Filterbuy 20x25x4 MERV 13 Air Filters, 6-Pack

Measurement System and MERV Ratings

The Minimum Efficiency Reporting Value (MERV) rating system evaluates the ability of air filters to capture particles on a scale from 1 to 20, with 20 representing the smallest microns captured. This is a key metric to consider when selecting the right filter for your needs.

Standard Protection (90% Airborne Particles): MERV 8 Air Filters These filters are suitable for almost any home or business that desires reliable indoor air quality at a reasonable cost. They effectively trap dust, pollen, and lint.

Superior Protection (95% Airborne Particles): MERV 11 Air Filters Ideal for homes or businesses with factors like pets, smokers, or allergy sufferers, these filters provide enhanced performance by capturing smaller particles.

Optimal Protection (98% Airborne Particles): MERV 13 Air Filters Offering the best possible filtration, MERV 13 filters are perfect for larger spaces or those seeking the highest level of air purification, including bacteria.

Odor Eliminator (90% Airborne Particles): MERV 8 Air Filters with Activated Carbon These filters combine the standard MERV 8 performance with the added benefit of activated carbon to help inhibit unpleasant odors.

Choosing the Right Filter Size When selecting a replacement air filter, it's important to understand the difference between nominal and actual size. The nominal size is a rounded measurement, while the actual size reflects the filter's precise dimensions. Measuring your existing filter and rounding up to the nearest inch will help you find the correct nominal size.

Maintaining Healthy Air Quality Regularly changing your air filter is crucial for preserving a healthy indoor environment and preventing potential issues like asthma, allergies, and HVAC system problems. We generally recommend replacing the filter every 90 days, though the optimal frequency may vary based on factors like home size, pet ownership, and the presence of allergy sufferers.
