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.

8 Best Air Purifiers for Bedroom In 2022 (Small and Quiet Air Purifiers)

  • The Pricing Factor

Do you wish to have a total cost of ownership of $150-300, with an annual filter cost of less than $100? Then, try to review more items. Besides, some versions are more expensive, but they provide superior features and performance.

  • Reputation building

Because the air cleaner will be working 24 hours a day, 7 days a week, dependability is essential. Therefore, a model with an extended warranty duration and after-sales reliable service is preferred.

  • Coverage

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 and providing two air changes each hour.

  • Pre-filter

It’s the most common filter found in all air purifiers. This reusable filter is meant to keep dust, hair, and other big particles out of the air while also extending the life of existing filters.

Air Filter Types

Filters are also essential for keeping bigger particles out of your system, which may cause harm. As a result, you should always use the appropriate filter and replace it when it becomes clogged. The many kinds of filters for home HVAC systems are listed below.

  • Filters of Fiberglass

Fiberglass air filters are the cheapest kind of filter and are disposable. They put less pressure on your HVAC system when pulling in air and keep big particles out. However, they do not filter out dust and other tiny contaminating particles very well.

  • Filters with Pleated Pleasure

Cotton or polyester pleats are used in pleated air filters. They are somewhat more costly than fiberglass filters, but they better filter dust and other tiny particles, such as pollen, mold spores, and pet dander.

  • HEPA Filters

High-efficiency particulate air (HEPA) filters should be used if you or your family suffer from allergies or other respiratory issues. While they are more costly than fiberglass and pleated air purifiers, they are the most efficient in removing dust, pollen, mold, animal dander, viruses, germs, and other irritants from the air.

  • Filters that block UV light

Air cleaners, which may be integrated into your HVAC system, utilize UV filters. They are less effective at removing dust and other pollutants, but they are helpful if indoor air quality problems that an air cleaner can solve.

8 Best Air Purifiers for Bedroom In 2022 (Small and Quiet Air Purifiers)


What is the Best Bedroom Air Purifier?

The Medify MA-25 is the finest air purifier for a bedroom. It has a high-quality HEPA filter, user features, and a 500-square-foot coverage area, making it perfect for any size bedroom.

The tempered glass panel, 3 fan speeds, 8-hour timer, night mode, and child lock are the most noticeable characteristics of strong air filtration.

The Medify MA-25 is the best offer on a decent bedroom air purifier with excellent efficiency and a reasonable price.

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. This is because 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?

When it comes to air purifiers, using one while sleeping is similar to using one while awake. Ensure the cleanser 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 that you are breathing 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.

What is the Best Location for a Bedroom Air Purifier?

One should 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 that you get the most out of inhaling filtered air.

Do Air Purifiers Help You Sleep Better?

Ideal purifiers can help users sleep better. They do so by eliminating airborne particles that cause congestion and irritate your lungs at night, such as dust, 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.

Is it OK to Leave an Air Purifier on All Night?

That’s perfect. 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. To enhance their efficiency, air purifiers are intended to work 24 hours a day, seven days a week.

Do air purifiers purify the whole room?

As the name indicates, Whole-home air-purifiers assist in purifying the air in the whole home rather than just one or two rooms. These systems cast a broader net, which might help your family avoid respiratory irritants by filtering out indoor air pollution.

In contrast to whole-home air cleaners, room air purifiers clean the air in one or two rooms rather than whole residences. Like whole-home air purifiers, room air purifiers are generally programmable. As a result, they may filter out indoor air pollution, preventing asthma, allergies, and respiratory irritants in your household.

Why does my bedroom get so dusty?

This is because dust has a higher density in a bedroom than everywhere else. Since the bedroom is smaller than the rest of the house, you have stuff lying around. 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.

Final Word

We hope you found our advice on selecting the finest air purifier for your generous bedroom.

As you’ve learned, various air filters for bedrooms may help you sleep better by removing undesirable particles.

You’re lucky if you picked one of the finest bedroom air purifiers listed here. Instead, you’d be receiving a high-quality HEPA air purifier to keep the air around you clean enough to breathe at night.

There are several sizes to select from, including a big, medium, and small air purifier for the bedroom that is silent to use.
