There are some handy indicators for the water level and filter change to make sure you know when to add more water and change the filters.

How to Buy Best Evaporative Humidifier

How to Buy Best Evaporative Humidifier

Photo: Honeywell

1. Coverage Area

Coverage area is one of the most important factors to consider when choosing the best evaporative humidifiers for home use. And here you need something that can provide enough moisture to cover the whole house or room that you want to humidify.

A model that is too large for your space can put in too much moisture, which is also not good while a small one will be practically useless.

The good news is that there are all kinds of evaporative humidifiers out there that are designed to provide different coverage from 100 square feet to over 2,500 square feet. And so you only need to choose what works for your specific space size.

2. Water Tank Capacity

Water tank capacity matters a lot as it will not only determine the amount of moisture the unit can put out but also the frequency of having to refill the tank.

That said, a larger tank is more preferable as it allows the humidifier to add more moisture to your air and ensures you can go longer between refills.

You can get evaporative humidifiers with tanks capacities of between 1 and 5 gallons. But some small models like the Honeywell HEV320B will have a smaller 0.8-gallon tank, which can still be good enough for small rooms.

3. Mist Type

Like other humidifier types, the evaporative ones will produce either a warm or cool mist. Hence, you will also need to decide whether you want a cool or warm mist model.

Warm mist models have the benefit of killing bacteria and other harmful substances in the water as they will boil it first. However, these models will use relatively more energy and can be dangerous to use around kids.

Cool mist humidifiers will not boil the water as they are designed to release as cool mist. This means that, while these machines are safer for use around kids and pets, the mist is full of harmful microbes from the water.

4. Runtime

A long runtime humidifier will allow you to enjoy many hours of uninterrupted use without having to worry about running out of water or having to reset the machine.

The long runtime machines are also more preferable for those that want to use the machine when sleeping or are frequently out of their homes.

Some models like the Aircare EP9 800 will provide an impressive 60 hours runtime, which will allow you to use the machine for several days without refilling. But, for many people, a runtime of just 12 hours is often more than enough.

5. Speed Settings

Speed settings will allow you to customize the machine to suit your preferences or the prevailing climate. Hence, the more the speed settings, the more customizable the machine will be.

While you can get as many as 9-speed settings like what the Aircare EP9 800 provides, sometimes all you need are two settings, which are high and low.

Hence, when it comes to speed settings, it will often be a matter of personal preferences, but you should not settle for something that does not have at least 2 or 3 options.

6. Noise Level

Since these machines will use a fan to circulate the moisture, it will be a far-fetched idea to expect them to be super quiet. The best you can do is to go for something as quiet as possible.

Where you will be using the humidifier matters when considering the noise level. For example, for nursery and bedroom use, you will need the humidifier to be as quiet as possible.

With most of these machines, the noise level will also depend on the speed setting because high-speed settings are louder than lower ones. All in all, to make sure the humidifier is silent enough, you need to make sure that it has a noise rating of under 60 dB at the highest setting.

7. Extra Features

Some features will not be necessary for the evaporative humidifier to function well, but they can make it easier to use and more convenient.

Some of these extra features to look out for include an auto shut-off timer, built-in nightlight, and filter change indicator.

Conclusion 

Keeping the air in your home or room moisturized will be easy with the best evaporative humidifier, and choosing a good model is now a breeze as we provide adequate recommendations.

That said, with up to 2,600 square feet coverage, digital controls, and many other amazing features, the Aircare MA0800 is our best overall model and top recommendation.

But, for users shopping for something more affordable, the Honeywell HEV320B is an unbeatable choice as besides affordability, it is also a highly portable model.
