1″ Geothermal Filters
We now offer a MERV 8 & a MERV 11 filters. The Merv 8 is good the MERV 11 is better. MERV (Minimum Efficiency Reporting Value) is an industry standard which rates the ability of a filter to trap particles 0.3 to 10.0 microns from the air we breathe. Most ordinary, inexpensive filters found at hardware stores are MERV 4 or lower—they are simply ineffective in capturing smaller particles. In addition, filters are pleated to increase the surface area allowing for more holding capacity and less frequent replacement.

Electronic Filter Media
The AlpinePure ET creates an active electric field to capture airborne particles with efficiencies of 97% at 0.30 microns. Electronic media air cleaners do an excellent job of removing submicron particles by the process of agglomeration—polarized particles bond with other charged particles in the air and are easily removed through the filter. Carbon center screens are included to trap odors and volatile organic compounds. The AlpinePure ET is a media is easy to replace. Unlike other electronic air cleaners, the AlpinePure ET creates no harmful ozone or annoying “zapping” noises. QTY 1 is a 3 pack of replacement filter.
