Our selection includes a variety of MERV-rated air filters to suit different needs. MERV 8 filters are perfect for standard protection, capturing 90% of airborne particles. MERV 11 filters offer superior protection, suitable for homes or businesses with factors like pets, smokers, and allergy sufferers. For optimal protection, MERV 13 filters are ideal for larger spaces or those seeking the best possible filtration.

We also offer MERV 8 air filters with activated carbon, perfect for inhibiting unpleasant smells while providing reliable MERV 8 quality.

When it comes to filter size, it's important to understand the difference between nominal and actual size. The nominal size is a rounded number, while the actual size reflects the filter's precise dimensions. Measuring your current filter and rounding up to the nearest inch will help you find the right nominal size.

Regularly changing your air filter is crucial for maintaining a healthy lifestyle and preventing potential system issues that could lead to unwanted expenses. We generally recommend replacing your filter every 90 days, though this may vary based on your specific needs.

Our air filters are universally compatible and will work with any furnace, air conditioner, heat pump, or HVAC system, as long as you choose the proper size. Changing the filter is a simple process of turning off the power, removing the old filter, and inserting the new one in the correct air flow direction.
