Black Friday 2026 dehumidifier deals: what to buy and which prices have moved

Updated 13 November 2026

Black Friday is on Friday 27 November 2026, with Cyber Monday on Monday 30 November. It lands in the middle of the damp season, when condensation streams down the windows, wet washing hangs on radiators and mould starts to creep into bathroom and bedroom corners. A dehumidifier is one of the few appliances that tackles all three, so it is no surprise that people look for a deal now. This page shows which prices have moved on the models we review, and how to avoid buying the wrong one just because it is cheaper.

Prices on the move

We compared the price of each model on 13 November 2026 with its price in our early-November checks. Only a fall of 5% or more is shown below. These are not manufacturer or retailer savings claims, just the change we recorded between those two dates.

Prices were last checked on 13 November 2026 and can change at any time. Open each review to see the current price and the full verdict.

Before Black Friday: pick the right size first

A discount does not turn the wrong machine into the right one. Capacity (litres per day) matters more than price: around 10-12L suits a flat or a single bedroom, 20L suits a 3-5 bedroom house or anyone who dries laundry indoors every week, and 25L and above suits large or very damp properties.

Check the running cost too. Two models with the same extraction rate can differ in power draw, and a unit with a humidistat that switches off once your target is reached will cost far less over a winter than one left running flat out. Our buying guide walks through each step.

Six checks before you click "Buy"

  1. The exact model and capacity: a 12L and a 20L unit from the same brand are not the same product.
  2. The temperature range: a compressor unit loses efficiency below about 10-15°C, so a cold garage needs a desiccant model.
  3. The tank size and whether continuous drainage with a drain hose is possible.
  4. The noise level in dB(A), especially for a bedroom.
  5. The warranty length: some brands offer five years, others one.
  6. The final price, including delivery, against the price you noted before the sales began.

Frequently asked questions

When is Black Friday 2026?

Black Friday falls on Friday 27 November 2026, followed by Cyber Monday on Monday 30 November. Some retailers start early deals in the weeks before, while stocks last.

Are dehumidifiers cheaper on Black Friday?

Some models fall in price, others do not, and it varies by retailer. Our own checks showed several prices lower on 13 November than in early November, but prices change daily. Note the price of the model you want now, then compare it on the day.

Is November a good time to buy a dehumidifier?

It is the start of the damp season: heating goes on, windows stay shut, condensation appears on glass and washing dries slowly indoors. If you already have mould or a musty smell, waiting for a few pounds off may cost you more in cleaning than you save. See our guide to the best dehumidifier for mould.

How can I tell if a Black Friday dehumidifier deal is genuine?

Ignore the crossed-out 'was' price and compare against the price you noted yourself. Check the exact model and capacity (a 12L unit is not a 20L unit), the warranty, and whether delivery is included. Our buying guide explains what to check.

Which size dehumidifier should I buy in the sales?

Do not let a discount choose the size for you. Around 10-12L/day suits a flat or a single room, 20L/day suits a 3-5 bedroom house or regular laundry drying. Start with the best dehumidifier UK comparison.
