Personal humidifiers are a perfect solution to keep the humidity level in your home well regulated, helping you to avoid the negative consequences of dry air.

Humidifier Buyer’s Guide

A good humidifier may last you many years. Constant exposure to dry air can be very damaging, so delaying on buying a unit is a bad idea. If you’re ready to take the plunge and looking to filter out the bad and the good in the heavily-saturated market humidifier market, this guide will surely help get you started.

Type of Humidifiers


A vaporizer is a heat-based unit that functions primarily to diffuse oils and liquids into the air. There are some units that combine this function with a general humidifier. In this case, you get a vaporizer humidifier. The benefit of these units is that they are generally filter-less. Cleaning is typically easy, and because they use heat water, there is little concern over germs. There is some danger to these units, particularly if the unit has no automatic shut-off switch. One of these units, left running without water, can become a fire hazard.

Evaporative Humidifiers

Those who remember elementary school science classes will understand how evaporation works. Water is exposed to air and the water evaporates into the air as small water molecules. Evaporative humidifiers work in much this same manner. These units utilize moisturized filters. Air is drawn into the unit, and then forced out. The newly evaporated air is filled with the moisture from the unit, helping to raise the humidity level.

Cool Mist Humidifier

A cool mist humidifier is one of the most cost-effective and easiest to use humidifiers on the market. The humidifier creates a mist from cool water by hurling water at a rotating disc. The water is typically propelled out of the unit with the help of a fan or through simple pressure (the air has to go somewhere, so a small aperture is utilize to force the air to move outward). These units are typically inexpensive, do not use filters, and have very limited features.

Ultrasonic Humidifier

Ultrasonic humidifiers work similar to cool mist humidifiers. However, these devices push the water toward a metal diaphragm that is vibrating at ultrasonic speeds. This creates microscopic water droplets that are then pushed into the air via a tiny fan. While this helps with dispersing the water droplets into the air, raising the humidity much faster than traditional humidifiers, it also results in whatever minerals are in the water at the time to get dispersed onto outside surfaces. Common complaints with these units involve white residue from the minerals in the water building up on surfaces. Some ultrasonic humidifiers compensate for this by using filters.

Why Buy a Humidifier?

It’s easy to miss why buying a humidifier is important. However, dry air can cause many problems. Dry air impacts mucous membranes, drying them out and resulting in cracked skin. Dry air is the leading cause of spontaneous nose bleeds and dry skin. The recommended humidity level for your home is between 40-60% humidity. Below that, and the risks of love humidity develop. Too much humidity, however, can result in the buildup of mold and fungus. Finding a unit that can manage your home’s humidity at just the right levels is extremely beneficial, especially to those with small children and infants.
