Who knew that the air you breathe in your home could be harmful to you? According to the Environmental Protection Agency (EPA), indoor air quality is one of the top environmental health threats. One of the factors that affect healthy air is humidity which must be less than 50% relative humidity. When you have low relative humidity, you are helping prevent dust mite infestations, the growth of mold and mildew, and even bacteria growth. Plus, it lessens the out-gassing of VOCs. Naturally, to be able to control the level of moisture inside your home, you’ll need one of the best dehumidifiers. Based on our research, the list below contains the 10 best models in the market today.

2. Eva-dry E-333 Renewable Mini DehumidifierBest Dehumidifier for Gun Safe
This mini dehumidifier isn’t like your average device. It uses renewable silica gel technology which absorbs moisture in an enclosed room that has a maximum area of 10’x 10′. The silica gel is 100% renewable and does not require any electricity or batteries to start adsorbing moisture. An indicator window turns blue when the silica gel has adsorbed 8 to 10 ounces of moisture which means you need to plug the unit in order to “renew” it. Because it uses odorless and non-toxic silica gel, this dehumidifier is child and pet-safe. However, depending on your location, the unit does not seem to last as promised (20 to 30 days) before “recharging.” It typically only lasts a week. It also seems to get a bit hot when charging. In addition, the unit doesn’t last for more than a couple of years.

Best Dehumidifiers Buying Guide
Dehumidifiers probably aren’t on your list of must-haves inside your home. But if you value your health and that of your family members, you’re going to need one. There are plenty of benefits to owning a dehumidifier, the least of which is mold prevention. The right dehumidifier can also improve the indoor air quality of your home, eliminate dust mites, prevent bacterial growth, and even protect the structure of your home. Of course, all of that presupposes that you buy the right dehumidifier. If you’re already thinking about buying one, then you need to know more about how these things work and what features you should be considering. Our buying guide should do all that and more.
So, how does a dehumidifier work?
Humidity is the amount of moisture that is present in the air. And according to studies, a high level of humidity in the air can cause adverse health effects. This means that to ensure your indoor humidity is at the optimum level, you’ll need to take away that extra moisture in the air. A dehumidifier sucks in the air from the room and removes the moisture by cooling the air and turning the moisture into liquid water. That water drips into a tank and the air is then warmed back up by a heating element before getting blown back into the room.
How big should your humidifier be?
Dehumidifiers come in various sizes which is based on pint capacity – how much moisture it can remove from the air per day. You should choose a dehumidifier that fits the size of the area that you want to dehumidify.
Dehumidifiers in this category like the Eva-dry E-333 Renewable Mini-Dehumidifier can remove around 8 to 25 ounces of moisture in 24 hours. This is ideal for small spaces only such as a bathroom or crawlspace.
These can remove 20 to 35 pints of moisture per day which makes them ideal for small spaces that are damp but not wet such as a laundry room. The Pure Enrichment Deluxe Mini Dehumidifier is a good option if you want to adequately cover a room as big as 150-square feet.
These can remove up to 50 pints of moisture in 24 hours. You can use these models to dehumidify medium to large spaces that are only a little damp.
Models in this category such as the HomeLabs 70-Pint Dehumidifier can suck up to 70 pints of moisture per day which makes them ideal for large, wet spaces.
These are either portable units or models that can be added to your centralized heating system. They can handle large areas as big as 3000 square feet.
What kind of controls does it have?
Dehumidifiers come with two types of controls – a dial and digital controls. A dial provides you basic control, enabling you to set the humidity according to preset levels which are normal, dry, and very dry. Digital controls like what you find with the Honeywell Energy Star DH70W lets you set the humidity level more precisely – according to your preferred humidity level based on percentage numbers. Some models feature a built-in hygrometer that will measure the level of humidity inside your home so you can know when to turn your dehumidifier on and off.
Consider the tank size
Tank size or water capacity tells you how much water the dehumidifier can hold before you need to empty it. This is usually measured as cubic feet per minute (CFM). The bigger the CFM number, the higher the capacity of the tank. And the bigger the tank, the less frequently you’ll be emptying it out. However, you should also take note that the bigger the tank, the higher the cost. Also, this will make the dehumidifier heavier and more difficult to empty out. You might want to get a dehumidifier with a front-loading bucket to make emptying it out easier like the Frigidaire FFAD7033R1. Some models feature a drain-hose connection that allows you to divert any water collected by the dehumidifier to go directly down the drain such as a basement floor drain or laundry sink. Other models feature evaporation technology and a heat pump that enables the device to also function as an air conditioner.
Does it have an auto-defrost feature?
If you live in a cold climate, you’re going to need a dehumidifier that can operate in temperatures as low as 41°F. Once your indoor temperature goes below 65°F, the heat-exchange coils inside a dehumidifier will frost over. Your dehumidifier should be Energy Star certified to 45 to 40 degrees like the Ivation 70 Pint Energy Star Dehumidifier. Take note that an auto-defrost feature will cost more but it does help you save money that you’d otherwise spend replacing frozen coils.
How noisy is the dehumidifier?
Dehumidifiers are not quiet appliances. Medium and large-capacity models have a noise level of 55 to 67 decibels. Smaller models are, naturally, quieter but can still disturb your sleep at night if the dehumidifier is located inside the bedroom. It’s best to test a unit’s noise level before making your purchase.
What other features should you consider?
Dehumidifiers with this feature enable you to schedule when the unit will turn on. This is particularly useful if you want the unit to switch on at night or when you’re out of the house.
This feature enables the dehumidifier to start back up again after a power outage. This is a useful feature to have if you plan on using the dehumidifier while you’re out of the home and there’s a blackout.
This is an important feature because it automatically shuts down the dehumidifier once the tank has reached full capacity. In some models like the Pro Breeze, you’ll also find indicator lights that let you know when the tank is full.
Some dehumidifiers have filters that trap dust and dirt which prevents them from damaging the coils. With washable filters, you don’t need to replace the filters as often. The Keystone Electronic KSTAD70B, for example, comes with very easy-to-use filters.
Dehumidifiers that are Energy Star certified are guaranteed to use less energy but still run efficiently. This enables you to save money on electricity.
Some models come with casters which make them easier to move from one room to another. In addition, some units feature long power cords which allow you to place them wherever you want it.
