This helps us achieve our goal of providing you, your family, and your community with access to clean indoor air, enabling you to live and breathe freely.

We solve the problem of allowing customers to conveniently purchase the exact filter size they need from the comfort of their homes. Moreover, our robust supply chain ensures 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 range includes 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell air filters, among others.

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. Our MERV 8 air filters offer standard protection (90% of airborne particles), MERV 11 air filters provide superior protection (95%), and MERV 13 air filters deliver optimal protection (98%), catering to various needs.

We also offer MERV 8 air filters with activated carbon for odor elimination (90% of airborne particles). Our filters are compatible with a wide range of systems and come in convenient 4-packs.

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

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

At Filterbuy, we are committed to championing indoor air quality and ensuring everyone has access to clean air. Our green-framed filters, made with high-quality materials in the USA, symbolize the peace of mind that comes with knowing your home or business is being properly cared for.

Our subscription service simplifies the filter replacement process, and we take pride in our community investments and personal aid initiatives. With nearly 70 years of experience, we strive to provide better air for all.
