At Filterbuy, we pride ourselves on being a one-stop shop for all your air conditioner, furnace, or HVAC system filter replacements.

Our goal is to provide you, your family, and your community access to clean indoor air that enables you to live and breathe freely.

What makes our products unique? We offer premium features that provide an enhanced filtration experience via a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures.

What problem are we solving? We give customers the ability to simply purchase the exact filter size they need from the comfort of their homes. Plus, our robust supply chain ensures we can deliver these custom sizes quickly at no extra cost.

Why do we love what we do? We love being able to provide a service that helps keep our community healthy.

The Filterbuy difference starts with our measurement system. We use the Minimum Efficiency Reporting Value (MERV) scale to rate the ability of our filters to trap particles, with a range from 1-20 (smallest microns captured at 20).

Our MERV 8 air filters offer standard protection, perfect for almost any home or business that wants great indoor air quality at a reasonable rate. Our MERV 11 air filters provide superior protection, ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers. For optimal protection, our MERV 13 air filters are perfect for larger homes or businesses, and those who want the best possible filtration experience. We also offer MERV 8 air filters with activated carbon for odor elimination, perfect for homes or businesses that want to inhibit unpleasant smells with reliable MERV 8 quality.

When it comes to choosing the correct filter size, it's important to understand the difference between nominal and actual size. The nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. If your current air filter doesn't have dimensions listed, use a tape measure to find the actual size, then round up to the nearest inch for the nominal size.

Regularly changing your air filter is crucial to maintain a healthy lifestyle, as breathing dirty air can lead to respiratory issues. We generally recommend replacing your filter every 90 days to keep your system running efficiently and air clean, though this may vary based on factors like pet ownership, allergies, and the number of occupants.

At Filterbuy, we're committed to providing better air for all. We're proud to be an American-made company, manufacturing our filters in facilities across the country. Our new, green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for. And with our subscription service, we make sure your filters arrive on time, simplifying the process.
