Tanness 12L Dehumidifier with Humidity Display & Sleep Mode

An entry-to-mid-range 12L home dehumidifier aimed at everyday damp, condensation and indoor laundry drying. The humidity display and sleep mode make it easier to use in bedrooms or busier living spaces, while the continuous drainage option matters if you do not want to keep emptying a tank.

This one made sense because the feature set is practical rather than flashy: digital humidity display, laundry mode and a sleep setting at a mid-range spend. There is enough review history for the 4.5-star average from 464 ratings to mean something. My main caution is to check tank size and noise before treating it as an easy bedroom pick.

What matters in this category

With dehumidifiers, the useful details are extraction rate, tank size, drain options, noise and the room size they are meant to cover. Fancy modes matter less than whether the unit can keep up with your damp problem. For bedrooms or laundry drying, a clear humidity display and a proper sleep setting are more useful than a long list of buttons.

Best for
  • Handy if condensation builds up on windows and you want a visible humidity reading, not just on-off drying.
  • A solid fit for drying washing indoors faster, thanks to the dedicated laundry mode.
  • Makes more sense for steady whole-room damp control than a tiny space where a mini unit would do.
Skip if
  • Skip it if you need a very compact unit for a box room, as 12L models are usually bulkier than small desktop types.
  • Pass if near-silent running is your top priority, because sleep mode helps but does not guarantee whisper-free operation.
  • Look elsewhere if you want smart app controls, since those are not part of the listing.
What to check on Amazon
  • Confirm whether a continuous drain hose is included, or if you need to buy one separately.
  • Check the water tank capacity, as that affects how often you will empty it in normal use.
  • Look for the quoted noise level in decibels if it will run in a bedroom or near a desk.
  • Make sure the recommended room size matches your space, especially for laundry drying or heavy condensation.
Price judgement

At £67.20, this sits in a fair middle spot for a 12L dehumidifier: not a throwaway buy, but easier to justify with the humidity display, laundry mode and solid review depth.

Quick questions

Is 12L enough for everyday damp and condensation?

For many homes, yes. A 12L model is usually aimed at regular moisture control in lived-in rooms and can also help with drying washing, but room size and how damp the space gets still matter.

Can it be left to drain continuously?

The title says it supports continuous drainage, which is handy if you do not want to keep emptying the tank. It is still worth confirming whether the hose is included in the box.

Would this suit a bedroom?

It has a sleep mode and the listing presents it as quieter-running, so it is more bedroom-friendly than some basic units. Even so, check the decibel figure if light sleep or overnight use is a concern.

Try a couple of nearby options before you leave

If this one is close but not quite right, compare it with smaller units for a single room, or step up if you have a larger damp area or want quicker clothes drying. The main trade-off is size: compact models save space, while bigger ones usually need less emptying and cope better with stubborn moisture.
