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 can find the perfect fit for your specific needs. This allows us to provide you, your family, and your community with access to clean indoor air, enabling you to live and breathe freely.

What sets our products apart is the premium features they offer. Our pleated, electrostatic design captures more particles, and our reinforced beverage board frames can withstand extreme temperatures. By allowing customers to easily purchase the exact filter size they need from the comfort of their homes, and with our robust supply chain, 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. Our product offerings include 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell air filters, available in various MERV ratings.

A MERV (Minimum Efficiency Reporting Value) rating measures a filter's ability to trap particles on a scale of 1-20, with 20 capturing the smallest microns. Our MERV 8 filters offer standard protection (90% of airborne particles), MERV 11 filters provide superior protection (95%), and MERV 13 filters deliver optimal protection (98%), catering to different needs, from basic home requirements to those with pets, smokers, or allergy sufferers.

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

Choosing the right filter size is crucial. The nominal size is a rounded number, while the actual size reflects the filter's precise dimensions. To find the correct fit, measure your current filter and round up to the nearest inch.

Replacing air filters regularly is essential for maintaining a healthy lifestyle, as dirty air can lead to respiratory issues. We generally recommend changing the filter every 90 days, but this may vary based on factors like pet ownership, allergies, and household size.

At Filterbuy, we are committed to providing better air for all. We believe that everyone deserves to breathe clean, allergen-free air, which is why we work tirelessly to ensure our customers have access to high-quality, custom-sized air filters. Our new green frames symbolize the peace of mind that comes with knowing your indoor air is being properly cared for.

From our family-owned beginnings in 1958 to our nationwide manufacturing network today, we take pride in our 100% American-made products. We also offer a subscription service to simplify the filter replacement process, providing discounts and ensuring timely deliveries.

As we continue to expand our reach, we remain true to our values, investing in our communities and providing personal aid whenever possible. Filterbuy is dedicated to championing indoor air quality, one breath at a time.
