What You Should Pay Attention To When Buying whole house humidifier


Type of Humidifier – Cool vs Warm Mist

At first, select the type of whole house humidifier you are searching for – cool or warm mist, or maybe a dual unit would better suit you. If you have any hesitations, you’d better discover the differences between a cool and warm mist humidifier to select the best for your needs.

Know more about why some prefer a cool mist when young children are present and why it’s considered safer.

Also there are models that can both, humidify and purify the air – they always cost more money, however, they might be worth taking into account. Read more sources to know why too low or high humidity is usually problematic.

Type of Humidification Processes

There are two common types of processes that are used in humidifier to produce moisture, or steam – an evaporation process which is in general the cheapest, and ultrasonic which produces a better water mist.

Each type can be used in cool or warm mist models, but ultrasonic appears to be safer because it does not generate a mist by boiling water.

Thus the humidifier does not contain hot water and won’t create any danger in case the device is knocked over.

Humidifier Styles: Personal, Portable, Console or Flow-Through Bypass

A personal humidifier is compact (to 1 liter), so you are able to take it on trips to provide moisture wherever you need though, the coverage area isn’t wide enough.

Portable room humidifiers are mostly used in bedrooms and living areas and can have a varying capacity from compact to a large room size.

Console style humidifiers are bulky, free-standing devices on wheels. Console models are considered whole house humidifiers due to their larger capacity and effectiveness.

Flow-through bypass units are another type of whole house humidifier and designed to be installed on the home’s duct system.

Determine Capacity

To choose the most suitable model for your needs you should consider a coverage area in square footage which the humidifier can cover.

You may need to take measurements to determine the room size you are looking for. For a small apartment a model for 700 square feet will be okay.

There is a high probability that using too large a humidifier for your room, some amount of condensation will appear that will cause bacteria and mildew.

Capacity is usually marked on the packaging. Do not confuse capacity with moisture output, which will be higher.

Controlling Moisture Output

Some humidifiers have two or three built-in variable fan speeds, and others may be equipped with a hygrometer for indicating the humidity level in the room and also a humidistat which can be set to cycle on/off and maintain the level needed.

These extra features cost extra, but they are handy to monitor the moisture level and adjust settings.

Refilling Convenience

Water reservoirs in humidifiers can vary from 1 liter to 5 gallons or larger. It’s up to you to decide how often you want to refill it.

A 1-gallon tank will require refilling after 8 hours of use, while 2-liters will work for 12 hours or so.

The durability depends on the speed mode (low or high) and the amount of dry air for faster moisture generation in the room. The product description will usually mark such features.

Ease of Handling & Maintenance

Some water tanks are lightweight, so you can lift and refill them easily, others can be harder to refill. If the weight of a full tank is a problem for you, try to discover the process of removing the tank from the base.

Also pay attention to the requirements for changing filters in each model. Some humidifiers are filter-free, so there is no problem.

In case there are filters, don’t forget to buy a couple of filters along with your new humidifier because it’s critical to decrease the risk of bacteria and unhealthy air.

Operation Noise Level & Settings

If you are looking for a humidifier for the bedroom or a children’s room, you must consider its noise level. You should choose one with a low, night, or silent setting.

Your humidifier should have at least two settings, high and low. The quietest ones in operation are ultrasonic humidifiers due to the lack of boiling water (hissing) and moisture is spread in a very fine mist.

Benefits of Changing Humidifier Filters

Almost all house humidifiers have filters. Evaporative models are known to have wick filters that absorb particles and dust.

Some models, made for removing allergens, have two-stage filtration. Mineral deposits in the water forms white dust that accumulates on the furniture in the house, some good filters can trap these deposits and diminish the presence of dust in the moisture that distributed through the room.

Using distilled water in a humidifier can be beneficial for those who have hard water, thus, reducing the build-up of mineral deposits and scum.

Safety Shut Off & Other Features

More convenience is provided by automatic digital humidifier controls. Nowadays almost all models have safety features such as an automatic shut off in case the water reservoir is empty.

If there is no information mentioned on the packaging, ask the retailer. Otherwise, you will have to control the humidifier when it runs dry.

Another useful feature is a built-in humidistat which will regulate the humidity level in your room.

Regular Maintenance & Warranty

For bacteria growth, all humidifiers require regular cleaning. For simplicity, some models have dishwasher-safe water reservoirs, so look up the product description.

The base of the humidifier requires a regular manual cleaning as well. The retailer provide warranties which are generally 1 year, but some models go for longer periods.

Select the model you can clean solely as it is more economical than needing service after the warranty’s expiration.

More About Buying Air Quality Appliances

It’s important to acquire a separate hygrometer in addition to the built-in humidifier hygrometer, to monitor your home’s moisture level all year.

It’s not unusual to use a humidifier at home to add moisture during winter season, when the heating system is operated, however in the spring and fall, an additional hygrometer will help indicate if there are certain areas of the house where excess moisture needs to be removed.
