Optimal Protection (98%) MERV 13 Air Filters The best choice for larger spaces or those requiring the highest level of filtration. MERV 13 filters trap 98% of particles as small as 0.3-1 microns.

Odor Eliminator (90%) MERV 8 Filters with Activated Carbon Combines standard MERV 8 protection with the odor-absorbing properties of activated carbon, making them ideal for homes or businesses concerned about unpleasant smells.

Finding the Right Fit When selecting a replacement air filter, it's important to know the difference between the "nominal" and "actual" size. The nominal size is a rounded measurement, while the actual size reflects the filter's precise dimensions. Measure your existing filter to determine the right fit for your HVAC system.

Why Change Your Air Filter? Regularly replacing your air filter is essential for maintaining indoor air quality and equipment efficiency. Dirty filters can compromise respiratory health and lead to increased energy costs and system repairs. We generally recommend changing your filter every 3 months, but this may vary based on your specific needs.
