Best Dehumidifiers for Dust Mites and Allergies

1

Updated: December 5, 2018

If you suffer from allergies or have a house filled with dust mites, you’ve likely been advised to get a dehumidifier.

Dust mites increase in population when the relative humidity is more than 50% and decrease in population when the relative humidity is below 50%.

Humidity control is a decisive factor for dust mites population growth.

Will a dehumidifier help with allergies?

Are you wondering if a dehumidifier can really work to get rid of dust mites and help allergies? The science says that they can.

One study showed that using a dehumidifier did indeed reduce the number of house dust mites.

While the dehumidifier group in the study didn’t see a drastic reduction in allergens as well as house dust mite count, the authors of the study admit that it was limited in terms of size and the dehumidifiers used.

Another study assessed whether or not a dehumidifier could help with asthma. The study was followed up by another study that showed dehumidifiers were able to create a significant improvement in evening peak flow.

Finally, there was a study assessing whether dehumidifiers can control allergens and dust mite population. It showed that dehumidifiers can get the job done, but one portable dehumidifier isn’t enough to keep an entire house clean of dust mites.

With all of this in mind, let’s take a look at the 5 best dehumidifiers for dust mites and allergies.

What to Consider when Choosing a Dehumidifier

Size of your space

As one of the studies mentioned above showed, a small dehumidifier isn’t effective at clearing an entire house. A smaller one will do fine for a single room, but you need to consider getting a bigger one if you’re looking to cover more room.

Choose a dehumidifier based on the size of the space you need to dehumidify. Check the product description to find out how much space they can handle.

Water tank Capacity

The capacity of the dehumidifier is also another thing to consider. A larger capacity dehumidifier needs to be emptied less, but it does cost more.

Cost vs Efficiency

Buying the most expensive model there is might not always be the best choice. Buying a dehumidifier for every room in the house is also not very cost-effective either.

Consider the cost-effectiveness of your purchase. If you’re looking to buy a dehumidifier for one or two rooms, then go with a good unit for that size room.

If you’re looking to dehumidify your whole house, then just go for a whole-house dehumidifier that can keep every room free from moisture.

Moisture and Temperature Levels

A dehumidifier is used to remove humidity, which it does by eliminating moisture. The more moisture you need to remove, the more powerful the humidifier you need to do it.

If you don’t mind splashing your cash, then consider a commercial dehumidifier or a specialty machine designed for a specific space such as a basement or crawlspace.

Temperature levels are also important when it comes to using a dehumidifier because temperatures can affect the operating ability of the machine.

Dehumidifiers are less effective when placed in low-temperature areas, such as a basement or garage. If you need to dehumidify a cold room, then you need to find a dehumidifier that won’t freeze up on you.

Special Features

Some humidifiers come with their own special features. One of the most useful of these features is ducting. A dehumidifier with ducting can dehumidify several rooms at once and can be hidden in a closet to save space.

You can also get dehumidifiers with digital/remote controls, timers, and condensate pumps, among other features. Ask yourself if you really need that additional extra, and avoid paying for things you don’t want/need.

Noise and Power Consumption

Some dehumidifiers are known to make an awful lot of noise. Some of them also consume a lot of power. The two problems tend to go hand in hand as the more power a unit consumes, the louder it is.

The thing about dehumidifiers is those small and portable models designed to quickly remove moisture are the ones that consume the most power and make the most noise.

If you want to use your humidifier a lot then you want to consider getting a whole-house humidifier. These fit into the air conditioning system, meaning they make almost no noise.

There are also a wide range of whisper-quiet dehumidifier models that boast effectiveness without making a lot of noise.

Conclusion

One thing our list has shown is that there really is a lot of choice when it comes to finding a high quality dehumidifier. There’s almost a little too much choice when you think about it!

If I had to choose just one of these dehumidifiers I think I would go with the Keystone KSTAD508. It has more going for it than the mini dehumidifiers, has the same capacity as the FAD504DWD, but is much smaller and cheaper.

It’s not the perfect choice of course, but it does just what I need it to do. That’s the thing you need to remember when it comes to choosing a dehumidifier; find the best one for you. Read through the reviews of the different dehumidifiers and pick one that matches your needs and budget.
