Very large room humidifiers are usually suitable only for homes with large open-concept layouts with good airflow throughout. Another variable to consider when choosing a portable room humidifier is the control feature. Unless you want to monitor the room's moisture level and manually adjust settings to maintain it, these automatic measurement features are handy and worth the extra cost.
Humidifiers with digital electronic controls generally offer more convenience and greater precision than those with mechanical analog controls. How long a humidifier will run between fillings depends on several factors, beginning with the size of the water reservoir. Portable room units are sold in varying sizes of water reservoirs, from one liter to five gallons or larger. A 2-gallon will usually run for 12 or more hours on low, but a 1-liter will require refilling every eight hours or so.
The runtime will decrease substantially if the unit is operated on a high setting or if the air is especially dry. Packaging or product description will usually denote how long the unit will run on a filling. Some water tanks are a little harder to remove and refill, and some lift off easily.
Decide whether the weight of a full tank could be a problem for you. Take time to inspect the unit to see how easy the water tank removes from the base. Also, note if the model will require filter changes. If so, check on the availability of those filters, as well as how easy they are to change.
Consider purchasing a couple of filters along with your new humidifier, as maintenance is crucial to reduce the risk of bacteria and unhealthy air. Evaporative models have wick filters that trap dust and particles. Some units have two-stage filtration, which is important for removing allergens. Mineral deposits in the water form white dust that accumulates on the furniture in the room, but some filters will trap these deposits and reduce the presence of dust in the moisture that is expelled to the room.
Those with hard water may benefit from using distilled water in their humidifiers, reducing the build-up of scale and mineral deposits. All humidifiers require regular cleaning to reduce bacterial growth. Check the product information as some models have dishwasher-safe water reservoirs, which makes cleaning easier. The base of the unit also requires manual cleaning regularly. Hot water might also cause burns in the event of a spill. Humidifiers add moisture to the air.
Cool-mist humidifiers may help ease coughing and congestion due to a cold. But more research is needed. Some research has found that heated humidifiers don't help cold symptoms.
Warm-mist and cool-mist humidifiers are equally effective in humidifying the air. By the time the water vapor reaches your child's lower airways, it's the same temperature regardless of whether it started out warm or cool.
If you use a humidifier, be sure to keep it clean to prevent mineral buildup and the growth of bacteria and molds. Humidifiers that hold standing water, particularly cool-mist humidifiers, can disperse these materials into the air. Warm-mist humidifiers generally disperse less, if any, of these materials into the air. Emptying the tank and drying all surfaces of the humidifier daily is one way to safely keep it clean.
Also, consider refilling the tank with bottled water labeled "distilled" or "purified," which has a lower mineral content than most tap water.
