NETTA Dehumidifier 800ml Mini Air Dehumidifier (White, Energy Class A+++)
Product description
The essentials
If you’re dealing with damp patches, that stale, humid feel, or condensation that keeps coming back, a mini dehumidifier like the NETTA 800ml is designed for one straightforward job: removing moisture from the air where you need it most.
This model is positioned as a compact, portable option for smaller spaces. The idea isn’t to replace a whole-house system, it’s more about targeting problem areas such as a bathroom between showers, a cupboard that never quite feels “dry”, or a bedroom that tends to hold onto dampness overnight.
The headline figure here is that it can extract up to 330ml of excess moisture per day, depending on conditions. It also comes with an auto shut-off when the water tank is full, plus an indicator light that lets you know when emptying is needed.
What you’ll notice in everyday use
On paper, the practical appeal is that it’s meant to be easy to live with. The water tank is detachable, so emptying isn’t a wrestling match, you can lift it out and pour away the collected water.
Noise is another thing people care about with these small units. NETTA quotes a running noise level of no louder than 35 decibels, which should be suitable for use while you’re working, sleeping, or spending time in the room.
There’s also an energy-efficiency angle. It’s rated at 22 watts, and the brand states it should cost less than 1p per hour to run. Whether your exact costs line up will depend on your tariff and how often you run it, but the low power draw is clearly part of the pitch.
One small limitation to keep in mind: dehumidifiers like this are more effective when the room isn’t too cold and when humidity is already reasonably high. The recommended working environment is over 15°C and over 40% relative humidity, so if your space runs colder than that, results may feel underwhelming.
Key points
The NETTA mini dehumidifier targets damp and moisture in everyday rooms.
With up to 330ml/day extraction (conditions-dependent) and a compact footprint, it’s the sort of unit you can place where moisture builds up—bathroom, kitchen, bedroom, wardrobe, or even a basement area.
It’s also built for convenience: a detachable tank, an auto shut-off at full capacity, and a red indicator light to flag when the tank needs emptying.

Where it shines (and where it might not)
This is the kind of dehumidifier that makes sense when your damp problem is local and you want something that can be moved around. If you’re trying to keep a small bedroom cupboard from getting musty, reduce condensation around a wardrobe, or take the edge off humidity in a bathroom, its compact size and tank-emptying design are well suited to that.
It may not be the best fit if you need strong, whole-room drying over long periods—because the stated extraction capacity is aimed at smaller spaces and the recommended conditions matter. If your home is consistently cold or your humidity level sits below what the manufacturer suggests, you might find it doesn’t keep up.
It’s also worth being realistic about mould prevention. Removing moisture helps, but it won’t fix underlying causes like poor ventilation, hidden leaks, or persistent condensation caused by external factors. In those situations, this can be part of the solution, but not the full solution.
Best use cases
Imagine you’ve got condensation after showers, and the bathroom feels damp the next morning. Running this mini dehumidifier in the bathroom area can help pull moisture out of the air so the room doesn’t sit humid.
Or picture a wardrobe with a slightly “stuffy” smell. Put the unit nearby (it’s small enough to fit into awkward corners), let it run for a while, and empty the tank when the red light tells you.
Because it’s portable and light (1.1kg) with a 1.7m cable, it’s easier to reposition than bulkier dehumidifiers—particularly if you’re trying to manage different rooms at different times.
Is it worth it?
A solid pick if you want a quiet, energy-efficient mini dehumidifier for smaller spaces, and you’re mainly targeting damp and moisture build-up in rooms like bathrooms, kitchens, bedrooms, cupboards, or similar areas.
It may not suit you if your rooms are often below 15°C or don’t reach the humidity levels the product recommends, or if you need a high-capacity solution for large, consistently damp areas.
If you’re the sort of buyer who prefers practicality—easy tank emptying, an auto shut-off for peace of mind, and the ability to place the unit close to where moisture happens—this one aligns nicely with that approach. Just don’t expect it to replace ventilation or address ongoing water ingress problems.
