Quest MERV 11 Standard Pleat Filter, 16" x 20" x 2"

MERV 11 Pleat Filter for Quest Dual 105-225 Dehumidifiers

Dehumidifiers pull contaminated air through an intake filter before conditioning it, and that filter needs periodic replacement to keep airflow and filtration performance from degrading over time. This Quest MERV 11 standard pleat filter is sized 16 x 20 x 2 inches, a direct-fit replacement across six related Quest units.

It fits the Quest Dual 105, 155, 165, 205, and 225 dehumidifiers, along with the 155 50-Hz variant, so one replacement filter covers most of that model line.

Frequently Asked Questions

Which dehumidifiers does this filter fit?

It fits the Quest Dual 105, 155, 165, 205, and 225 dehumidifiers, plus the 155 50-Hz variant. Confirm your unit's model number before ordering, since Quest filters aren't interchangeable across every product line.

What size is this filter?

It measures 16 x 20 x 2 inches, sized as a direct-fit replacement for the compatible models. No trimming or adapter hardware is needed.

How often should I replace this filter?

Check it on a regular maintenance schedule and replace it once airflow noticeably drops or the filter media looks visibly loaded with dust. Growing environments with heavier particulate loads may need more frequent changes.

What does MERV 11 mean?

MERV 11 is a mid-tier filtration rating that captures everyday dust, pollen, and similar airborne particulate without excessively restricting airflow through the dehumidifier. It's a common baseline rating for standard-duty pleat filters.

Is this an OEM-spec Quest part?

Yes, it's sized and rated to match the original filter specification for these Quest dehumidifier models. Installing a properly sized and rated filter helps the unit maintain its intended airflow and filtration performance.
