About Humidifier Filters

Used for both medical purposes and to make environments more comfortable, humidifiers add moisture to air indoors. This increases the level of humidity, which can help people who suffer from breathing problems like asthma or other upper respiratory issues. Many types of humidifiers include filters that separate toxins from water used to moisturize the air. These include cool mist humidifiers, ultrasonic humidifiers, and evaporative humidifiers (warm mist). Since each type of humidifier can come in small (one-room) sizes or large sizes big enough to humidify an entire building, filters also vary greatly in size, scope, and function. They not only help moisture pass into the air environment, but they also work to trap microorganisms and mineral particles found in water sources that can be harmful if released into the local atmosphere. Cool mist humidifiers employ a fan that forces air through a wet filter, so these filters must be ultra-absorbent and sturdy. Ultrasonic and evaporative humidifiers vibrate water into droplets that then pass through a filter before going into the air. These filters must be more porous than cool mist filters to allow moisture to pass through without being totally absorbed. While filter life has increased with modern advances in technology, it is important to change humidifier filters as frequently as recommended. For small units, this may mean every six to eight weeks. For larger, central units for homes and buildings, this could mean every two to four months. Check with the manufacturer's recommendations for specifics. Typically, if the filter has white dust on it or is brown in color, it is time to change it.
