The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20. Our MERV 8 Air Filters provide standard protection (90%) for almost any home or business, our MERV 11 Air Filters offer superior protection (95%) for homes or businesses with pets, smokers, or allergy sufferers, and our MERV 13 Air Filters provide optimal protection (98%) for larger homes or businesses and those who want the best possible filtration.

We also offer MERV 8 Air Filters with Activated Carbon, perfect for homes or businesses that want to inhibit unpleasant smells while maintaining reliable MERV 8 quality.

Choosing the correct filter size is important. The nominal size is a rounded number, while the actual size is the precise measurement. To find the right fit, measure your current filter and round up to the nearest inch.

Replacing your air filter regularly is crucial for maintaining a healthy lifestyle, as breathing dirty air can lead to asthma, allergies, and other respiratory issues. We generally recommend replacing your filter every 90 days, but this may vary based on factors like pet ownership, allergies, and the number of people in your home.

At Filterbuy, we believe that everyone deserves access to clean indoor air. Our commitment to quality, customization, and community investment sets us apart as we work to provide better air for all.
