MERV 8 air filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, capturing 90% of airborne particles. MERV 11 air filters are suitable for homes or businesses with factors like pets, smokers, and allergy sufferers, capturing 95% of airborne particles. MERV 13 air filters are ideal for larger homes or businesses and those who want the best possible filtration experience, capturing 98% of airborne particles.

We also offer MERV 8 air filters with activated carbon, which are perfect for homes or businesses that want to inhibit unpleasant smells while maintaining reliable MERV 8 quality.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size is the filter's precise dimensions. If your current filter doesn't have a size listed, measure the width, length, and depth to find the actual size, then round up to the nearest inch to find the corresponding nominal size.

Replacing your air filter is crucial for maintaining a healthy lifestyle, as breathing dirty air can lead to respiratory issues. We generally recommend replacing your filter every 90 days, but this may vary based on your specific needs.

Most of our air 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 depends on the number of vents in your home.

Changing your air filter is a simple process. Turn off the power supply, remove the cover from your intake vent, take out the old filter, and insert the new one, matching the direction of air flow. Then, replace the cover and turn the power back on.

At Filterbuy, we are committed to providing access to clean indoor air for all. Our new, green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for. We are proud to be an American-made company, with a robust manufacturing network across the country. We also offer a subscription service to simplify the process of regularly changing your air filters.
