MERV 13 Filter for Quest 506, 746, and 876 Dehumidifiers

Larger commercial dehumidifiers pull a high volume of air through their filtration stage, so upgrading filter efficiency matters more as unit size grows. This MERV 13 filter measures 18 x 20 x 2 inches and is rated 65% more effective than a MERV-8 filter and 20% more effective than a MERV-11 filter at capturing airborne particulate.

It fits the Quest 506, 506 277V, 746, and 876 dehumidifiers, and each of these units takes two filters, so order in pairs when replacing.

Frequently Asked Questions

Which dehumidifiers use this filter?

It fits the Quest 506, 506 277V, 746, and 876 dehumidifiers. All four models share the same 18 x 20 x 2 inch filter size.

How many filters does each unit need?

Each of these units takes two filters, so order a pair when it's time to replace them. Running with only one filter installed leaves the second slot open to unfiltered air.

How much better is MERV 13 than lower ratings?

It's rated 65% more effective than a MERV-8 filter and 20% more effective than a MERV-11 filter at capturing airborne particulate. That includes finer dust, mold spores, and similar contaminants that lower-rated filters can miss.

When should these filters be replaced?

Replace both filters together once airflow drops noticeably or the media looks visibly loaded with dust. Heavier particulate environments may call for more frequent changes.
