When you are thinking about using an ionic air purifier in your home, your office, or your car, you should be aware of the different types and the pros and cons of each. Then you should check other factors such as initial price and the costs of operation and maintenance before making a choice.

It is important not to confuse ionic air purifiers, which emit a small amount of ozone gas as a by product, with ozone generators. Ozone is a colorless and almost odorless gas which can clean air of organic particles, such as bacteria, viruses, and odors, but in high concentrations is harmful to breathe. These machines are useful tools for professionals but are not suitable for use in occupied spaces.

Ions, electrically charged atoms or molecules, are produced with a negative charge by ionic purifiers. The ions bond to air-borne contaminants, whether allergens such as molds or pollens, or bacteria. The toxins are then collected by plates that have positive electrical charges, and they are thus removed from the air. Government bureaus and scientists are debating about the effectiveness of this air quality technology; many purifiers made by national companies claim to have clinical trials that prove their products to be safe and beneficial.

More than one purification process may be employed on an ionic purifier. HEPA filters are effective in removing particles from air, UV light can kill organisms that cause disease and allergies, activated charcoal absorbs chemical gases, and sanitizers help reduce or eliminate odors. Pre-filters may get large particles out and help the inner filters work better and last longer.

Ions move on their own, so many models do not have fans. Fans move the ions faster in the air, but may cause the unit to make more noise. The specifications of circulation and decibel levels of operating noise should be easy to find in the product description of reputable manufacturers. The level of ozone produced is important as well; less than three parts per million is a safe level and many ionizers will produce far less. Too much ozone in the air is a health hazard.

Many who suffer from allergies want a safe way to get pure air to breathe, free of pollen, smoke and cooking odors, pet hair and dander, mold, and dust mites. There are clinical studies, government reports, guarantees, and testimonials that help to guide those looking for a safe and effective way to get clean air.

An ionic air purifier to make living healthier and more comfortable is the goal, and careful research online can provide much information on this subject.
