Choosing the best humidifier can be time consuming but don’t worry we have reviewed the top 6 best whole house humidifiers. We recommend, the Honeywell HCM350B, it runs quietly and can humidify your room quickly. 

A humidifier is good for nose, throat, and lips and can relieve dry skin and sinuses, but running a whole-house humidifier for months can involve more maintenance than most people think. A good whole-house humidifier should be easy to clean with minimal maintenance and should have a good coverage area.

It’s an ideal whole-house humidifier if you want something that works straight out of the box. This model has a UV light system that destroys your water germs before releasing any mist and also has a wicking filter which helps to capture mineral deposits from hard water.

The humidifier has three-speed options, low, medium, and high. It self regulates the humidity level because it’s an evaporative humidifier so it cannot over humidify the air as other ultrasonic humidifiers do.

Its water tank is easy to fill and is also dishwasher safe, so cleaning the tank is as easy as cleaning your kitchen utensils.

Can Humidify Multiple Rooms

This model can humidify multiple rooms at the same time. You can leave it out in the spare room, so its noise doesn’t disturb you while you’re sleeping. 

Flaws but not dealbreakers

It is quite noisy. At low speed, it makes an electrical humming like noise which is due to the design of housing, at medium speed the noise increases quite a bit which is tolerable. But it’s at high speed when the noise gets really loud.

Some people think it’s a big issue, but the high-speed mode is like a turbo option to humidify your room quickly and then switch to low or medium speed. It’s not meant to run on high speed after the initial hour or two of operation.

The final thing we would like to draw your attention to is its area coverage of up to 2,400 square feet. If you have a large place, then it still can do its job. Some people think 2,400 square feet is not enough, but we think it is enough for most people.

Installation and Maintenance

This humidifier runs quietly and only requires minimal maintenance. You will not have to do anything more than once a year, other than programming it. The installation can be a little complicated if you have no experience. The manufacturer recommends installation on the return air duct by a licensed HVAC professional.

Flaws but not dealbreakers

The unit lacks a non-volatile memory; it means it will lose its programming settings if the power is lost though reprogramming is easy and does not take much time. We think this is not a big issue, and it should not be a significant factor in your purchasing decision.
