Best Dehumidifiers: 14 Favourites to Beat Damp and Cut Bills 2026

Finding the best dehumidifiers can transform your home, protecting your health and slashing energy bills. With 14 top models tested, we reveal the ultimate choices for beating damp.

You don’t have to live in the American deep south to feel the effects of humidity. At home, just breathing makes the air more humid, let alone cooking or showering. And when it gets too humid, it’s bad for our health as well as our homes. In fact, the two are connected: humidity lets mould and dust mites flourish – and they, in turn, can trigger asthma and allergies.

Dehumidifiers can make your indoor environment more comfortable by reducing the amount of moisture in the air. Because of this, they’re also a great laundry-drying hack. I use mine to dry clothes fast, and for a fraction of the cost of tumble drying. Not sure if you need one? You can buy a hygrometer cheaply – the one I used for testing cost less than £10 – to check your home’s relative humidity and make an informed decision.

Why You Need a Dehumidifier

Excess moisture in your home can lead to a host of problems, from respiratory issues to structural damage. The best dehumidifiers tackle these issues head-on, creating a healthier living environment. They work by drawing in humid air, cooling it to condense the moisture, and then reheating it to release dry air back into the room.

Beyond health benefits, dehumidifiers can also save you money. By reducing the need for tumble drying, you cut down on electricity usage. Additionally, maintaining optimal humidity levels can improve the efficiency of your heating system, as dry air feels warmer than damp air.

Key Features to Consider

When shopping for a dehumidifier, consider the tank capacity, extraction rate, and energy consumption. Larger tanks mean less frequent emptying, while higher extraction rates are better for larger spaces. Energy efficiency is crucial for keeping running costs low.

Noise level is another important factor, especially if you plan to use it in a bedroom or living area. Some models come with additional features like humidistats, timers, and auto-defrost, which add convenience.

Top 14 Dehumidifiers Comparison

Our testing process involved measuring extraction rates, energy usage, and noise levels in real-home conditions. Here’s a snapshot of how the top contenders compare:

How We Tested

I’m an award-winning consumer technology journalist with decades of experience testing electrical appliances; I’ve been reviewing gadgets for almost 30 years. I live in a terrace house with a lovely number of children and far too many pets, so there’s lots of laundry: I use a dehumidifier to dry clothes.

Each dehumidifier was tested over several weeks in a typical home environment. We measured the amount of water extracted in a set time, the energy consumed, and the noise produced. We also evaluated ease of use, including tank emptying and filter cleaning.

Our testing revealed that more expensive models don’t always guarantee better performance. Some budget-friendly options performed admirably, while a few premium models were surprisingly inefficient.

Key Takeaways

• Health benefits: Reducing humidity prevents mould and dust mites, easing asthma and allergies.
• Cost savings: Dehumidifiers can dry clothes cheaply and improve heating efficiency.
• Variety: Options range from compact 7.5-pint units to high-capacity 20-pint models.
• Features: Look for humidistats, timers, and auto-defrost for convenience.
• Noise: Quieter models (under 40 dB) are better for bedrooms.

FAQ

What size dehumidifier do I need?

For a small room (up to 500 sq ft), a 10- to 12-pint dehumidifier is sufficient. For larger areas or very damp conditions, choose a 20-pint model or higher. Consider the extraction rate and tank capacity to match your needs.

How much does it cost to run a dehumidifier?

Running costs depend on wattage and usage. A typical 300-watt dehumidifier used for 8 hours a day might cost around £0.50 per day, based on average UK electricity rates. Energy-efficient models can cost less.

Can a dehumidifier replace a tumble dryer?

Yes, many people use dehumidifiers to dry clothes indoors. They are far cheaper to run than tumble dryers and gentler on fabrics. Place clothes on a rack in a small room with the dehumidifier running for best results.
