At Filterbuy, we take pride in being a one-stop shop for all your air conditioner, furnace, or HVAC system filter replacements. We offer hundreds of custom sizes in a variety of filtration ratings to ensure you find the perfect fit, regardless of your specific needs. This helps us achieve our goal of providing you, your family, and your community access to clean indoor air that enables you to live and breathe freely.

Our products are unique because we offer premium features that provide an enhanced filtration experience. This includes a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures.

We solve the problem by giving customers the ability to simply purchase the exact filter size they need from the comfort of their homes. Our robust supply chain ensures that we can deliver these custom sizes quickly at no extra cost.

We love being able to provide a service that helps keep our community healthy. We offer a range of air filters, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell air filters, each with varying levels of filtration efficiency.

The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. MERV 8 air filters provide standard protection (90% of airborne particles), MERV 11 air filters offer superior protection (95%), and MERV 13 air filters deliver optimal protection (98%) for larger homes, businesses, and those who want the best filtration experience. We also offer MERV 8 air filters with activated carbon for odor elimination.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size reflects the filter's precise dimensions. Measuring your current air filter and rounding up to the nearest inch can help you find the right replacement.

Regular filter changes are 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 factors like pet ownership, allergies, and the number of people in your home.

Our air filters are universally compatible and 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 your specific situation, and we offer package quantities ranging from 1 to 12 filters to ensure you're covered.

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

At Filterbuy, we are committed to championing indoor air quality and providing access to clean, healthy 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 that enables us to swiftly fulfill diverse, custom orders across the country.

To simplify the filter replacement process, we offer a subscription service that ensures your filters arrive on time as requested, with a discounted rate for enrolled customers. As our company continues to grow, we remain true to our values by keeping our commitment to community investment and personal aid at every possible opportunity.
