We love being able to provide a service that helps keep our community healthy.

Our filters are 100% American-made and come with a subscription service to simplify the replacement process.

MERV, or Minimum Efficiency Reporting Value, is a scale that rates the ability of filters to trap particles, with higher numbers capturing smaller microns. MERV 8 filters are perfect for standard protection, MERV 11 for superior protection, and MERV 13 for optimal protection. The Odor Eliminator filters with MERV 8 quality also inhibit unpleasant smells.

When choosing the right filter size, it's important to consider the nominal size (rounded to the nearest inch) and the actual size (the precise measurement) of your current filter. Measuring the width, length, and depth of your existing filter can help you find the perfect replacement.

Changing your air filter regularly is crucial for maintaining a healthy lifestyle and keeping your HVAC system running efficiently. We generally recommend replacing the filter every 90 days, but this may vary based on factors like pets, allergies, and the number of occupants in your home.

At Filterbuy, we are committed to providing better air for all. We believe everyone deserves access to clean indoor air, and we work tirelessly to ensure you and your community can breathe freely. Our high-quality, American-made filters and subscription service make it easy to keep your home or business well-protected.
