There is no doubt that a humidifier is one of the best ways to control the level of humidity in your home. But, what you might not know is that a model with a humidistat will do an even better job.

With the best humidifier with humidistats, you will have more control over the humidity level in your home and get a quieter humidifier as these types will often not rely on fans.

Also, humidifiers with humidistats are more cost-effective as they eliminate the need for buying a separate hygrometer.

In this guide, we look at some top-rated humidifiers with humidistats and also provide a buying guide to help make it easy to pick one.

What To Check Before Buying Humidifier with Humidistat?

How to Buy the Best Humidifiers with Humidistat

1. Power of Humidifier with Humidistat

Any humidifier you choose whether it has a humidistat or not needs to be powerful enough to ensure efficient and effective operation. Hence, power is always one of the first things that you will need to consider.

Here the more powerful the humidifier the better it will be for you. But given that the powerful models tend to be expensive, you should consider your needs and try to match them to the model you choose as sometimes you will not need a very powerful model.

Something with a power rating of 120V/60Hz, 30W like the TaoTronics TT-AH001 should be powerful enough for most homes and users. And this is because it strikes a good balance between price and power.

2. Coverage Area

The coverage area also matters a lot as you will want a unit that can humidify the specific room or space that you have otherwise you will have to buy several units.

Most humidifiers with humidistats will cover anywhere from 100 to over 5,000 square feet, and so there is something for almost any room size out there.

That said, sticking with something with wide coverage like the Aircare MA1201, which covers up to 3,600 square feet is always a good idea as it will be ideal for both small and large rooms.

3. Tank Capacity

A good humidifier should have a large tank to ensure longer intervals between refills. Also, with a large tank, the unit will add enough moisture to your air before it runs out of water.

Models with larger tanks tend to be pricier, but the convenience of not having to refill them often makes them worth the extra bucks.

Most of these machines will have anywhere from 1 to 5-gallon tanks, and so it will be up to you to choose the most appropriate one for you.

4. Fan Speeds

The level of humidity you need to add to your air will depend on the season. In winter and summer, the air in your home tends to dry out, and so you need to add more humidity. But, in other seasons, you will only need to add a little moisture just to make things cozier.

With this in mind, the best humidifier with humidistat for you is one that will allow you to choose from different fan speeds. For example, the Aircare EP9 800 has 9-speed options, which makes it possible to select your preferred performance level more precisely.

5. Runtime

Runtime is the amount of time that the humidifier can run continuously without having to refill. What makes it important is that you will not always be around to refill the unit. Also, you need the humidifier to continue running even when sleeping.

A good model should provide at least a 12-hour run time as it will ensure you will not have to wake up in the middle of the night to refill it.

However, something with an even longer run time than this, like the 70-hour runtime Air Innovations MH-505-BLUE will be even more convenient as you can go several days between refills.

6. Ease of Use

While the humidifiers with humidistat might not be the most complicated appliance, the ease of use still varies between different models.

One of the key determinants of the ease of use for the model you buy will be is the controls. That said, a model that will include some simple and clearly-labeled controls will give you the easiest time.

A humidifier with a digital display will also be more preferable as you can easily monitor the humidification level.

7. Noise Level

Because you will in many instances leave the humidifier running when you go to sleep, it is important to make sure that what you buy is not very noisy.

To determine whether the model you buy will be silent enough or not, you need to check the noise level. Something with a noise rating under 60 dBA is often good enough.

Hence the 38 dBA rated TaoTronics TT-AH001 will provide a quiet enough operation for use even in the bedroom.

8. Maintenance

Maintenance is an important part of owning a humidifier, and so as you choose one, you need to make sure it will make the maintenance more effortless for you.

For a humidifier to be easy to maintain, it should be easy to take apart and assemble. Also, something that will come with detailed and easy to follow directions will be the easiest to maintain.
