But before buying one, it helps to understand how a dehumidifier works and why it’s so essential for UK homes. In this guide, we’ll explain the science behind dehumidifiers, where to use them, and why Newentor’s range of dehumidifiers is designed specifically for UK living.

What is a Dehumidifier?

A dehumidifier is an electric device designed to remove excess moisture from the air. When humidity builds up indoors, it can cause damage to walls, furniture, and even your health. A dehumidifier works to maintain a safe, comfortable indoor relative humidity level (typically 40–60%).

There are two main types of dehumidifiers:

• Compressor (Refrigerant) – Uses cooling coils to condense moisture from the air. Best for warmer spaces.

• Desiccant – Uses a moisture-absorbing material (desiccant) and works better in cooler conditions like garages and unheated rooms.

Newentor dehumidifiers use advanced smart humidity control to adjust performance according to real-time moisture levels—perfect for fluctuating UK climates.

How Does a Dehumidifier Work?

Let’s break it down step by step:

1. Air Intake
   The dehumidifier draws in moist air using a built-in fan.

2. Moisture Extraction

   • Compressor models cool the air inside the unit, causing moisture to condense into water droplets.

   • Desiccant models pass air over a moisture-absorbing wheel.

3. Water Collection
   The condensed water either collects in a tank or drains away via a hose.

4. Dry Air Release
   The dry air is reheated slightly and blown back into the room.

This continuous cycle removes litres of water per day, making it easier to control humidity in all parts of your home.

Where Should You Use a Dehumidifier?

Dehumidifiers are versatile and can be used in various areas of your home. Here’s how to match capacity and placement:

💡 Pro Tip: Use a hygrometer to check your room's humidity. The ideal range is 40–60% RH.

Why Dehumidifiers Are Essential in the UK

The UK's climate creates the perfect conditions for indoor damp:

• Frequent rainfall and cold weather limit ventilation.

• Older homes often lack proper insulation.

• Wet winters cause condensation on windows, especially in bedrooms and kitchens.

• Laundry drying indoors during wet months contributes to high indoor humidity.

A good dehumidifier combats these issues by:

• Preventing mould and mildew

• Reducing dust mites and allergens

• Protecting furniture, clothes, and paintwork

• Improving indoor comfort and warmth

• Lowering heating bills by reducing the "cold damp" effect
