What To Know Before Buying A Whole-House Humidifier

Consider some essential factors before investing in a humidifier, such as whole-house humidifier costs, type, coverage area, maintenance, and runtime, to ensure you make the right choice.

1. Humidifier Type

Whole-house humidifiers are broadly classified into two types: HVAC-compatible whole-house humidifiers and Console whole-house humidifiers.

HVAC-compatible whole-house humidifiers connect to your central HVAC system and introduce steam to the dry air, elevating its humidity levels. Such types of humidifiers usually have unlimited runtime (limited capacity though) and are best suited for large or multi-story homes.

Console whole-house humidifiers are more suitable for small to midsize homes. They have limited runtime based on their tank capacity and coverage area.

2. Coverage Area

Determine the square footage of your home to choose a humidifier with sufficient coverage for effective humidification without overworking the unit. Remember that the coverage area automatically reduces if the house is not properly sealed. In case of a poorly sealed home, consider getting a more powerful humidifier.

3. Maintenance

Humidifier maintenance is essential to keep your appliance running for years. You must clean a humidifier’s water tank and panel to ensure no bacterial growth. Moreover, learn how to clean its outer body or how to connect it to the drain to prevent mineral buildup.

4. Humidistat

According to the Energy Star market report, “portable humidifiers that do not have a humidistat will run continuously until they run out of water.” excessive humidification can cause mold growth and the development of respiratory diseases. Make sure to choose a humidifier with a built-in humidistat that allows you to set optimum humidity levels (30%-50%) without constant manual adjustments.
