While you may automatically think that a higherMERV ratingmeans a better air filter, that's not always the case. Higher MERV ratings aren't always necessary and can decrease your unit's efficiency. The best MERV rating will be the one that suits your needs and lets your unit run efficientl...
An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream.
Your MERV ratings will fall into one of the four ranges listed below. Rating 1-4– These ratings are considered on the low end of the filters. These filters can remove the large contaminants that could cause damage if they were to work their way into the HVAC system. While...

MERV: The Minimum Efficiency Reporting Value is based on ASHRAE Standard 52.2 1999. This new rating system evaluates a filter at a particular air velocity over 12 particle sizes ranging from 0.3 to 10 microns. MERV values range from 1 to 16. A higher MERV indicates that a filter is more ...
Using the above determined values (E1 = 33.5%, E2 = 66.3%, and E3 = 86.8%) refer to Table 8.10 to determine the MERV rating. Under the 0.3–1.0 μm column, E1 at 33.5% fits the criteria of E1 < 75 therefore its MERV rating is 13 or lower based on this column. However, in th...
