Our air filters come in a variety of MERV ratings, each designed to address different needs. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate. MERV 11 filters are ideal for homes or businesses with factors like pets, smokers, and allergy sufferers. MERV 13 filters are perfect for larger homes or businesses and those who want the best possible filtration experience. We also offer MERV 8 filters with activated carbon to inhibit unpleasant smells.

Choosing the right filter size is important. The nominal size is a rounded number, while the actual size is the exact measurement. If your current filter does not have a dimension listed, use a tape measure to find the actual size, then round up to the nearest inch to find the corresponding nominal size.

Replacing your air filter regularly is crucial for maintaining a healthy lifestyle. Breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean.

Our filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system, as long as you choose the proper size. The number of filters you need will depend on the specific needs of your home or business, but our selection includes package quantities ranging from 1 to 12 filters.

Changing your air filter is a straightforward process. After finding the right size, turn off the power supply, remove the cover from your intake vent, take out the old filter, and insert the new one in the correct direction of air flow. Replace the cover and turn the power back on.
