Overview
An owner of a closet, safe, pantry, RV or boat gets a cordless silica gel dehumidifier that works silently. When the gel is full, you plug it in to dry it out and reuse it.
No batteries or refills are needed, and it renews itself on a wall outlet. The coverage is small, so it suits compact spaces only.
Who it's for
Owners of small enclosed spaces such as safes, closets and pantries will use the silent operation and renewable gel. Those with a damp room or basement should look at a full-size dehumidifier.
Pros and cons
- Cordless with no batteries
- Renewable by plugging in
- Indicator window shows saturation
- Includes a hanging hook
- Very small coverage
- Small water capacity
- Must be renewed regularly
Performance notes
Silica gel adsorbs moisture from the air until it saturates, and the indicator window shows when that happens. Plugging the unit in heats the gel and drives the water out, so it can absorb again. Coverage is limited to the stated volume.
