MERV Ratings Decoded for Californians

For those who have shopped for air filters, "MERV ratings" is likely a familiar term. Created by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), MERV ratings, or the Minimum Efficiency Reporting Value, are used to compare the effectiveness of air filters in trapping airborne contaminants. This standard defines how efficiently an air filter captures particles, with a range of filters like MERV 8, 11, and 13 designed for varying conditions from residential spaces to polluted environments.

High-MERV filters like MERV 13 are capable of filtering out finer particles such as virus carriers, bacteria, and smoke, making them suitable for homes in polluted areas or occupants with severe respiratory issues. Filters with higher MERV ratings capture smaller particles more efficiently, which are more likely to penetrate deeply into the lungs and cause health issues.


Why Custom Air Filter Fit Matters

Custom air filters, such as furnace filters are designed to ensure that no untreated air, potentially laden with allergens and contaminants bypasses the filter. That's why you need to measure the exact filter size for your HVAC unit to fit precisely. These air filters come with features such as a self-sealing gasket, secure fasteners, and handles that you use to fasten them in place.

With these, you get maximum protection and have an easy time maintaining your unit. An adequately fitted air filter not only enhances indoor air quality but also promotes the longevity and efficiency of HVAC equipment.

Remember, an accurate air filter fit means it should sit snugly, without requiring bending or forcing, and shouldn't allow more than a one to two-finger width of space around the edges.
