Understanding filter measurements is crucial. The nominal size is a rounded number, typically in a larger font (e.g., 16 x 20 x 1), while the actual size is the filter's precise dimensions, often in a smaller font (e.g., 15.50 x 19.50 x 0.75). If your current filter doesn't have dimensions listed, use a tape measure to record the width, length, and depth, then round up to the nearest inch to find the corresponding nominal size.

Regular filter replacement is essential for maintaining a healthy lifestyle. Breathing dirty air can lead to the development of asthma, allergies, and other respiratory issues. Additionally, old filters can cause system defects, resulting in unwanted expenses through energy costs and repairs. We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean, though this may vary based on factors such as pet ownership, allergies, and the number of people in your home.

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. If you see a specific brand name on a listing, ensure it matches your unit model.

The number of air filters you need depends on your specific needs, such as the number of vents in your home. Our selection includes package quantities ranging from 1 to 12 filters, so we've got you covered.

Changing your air filter is a straightforward process. First, turn off the power supply and remove the cover from your intake vent. Then, simply insert the new filter, matching the direction of air flow, replace the cover, and turn the power back on.

At Filterbuy, we are committed to championing indoor air quality. We believe everyone deserves to breathe clean air, free of allergens and pollutants. Our green-framed filters, constructed with high-quality materials, symbolize the peace of mind that comes from knowing your home or business is properly cared for. As a proudly American-made company, we manufacture our products across the United States, enabling us to swiftly fulfill diverse, custom orders.
