How often should I change my air purifier filter?

To maintain optimal air quality and device performance, it's recommended to change your air purifier filter according to the manufacturer's guidelines—typically every 1-2 years. The exact timing may depend on usage and environment. For specific replacement intervals and expert tips, be sure to review the Air Purifier Buying Guide.

What types of air purifier filters are available and what do they remove?

Air purifier filters commonly include HEPA filters, which are ideal for removing dust, pollen, pet dander, bacteria, and mold spores. Some models also feature activated carbon filters that absorb odors and chemical pollutants. For a detailed overview of filter types and what they address, see the Air Purifier Buying Guide.

Can a new air purifier filter help with allergies or asthma?

Yes, regularly replacing your air purifier filter—especially with a unit containing a True HEPA filter—can significantly help reduce allergens like pollen, dust mites, and pet dander. Those with allergies or asthma often benefit from HEPA filtration. Learn more about the benefits by exploring the Air Purifier Buying Guide.

Do I need a carbon filter to eliminate odors from my home?

HEPA filters alone are not designed to remove odors. If you want to eliminate household odors, look for air purifiers that use activated carbon filters. These are effective against smells and gaseous pollutants. Read about choosing the best filter combination in the Air Purifier Buying Guide.

Find Air Purifier Filters at Abt

With 90 percent of our time spent indoors, creating an environment where the air is clean and safe is more important now than ever before. Abt Electronics offers official replacement air purifier filters from the companies that made your device. This ensures a perfect fit, and filtration as good as the day it was new. Dirty or clogged filters can lead to increased energy consumption, loud operation, and most importantly, poor filtration and dirty air. An air purifier can remove many common pollutants from your indoor air, starting with dust and fine particles. Units with True HEPA filters can remove smoke, pollen, pet dander, bacteria, mold spores, and dust mites. In models that also include carbon filters, even gaseous pollutants can be captured. If you have allergies, asthma, or increased risk factors for illness, HEPA air purifiers are your best option. Studies have shown that the air indoors can be much dirtier than the air outdoors due to a variety of factors. They include the usual suspects such as dust, pet dander, and household chemicals, but also gases escaping from electronics and building materials.

HEPA filters by themselves are not designed to properly eliminate odors. This is why many air purifiers include some form of activated carbon filter in the design to absorb odors and chemicals. If you have pets or young children at home, an air purifier with activated carbon will remove odors from the air. Depending on the manufacturer, carbon filters can be built into the HEPA filter as one unit or sold separately. Maintain your air purifier with replacement air purifier filters from Abt. We carry HEPA filters and activated carbon layers, as well as filters that combine the two types. Replacing your air purifier filter regularly is essential to the proper functioning of your device. Change your filter according to the brand's recommended intervals to keep cleaning the air efficiently. Filter life will vary with what environment the purifier is used in, but generally, replacements are called for every 1-2 years.
