The Honeywell CF108A1625/A Standard Air Cleaning Filter MERV 8 utilizes Easy Flow Energy Efficiency to capture an unprecedented amount of household airborne particles. Featuring a 15% microparticle capture rating, this air filter outperforms all other competing models in its class. This is matched by a level of 71% efficiency at filtering air particles flowing in large households such as pollen, household dust, airborne dust mite debris, mold spores, common allergens, clothing fibers and carpet fibers. These filters also have an incredibly durable and efficient lifespan that can reach up to 3 months of use.
MERV = 'Minimum Efficiency Reporting Value' this is used to rate the overall effectiveness of an Air Filter. Below you will find a table that measures the MERV strength and tells you the Application of each unit's effectiveness. In general an Air Filter with a higher MERV Rating is more effective and has a broader application, but most residential homes will find the best use from an air filter between the 5-12 MERV rating.
