MERV 8, 11 and 13 FILTERS
Holt Filters Inc. MERV 8, 11 and 13 pleated air filters provides high filtration performance with a low-pressure drop for energy efficiency. The MERV 8, 11 and 13 filter utilizes 100% synthetic fibers, high initial efficiency, no chemical binders, and does not absorb moisture. Holt Filters Inc. MERV 8, 11 and 13 HVAC air filters are designed to last up to 3 months.

Holt Filters, Inc. has a full line of pleated air filters to serve any application requiring medium ASHRAE efficiency. (Standard grade, Industrial or Commercial grade)

All of our Standard Commercial and Industrial Pleated air filters use the optimum blend of synthetic fibers to insure high dust holding capacity and filtering efficiency. The media is thermally glued to metal backing to prevent the media from sagging during the filter's use. The pleats are formed in a radial configuration to insure proper dust loading. The pleated cartridge is encapsulated in a heavy duty die cut beverage board frame to insure filter integrity in high moisture applications. The pleated filter cartridge is glued to the peripheral interior of the outer frame with a vinyl adhesive, preventing air by-pass. The face of the die cut is internally glued to the apexes of the pleats to insure maximum endurance under adverse conditions.

Holt Filters Inc. full line of pleated air filters is used in a broad range of installations, from pre-filters for higher efficiency air filters to primary filters for computer room units. Our filters offer longer life and higher dust holding capacities, and have been successfully used in upgrading from lower efficiency filters.

(Minimum Efficiency Reporting Value) are used by the HVAC (Heating, Ventilating and Air Conditioning) industry to describe a filter's ability to remove particulates from the air. A higher MERV rating means better filtration and greater performance. Holt Filter's Inc. now provides both MERV 8, 11 and MERV 13 HVAC air filters.
