The Minimum Efficiency Reporting Value (MERV) rating system measures the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. MERV 8 filters provide standard protection (90% of airborne particles), MERV 11 filters offer superior protection (95%), and MERV 13 filters provide optimal protection (98%).

We also offer MERV 8 filters with activated carbon, which are perfect for homes or businesses that want to inhibit 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 the nominal size (a rounded number) and the actual size (the precise measurement). To measure your air filter, use a tape measure to record the width, length, and depth, then round up to the nearest inch to find the corresponding nominal size.

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 such as the size of your home, the presence of pets, and the number of occupants.

At Filterbuy, we believe that everyone deserves access to clean indoor air. That's why we work tirelessly to ensure that you, your family, and your community have the tools necessary to live and breathe freely. Our commitment to quality, innovation, and community investment has made us a trusted name in the filtration industry for nearly 70 years.
