit Core 300 Air Purifier Review

Core 300 Levoit Air FilterLevoit are a respected company with a reputation for high-quality air cleaners and have made many best-selling models over the years.

The brand new Core 300 True HEPA air cleaner, with customizable pollutant filters, is their latest and perhaps most impressive model yet.

Using an advanced centrifugal fan with 360° intake and VortexAir design for stronger airflow, this Levoit air filter can refresh the air in a 215 ft² (20 m²) bedroom up to 5 times every hour.

In a smaller bedroom under 100 ft² this will be 10 times or more, which is highly beneficial for asthma and allergy sufferers. It would also greatly help combat intruding smoke or other ongoing air pollution entering your bedroom.

Despite its powerful air circulation and purification properties, the Levoit Core 300 is surprisingly low noise. Utilizing proprietary ‘QuietKEAP’ technology, this compact HEPA filter is nearly silent at just 24 dB in sleep mode with lights off.

The Core 300 is ozone free (can be sold in California) and is AHAM tested and certified for dust (140), pollen (145) and smoke (141). It also has an outstanding 230+ m³/hr CADR for its small size.

You can check the current price, read customer feedback and see home pictures of this impressive design here.

Customizable Pollutant Filters

The newest Levoit air purifier comes fitted with a H13 medical-grade True HEPA filter combined with activated carbon, nylon prefilter and airtight sealing.

This combination is highly effective at removing 99.97% of airborne dust, pollen, pet dander, mold toxins and dust mite allergens in your bedroom. It will also greatly reduce odors and volatile organic compounds.

Unusually, there are also 3 extra options available as replacement filters for the Core 300 – Mold Bacteria (with antibacterial filter), Pet Allergy (for odors, smells and pet allergens), and Toxin Absorber (for toxic gas air pollution and smoke).

All of these different options are for sale here. There’s a filter light on the Levoit to let you know when a replacement is needed, but if you’ve decided on the Core 300 then it makes sense to get an extra one.Levoit quiet HEPA air filter

Levoit Core 300 Pros and Cons


  • Very powerful and technologically advanced little air cleaner. AHAM tested and CADR of 230+ m³/hr is better than many larger and more expensive air filters.
  • 5 full air changes per hour in a 215 ft² room. Double that in a smaller bedroom 100 ft² or less. Great for asthma and allergy sufferers.
  • H13 medical-grade True HEPA/activated carbon filters with Mold Bacteria/Pet Allergy/Toxin Absorber replacement options.
  • Auto timer, 3 fan speeds and whisper-quiet at 24 dB in sleep mode with no distracting nightlights.
  • Small and compact at 8.7 x 14.2 inches and portable at 8.75 pounds. Can be positioned on a table to maximize space in a small bedroom.
  • Newest model from a well established and respected brand. 2 year warranty, according to Levoit replying to customers: “if you extend the original one-year by submitting a warranty card”.
  • Energy Star verified, ozone free, CARB certified for Californian sale, free shipping and excellent value.


  • No negative ionizer. Whilst older negative ion generators had issues with ozone, the latest technology does not. It’s a shame Californian regulation prevents more people from receiving negative ion benefits.
  • Levoit admit on their website that there may be a plastic smell when you first unwrap your Core 300. They recommend running it for a few hours in a well-ventilated room on high speed to remove this smell.

In Summary

There is very little to criticize with a review of the new Levoit Core 300 air purifier.

It’s an exceptionally well-designed and powerful HEPA air filter, yet virtually silent in sleep mode so great for bedroom air purification.

While it could work well in a lounge or living room, smaller rooms like bedrooms will give its best performance. Then again, being lightweight and portable you could even use it in both.

You can check the current price on Amazon here for the highly recommended Core 300.

Potentially big savings as this compact and almost silent HEPA air filter stacks up well against much more expensive competitors.

Quietest Air Purifier for Bedrooms — Hathaspace Smart HEPA Air Filter Review

Silent air purifierThe stylish Hathaspace Smart air cleaner could be used in any room in your home. It’s particularly good in the bedroom though as it’s the quietest air purifier reviewed here, at a virtually silent 18 decibels in sleep mode and no lights.

This almost noiseless air purifier for bedrooms uses 5 stage filtration, combining a True HEPA filter, activated carbon, antibacterial filter and nano cold catalyst to filter out 99.97 of airborne pollutants and allergens down to an incredibly small 0.3 microns.

There is also an optional negative ionizer, generating 10 million beneficial negative ions per second. These negatively charged ions attach to positively charged contaminants and prevent them from remaining airborne.

The Hathaspace has a smart air quality sensor on the front panel displaying the current indoor air quality. Set in auto mode it will adapt its fan speed in real time to match the current level of indoor air pollution.

This close to silent air purifier also comes with a remote control to operate it from your bedside and can be set on a 1 to 12 hour auto timer while you sleep.

Hathaspace say their whisper-quiet HEPA air cleaner will completely filter the air in a massive 350 ft² room twice in an hour.

You’d get much better performance for sleeping though with 4 air changes or more per hour in a small bedroom under 175 ft². Realistically, most of us sleep in much smaller bedrooms so the air change rate would be even higher.

The company also offers an impressive “60 day money-back warranty and 2 years of product replacement”, according to their listing and website.

Customer reviews are overwhelmingly positive and you can read them, see home pictures and check the current price here.

Hathaspace Smart Pros and Cons


  • 5 stage filtration with True HEPA, activated carbon, antibacterial filter, nano cold catalyst and optional ionizer.
  • Smart air quality monitor and auto mode that adapts to indoor air pollution in real time.
  • Customer reviews and feedback repeatedly mention how good this silent air purifier is for odors and smells.
  • Antibacterial filter for additional bacteria capture is an advantage over the other bedroom air cleaners in this review.
  • Big filters to trap more floating pollutants. This seems especially important for odors and toxic gases like VOCs. You can find replacement filters to buy here.
  • Super quiet air filter at only 18 dB on the low fan sleep mode. Also switches off all lights for undisturbed sleep.
  • Long warranty and available for free delivery in California and throughout the USA.


  • CADR is only listed at 160 m³/hr which is not as high as most of the other quiet HEPA air purifiers reviewed here. Better for small to medium bedrooms, not large rooms.
  • Product dimensions are 7 x 13.5 x 19.5 inches, making this a bigger unit than the ProBreeze or Levoit air purifier. Heavier as well at 12 pounds. Check you’ve got space for it in your bedroom.
  • Minuscule but detectable ozone output of 9 ppb. The EPA considers up to 50 ppb safe but this is something to be aware of for people with respiratory problems who may be extra sensitive to ozone.
  • Replacement filters are a bit more expensive than the Levoit or ProBreeze air cleaners.

In Summary

There’s much to like with the Hathaspace Smart silent air cleaner, particularly its whisper-quiet sleep mode and extra antibacterial and nano cold catalyst filters.

Despite being a bigger unit, it doesn’t have quite as many air changes as the Levoit Core 300 or Rabbit Air MinusA2 ahead, so will be best for smaller rooms, not large spaces.

Customer reviews are extremely positive though, especially regarding smoke and odor reduction, so if your bedroom has a smell that’s keeping you awake at night then the Hathaspace Smart air filter could be the solution.

Best Quality Air Purifier for Large Bedrooms — Rabbit Air MinusA2 Ultra Quiet Purifier Review

RabbitAir MinusA2 Ultra Quiet 780ABoth of the previous silent night air purifiers reviewed were very affordable.

The Ultra Quiet Rabbit Air MinusA2 is a step up for those looking for the ultimate bedroom air purifier and who don’t mind paying for something special.

It has a much higher recommended room coverage and number of air changes per hour than the Hathaspace and Levoit models. This makes the MinusA2 highly recommended for asthma and allergy sufferers.

Room Coverage and Air Filtering

The Rabbit Air MinusA2 Ultra Quiet HEPA air purifier has room coverage of a very large 700 ft² with 2 air changes per hour for the SPA-700A model and a massive 815 ft² and 2 air refreshes for the top of the range Rabbit Air MinusA2 SPA-780A.

Even at 4 air changes per hour, as recommended for asthma and allergy sufferers, the MinusA2 has a full 350 ft² of room coverage. Clearly this Rabbit Air model can filter a lot of indoor air pollution in larger spaces.

The smaller the room, the higher the number of air changes per hour goes, and the more effective the level of air purification and allergen removal is with this powerful air cleaner.

The Rabbit Air MinusA2 has a 6 stage filtering system for highly effective air purification:

  • Stage 1: A washable and permanent prefilter for larger allergens like dust and hair.
  • Stage 2: A medium filter for airborne particles larger than 1 micron, like pollen, mold and pet dander.
  • Stage 3: BioGS HEPA filter – Rabbit Air’s advanced and long-lasting HEPA filter captures 99.97% of airborne contaminants down to 0.3 microns.
  • Stage 4: Customizable filter – You can choose from Toxin Absorber, Odor Remover, Germ Defense and Pet Allergy, depending on your own particular allergen sensitivities.
  • Stage 5: Extra sized activated carbon filter made from high-efficiency granular activated charcoal.
  • Stage 6: Optional negative ionizer that complies with ozone safety requirements and is CARB tested and approved in California.

Design and Features

This Rabbit Air top of the range silent air filter has a unique big screen TV-like design that’s unlike any other HEPA air purifier I’ve ever reviewed.

It can sit on the floor, a table or be wall mounted (mounting kit included) and also comes in a variety of customizable panel designs, including famous artworks by Van Gogh and Monet.

You can see all of the different color and design options, including the new Wi-Fi enabled/app-controlled models, here on Amazon.

Full of advanced options and features, the MinusA2 has a remote control, adjustable fan speeds, auto and high pollen mode, indoor air quality indicator, odor sensor, optional ionizer and a light sensor to automatically transition to sleep mode when the lights go out.

At just 20 dB in sleep mode, the Ultra Quiet Rabbit Air MinusA2 is also one of the most silent bedroom air purifiers in this review, despite its much larger size and significant power.RabbitAir SPA-700A

Rabbit Air MinusA2 Pros and Cons


  • Advanced 6 stage air filtration. Big and wide filters capture more allergens and pollutants than smaller air cleaners and can be customized with special replacement filters.
  • Exceptionally large room coverage and high number of air changes per hour. Even in a huge 350 m² room, the Rabbit Air MinusA2 achieves 4 full air purification cycles per hour, often recommended for asthma and allergy sufferers.
  • Wall mountable to save space and many advanced features like air quality indicator, high pollen mode, odor sensor and auto sleep mode. Can be controlled by remote control or by phone app with the Wi-Fi model.
  • Stylish design and recommended for larger houses and big modern apartments. Especially beneficial for those highly sensitive to indoor air pollution, like allergy and asthma sufferers.
  • Virtually silent for bedrooms at just 20 dB in sleep mode. Automatically dims and goes into sleep mode when you switch off lights in the room, becoming one of the quietest air purifiers on the market.
  • Top-quality components, long-lasting brushless direct-current motor and excellent 5-year warranty, according to RabbitAir.


  • Much higher price point than any other quiet air purifier reviewed here. This is a premium air cleaner with an investment to match. That said, the MinusA2 outperforms many higher priced competitors in air changes per hour and room size coverage.
  • This is a big bedroom HEPA air filter at 10.7 x 24.2 x 24.5 inches and heavy at 23.9 pounds. Similar in size and weight to a mid-range big screen TV.
  • Replacement filters are not cheap but do last up to 2 years. That’s 4 times as long as regular filters so it does even out over the years. You can find them here in the Germ Defense, Odor Remover, Pet Allergy and Toxin Absorber options.

In Summary

Most small bedrooms will do just fine with the Hathaspace or Levoit air purifier previously reviewed.

However, if you want much more air purification for a larger bedroom, or need it because you or a family member suffers from asthma, regular allergies and other breathing problems, then consider investing in the superior Rabbit Air Ultra Quiet MinusA2.

With advanced air cleaning technologies and a 5-year warranty, this high-quality air cleaner for bedrooms will give you many years of peaceful sleep and healthier breathing.
