Single Speed Vertical Units:NDV042, NDV048
Dual Capacity Vertical Units: NDV049
Vertical Units: LSV060
The Geothermal 59P509-07WF MERV 11 air filter is approximately 30x32x2, the size recommended by WaterFurnace for a proper fit.
The 59P509-05WF 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.
