You can improve the air quality in your home substantially with Honeywell's Whole-House Air Cleaner Filters. It's no secret that today's tightly-built homes trap dust, allergens and many more potentially hazardous contaminates. It's also none too surprising that poor indoor air quality ranks among the top five environmental risks to public health. Honeywell Air Filters (MERV 12 Rating) are 60x more efficient than a typical 1" fiber glass filter, plus they have the added ability of lasting up to one year. Honeywell Air Filters are also easy to install and come in accommodating sizes that fit all Honeywell and many Aprilaire, Space-Gard and Trion Air Bear models. Be certain to measure the filters you are replacing to make sure it's an exact match.
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.
