Merv 11 furnace filters and air conditioner filters are extended surface pleated panel filters designed for use in all types of residential, commercial, and industrial air filtration systems. Multi-Pleat filters, because of their high quality filter media and extended surface construction, offer significantly higher efficiency and longer service life than fiberglass disposable filters. These filters are available in a wide range of standard and custom sizes.
The media is made of continuous polyolefin fibers, which are thermally bonded together. This fiber structure has increasing fiber density from the upstream to the downstream side. This media construction, coupled with a proprietary electrostatic treating technology, allows filters made with Intrepid Media to achieve high initial and sustainable filtration efficiencies.
Online Allergy Relief’s furnace filters and air conditioner filters attain a Minimum Efficiency Reporting Value per ASHRAE 52.2 Test Standard for the MERV 11. The furnace filters and air conditioner filters have a high dirt holding capacity for long life. The media used in the Merv 11 furnace filters and air conditioner filters is thermally bonded using no chemical binders and the continuous fibers prevent shedding. They have excellent bi-directional strength. The Merv 11 furnace filters and air conditioner filters use fibers that are electrostatically treated. The Merv 11 furnace filters and air conditioner filters use no fiberglass in the construction. The fibers will not absorb moisture that would support microbial growth.
