Best Air Purifier For Bedrooms – Our Top 6

air purifier for bedroom

We spend 8 hours or more every day in the bedroom. So it only makes sense that you should keep the air fresh and clean in that room. How can you find the best air purifier for bedrooms that is small, quiet, and allergy or asthma-friendly?

It’s not easy finding the best air purifier for bedrooms since they come in different sizes and models. If you sleep in a room with poor air quality you will not have quality sleep. This is a problem especially if you suffer from allergies. It gets harder to sleep if you have a stuffy nose or congestion. You could also have trouble sleeping if you live in a town or city with lots of pollutants in the air. This could also lead to sleeping disorders like sleep apnea.

That’s why you need an air purifier that keeps your air clean and fresh by removing all the harmful air pollutants like dust, pollen, pet allergens, odors, smoke, and fumes. These devices are an important part of your bedroom.

Here are some of the definitions and terminologies you will come across on your quest to find the best air purifier for bedrooms.


This is an important feature in air purifiers that use HEPA filters. A pre-filter helps to trap the large particles, pet dander, and hair. Overall, they help to improve the efficiency and life of the main filter. Most of pre-filters can be washed and reused for a long time.

True HEPA filter

This is a high-quality air filter that you will usually find in the best air purifiers. This filter comes with strict regulation guidelines set by the Department of Energy in the U.S. It captures all the particles even the microspores in the air. A true HEPA filter should be replaced every 6 months to a year. You can get the replacement either from the manufacturer or online stores.

Activated charcoal or carbon filter

This filter absorbs and neutralizes all the small particles, smoke, odors, gases, VOCs, chemical, cooking odor, pet odors, and fumes that pass through the HEPA filter.


This filter emits negative ions in the air. Since particles like dust, allergens, and bacteria have a positive charge, the negative ions bond with them. This causes the contaminants to become too heavy to stay in the air. These fallen particles are then collected by the electrostatic collection plates that can be washed and reused.

UVC light

Ultraviolet light in UVC is a powerful form of radiation that kills all microorganisms in the air, but is harmless to humans.


A highly reactive molecule that is known to kill bacteria, viruses, and remove odors. However, it uses chemicals to kill organic materials, which can be very harmful to your health. If exposed to certain levels of ozone it can cause throat irritation, chest pains, coughing, shortness of breath, and problems with your lungs.

BioGS HEPA filter

This is an advanced version of the true HEPA filter.It’s designed specifically to reduce the build-up of particles on the main true HEPA filter and help to prolong its life. If well maintained, this filter can last for about 18 months to 3 years.

How To Choose The Best Air Purifier For Bedrooms

Here are some important factors to keep in mind.

Room size

The size of your bedroom is a very important factor. The Clean Air Delivery Rate (CADR) isn’t the best way of determining how much air an air purifier can clean in a room. It just gives you a rough guide on the amount of airflow from the device. If you have a large bedroom, using a small air purifier with a low CADR will not purify the air quickly enough to affect its quality.


Many pollutants can be found in your bedroom. These include dust mites and their feces, mold spores, pet dander, tobacco smoke particles, or pollen that you’re likely to inhale when you’re asleep. There may also be gaseous pollutants like volatile organic compounds (VOCs) from household chemicals, mattresses, cigarette smoke, or carpets. However, if you have allergies, for example, from one type of pollutant, then you can get an air purifier that will take care of that type of pollutant.

Noise from the air purifier

Some people would like a quiet air purifier. Others like to sleep with white noise coming from the air purifier’s fan when it’s turned on. In this case, you can use the CADR as a rough guide. Air purifiers with a high CADR are larger with powerful and louder fans. Check online user comments to help you understand how loud a particular air purifier is. The noise that air purifiers make when using the fans means they’re more effective in cleaning more air in your bedroom. It’s not advisable to get air purifiers that operate silently because they generate ozone that is harmful to your health.
