We solve the problem of giving customers the ability to simply purchase the exact filter size they need from the comfort of their homes. Furthermore, 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. 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell air filters are just a few examples of the wide range of options we offer.

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 are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, providing 90% standard protection. For homes or businesses accounting for factors like pets, smokers, and allergy sufferers, our MERV 11 air filters offer 95% superior protection. Those seeking the best possible filtration experience can opt for our MERV 13 air filters, which provide 98% optimal protection, making them perfect for larger homes or businesses. Additionally, our MERV 8 air filters with activated carbon are perfect for inhibiting unpleasant smells while maintaining reliable MERV 8 quality.

When it comes to choosing the correct filter size, it's important to understand the difference between nominal and actual sizes. The nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. Measuring your current air filter and rounding up to the nearest inch can help you 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, though the frequency may vary based on factors such as pet ownership, allergies, and the number of occupants in your home.

At Filterbuy, we are committed to providing better air for all. We believe that everyone deserves to breathe clean, fresh air, which is why we work tirelessly to ensure that you, your family, and your community have access to the air filtration solutions you need. Our 100% American-made products, green frames, and subscription service make it easy to maintain a healthy indoor environment.
