Filterbuy 21x23x1 Air Filters (1-Pack), MERV 8 Pleated HVAC Replacement

Product Description:

Filtration Effectiveness and MERV Ratings The Minimum Efficiency Reporting Value (MERV) rates a filter's ability to capture particles, with higher MERV ratings indicating improved performance. Our air filters come in three key MERV options:

Standard Protection (MERV 8): Ideal for basic indoor air quality needs, trapping 90% of airborne particles 3-10 microns in size. Superior Protection (MERV 11): Perfect for homes with pets, smokers, or allergy sufferers, capturing 95% of particles 1-3 microns. Optimal Protection (MERV 13): The best filtration for larger spaces or those seeking maximum air purity, removing 98% of particles 0.3-1 micron.

We also offer MERV 8 filters with added activated carbon to help eliminate unpleasant odors.

Choosing the Right Fit When selecting a replacement air filter, pay attention to both the nominal size (rounded dimensions) and the actual size (precise measurements) printed on the frame. Measure your current filter to find the right match for your HVAC system.

Why Change Your Air Filter? Regularly replacing your air filter is essential for maintaining indoor air quality and protecting your HVAC equipment. Dirty filters can lead to increased energy costs, system malfunctions, and respiratory health risks.
