We compared the dehumidifiers Irish households actually buy — on extraction rates, electricity cost per litre removed, noise, and how fast they dry a winter washing load. The five below cover every budget from €160 to €330. One spoiler: the brand that dominates this market (Meaco) earns its position, but it isn't the right answer for every room.

Buying guide: how to choose
Compressor vs desiccant
Compressor models are cheaper to run and ideal for typical Irish indoor temps (15–25°C). Desiccant models work better in cold spaces — garages, unheated rooms under 15°C — but use roughly double the electricity. Most homes want a compressor unit.
Size by litres per day
The headline number (10L, 12L, 20L) is extraction per day under test conditions. Rule of thumb: 10–12L for apartments and bedrooms, 20L for a 3-bed house with drying laundry, 25L+ for big or very damp homes.
Running costs at Irish rates
A modern 12L compressor unit draws ~160 W: about 5–6 cents per hour. Run 8 hours daily and you spend roughly €12–15 a month — usually less than the heating energy wasted evaporating damp air, which is why a dehumidifier can lower total bills.
Laundry mode is the killer feature
If you dry clothes indoors (most of Ireland, most of the year), laundry mode pays for the machine: a good unit dries a load overnight for ~6 cents of electricity versus ~€1.50+ per tumble-dryer cycle, and without the condensation hitting your walls.
Frequently asked questions
What size dehumidifier do I need for an Irish home?
Apartments and single rooms: 10–12L/day. Standard 3-bed semi: 20L. Large, old or very damp houses: 25L+. Oversizing slightly is fine — bigger units hit target humidity faster and then idle, which is actually more efficient.
How much does a dehumidifier cost to run in Ireland?
A 12L compressor model at ~160 W costs about 5–6 cents per hour at typical rates. Eight hours a day works out around €12–15 per month. Desiccant models cost roughly double — but heat the room as a side effect.
Will a dehumidifier stop mould and condensation?
Yes, if you keep relative humidity under 60%. Mould cannot establish below that level. Run the unit on auto with a 50–55% target, keep furniture slightly off cold external walls, and wipe existing mould once with a fungicidal cleaner.
