Let's explore the various MERV ratings and their benefits:

MERV 8 Air Filters (Standard Protection, 90% Effectiveness): Perfect for almost any home or business seeking great indoor air quality at a reasonable rate.

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

MERV 13 Air Filters (Optimal Protection, 98% Effectiveness): Suitable for larger homes or businesses, and those seeking the best possible filtration experience.

MERV 8 Air Filters with Activated Carbon (Odor Eliminator, 90% Effectiveness): Perfect for inhibiting unpleasant smells while providing reliable MERV 8 quality.

When it comes to choosing the right filter size, the nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. Measure your current filter to find the actual size, then round up to the nearest inch to determine the nominal size.

Replacing air filters regularly is crucial for maintaining a healthy lifestyle, as dirty air can lead to various respiratory issues. We generally recommend changing your filter every 90 days to keep your system running efficiently and the air clean.

Our filters are designed to be universally compatible with any furnace, air conditioner, heat pump, or HVAC system, as long as you select the proper size. The number of filters needed varies based on individual requirements, but our selection includes package quantities ranging from 1 to 12 filters.
