In-Duct Air Purifiers utilize the fan or air exchange unit in your existing HVAC system. This reduces operating cost since it doesn't contain a fan. When contaminants enter your HVAC system and pass over the In-Duct Air Purifier's UV lamp, they are destroyed. Air coming from your HVAC system will have low levels of negative ions and ozone. These will oxidize airborne particulates, eliminate odors, and break down other unhealthy fumes and organic contaminants. See similar questions...

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. See similar questions...

In-Duct Air Purifiers are OK for use with virtually all filters you might have on your ventilating system. The performance of an in-duct air purification system will not be affected by an electrostatic air filter. Approximately 15 months of continuous use or 9,000 hours is the typical bulb life. Today cost less than$36 for most In-Duct Air Purifiers units. Yes you can do the replacement process yourself. See similar questions...

In-Duct Air Purifiers compare in size to a portable phone. The bulb's size ranges from 6-12 inches. The Biozone In-Duct Air Purifier A1500 is compatible with the smallest ductwork. See similar questions...

Oreck Air Purifiers use a five-stage purification process to clean the air. The diagram below illustrates the various purification stages. The five-stage purification process which Oreck uses effectively filters 95% of particles as minute as 0.1 microns. First, a pre-filter captures large particles such as hair, lint etc. Electricity is used to positively charge smaller particles, which are then locked in by the alternately charged plates of the collector cell.

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. See similar questions...

These machines release negatively charged ions into the air, which are attracted to positively charged allergens and pollutants. These neutral particles then fall harmlessly to the ground where they can be vacuumed or dusted from furniture. See similar questions...

Many air purifiers now include a UV stage whereby the air and its contaminants are exposed to ultraviolet light after the HEPA and Carbon filtration process. UV light in the range of 185 nm to 265 nm is extremely effective in killing microorganisms such as bacteria and viruses by disturbing the DNA of the organism at the molecular level. The at-risk elderly and very young are typically the population for which UV air purifiers are purchased. See similar questions...

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. See similar questions...

The In-Duct Air Purifier employs the same exceptional air purifier technology as other air purifiers in the Biozone Scientific line. For example, a patented, high-purity UV lamp produces low-level photolic ozone, negative ions, and purifying hydroxyls. Germs, viruses, bacteria, and molds and mildews that may be found in the ductwork are killed by the UV light. See similar questions...

When you schedule your service, you will pick a date that works best for you.

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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. See similar questions...

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.
