10x30x1 Air Filter MERV 11 Allergen Defense (12-Pack)

Filtration Ratings Explained The Minimum Efficiency Reporting Value (MERV) rates a filter's ability to capture particles on a scale of 1-20, with 20 representing the smallest microns captured. This measurement helps determine the appropriate filtration level for your home or business needs.

Standard Protection (90% Airborne Particles) MERV 8 Air Filters These filters are perfect for most homes or businesses seeking reliable indoor air quality at a reasonable cost. They capture 90% of airborne particles 3-10 microns in size.

Superior Protection (95% Airborne Particles) MERV 11 Air Filters Ideal for environments with pets, smokers, or allergy sufferers, these filters capture 95% of particles 1-3 microns in size, including smog and smoke.

Optimal Protection (98% Airborne Particles) MERV 13 Air Filters The best filtration option for larger spaces or those seeking maximum air purification, MERV 13 filters trap 98% of particles 0.3-1 micron, including bacteria.

Odor Eliminator (90% Airborne Particles) MERV 8 Air Filters with Activated Carbon These filters not only capture 90% of 3-10 micron particles, but also help inhibit unpleasant household odors through the use of activated carbon.

Choosing the Right Fit When selecting a replacement filter, pay attention to both the nominal size (rounded measurement) and the actual size (precise dimensions) to ensure proper fit for your HVAC system.

Why Change Filters Regularly? Replacing air filters every 90 days helps maintain healthy indoor air quality, prevent system damage, and reduce energy costs. Factors like pet ownership, allergies, and household size may require more frequent changes.
