Quest MERV 8 Air Filter for Quest 10 Series - 17.5in x 14in x 1.75in

MERV 8 Replacement Filter for the Quest 10 Series Dehumidifier

This is a genuine replacement filter for the Quest Dual 110 and Dual 150 dehumidifiers, rated MERV 8 -- a lower-resistance filtration grade matched to how these particular units are engineered to move air.

It's built from 100% synthetic filter media at 17.5in x 14in x 1.75in and captures pollen, dander, lint, and dust mites, with a recommended replacement interval of every 3 months.

Key Features & Benefits

• MERV 8 filtration rating — captures pollen, dander, lint, and dust mites at an efficiency level matched to the Dual 110 and Dual 150 blower design.
• 100% synthetic filter media — holds up consistently through its service life rather than degrading the way basic fiberglass media can.
• Genuine replacement fit — sized specifically for the Quest Dual 110 and Dual 150 dehumidifiers at 17.5in x 14in x 1.75in.
• 3-month replacement interval — a defined replacement schedule rather than a vague run-until-dirty guideline, making filter stocking easier to plan.
• Matched airflow resistance — MERV 8 keeps resistance low enough for these units' blower specification, which is why it's the factory rating rather than a compromise choice.

Who Should Use This

This filter is for operators of Quest Dual 110 or Dual 150 dehumidifiers who need a genuine replacement filter matched to the unit's designed airflow specification, on the manufacturer's recommended 3-month replacement schedule.

About Quest

Quest is a Therma-Stor brand. It focuses on commercial dehumidification. Therma-Stor is headquartered in Madison, Wisconsin. It's the same parent company behind the Anden brand. Therma-Stor has built dehumidifiers and environmental-control equipment for decades. Quest specifically targets commercial and industrial moisture control. Think indoor cultivation, food production, and commercial buildings. That's a different focus than residential basement units. Many overhead models use the company's patented M-CoRR design. M-CoRR stands for multi-coil refrigeration. The design recycles heat pulled from the air. That happens during dehumidification itself. It improves energy efficiency as a result. It also cuts heat sent back into the room.

Frequently Asked Questions

What models is this filter compatible with?

This MERV 8 filter is sized for the Quest Dual 110 and Dual 150 dehumidifiers at 17.5in x 14in x 1.75in. Confirm your exact model before ordering, since it isn't interchangeable with the MERV 13 filters used on Quest's larger commercial units.

Why is this filter MERV 8 instead of a higher rating like MERV 13?

Quest matches each dehumidifier's factory filter rating to that unit's blower design, and the Dual 110 and Dual 150 are built around a MERV 8 specification. Installing a much higher-MERV filter on a unit not designed for it can add airflow resistance the blower wasn't sized to handle.

How often should this filter be replaced?

The manufacturer recommends replacing this filter every 3 months under typical operating conditions. Dustier environments may call for more frequent inspection and earlier replacement.

What does this filter capture?

It captures pollen, dander, lint, and dust mites, the particle range appropriate to a MERV 8 rating. It won't capture the finer particles like bacteria and smoke that a MERV 13 filter is rated for, which is a tradeoff built into the Dual 110/150 platform's design, not a shortcoming of this specific filter.
