While one person’s definition of the best dehumidifier will differ from another person’s definition, I think it is probably safe to say that there are probably some features that should be common to all high quality dehumidifiers. Essential features that will ensure that the dehumidifier not only performs the job it is designed to do, but will do it without needing a whole lot of user input. Today, we are going to talk about some of these essential features of dehumidifiers and why they are important for you to consider before purchasing one.
The Water Reservoir
This feature can be found on most dehumidifiers. I am saying most because some use units don’t use a reservoir but either have a continuous drainage feature or uses some form of water absorbing material, such as silica gel, to collect water. We will talk about some of those a little bit later.
Dehumidifiers have reservoirs to collect the water that drip from the condensing coils when the moisture is extracted from the air. Therefore, you really can consider it as being an essential part of the whole dehumidifier. When buying a dehumidifier, it is important to get a dehumidifier with a decent size reservoir because you don’t want to have to empty it out more often than you really have to.
Continuous Drainage And Condensate Pumps
You will find continuous drainage on systems that don’t use a reservoir system, and its basic operation is fairly simple. What a continuous drainage system does is send the water down a hose so that it can exit the system via a floor or sink drain. As water is collected form the air, it is sent to the exit hose where gravity does its thing and carries it away from the unit.
Some dehumidifiers with a continuous drainage system also have a condensate pump that isn’t gravity based. Which means that it can pump the water upwards away from the system. This allows the drainage hose to be put into a sink drain or through a basement window.
If you look through dehumidifier reviews, then you’ll notice that a lot of dehumidifiers have an automatic defrost feature. All this feature does is to defrost the condensing coils if they freeze up because of lower than standard room temperatures. This allows the unit to be used in cooler environments—such as basements—that often fall below 42 degrees.
A humidistat is an essential feature in my opinion because it allows you to fine tune the humidity levels in your room. Units that don’t have one usually have to either run all of the time, or the user has to manually turn them on and off to keep humidity levels in their preferred range. Units that have a humidistat will automatically shut off when they have reached the minimum humidity level and turn back on when the humidity level gets too high. All without user input.
The above features are the ones that I consider essential on any dehumidifier. They not only allow the unit to operate more efficiently and effectively, but they also reduce the amount of time that you have to dedicate to setup and operation of the unit.
