Best dehumidifier UK under £100 — what's the catch?
Under £100 you're almost always looking at a Peltier mini unit rather than a compressor model — extraction rates around 250-500ml a day rather than 12-20 litres. That's genuinely useful for a small bathroom, wardrobe or caravan, but won't touch a damp bedroom or dry laundry. If your problem is genuine room-wide damp, it's worth saving for a compressor unit rather than buying a budget model that won't solve it.
