Quest MERV 8 Replacement Filter for the Dual 110 and Dual 150
Quest part 4031062 is the pleated panel these two units breathe through. MERV 8 is the coarser end of the range, and on this chassis it is the only grade. MERV 8 is rated at 20 percent or better capture from 1 to 3 microns and 70 percent from 3 to 10. In practice that is the visible load: leaf dust, perlite grit, spent media. It will not do what a MERV 13 does down at the spore end. What it does do is keep that load off the evaporator coil. A coil that stays clean is a machine still making its rated pints, rather than drawing full power against a blinded face.
Quest Dual 110 and 150 Filter Size and Fit
This panel fits the Dual 110, unit part 4034220, and the Dual 150, unit part 4034230. Nothing else. The pair belong to the 10 Series. The panel measures 17.5 x 14 x 1.75 in. Match on part number 4031062 when reordering. On timing, check it every six months and change it at least that often. In agriculture, change it with every grow cycle. Skipping it has a cost. Running the unit without a filter, or with a less effective one, can clog the heat exchange coils and invalidates the warranty.
Key Features
- Quest part 4031062: The part number to match, one panel per unit
- MERV 8 standard pleat: Rated at 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: More media surface than a flat panel, so it holds more dust before airflow starts to suffer
- Keeps the evaporator coil clean: A clogged coil can need disassembly to clean, which is the repair this panel exists to prevent
- Holds rated capacity: A blinded face makes the unit draw full power for fewer pints, so fresh media is the simplest way to hold output
- Fits the Dual 110 and Dual 150: Unit parts 4034220 and 4034230, the 10 Series pair
- Six-month check and change: Both at six months, and a change with every grow cycle in agriculture
