Best Wall-Mounted Dehumidifiers

According to the annual climate report of 2020 by the National Oceanic and Atmospheric Administration (NOAA), land and ocean temperatures have increased by 0.13 degrees Fahrenheit every decade since 1880

The increase in temperature directly increases gaseous water vapor from water bodies, also known as humidity. The warmer air holds more water vapor or humidity as well.

Due to the drastic increase in humidity in many parts of the world, dehumidifiers have become almost a necessity. Dehumidifiers decrease humidity of an overly humid indoor space and halt the growth of mold, allergens, and mildew found in damp and humid atmospheres.

Buyer’s Guide For The Best Wall-Mounted Dehumidifiers

Covered Area

When buying any dehumidifier, you should consider the floor area of the room in which you want to put the dehumidifier. Just like air conditioners, dehumidifiers also have a specific area in which they operate properly. If the floor area exceeds that, then the dehumidifier won’t be as effective in its performance.

Capacity 

The capacity of a dehumidifier or an AC with dehumidifier is measured according to the amount of water it drains each hour or day. The capacity will also depend on the area the dehumidifier covers. For example, a 1,200-1,500 square feet dehumidifier should have at least 25 pints per day capacity.

Silent

Many dehumidifiers make a lot of noise, which can be a big issue for most people, even if the dehumidifier does a great job maintaining humidity. If the dehumidifier is being used for commercial use, then you may tolerate slight noise, but that’s not acceptable if you install it in your home. Make sure to read the customer reviews entirely before buying, as many dehumidifier brands lie about the sound.

Installation

Installing a dehumidifier or an air conditioner with a dehumidifier can be a tricky job, especially if you are not too used to handling electrical appliances. If you are not planning to call an electrician to install your wall-mounted dehumidifier, then go for the ones that are the easiest to install.

Drainage

Dehumidifiers ought to drain a lot of water, therefore it would be a great added advantage to have an automatic drainage system in your wall-mounted dehumidifier. Note however that very few wall-mounted dehumidifiers have hands-free drainage systems and those dehumidifiers are usually very expensive. Therefore, having this feature will depend on your budget.

Energy

Buying a dehumidifier is a long-term investment, and you don’t want it to be a big burden on your electric bill. Therefore do holistic research to find the most economical and energy-saving wall-mounted dehumidifier. Note that the products in this article are all energy efficient.

Durability

Dehumidifiers are not something that you should be buying every season as it should be a long-term investment. It’s essential to always buy a durable product whenever you are paying this much for a device.

Cooling

The reason I put cooling as the last feature in the buying guide is that it’s not a mandatory feature. However, many wall-mounted dehumidifiers are 2-in-1 units that both cool and dehumidify, so if you are opting for an air conditioner with dehumidifier, you will want to consider its cooling power too.

Frequently Asked Questions

Which is the best wall-mounted dehumidifier for you?

There is a limited selection of effective wall-mounted dehumidifiers available in the market. In pursuit of writing this article, I have gone through each of them, and I can conclude that the Innovative Dehumidifier Systems IW25-4 is the best dehumidifier you can find currently.

Why should you buy a wall-mounted dehumidifier?

The primary reason behind buying a wall-mounted dehumidifier is that it saves a lot of space, especially if you’re planning to buy a large dehumidifier. Wall-mounted dehumidifiers take up a lot less space and no floor space.

Will a dehumidifier kill mold?

Dehumidifiers do not kill mold, but they prevent mold growth by cutting out the main cause for growth, which is humidity — the lesser the humidity, the lower the chances of mold in your home or basement.

What is the best humidity setting for a dehumidifier?

The settings on any dehumidifier can vary depending on the manufacturer or the brand. But what matters the most is the humidity levels you set on your dehumidifier. The humidity inside your home should always be between 30 to 50 percent. If the humidity percentage goes higher than 60 percent in any instance, the chances of developing molds and allergens become much higher.

Will a dehumidifier stop condensation on walls?

Dehumidifiers are pretty effective in removing humidity, and as a result, they also prevent condensation on walls and prevent them from becoming damp. 

How much humidity can a dehumidifier remove?

It depends largely on the type of dehumidifier and its capacity. Usually, a humidifier will remove humidity with 30 to 40 percent of its capacity rating. Ideally, a decent size humidifier removes around 3-4 liters of water every day.

Should you open windows when using a dehumidifier?

Opening your windows when there’s too much humidity inside can be really helpful as the air circulation reduces the stickiness produced by humidity. But if you’re using a dehumidifier, then I would strongly suggest not to open your windows. It will allow the outside moisture to come in, counteracting the purpose of the dehumidifier.

Parting Words

Dehumidifiers are among the most highly bought seasonal electric appliances. They have proved to be relatively effective in controlling humidity in your home. Dehumidifiers also prevent the growth of allergens and mold by controlling the humidity levels. A notable issue with dehumidifiers and the focus of this article is the amount of space they take up, hence justifying preference for wall-mounted dehumidifiers, which barely take any place inside your home.

In this article, we covered the top four wall-mounted dehumidifiers and air conditioners with dehumidifiers that are available in the market. Make sure to go through the entire buyers guide before you make a choice to buy any wall-mounted dehumidifier.

I hope this article will help you with choosing your new wall-mounted dehumidifier so that you can finally say goodbye to those sticky and irritating humid days (at least in your home).
