The Measurement System and MERV Rating

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. This measurement system provides a clear understanding of a filter's performance capabilities.

Standard Protection (90%): MERV 8 Air Filters These filters are perfect for almost any home or business, delivering great indoor air quality at a reasonable rate. They trap 90% of airborne particles between 3-10 microns in size, including dust, debris, and dander.

Superior Protection (95%): MERV 11 Air Filters
Ideal for homes or businesses with factors like pets, smokers, and allergy sufferers, MERV 11 filters capture 95% of particles between 1-3 microns, including smog and smoke.

Optimal Protection (98%): MERV 13 Air Filters Offering the best possible filtration, MERV 13 filters are perfect for larger homes or businesses. They trap 98% of particles between 0.3-1 microns, including bacteria.

Odor Eliminator (90%): MERV 8 with Activated Carbon These filters provide reliable MERV 8 quality while also inhibiting unpleasant smells, making them perfect for homes or businesses wanting to address odors.

Choosing the Correct Filter Size The nominal size is a rounded measurement, while the actual size depicts the filter's precise dimensions. Measure your current filter to find the right fit for your system.

Why Change Air Filters? Replacing filters every 90 days maintains a healthy lifestyle, as dirty air can lead to respiratory issues. Plus, old filters can cause system defects, leading to higher energy costs and repair needs.
