Pros And Cons
How To Pick The Best Whole House Humidifier in 2021?
Once you get aware of the factors to consider, you can easily pick the most suitable whole house humidifier. Let’s get into more details on how to pick it.
1. Types of Whole House Humidifier
There are 3 major types of these appliances, they are evaporative, steam, and self-contained.
i. Evaporative humidifiers
An evaporative humidifier adds enough moisture to the dry, warm air blowing out of a furnace. For constant water supply to a humidifier pad, it uses a direct water line. Whenever the warm furnace air passes through the wet pad, it evaporates the water and soaks it up. Evaporative humidifiers are further classified into the following types.
Bypass humidifiers: They redirect furnace air via a bypass duct. The circumvented air passes through the humidifier pad to collect moisture before it gets dispersed in the entire home.
Powered humidifiers: They contain a fan that pulls water over the humidifier pad. The same facilitates the efficient distribution of moisture within the air compared to a bypass type.
ii. Steam humidifiers
These types of humidifiers store water within a canister. Whenever low humidity is detected, the steam humidifier boils the collected water into steam through electricity. The steam is then dispersed in a furnace duct system.
iii. Self-contained humidifiers
If you don’t possess ductwork, these types of humidifiers can precisely moisturize your home. Their operation is not dependent on any furnace system. The contained fan circulates humidified air.
2. Size of Whole House Humidifier
When choosing the best whole house humidifier based on size, you need to consider two key factors. They are available space in the home and the building envelope. Make sure to first assess the area of the space where you want to set up a whole house humidifier. Certain whole house humidifiers are designed to humidify a space with an area of 6,000 sq. ft. or even more. Hence, for a spacious home, make sure to buy a whole house humidifier with large coverage.
Another key factor is the building envelope. Analyze how drafty your home is. Typically, older houses were constructed less efficiently and they lost air more quickly than modern houses. If your house is older then buy a whole house humidifier that offers efficient airflow.
3. Ease of Use
Certain whole house humidifiers are more difficult to set up than others. You may come across some humidifiers that just need plugging in to the wall whereas others need professional installation. Also, you need to consider the size of the water tank of the humidifier and how frequently it needs refilling.
4. Additional Features
Considering some additional features let you operate the humidifier quite conveniently. One of the additional features you can consider is the programming feature on the easy-to-read display. Another additional feature is the inclusion of permanent memory. It makes sure the setting you programmed gets saved and can be accessed even if there is a power failure in the home.
Every whole house humidifier requires periodic maintenance to let it continue working efficiently without compromising on durability. Before buying a whole house humidifier, check whether it would need the replacement of any accessories during the maintenance or after a specific period. Also, note the level of difficulty of the periodic maintenance.
