Air Filter

Air filters are small, affordable components that play a vital role in keeping your heating and cooling systems running smoothly. They also help improve your indoor air quality by capturing dust, hair, and debris that circulate through your home. By filtering out these particles, air filters protect your HVAC system from damage and extend its lifespan.
Additionally, air filters can trap allergens, microorganisms, and other fine particles, making them even more important, especially as outdoor air quality worsens. We offer HVAC filters, furnace filters, air filters, and HEPA filters to meet a variety of needs and ensure optimal indoor air quality.
For optimal performance, it's recommended to replace your air filter every three months. If your filter gets dirty quickly, you can also change it once a month.
The nominal size of an air filter refers to its standard dimensions, while the actual size is the exact measurement of the filter, typically slightly smaller than the nominal size to ensure a proper fit. The actual size usually 0.2’’-0.5’’ smaller than the nominal size. Below is a table for reference. We also support OEM.
