Top Air Purifiers for Sleeping & Bedroom 2024

EPA estimates that 90% of our time is spent indoors (in addition to 2x to 5x more polluted air than outside). (If we're lucky) we spend at least eight hours in the bedroom each day. Because of this, people tend to opt for an air purifier for sleeping or at least an air purifier with sleep mode for their bedrooms. It is possible to place any air purifier in a bedroom, but not all of them are meant to be used as bedroom air cleaners. It will help if you keep these guidelines in mind when selecting the best air purifier for your bedroom. Among them are:

• Operates silently. No more than 60 decibels.
• True HEPA filters can capture even the smallest pollutants.
• Possibility of dimming lights.
• Controls on smartphones are preferred. Changing your air purifier's settings when you're tucked in is the last thing you want to do when you're in bed.

According to these criteria and specifications, such as coverage area, CADR rating, airflow, and filtration system, we will look at some of the best air purifiers for sleeping near your bed. The majority of them eliminate dust and other common allergens in bedrooms.

Best Features of Air Purifier for Sleeping

Filtration Systems

The best air purifier for better sleep has a filtration system that is capable of capturing air pollutants common to bedrooms. It is dust that causes most of the air pollution in bedrooms. If you want to remove dust, make sure your bedroom air purifier has a HEPA filter.

Dust particles smaller than 0.3 microns are captured by HEPA filters in bedrooms more than 99.97% of the time. HEPA filters and dust particles capture pollen, smoke particles, and other allergens that may interfere with your sleep.

Additionally, hair and unpleasant odors (for example, sweat) are more prevalent in the bedroom. The reasons are obvious: every day, we sleep for eight hours. The hair we lose during that time and all the sweat we produce stay in the bedroom. This is why you'll find two additional filters in the best bedroom air purifiers:

• The HEPA filter is protected from hair, pet dander, and dust.
• For sweat odors, activated carbon is used. A charcoal filter like this can remove gaseous pollutants inaccessible to mechanical filters.

CADR Rating

In order to determine how effective bedroom air purifiers are at removing three major air pollutants, the CADR rating is vital. Here are the three pollutants:

• The bedroom is dusty. Particularly, dust particles ranging from 0.09 to 1.0 m are commonly found in sleeping areas.
• Bedroom pollen.
• There is smoke in the bedroom.

AHAM independently tests air purifiers to determine their CADR ratings. Most air purifiers have a CADR rating of about 200. Learn all there is about the difference between air purifiers and humidifiers on our site and how a CADR rating works.
