Pro Breeze 12L/Day Dehumidifier with Automatic Humidity Sensor Review

Where the 20L OmniDry is built for a full house or heavy laundry routine, the 12L model is sized for a single room, a small flat, or a caravan — Pro Breeze quotes a floor area of up to 162 sq ft (about 15 sq m). It uses the same automatic humidity sensor as the rest of the range: set a target between 30-80% and the compressor switches off once it's reached, rather than running continuously.

At under 38dB on its quiet setting, it's positioned by Pro Breeze specifically as suitable for a bedroom or home office, with a dedicated Sleep Mode alongside Auto and Continuous. The 1.8-litre tank is smaller than the 20L OmniDry's 4L, which is the main trade-off for the more compact footprint and lower price.

For a single bedroom, box room or small flat, run it in Auto mode targeting 45-55% — the review pattern consistently describes the unit clearing condensation on windows within a few days of regular use, in caravans, conservatories and older flats with persistent damp.

For overnight use, Sleep Mode dims the display and holds the fan on its quietest setting — several long-term reviewers report running it next to the bed without disruption, though a genuinely light sleeper may still notice the compressor cycling on and off.

Because the tank is smaller than the 20L OmniDry's, expect to empty it daily in a genuinely humid room during the first few weeks of use, tapering off as ambient humidity drops toward the target.
