Filterbuy 20x30x1 Air Filters MERV 8 (3-Pack)

Filtration Ratings and Performance 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 indicating the smallest microns captured.

Standard Protection (90% Airborne Particles): MERV 8 Air Filters These filters are perfect for almost any home or business seeking great indoor air quality at a reasonable rate. They effectively trap dust, pollen, and other particles 3-10 microns in size.

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

Optimal Protection (98% Airborne Particles): MERV 13 Air Filters Perfect for larger homes or businesses and those desiring the best possible filtration, these filters trap particles 0.3-1 microns in size, including bacteria.

Odor Elimination (90% Airborne Particles): MERV 8 Air Filters with Activated Carbon These filters not only provide standard MERV 8 protection but also use activated carbon to inhibit unpleasant odors, making them perfect for homes or businesses concerned with indoor air quality and smells.

Choosing the Right Filter Size Nominal Size vs. Actual Size: The nominal size is a rounded measurement (e.g., 16 x 20 x 1), while the actual size is the filter's precise dimensions (e.g., 15.50 x 19.50 x 0.75). All our filters display both.

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

Why Change Your Air Filter? Maintaining clean air is crucial for health, as dirty filters can contribute to asthma, allergies, and other respiratory issues. Additionally, old filters can reduce system efficiency, leading to higher energy costs and potential repairs.

When to Change Your Air Filter We generally recommend replacing your filter every 90 days to keep your HVAC system running efficiently and your air clean. However, this may vary based on factors like pet ownership, allergies, and household size.

Compatibility and Quantity Our filters are universally compatible with most furnaces, air conditioners, heat pumps, and HVAC systems, as long as you select the proper size. The number of filters needed depends on your specific requirements, and our selection includes packages ranging from 1 to 12 filters.

How to Change Your Air Filter After finding the right size, turn off power, remove the old filter, and insert the new one, ensuring the airflow direction matches. Then, replace the cover and restore power.
