WaterFurnace 2428WF 24x28x1 replacement air filter for the following Waterfurnace Geothermal units: 6 Series Vertical Units: 022, 030, 026.
The Geothermal 2428WF MERV 11 air filter is approximately 24x28x1, the size recommended by WaterFurnace for a proper fit.
The 2428WF 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.
