What Is A Whole House Humidifier

There are certain health factors that are greatly influenced by not having a dry bedroom or any other room of the house. The next steps of this buying guide should give you a lot more insight on what to look for and what you are getting out of buying the best

How Does a Whole House Humidifier Work?

How Does a Whole House Humidifier Work

An evaporative humidifier, for instance, utilizes an inside fan to maneuver air into the unit and pass it over a water-soaked wick channel to assimilate dampness. After the air has been immersed in dampness, the fan sprays it out into your space so it can circulate. Each different type has its own mechanism and we’re going to talk more when we list those specific types in the following sections. However, the idea behind them all is pretty similar, air is circulated through the device where it gets more humid and then pushed back into the room.

How to Choose the Best Whole House Humidifiers?

There are a couple of aspects that you want to consider when buying the best humidifier for plants, so let’s go through a couple of them:

Coverage Area

The coverage area must be enough to cover your whole home, so make sure you check the specifications when you are on the sales floors. The coverage can start from 2000 square feet and up to 7000 square feet. Of course, you can also have industrial air humidifiers that can handle larger surfaces than that, however, we are focusing on the ones you would get for your home.

Humidification Method

There can be different methods of humidification available today, so to find the best air purifier for smoke we have to choose between the following:

Humidification Method
  • Central systems
  • Evaporators
  • Impeller systems
  • Steam Vaporizers

Mist Type

You can choose from a cool-mist or a warm mist. The cool one is suitable for homes that have children and pets. The warm mist models make almost no noise so they can be a good option as well. Plus, the cool ones can also double as a way to keep the room temperature lower during hot summer days. You need to make sure nobody in your home suffers from respiratory issues because too much humidity combined with the heat can have some negative effects.

Tank Capacity

The tank capacity can differ from model to model, but usually, the tabletop humidifiers come in versions of 1 to 4 gallons. Mostly it’s about the size of the area that you want to cover with a single unit, although it is recommended to spread the size in 2 small areas and get 2 units. This is a case by case scenario that needs to be decided on depending on where you want to use the device. Even though buying several such devices may seem like too big of an expense, the ones that cover the entire home are way more expensive and harder to install.

Customizable Humidity Settings

It is very important to make sure that the model you choose gives you the opportunity to customize the humidity setting and accommodate your friends and family exactly how you like. This is one of the reasons that it is recommended to split the house into 2 areas and don’t go all-in with one single device. Furthermore, there’s no real testing you can do to a humidifier before you install it. That’s why, no matter how many reviews you read or devices you check, make sure to also consider the warranty period since you might need to take the device back if it’s not up to your standards.

Refill Check Filter Indicator

When the digital displays say “CF” that means that you may possibly have to replace its wick filter, CF coming from “Check Filter”. Usually, the message pops up after at least 720 hours of usage. Getting a humidifier with these features will make your life easier as opposed to the devices with just one blinking LED whenever there’s something wrong. A device that tells you exactly what “it needs” is easier to handle and will also deliver more constant results.


The price range goes for little over $100 to models that are more than $600, and that depends, most of the time, on the power of output that the device has and the area coverage that it can guarantee for the end-user. Of course, if you want to add more features to a device, the price can jump all the way to a couple thousand dollars. It’s all a matter of how much you can afford to spend as the positive effects of installing a humidifier in your house are not something that need to be proven anymore.
