What To Look For (Buyer’s Guide)

Choosing the best bathroom dehumidifier is very straightforward despite the many choices in the market. A good dehumidifier can remove excessive moisture in a bathroom and maintain a healthy humidity level. To avoid picking the wrong model, The buying guide below will focus on the key points you should consider when buying a dehumidifier.

  • Dimension - Size matters even for a small dehumidifier. As the bathroom is one of the smallest rooms in the house, placement can be an issue for a bigger unit. There is limited space left on the bathroom vanity with toothbrushes, toothpaste, hand wash, and soap occupying a large chunk of the area.
  • Design and usability - Pick a model that blends well with your bathroom decor as you will be staring at it for years to come. Waterproofing is not a necessity, the portable layout must be able to withstand water splash and will not impede the airflow in tight spaces.
  • Moisture capacity - Look for a thermoelectric dehumidifier with a moisture output of at least 9 ounces and 1,100 of cubic feet coverage. It will cater to U.S. average-sized bathrooms at less than 40 square feet for a small home or apartment. The running duration will heavily depend on the moisture range, the size of your bathroom, and the relative humidity level.
  • Reservoir size - The bigger the reservoir capacity, the more water can be collected. If your bathroom condensation level is very humid, go with a larger reservoir size will reduce the frequency of having to empty the water.
  • Auto shut-off - Very convenient and important feature in a petite dehumidifier. Once the reservoir is full, the dehumidifier will automatically switch off to prevent an overflow. Stay away from models that do not have this basic feature.
  • Pricing and budget - Because bathroom dehumidifiers are typically smaller in size, you can easily purchase one under $100 while an entry-level model will not cost more than 40. Bear in mind that cheaper models tend to have some trade-offs. So set your budget, compare the specification, and squeeze the best possible deal you could find.
  • Noise level - Bathroom dehumidifiers powered by Peltier technology have a low noise output. Since you're unlikely to stay in a bathroom for long, it will no cause any disturbance when you're trying to wash up.
  • Power consumption - Thermoelectric dehumidifiers used in the bathroom have a low wattage output given their small size and limited capacity. That said, newer models with Energy Star ratings tend to be more energy-efficient than older ones. Unless you are going for a bigger model, it will not cause a concern on your utility bill.

The first bathroom dehumidifier needs no introduction. Ivation IVADM35 is featured on many people's bucket lists for a good reason. It is silent, effective, and still comes in a portable petite size despite the slight increase in dimension. You can effortlessly move it around the bathroom or place it on a countertop basin with plenty of space left for your skincare products. Thanks to the sturdy 4 rubber feet, Ivation IVADM35 will not topple over easily and spill water all over the place.

Minimum maintenance is exactly how a petite dehumidifier should be. The classic thermoelectric design comes with a single button control with 2 LED indicators. Just turn it on and let the dehumidifier work on its own. The only thing you need to pay close attention is the yellow LED indicator that lights up once the reservoir is full. Simply pour away the collected water into the basin and Ivation IVADM35 will resume back operation. The larger 68 oz water tank means you only need to empty the water every 2-4 days depending on how damp the bathroom is. The rest of the specification is standard across all thermoelectric dehumidifiers including the 1-year warranty that covers all manufacturer defects.

Being a higher series, Ivation IVADM35 thermoelectric dehumidifier has a much stronger moisture absorbent than most models here. The advanced Peltier technology can capture 20 ounces of moisture up to 2,200 cubic feet. Twice as much as an entry-level bathroom dehumidifier. This is done through the conversion of a temperature differential into electricity. Damp air pulled in will be condensed into droplets for the bucket to collect, and dry air will be dispersed out as mist. As Peltier technology has no moving parts and compressor other than the cold heat module, the entire dehumidification is whisper quiet. Great for smelly bathroom that has mold and mildew growing all over the place.

There is one deal-breaker that can hold people back on this purchase. Ivation IVADM35 Thermo-Electric Dehumidifier is expensive for its segment. In fact, it is 3 times more expensive than other small bathroom dehumidifiers listed here. Other than that, IVADM35 is also slightly larger than the typical petite dehumidifiers but it is not very noticeable. If you can splurge the extra 20-30 dollars, there is no doubt Ivation IVADM35 would be an ideal bathroom dehumidifier.

Bottom line: A powerful but expensive mid-size thermoelectric dehumidifier. Go with this if you value performance and versatility over cost.

Break free of the monotonous option. Ivation IVADM45 is the most unconventional thermoelectric dehumidifier on the list. In fact, it is a hybrid between a full-fledged and a mini model. The well-built, modernized shape of 8.6 x 13.8 x 7 inches looks nothing like the rest, especially with the front digital display. The back design is a big contrast to the front with a classic air vent and a bottom removable water reservoir. With IVADM45, we found ourselves relying on the auto-shutoff feature regularly as it can be tricky to monitor the water level without rotating the dehumidifier. That's just the way it is.

Unlike other thermoelectric dehumidifiers that will run nonstop and waste a lot of energy, Ivation IVADM45 comes with a convenient auto humidistat function that allows you to set your desired RH level in the range of 40% to 80%. Ivation IVADM45 will automatically turn itself on when the relative humidity level is higher than the set value and automatically turn off once the humidity level falls lower than the set value. The only thing you need to do is preset the desired humidity point and empty the large 68 ounces water reservoir every 2 to 3 days. Easy peasy lemon squeezy.

There are not many thermoelectric dehumidifiers that come with auto humidistat, Ivation IVADM45 is the rare exception. The advanced Peltier technology creates 2 vary temperatures that generate electricity while electricity does the opposite. This phenomenal Peltier effect will continue to remove moisture in the air even after you're long done with your hot shower. As such, Ivation IVADM45 will silently remove 25 ounces of water a day with up to 2,200 cubic feet (cap at 86° Fahrenheit and 80% relative humidity). Great at controlling large bathroom dampness and help towels dry faster. It will also halt mold and mildew growth to a certain extent.

There are a lot of things you like about Ivation IVADM45 such as the strong moisture absorbent and massive water tank. However, you will have to account for the higher price tag where you could substitute it with 2 mini petite dehumidifiers instead. IVADM45 is also not suitable for washroom countertop use due to its size. It will eat up a lot of the table space and the tall height could obstruct the bathroom mirror view. As mentioned earlier, We're not a big fan of the water reservoir located at the back but that is just nitpicking at this stage. If you are not placing it on the countertop, Ivation IVADM45 would be the best bathroom thermoelectric dehumidifier you can get your hands on.

Bottom line: This is the only mid-size thermo-electric dehumidifier with auto humidistats. Suitable for bathroom use if you don't mind the slightly bulky size.

What To Do If A Bathroom Doesn't Have A Fan Or Windows?

Steaming showers or hot baths can quickly increase a bathroom dampness level and lead to condensation issues. Below are ways you can dehumidify a small bathroom that doesn't have a fan or windows.

  • Get a portable dehumidifier as it is the best way to remove moisture in a windowless bathroom.
  • Install a bathroom extractor fan or heater to help with damp air circulation.

  • Charcoal, baking soda, desiccant, and indoor plants do help with the dampness but the impact is minimal.
  • Use a dry cloth and wipe away water droplets from condensation.
  • Keep the bathroom clean and clutter-free to prevent moisture, mold, and bacteria build-up.
  • Increase your home temperature by turning up the thermostat.
  • Take a shorter, cooler shower instead.
