Filterbuy 20x25x1 MERV 13 Air Filters (3-Pack)

Measurement Systems and MERV Ratings Explained

The Minimum Efficiency Reporting Value (MERV) is a scale that rates the ability of air filters to capture particles, ranging from 1 to 20 (with 20 trapping the smallest microns).

Standard Protection (90% Airborne Particles) - MERV 8 Air Filters These filters are perfect for most homes or businesses seeking great indoor air quality at a reasonable cost.

Superior Protection (95% Airborne Particles) - MERV 11 Air Filters Ideal for homes or businesses with factors like pets, smokers, or allergy sufferers.

Optimal Protection (98% Airborne Particles) - MERV 13 Air Filters Perfect for larger spaces or those wanting the best possible filtration experience.

Odor Eliminator (90% Airborne Particles) - MERV 8 with Activated Carbon These filters inhibit unpleasant smells while providing reliable MERV 8 quality.

Choosing the Right Fit The nominal size is a rounded number (e.g., 16x20x1), while the actual size reflects the filter's precise dimensions (e.g., 15.50x19.50x0.75). Both are listed to ensure you find the perfect match.

Why Change Filters Regularly? Maintaining clean air is crucial for health, as dirty filters can lead to asthma, allergies, and other respiratory issues. Plus, old filters can cause system problems, increasing energy costs and repair needs.

We generally recommend replacing filters every 3 months, though timing may vary based on factors like pets, allergies, and household size.
