How is this Purifier different from a HEPA Air Filter?

UV air purifiers, like the Biozone, are unlike HEPA Air Filters in that they do not require loud fans to filter out the air. Biozone will silently clean the air and surface of unwanted contaminants all from one central location in your home, office or apartment by creating a "blanket" of cleaning agents that search out pollutants in all four corners of a room.

With no filters to replace, these air purifiers are virtually maintenance-free and rid the air of biological contaminants like bacteria, viruses, mold and hazardous fumes. Even more effective than HEPA filters, Biozone also neutralize all odors from cooking, smoke or smelly laundry using UV Light Technology. Click here to learn more about UV Light Technology.

What Maintenance is Required?

Virtually None!

The only thing you have to do is replace the UV Germicidal Light Bulb once a year; it's just that easy!

It is important to replace the bulb every year to ensure that the unit is working at peak performance and to prevent the bulb from burning out. If this occurs, you will need to replace the fuse as well as the bulb.

As a courtesy, our highly attentive staff will remind you, via email, every year that it's time to replace your lamp. So sit back, relax, and enjoy the benefits of maintenance free air purification.


How to Select the Right Size Biozone Air Purifier

Consider 2 factors:

  1. What is the Square Footage of your space?
  2. How many contaminants are Present in your space?

When your space in bombarded with pollutants, you need a larger sized model to handle the same square footage. Example, your home is 1200 square feet and you have high humidity (mold growth), you need the Biozone PR20 which covers 2000 square feet to effectively clean your space.

  • the list is unimaginable


Who Should Not Use the Biozone Air Purifier?

Asthma Sufferers.

In very rare cases, ozone has been known to trigger asthma symptoms in ultra-sensitive individuals. To prevent the possibility of this occurrence, we strongly recommend choosing another, ozone-free air purifier like the Airfree.


Purify Your Air AND Surface!

Biozone is one of the best at eliminating the following from the air, hard surfaces, carpets, draperies, furniture and clothing:

  • Odors such as smoke (from fires, cigarettes, cigars) pets, gym clothes, kitchens, bathrooms, mold, and musty basements, etc.
  • All Viruses and Bacteria.
  • VOC’s (Volatile Organic Compounds) released from new paint, carpet, wood, building materials, furniture, cleaning chemical, etc.
  • Mold and Mildew


Biozone Uses Nature's #1 Source of Cleaning Power: Negative Ions

Ions are natural particles in the air that have either a positive or negative charge and are found naturally in the air. Negative ions attach themselves to airborne particles such as dust, pollen, smoke and dander and drop them from the air. Negative ions can be actively produced by high voltage electricity run through metal which is how the Biozone effectively creates ions to clean the air.


Biozone's Advanced UV Purification Process

For All You Science Buffs

Biozone Air Purifiers dramatically improve indoor air quality, ensuring that the air people breathe is fresh and safe. Through an advanced UV purification method, these products effectively neutralize unpleasant odors and kill unhealthy contaminants. The key to the purification process lies in the proprietary, dual-purpose UV lamps, specially designed for Biozone. This dual purpose consists of purification by direct UV light exposure and by a “search and destroy” approach to decontamination and sanitation.

Ultra violet light is used to neutralize odors and volatile organic compounds, while killing germs, bacteria, molds and dust mites. Biozone takes advantage of the high frequency, high energy and germicidal characteristics of the UVC light spectrum to accomplish this. This UV process is somewhat analogous to the process of creating steam out of water. The ambient air and moisture that is naturally occurring around us becomes energized as it is exposed to the high intensity UV light, equivalent to exposing water to a heat source.

This high energy state allows the O2 (Oxygen) and the H2O (water vapor / moisture) to collide and temporarily combine or break into various molecular forms such as O, OH, O3, H2O2, in addition to the always present O2 and H2O. These new and temporary molecules are effective oxidants and cleaning agents, helping decontaminate the air and surfaces.

These cleaning agents are released into the air to “search and destroy” pollutants. Over time, the energy level of these molecules diminishes and the ambient air and humidity returns to normal levels, equivalent to the process of condensation of steam into water.

O3 (ozone) is a bi-product of this process. Fortunately, it is neither the main output nor the only output. Biozone make a deliberate effort to manage the amount of O3 generated, through the use of custom-designed, dual-purpose UV lamps, therefore blocking part of the UVC spectrum that contributes to a higher production of O3.

Concerning bacteria, mold, viruses, dust mites and other microscopic organisms, they are known to be affected by a specific range of the UVC spectrum near the 253.7nm UVC wavelength, better known as UVG. When these microorganisms are “directly exposed” to the UVG light, their DNA is altered to the point of self-destruction.

While, the UVC high frequency light cannot penetrate the human skin enough to cause any considerable damage, it could cause minor eye irritations or burns after prolonged exposure. Therefore, we strongly discourage direct visual exposure, especially during installation or lamp replacement. Please read the product manual for specific instructions.

    Biozone PR20 air purifier

    Posted by Frank Gazda on 17th Dec 2020

    This purifier is great, I have had the older one for about 15 years, and it died. Bought one first of the year 2020, was using it and let my granddaughter use it for a month, so I bought another one. They are great, nice go come into the house and it smells fresh and clean. It is a little prices, but it does the work that biozone clams.

    Posted by Victor Coffey on 27th Nov 2020

    We have owned a Biozone for years and gave it to our daughter to try. Within 2 weeks we missed it and bought a pr20 (for our office. Covid) and a pr10 for our home. We love them. Thanks.

    Love These Biozone Units

    Posted by Audrey on 4th Apr 2017

    After much research and many mistake purchases of lesser units, Biozone 2000 (PR20) is my first choice for an air filter/ cleaner for my home-office. I have one on each floor running full time and love them.

    Still awesome!

    Posted by Byron H. on 11th Dec 2013

    Had an older Biozone 1000 and ordered a new lamp and fuse. Couldn't resist ordering the PR20 at the same time. It's still awesome, how something so small and maintenance-free can work so well. My asthma hates it; I love it. Thanks for such a great product. I want one for my car.

    Hands-Off Biozone Air Purifier

    Posted by Unknown on 4th Mar 2013

    Sometimes having an air purifier is a lot of work, what with the filters and the energy use and all the maintenance, but this Biozone air purifier doesn't really have those problems. Despite the fact that you never really have to clean the thing, the Biozone air purifier can clean up to 2000 square feet of dirty, dirty air. Even the smoke smell that routinely drifts around the house because of certain people whose names I won't mention here is eliminated by these Biozone air purifiers.

    Keeps away filthy bacteria and germs in our barber shop

    Posted by Donta fromChitown on 14th Apr 2012

    Anyone not in the trade of cutting hair may be surprised at how some people maintain there hair. I was appalled the first time I saw someone with a head full of nasty..let's just call it. I've had to wear gloves at time cutting people's hair for fear of catching something from them. I talked to a salon down the street and asked if they had anything to counter what at times creeps through that door of ours and they told me about the biozone purifier. We bought it and just knowing it is killing all the junk coming through our door is great but it also improved the smell of the shop. Now, I recommend it to all my clients.

    cook fish with no odors

    Posted by Chris Wood, 2006 on 4th Apr 2012

    I have to tell you how nice it is to cook fish and not have our place smell like it for days. When my husband brought the air purifier home I couldn't imagine it could get rid of fish odors, but it sure does. We now have fish much more often than we used to because there just is no odor anymore. The machine also keeps our condo (which is in an older building) smelling fresh and clean all the time. Your air purifier really works well.
