Indoor air quality has a significant impact on your health and comfort. With the various air quality products on the market, such as humidifiers, vaporizers and air purifiers, it’s important to understand the functions and benefits of each type of air system in order to make the right decision about which to include in your home HVAC system.
A humidifier is a device included in your HVAC system or as a stand-alone unit that releases a cool mist into the air. Humidifiers increase the overall relative humidity indoors, and such devices help maintain optimum humidity levels in your home. Generally, humidity levels of 40 to 50 percent are ideal in the warm months, and between 30 to 50 percent work well during the cool months.
When humidity levels are too low, various health problems result, such as dry sinuses, bloody noses and cracked, chapped lips. Humidifiers relieve such problems, as they release soothing moisture into the air. The use of humidifiers can also help symptoms caused by respiratory illnesses.
According to the Environmental Protection Agency (EPA), mold growth is most likely when the humidity levels go above 45 percent. The mold growth can be avoided by properly maintaining and cleaning humidifier systems, as unclean humidifier filters can breed harmful organisms such as mold and bacteria.
A vaporizer is a machine that releases a warm mist into the air, increasing humidity and making breathing easier. Vaporizers work by boiling water and releasing the hot steam. According to the National Institutes of Health, vaporizers can help relieve symptoms of sinusitis. A benefit of vaporizers is that the steam is heated to such high temperatures that it tends to be germ-free.
Keep stand-alone and central humidifiers and vaporizers clean by following manufacturer directions for cleaning the system. If you are unsure about how to clean your central humidifier or vaporizer, consult a professional heating and cooling specialist for assistance.
Air purifiers are your best line of defense against indoor air pollution. According to the U.S. Environmental Protection Agency, air purifiers remove indoor pollutants from the air, which is good for individuals with asthma and allergies.
Electronic air filters are generally attached to heating and air conditioning units. They use a process known as electrostatic attraction to trap pollutant particles in indoor air. HEPA filters may also be a part of an HVAC system and are included in stand-alone air purifiers. Such systems capture and filter out pollutants. Gas-phase filters are another type of filter that removes gaseous pollutants from the indoor air.
In order to experience efficient air-conditioning and heating and proper air filtration, all purifier filters must be changed or cleaned on a regular basis.
