Quest Pre-Filter for Quest 70 Pint Dehumidifier. 9 x 11.38 x 0.75

The Quest 70 Pint Pre-Filter and What It Saves the Panel Behind It A pre-filter does one job. It catches the big, obvious debris before that debris reaches the pleated media doing the fine work. In a flowering room that means leaf fragments, trimmed material, hair and the settled dust that comes off every surface when a fan spins up. None of it needs a MERV 13 panel to stop it, and all of it will blind one early if it gets there. Running this in front means the 4037724 behind it spends its service life on spores and sub-micron dust. It stops filling up with debris you could have caught for less. Quest 70 Pre-Filter Size This pre-filter shares the slot with the Quest 70's MERV 13 panel and matches that panel's measured size exactly. It carries no MERV rating, because a pre-filter is not graded media. On timing, the 70's main filter is on a three-month check. A pre-filter loading faster than the panel behind it is the normal outcome, not a fault.
