A Comprehensive Guide to MERV Ratings and Replacement Air Filters

Understanding MERV Ratings: The Minimum Efficiency Reporting Value (MERV) is a rating system that measures the ability of air filters to capture particles on a scale of 1 to 20, with 20 capturing the smallest particles.

Standard Protection (90%): MERV 8 Air Filters are suitable for most homes or businesses seeking great indoor air quality at a reasonable cost. They capture 90% of airborne particles ranging from 3 to 10 microns.

Superior Protection (95%): MERV 11 Air Filters are ideal for homes or businesses with factors like pets, smokers, or allergy sufferers. They capture 95% of airborne particles ranging from 1 to 3 microns.

Optimal Protection (98%): MERV 13 Air Filters are perfect for larger homes or businesses, and those who desire the best possible filtration experience. They capture 98% of airborne particles ranging from 0.3 to 1 micron.

Odor Eliminator (90%): MERV 8 Air Filters with Activated Carbon are perfect for homes or businesses that want to inhibit unpleasant smells while maintaining reliable MERV 8 quality.

Choosing the Right Filter Size: The nominal size is a rounded number (e.g., 16x20x1), while the actual size is the precise measurement (e.g., 15.5x19.5x0.75). Measure your existing filter and round up to the nearest inch to find the corresponding nominal size.

Maintaining Indoor Air Quality: Replacing your air filter every 90 days helps keep your HVAC system running efficiently and your air clean, especially for those with pets, allergies, or households with children.
