# Spacekey OL09-D031UCN2B1/E 34-Pint Dehumidifier

Spacekey OL09-D031UCN2B1/E is a compressor dehumidifier listed for residential spaces up to 2,500 square feet. It combines a claimed 34-pint daily removal capacity with humidity control, three modes and a drain-hose option, though the small water tank makes continuous drainage worth considering for sustained use.

## At a glance

- Manufacturer claims removal of up to 34 pints per day at 95°F and 90% RH, with coverage up to 2,500 square feet.
- Three listed operating modes are dehumidifying, clothes drying and sleep. The listing also describes adjustable humidity settings from 30% to 80% RH.
- The listing claims a 3.5 ft gravity drain hose, plus tank auto-shutoff with an indicator light and audible alarm.
- A 24-hour timer, automatic defrost, washable filter, handle and rolling casters are claimed features.

## Pros

- The claimed continuous-drain hose option can reduce the need to empty the tank manually during ongoing use.
- Adjustable humidity control and distinct drying and sleep modes offer more choices than a single basic operating setting.
- The listed washable filter is reusable rather than described as a disposable replacement.

## Cons

- The listed 0.66-gallon tank is small relative to the claimed daily moisture-removal capacity, so tank-based operation may require frequent emptying in humid conditions.

## A good fit for

- Households seeking a residential dehumidifier with adjustable humidity and multiple operating modes.
- Users with a suitable gravity-drain location who want to reduce manual tank emptying.
- People considering humidity control for basements, bedrooms, bathrooms or other listed home spaces.

## Customer feedback

Customer feedback describes effective moisture reduction and fresher-feeling air, with positive mentions of the design and home-use suitability. That is relevant to its stated residential purpose, but does not verify the claimed 34-pint capacity or coverage. The small feedback sample also includes a notable one-star share, so the favorable comments do not establish consistent results.
- Positive themes: Customer feedback highlights perceived moisture reduction and fresher air.
- Positive themes: Design and general home-use suitability are also described positively.
