Pro Breeze Dehumidifier Review

Pro Breeze’s dehumidifier is the best dehumidifier for a conservatory because it can remove 20 litres of moisture per day, has a large water storage tank, and an easy-read digital LED display.

This conservatory dehumidifier is one of the biggest in terms of its extraction rate. It removes a massive 20 litres per day which drips into the 5.5 litre storage tank. The tank has an auto switch off or a continuous drainage hose if you want to leave it running for longer.

A digital LED display shows the current humidity level in your home and you can set its auto humidity level as you please between 30% and 80%. It also has four modes including auto defrost, child lock, fan only and laundry mode.

With a 24-hour timer and wheeled base this is the best dehumidifier to remove condensation in a conservatory. It is safe, has lots of useful features, and a big moisture removal capacity.

EcoAir DC18 Compact Portable Dehumidifier Review

Ecoair’s compact dehumidifier is one of the best machines to remove condensation in a conservatory because it’s compact, portable, and quiet

Despite its compact size, it can still pull 18 litres of moisture from the air every day to its 3.5 litre tank or continuous drainage pipe.

Designed to fit in smaller spaces this small dehumidifier has easy-glide caster wheels so you don’t accidentally spill water everywhere on the move, a washable air filter, and two fan speeds to reduce energy consumption.

The electronic control panel allows you to easily understand the humidity level, and set the timer and auto defrost modes.

Reviewers say this is a very quiet model so it’s one to consider if you are at home all day.

Dimplex DXDH16N Dehumidifier Review

Dimplex has made a really great conservatory dehumidifier at a bargain price. It’ll extract 16 litres of water a day and has a 2.3 litre tank with an indicator to show you when it’s getting full.

Dimplex dehumidifier is suitable for domestic rooms measuring 24 metres squared which is more than enough for a standard UK conservatory.

It has easy-glide castors to avoid that whoosh of water that soaks your slippers, and a washable filter to keep everything clean.

The auto shut off feature gives you peace of mind as it’ll turn off once the storage tank is full, and the adjustable humidistat lets you keep an eye on how your humidity levels are faring.

I’ll be honest, this is my favourite in terms of style. Its slender body and unobtrusive colour mean it’ll blend into any décor so you barely notice it.

Meaco MeacoDry Dehumidifier Review

Meaco’s MeacoDry is another very quiet conservatory dehumidifier at a tiny 35 decibels and because it’s compact it’s energy-efficient too.

Despite its small size this still quietly pulls out condensation in a conservatory at a max rate of 10 litres per day. Just right for drying the laundry and keeping the conservatory free from damp.

In fact, it has a specific laundry mode, along with a defrost mode, an auto timer to schedule when it turns on and off, and an automatic shut off for safety.

It’s lightweight too and easy to move around the home or into the garage or caravan if you’ve mould problems there as well.

This is a good choice if you only need a small dehumidifier or you’ve not a lot of space to keep it in.

VonHaus 2 in 1 Dehumidifier and Air Purifier Review

Vonhaus’s 2 in 1 dehumidifier and air purifier is one of the best dehumidifiers for a conservatory because it pulls a whacking 20 litres of moisture from the air in spaces up to 35 metres squared. That’s plenty for a conservatory and often the whole ground floor space of many modern townhouses.

It has a multifunctional control panel with a purifying setting, a 24-hour timer, adjustable humidity options, defrost mode, and drying or quiet modes on a LED display.

It has an automatic shut off for safety or a continuous overflow pipe for really damp areas.

I like the LED lights that indicate the humidity levels without complication. A red light means it’s above 70%, a green light 50-70% and orange is below 50%.

This is a great dehumidifier for the conservatory, especially if it’s really damp in there and you’re struggling with mould.

Conservatory Dehumidifier Buyers Guide

What Is ‘Litres Per Day Capacity’

Litres per day capacity is an important consideration when you’re buying a dehumidifier. It refers to the amount of water the machine can extract from the air.

When brands talk about the size of their machines, such as 20L, they’re referring to its litre capacity rather than the tank size.

If you only want to dehumidify one small room you can go with a small litre model like the Meaco MeacoDry Dehumidifier, if you want to dry the whole house a large one like the VonHaus 2 in 1 Dehumidifier is best.

In general, 45 square metres will need 6.5 litres per day capacity and 225 square metres needs 18 litres.

Does Water Tank Size Matter?

Water tanks store the extracted water. If you don’t want to empty it frequently go large or look for a continuous drainage pipe like the Pro Breeze’s dehumidifier’s pipe that’ll reach into a sink or through the window.

How About The Display?

Displays have really moved on in the past few years. An LCD display is helpful as it’ll show you what your dehumidifier is achieving.

Look for a humidity sensor, mode settings, auto shut off – all of these aspects highlighted in nice bright LEDs makes life a bit easier.

What Is A Humidity Sensor?

A humidity sensor like EcoAir DC18 portable dehumidifier’s sensor monitors how much moisture is in the air. The more expensive machines adjust to match the level of humidity you’ve selected, such as 50%.

It’s not essential by any means but it does stop you having to check and adjust the setting manually.

Auto Timer Shut off

Another nice to have feature is an automatic timer shut off just like the one in Dimplex DXDH16N Dehumidifier.

Programming your dehumidifier saves money in the long run as it’ll turn off when it reaches your required humidity level rather than whirring away and burning up power.

FAQs

How to get rid of condensation and mould in your conservatory?

Mould loves a damp environment. It grows quickly when moisture collects on cold surfaces such as glass and outward-facing walls. Conservatories are particularly at risk of condensation and mould because the temperature varies so much.

You should open the windows as often as possible to let in circulating air to dry up condensation, and mould build-ups can be dealt with by commercial sprays, but if this is difficult and mould keeps returning then a dehumidifier can help extract moisture from the air before it turns into condensation and mould. 

How does a dehumidifier work? 

Dehumidifiers work by collecting the excess moisture from the air preventing it from turning into condensation and mould. Moisture is stored in a water tank ready for disposal.

There are two types: 

Refrigerant (or compressor) dehumidifiers draw in air which condenses on a cold coil and drips into a storage tank. They are recommended for hotter environments such as a family home that’s occupied all day.

Desiccant dehumidifiers use an absorbent material to soak moisture from the air which is then heated so it drips into the water storage tank, These are recommended for lower temperature environments like an unheated conservatory.

How long should you leave a dehumidifier on for? 

There is no standard limit but it’s best not to leave it 24/7.

Some of the more expensive dehumidifiers have a humidity sensor which is sometimes called a ‘humidistat’ that’ll tell you how much moisture is in the air.

Most people aim for 50% so you can leave your machine on until this level is reached, but check the user manual for a maximum time limit. 

How much does it cost to run a dehumidifier?

 These days dehumidifiers don’t cost a lot to run, and you can buy energy-efficient models to keep your bills down.

Which? say that a 250W dehumidifier running for four hours a day costs £19.50 a year on average, but it’ll all depend on your power costs. Check and swap to a lower gas and electricity rate if you haven’t already!

Slower machines take longer to extract moisture so their energy costs are higher – but they cost less in the first place so it’s swings and roundabouts there!

The good news is that dehumidifiers warm up your home so you’ll save on heating costs whatever model you buy.
