How to Choose the Right Dehumidifier for Bathroom Without Vent

Knowing the top bathroom dehumidifiers on the market can give you a good idea of what to buy. But for you to choose the right unit for your space, you need to take a few key factors into account. 

Below are some crucial questions you must answer before you buy a dehumidifier

1. Is it the right size?

Dehumidifier for bathroom without vent

Basements and attics are usually large enough to accommodate any dehumidifier size. In contrast, smaller areas like bathrooms cannot afford the same flexibility. 

For your bathroom, you will want a compact model that fits easily in a corner or on a counter. A small form factor means the unit will not interfere with your movement. Small units are also easier to move around than larger, heavier models.

All our top picks are compact and light. Some, like the Eva Dry Wireless Mini dehumidifier, is less than a foot tall and only a few inches wide. 

2. Can it cover your bathroom?

The coverage of a dehumidifier is the largest size of space it can dehumidifier when performing at optimal levels. Manufacturers typically state the coverage as one of the specifications of a unit. So, before you start shopping for a dehumidifier for bathroom, measure the size of the space. 

Apart from size, the moisture level in your bathroom is a crucial consideration. For instance, if you often hang clothes indoors, you will need a more powerful dehumidifier relative to the size of the room. The same goes for houses located in areas that experience high humidity, such as the coast.

3. How large is the water tank?

Dehumidifier for bathroom without vent

Most users want to achieve the right moisture level with as little effort as possible. The larger the water tank, the more water a dehumidifier can hold. Hence the fewer times it will need emptying. 

Units with large water tanks are generally more costly than those with smaller ones. The good thing is that they’ll save you the trouble of emptying the tank frequently. 

4. Does it have continuous drain?

Many dehumidifiers accommodate drain hoses as an alternative to manual emptying. With continuous draining, the water collected by the dehumidifier drains out automatically. 

Continuous draining offers the benefit of never having to worry about a full tank. On the other hand, it limits your placement options. 

Some units on our list, such as the Pro Breeze Electric Mini and the Keystone KSTAD30B,   allow both manual emptying and continuous draining. You can therefore move them around easily. 

5. How loud does it get?

Noise is the number one complaint among dehumidifier owners. The only way to assure yourself a quiet unit is to do the research beforehand. 

The noise of a bathroom-friendly dehumidifier comes from its movable parts. Larger units like the  Keystone KSTAD30B, have a compressor, while smaller models like the Honati 2,000ml Home Dehumidifier use much-quieter Peltier technology. 

small dehumidifier for bathroom does not have to be quiet. If your bathroom is close to your bedroom, you might want a unit with minimal noise as possible. 

6. What more does it offer? 

Dehumidifiers, like most home appliances, have advanced exponentially in recent years. Some of the best units around offer more than just moisture control. If your budget is flexible, you can get a safer, more efficient and convenient and quietest dehumidifiers.

Some of the nice-to-have features to consider include:

– Wheels
