The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with 20 capturing the smallest microns. MERV 8 filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate. MERV 11 filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers. MERV 13 filters are perfect for larger homes or businesses, and those who want the best possible filtration experience. MERV 8 filters with Activated Carbon are perfect for homes or businesses that want to inhibit unpleasant smells with reliable MERV 8 quality.

Choosing the correct filter size is important. The nominal size is a shorthand number rounded to the nearest whole or half inch, whereas the actual size is an exact measurement depicting the filter's precise dimensions. Replacing air filters regularly is crucial for maintaining a healthy lifestyle, as dirty air can lead to respiratory issues. We generally recommend replacing filters every 90 days to keep your system running efficiently and air clean.

We believe that everyone deserves to breathe clean air, which is why we offer a variety of expert services and hundreds of custom air filter sizes compatible with a near infinite number of systems.
