Air purifiers are used to clean the indoor air and are available in different forms such as activated carbon, ozone, HEPA and UV whereas humidifiers are used to add moisture to the air and to alleviate winter heating in the homes. Humidifiers come in forms such as impeller, ultrasonic and steam vaporizer.
People most often realize they need a humidifier during the winter, when the air is dry from the cold weather. One of the main benefits of using a humidifier is that it is able to help avoid sickness such as cold, flu, cough, hay fever symptoms, as well as helping to keep the lungs more elastic by providing a healthy balance of moist air. Humidifiers play an important role in keeping a suitable winter living environment by injecting moisture into the air.
An air purifier removes impurities and contaminants from the air we breath. This would include things like dust, pollen, mold spores, allergens, smoke, chemicals, and odors. Air purifiers can be beneficial to anyone who wants to live or work in a healthier environment, and especially to people who suffer from allergies and conditions such as asthma and MCS.

The term VOC stands for volatile organic compound. A VOC is a chemical which easily evaporates into the air at room temperature and is noticeable to us as an odor. Many VOC's are known to be toxic, and we should limit our exposure to them as much as possible. The best defence against VOC's are specialized carbon filters which are available on many of our products.
A HEPA filter is a term which refers to a High Particulate Efficiency Air Filter. HEPA filters must meet strict standards and filter at least 99.97% of all particles larger than 0.3 microns out of the air. HEPA filters are the best defenses against particle pollution and are featured on most of our air purifiers.
A micron is a unit of measurement commonly used to describe the size of airborne particles. One micron is equal to 1/25000 of an inch, and a human hair is typically 50-150 microns. True HEPA filters are 99.97% effective at removing particles larger than 3 microns.
Activated carbon is used in air filters for the absorption of chemicals, gases and odors. It is a form of charcoal which has been processed to open up millions of tiny microscopic pores in order to greatly increase its surface area. When certain chemicals come in contact with the carbons surface a small reaction takes place bonding them together. This causes the chemical to be trapped, or absorbed. This process happens over and over again until all of the carbons surface has been used up. Typically, 1 pound of carbon has a surface area of 125 acres.
