Air Purifier Filters & Replacements - HEPA Filters

The most effective way to remove the highest percentage of harmful particles from the air, is with a HEPA filter for your air purifier. They are an ideal way to trap pollutants and allergens and improve the quality of air in your home or business. HEPA filters are especially beneficial for anyone with respiratory health issues or sensitivities. HEPA air purifier filters trap 99.97% of airborne particles,  even particles as small as .03 microns.

The term HEPA stands for High-Efficiency Particulate Air. HEPA air filters meet HEPA air quality standards. They trap a variety of harmful agents in the air, ensuring you can breathe better.

Air purifier replacement filters should be changed every 6 to 12 months. If it's a carbon filter that eliminates odors and gases, change it every 3 to 6 months. 

Different brands of replacement air purifier filters vary in size, shape, and type for each air purifier model. They are not universally interchangeable. Each air purifier has specific dimensions to ensure the filter fits properly and has proper airflow. Using the wrong air purifier filter can reduce your purifier’s ability to clean the air. Use the specific filter that matches your air purifier to ensure it performs properly. 

There isn’t any difference between a HEPA filter and a true HEPA replacement filter.  The term true HEPA air purifier filter is a marketing term designed to promote HEPA filters. They both have the same superior filtration capabilities.

The size of the particles you need to eliminate, and the kind of air purifier filters you use, will determine how well they work, and if they are able to remove viruses and bacteria. Viruses aren’t always captured by HEPA Filters, but they can catch larger airborne droplets carrying viruses. Carbon filters don’t trap viruses or bacteria, but they do work for smoke, fumes, gas molecules, and VOCs. When combined with social distancing, handwashing, and adequate ventilation, air purifiers reduce airborne pathogens, but they don’t completely protect you from all viruses. 

Activated carbon air filters absorb gases and smells caused by pets, smoke, cooking, and volatile organic compounds. Some air purifiers have multi-stage filtration that uses both carbon and HEPA filters. The air filter you use and the size of your space determine how well carbon filters will eliminate smoke and odors. 

Custom HEPA filters are made for air purifiers that don’t use standard size HEPA filters because they don’t fit. Custom HEPA filters are often used in medical facilities or industrial settings, or when there is a need to filter specific contaminants. They’re also used when an air purification system is configured differently. They sometimes have unique dimensions, or an unusual shape to fit in a specific location. 

An inspection will show if an air purifier filter is clogged with dirt and debris and needs to be replaced. It often looks gray or black and may have reduced airflow. It could be making loud noises. If you smell odors that are lingering in the air despite your air purifier running, the filter probably needs to be replaced. Some purifiers have indicator lights that show when filters for air purifiers need replacing. If you have an increase in your allergy symptoms, it might mean your filter isn't working to capture airborne allergens because the filter needs replacement. 

Some air purifier filters are washable and reusable but not all of them meet HEPA standards for capturing fine particles. When repeatedly washed, sometimes they lose their effectiveness in removing all particles. Some can be cost-effective since you don’t have to purchase more, but they also need to be properly maintained. Some of them don’t provide the high level of filtration that HEPA filters do. 

A generic air purifier filter probably won’t work as well to trap impurities for you as a brand name replacement does and may not fit correctly. A filter that doesn’t fit might capture fewer contaminants or damage your purifier. Measure your air filter so whichever filter you pick fits properly. Using a reputable brand may be preferable, especially if you or a family member has respiratory health conditions or allergies, because trusted brands are often more dependable.
