WaterFurnace 30321WF 30x32x1 replacement air filter for Waterfurnace Geothermal units.

The Geothermal 30321WF MERV 11 air filter is approximately 30x32x1, the size recommended by WaterFurnace for a proper fit.

The 30321WF is made of 100% synthetic fibers that are needled together and then electro statically charged.  The needled fibers create a dense mat that produces a MERV 11 rating and higher mechanical efficiency at a lower air resistance than other pleated filters. 

The manufacturer suggested replacement interval is 4 to 6 months, depending upon conditions and lifestyle.
