Why Humidify?

Your Health. A humidifier will improve your Indoor Air Quality (IAQ), help to relieve dry, itchy skin, allergies and respiratory problems as well as improve hair and complexion. Quite simply, you’ll breathe easier, sleep better and feel healthier. The American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) as well as the American Environmental Protection Agency (EPA) both recommend an indoor humidity setting of between 30-50% for optimum indoor air quality (IAQ) levels.

Your Home. If your home is dry, gaps may appear in your hardwood floors, table-tops may shrink slightly, wooden furniture may crack and pianos can lose pitch as wood adjusts to temperature and humidity changes. A humidifier will reduce the chance of permanently damaging your precious possessions and also reduce the build-up of static electricity.

The Environment.  Our patented Rotary Disc humidifier is designed for both high-performance and high water efficiency. For those who prefer the convenience of disposable evaporative media, our patented Pulse flow-through humidifier saves up to 80% of the water compared to ordinary flow-through humidifiers. In addition to saving water, you’ll save energy (and money) on your heating requirements as humidified air feels warmer to the occupant which allows for a slightly lower temperature setting on your home thermostat while maintaining the desired comfort level.
