Filterbuy 20x20x2 MERV 13 Air Filters (12-Pack)

Filtration Ratings Explained The Minimum Efficiency Reporting Value (MERV) is a scale that rates the effectiveness of air filters in trapping particles, ranging from 1 to 20 (with 20 capturing the smallest microns).

Standard Protection (90% Airborne Particles) MERV 8 Air Filters Ideal for most homes or businesses seeking great indoor air quality at a reasonable rate.

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

Optimal Protection (98% Airborne Particles) MERV 13 Air Filters Recommended for larger spaces or those who want the best possible filtration.

Odor Eliminator (90% Airborne Particles) MERV 8 Air Filters with Activated Carbon Helps inhibit unpleasant smells while providing reliable MERV 8 quality.

Understanding Filter Sizing Nominal Size vs. Actual Size: The nominal size is a rounded number (e.g., 16 x 20 x 1), while the actual size depicts the filter's precise dimensions (e.g., 15.50 x 19.50 x 0.75). Both are provided.

Measuring Your Air Filter: If your current filter lacks dimensions, use a tape measure to record the width, length, and depth. Round these measurements up to the nearest inch to find the corresponding nominal size.

Why Change Air Filters? Maintaining clean air is crucial for health, as dirty filters can lead to respiratory issues and system inefficiencies. We generally recommend replacing filters every 90 days, though this may vary based on factors like pet ownership and allergy concerns.

Ensuring a Perfect Fit Our filters are compatible with most HVAC systems. If you see a specific brand name, ensure it matches your unit model. The number of filters needed depends on your home's venting requirements.

Changing the Filter Turn off power, remove the old filter, and insert the new one in the direction of airflow. Then replace the cover and restore power.
