CUBair MERV 6

MERV stands for Minimum Efficiency Reporting Value. It is an industry standard that rates the efficiency of air filters. Higher MERV ratings capture more and smaller particles, but they may slightly reduce airflow.

Check the size printed on the outer frame of your current filter or measure the length, width, and depth directly. Use the nominal size (e.g., 14 x 20 x 1) for ordering replacements.

Look for an arrow on the side of the filter indicating airflow direction. Install the filter with the arrow pointing towards the HVAC unit or fan.

Replace filters every 1-3 months for standard use or more frequently if you have pets, allergies, or high usage. Learn more here

Higher MERV filters provide better filtration but may reduce airflow in systems not designed for them. Consult your HVAC manufacturer.

Synthetic media filters are durable and resist moisture, while fiberglass filters are cost-effective but may degrade faster in humid environments.

Replace filters regularly, use the correct MERV rating, and ensure your system is maintained for optimal airflow and energy efficiency.
