Top 5 Best Dehumidifiers for the Bathroom in 2019: Buying Guide
You’ve probably heard about room humidifiers – the appliances used to introduce greater levels of humidity in certain rooms in your home. However, as extreme dryness can cause health problems, too much moisture can also create some pretty nasty health problems if left untreated.
Dehumidifiers work by eliminating excess moisture from a room. The ideal relative humidity (RH) level for any home is between 40% and 50%. As the temperature drops, it’s recommended that you keep the RH level in your home as close to 40% as possible to avoid condensation buildup on your windows.
How Does a Dehumidifier Work?
If you’ve ever seen a buildup of condensation on a glass containing a cold liquid, then you’re already familiar with how a dehumidifier works. Essentially, the coils inside a dehumidifier are a lower temperature than the surrounding air, causing the air to cool down and lose its ability to retain moisture. The result is droplets of water that form around the coils and drop into a basin or bucket for disposal.
As the air exits the machine, it will pass over the dehumidifier’s warm motor, giving it a slightly hotter temperature, thus making it attract moisture to it like a magnet. The air will then re-enter the machine, and the process will begin anew.
Why Do Bathrooms Need a Dehumidifier?
Any room that’s exposed to extreme moisture – e.g., basements, laundry rooms, bathrooms – should have a dehumidifier. Mold, mildew, and bacteria flourish in moist environments. Not only can they wreak havoc on your home and its value, but inhaling these substances, even in small quantities, be potentially dangerous to your health.
The bathroom is one of the consistently dampest environments in a home due to running water in such a tight, enclosed space. There’s no way you can eliminate moisture from the bathroom other than leaving the door wide open or cracking the bathroom window. However, you might just be introducing a host of new problems if you plan on leaving the window open during the cold months.
Bathroom Dehumidifier Buying Guide
Many bathrooms come with built-in fan vents to reduce the buildup of mold and mildew, but you may find this system to be ineffective. If your bathrooms remain damp or wet throughout the year, you may want to consider investing in a dehumidifier.
However, there are numerous models out there that might make the buying process a tad bit confusing. In this section, we’ll provide you with a list of the most crucial specs and features to consider when looking at potential bathroom dehumidifiers for your home.
Dehumidifiers can be separated into different categories based on how large a room they can handle. They are large-capacity, medium-capacity, small-capacity, and whole-house capacity. You don’t need a whole-house model set up in your bathroom.
However, depending on how extravagant your bathroom is, as well as how much moisture accumulates in your bathroom per day, you may need to purchase a bigger model. Most houses can get away with a small-capacity dehumidifier.
Humidifiers are machines that usually need to be run continuously in damp rooms, your bathroom included. We’re lucky that with today’s level of technology, most dehumidifier models can run extremely efficiently, saving you tons of money on utility bills in the long run.
However, you also need to be aware of the capacity at which the dehumidifier operates since larger models consume more energy than small-capacity dehumidifiers.
One of the biggest pains in the neck is having to manually dispose of the accumulated water that drips down into an awaiting drip pan. There are still models that use this type of water-removal system. More modern methods of eliminating water include on-board buckets and drain hoses.
On-board buckets are similar to drip pans, but you don’t need to worry about the bucket overflowing. Models that come with these buckets have a feature which shuts the motor off and warns the owner that it’s time to empty the bucket. This requires a bit of babysitting and having to dispose of the collected water manually. This also means more energy consumption, especially in extremely wet bathrooms, since the motor will continuously turn off and needs to be turned back on periodically.
Drain hoses are the more convenient method of getting rid of the accumulated water. You simply need to connect the drain hose into the drain port and place the other end of the hose out the window or in your bathroom sink. Although this is the worry-free way of getting rid of water, it can also be a bit of an eyesore if the hose doesn’t run outside of a window.
A humidistat is a humidity gauge which detects the RH level in a room. When the humidity hits a certain point, depending on the dehumidifier, it’ll automatically kick-start the machine to life to bring the RH to a more tolerable level.
This is an excellent feature to have, especially if you don’t want your dehumidifier running 24/7, but it can also be a bit expensive since you need to surge the appliance every time the gauge detects excessive humidity.
There is a range of special features that can improve the overall experience of running a humidifier. Some of these features include user-friendly control panels, frost sensors to prevent an icy buildup around the coils, washable and reusable air filters, and auto-restart (paired with humidistat).
A bathroom absolutely needs a dehumidifier if your fan vent system isn’t sufficient. The extreme moisture that originates from steamy showers, flushing toilets, and running faucets could potentially, if not dealt with, lead to the growth of mold, mildew, and other unsightly splotches on your bathroom walls, tiles, and tubs.
There are several types of dehumidifiers, but for the standard-sized bathroom, a small-capacity dehumidifier will be just fine. Apart from knowing how large a room the dehumidifier can handle, you should also pay attention to how much energy it uses, how to get rid of the accumulated water, whether it comes with a humidistat, and whether there are other special features included in the unit.
