Fresh Air Concepts' air purifiers are CSA and NRTL/C certified and have been third party real world tested. In addition to several university studies in the United States and Canada.

Mold feed off bacteria in order to grow. Fresh Air Concepts' air purifiers destroy the bacteria, which means mold has no source of food. Without a source of food, mold will quickly be destroyed.

Induct models are designed to run 24 hours a day. That is not to say that they will. The in-duct models have a sensor, which means the unit will only run when the fan is on.

Fresh Air Concepts' air purifiers will destroy biological and chemical contaminants such as bacteria, viruses, mold, mildew, smoke, formaldehyde, cleaning solvents, etc. Click here for a list of contaminants treated by Fresh Air Concepts' air purifiers.

air filter is designed to collect particulate from the air. Air-born living organisms such as bacteria and viruses pass through the filter much like sand would pass through a tennis racket. Some filters such as carbon filters do a good job with odors, but they have to be changed frequently and are very costly. In contrast, Fresh Air Concepts' air purifiers are designed to change the molecular structure of the contaminant through Photo-Oxidation and DNA Sterilization.

Yes, the air purifier kills germs and bacteria and destroys odors; but it does not dispose of the particulate, which is airborne. This requires a quality particulate filter.

Electrical consumption varies by model. The FAC1500X and CMU-16 use approximately 15 watts of electricity and the FAC3500X uses approximately 25 watts of electricity, which is less than the average light bulb.

No, Fresh Air Concepts' air purification systems require limited installation. However, each installation varies depending on the application.

Ozone is simply a naturally occurring form of oxygen in the Earth's stratosphere that shields us from harmful ultraviolet radiation. In the proper concentration, ozone is both safe and extremely effective in killing bacteria, viruses and other harmful airborne microbes. It is also a very efficient at eliminating cigarette smoke and odors. And, while the FDA and OSHA both warn that ozone concentrations higher than 0.

Second Wind Air Purifiers have been tested independently, by universities and privately to prove their effectiveness. They also have various listings:

Air purifiers remove airborne particulate from the air. Air is drawn through the filter and particles are trapped in the filter system. The filtered air is then re-circulated back through your home.

Air purifiers take out a lot of the pollutants from our air which can irritate allergies and asthma. These pollutants include airborne particulate as small as 0.3 microns and includes pollen, dust, pet dander, mold spores and smoke.

The manufacturer's warranty varies from manufacturer to manufacturer. They range from one to ten years. Each manufacturer's warranty is clearly marked on each individual product page.

Microban is used in air purifiers because it is an Antimicrobial agent used to treat an air purifiers HEPA filter. The protection provided by the Microban product prevents development of mold, bacteria or mildew growth on the filters surface which can cause bad odors. The life expectancy of your filter is not affected by the Microban.

Only certain ionizer air purifiers have ionizers built in. Unless the air purifier specifically states that it is has an ionizer it is more likely to use a mechanical filter instead.

Biozone® air purifiers make about the same amount of noise as the average computer fan, much less than a micro-wave or air conditioner, and slightly more than a toaster. Our air purifiers use a very quiet 3 speed fan, similar to a computer fan, this pulls enough air through the air purification chamber at a rate that creates optimum levels of purifying plasma. If sound level is an issue, select a slightly more powerful air purifier and run it at a lower speed.

The inlet grill draws in dirty air. In most HEPA air purifiers, a washable pre-filter traps larger particles. By definition, a HEPA filter removes at least 99.97% of all particles as small as 0.3 microns. HEPA air purifiers were originally developed by the Atomic Energy Commission to capture radioactive dust particles. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter.

Some air purifiers, such as the Blueair units, are extremely quiet, while others can be quite loud when operating at high power. If possible, ask for a demonstration before you buy your air purifier. Also, please see our Air Purifier Noise Graph.

We offer a wide variety of air purifiers designed to treat a number of indoor air quality problems. There are many factors to consider when shopping for an air purifier, but the main factor to consider is the type of pollution which you're trying to eliminate. See our Air Purifier Buying Guide for more information about what you should consider before buying and air purifier, and see our Air Purifier Comparison Chart for an in-depth look at the differences in our air purifiers.
