There are three easy steps to determine which Biozone® Air Purification model is right for your residence or business:

1. Determine the square footage of the space or environment to be purified.
2. Determine the contamination level of that space.
3. Multiply the square footage of the space by the contaminate factor to arrive at an estimate of the size of unit required.

Determine the Square Footage

The coverage area of a Biozone® Air Purifier is based on the square footage of the area measured in square feet, although the actual measurement is cubic feet -- we assume an average 8' ceiling height.

Because Biozone® Air Purifier do not purify through walls (no air purifiers can do that; the FTC has disallowed such claims), and work best in a single room or open area, the layout of your home or office area is important in selecting a unit or units. Ideally, install an in-duct system if you have central heat and/or air conditioning because these units purify the entire home very evenly, purifying the air everywhere that is served by your ductwork. See the in-duct models for details on selecting a duct-installed unit.

If you don't have existing ductwork or if you don't want to install a whole-home unit (i.e., if you only want a unit for one or two rooms, you rent, live in an apartment building or want a unit for your office), it's easy to select a room unit that will be very effective. Simply keep in mind the largest open area of your indoor space and match the unit model number to that square footage. For instance, if you have an open downstairs of approximately 1000 square feet with light odor and contamination, you would select a Biozone 1000. Small units (Biozone 100, 102 or 500) are recommended for bedrooms or small office rooms or cubicles.

Square Footage of Your Space: ______________

Determine the Contamination Level

Choose the Contaminate Factor that best describes your air quality.

Contaminate Factor	Description of Contaminate
1	Light odors. No pets. No smokers.
2	Light odors. 1 pet or 1 light smoker.
3	Moderate odors. Multiple pets or mild smoking in house or business.
4	Moderate odors. Multiple pets and smoking in house or business.
5	Strong odors. Multiple smokers and/or ongoing contamination problems. Restaurants, hair salons, pet stores, veterinarian offices.
6 - 10	Extreme odors. Sports bars with heavy smoke, nail salons, commercial chemical or animal areas.

Perform Calculation

  _________  Square Footage of Space to Purify

X _________ Contamination Factor

= _________ Total Square Footage

Example 1:

1500-2000 square foot house with 1 smoker: Multiply 1500-2000 by a Contaminate Factor of 2 to get 3000-4000. Depending on the layout of the house, either two Biozone 2000 units placed separately or one Biozone 4000 should cover the area effectively.

Example 2:

450 square foot nail salon: 450 X 8 = 4000. A Biozone 4000 would be the minimum unit necessary in this environment. Depending on the numbers of nails being done, a Biozone 5000 or ATC I (used for higher contamination levels) could be required.

Maximizing Performance

Using a purifier in a room that is larger than recommended or in a small area with poor circulation will not produce optimum results. That's also true for a room with a ceiling higher than 8 feet. For peak performance in a high-ceiling room, therefore, a purifier with a larger capacity than recommended for the room's area should be used. In very large rooms, two small purifiers work better than a large one because the purifying agents produced by the units have less distance to travel.

If there is more than one cigarette smoker, it's best to move up two models. For example, if the downstairs is 1000 square feet and two smokers live there, a 3000 model might be in order here. Or, depending on the layout, a 2000 and a 1000 or even three 1000s. If you have good air circulation from room to room, and possibly even ceiling fans that you run regularly, a larger single unit will do a fairly good job of doing a large area. A space that is compartmentalized, i.e., lots of small rooms, narrow hallways and poor air circulation, would be better suited to multiple smaller units.

It's usually better to get a unit that is a little "too big" rather than one that is too small. All units feature 3 or 4 position fan switches to allow you to control output if desired. This means that while a 2000 unit is designed for a 2000 square feet space with normal contaminant levels, it can be "turned down" for smaller areas or times when pollutant levels are low (dogs are outside and no one is smoking).
