At Filterbuy, we take pride in 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 with access to clean indoor air, enabling you to live and breathe freely.

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

We give customers the ability to easily purchase the exact filter size they need from the comfort of their homes. 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 filters are available in various sizes, including 20x20x1, 16x25x1, 20x25x1, and 20x25x5 Honeywell Air Filters. The Minimum Efficiency Reporting Value (MERV) rating indicates the filters' ability to trap particles on a scale of 1-20, with 20 capturing the smallest microns.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. We recommend measuring your current air filter and rounding up to the nearest inch to find the corresponding nominal size.

We generally recommend replacing your air filter every 90 days to keep your system running efficiently and maintain clean air. However, this can vary based on factors like the number of pets, allergies, and the number of occupants in your home.
