Quest MERV 8 Filter, 16 x 16 x 2, Matched by Size
Most replacement filters are identified by the machine they belong to. This one is not. It is a MERV 8 standard pleat at 2 x 16 x 16 inches, part 4021799-01. So the honest way to match this panel is on the measurement rather than on a model list. Measure the opening in your unit. If it takes a 16 x 16 x 2, this is the Quest part for it.
What MERV 8 Does at This Size
MERV 8 is the coarse end of the pleated range. The EPA holds it to 20 percent or better capture from 1 to 3 microns and 70 percent from 3 to 10. That covers the visible load in a working space: settled dust, leaf litter, grit. It is not a spore filter, and nothing about the grade pretends otherwise. The pleats matter more than the number here. Folding the media multiplies the face area inside the same frame, so the panel holds far more debris before back pressure climbs. Match on the opening and the part number.

- Quest part 4021799-01: The part number to match, one panel per unit
- 16 x 16 x 2, matched by size: The opening is what decides the fit
- MERV 8 standard pleat: EPA holds the grade to 20 percent or better from 1 to 3 microns and 70 percent from 3 to 10, which covers the visible load
- Pleated for face area: Folding the media multiplies surface inside the same frame, so it holds more debris before back pressure climbs
- Not the Dual 110 or 150 filter: Those take a 17.5 x 14 x 1.75 MERV 8, Quest part 4031062, which is a different panel
