Good For Business!

High performance Electronic Air Cleaners like the C90A provide a healthier environment for customers and employees by removing both harmful and irritating particulates from the air. Clean, fresh-smelling air can greatly enhance the customer experience, contribute to a sense of "wellness" and create a more pleasant overall experience.

As staying healthy becomes more a part of people's daily lives, it becomes more important for businesses to provide them with the environment they seek. Using an electronic air cleaner like the Friedrich C-90A in your store, restaurant, nightclub, gym, waiting room, hospital or hotel will help you meet your customers' needs.

An added bonus is that employees with allergies or particulate sensitivity will find it more pleasant to be at work, and will not have to suffer through a workday stuffed up and miserable. Happier, healthier employees can do a better job of serving your all-important customers.

How often should I replace the carbon filter in my air cleaner?

The activated carbon filter must be replaced when it is no longer effective in eliminating odors. The life of the carbon filter will depend on the concentration of odors and fumes in the air passing through the air purifier. Under normal operating conditions, the carbon filter should last from three to six months. NOTE: the carbon filter must be in place for the air cleaner to operate.

How quiet is the purifier?

The unit has three fan speeds. Below is a chart that shows decibel (dBA) readings taken three feet away from some common household sounds.

Does the air cleaner produce any ozone?

As with any electric appliance, the Friedrich Electronic Air cleaner does produce small amounts of ozone. During a 24 hour test conducted by Underwriters Laboratories (UL), the highest level measured was .033 parts per million (PPM). By comparison, the maximum allowable indoor concentration recommended by the FDA (Food and Drug Administration), ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) and UL is .050 PPM. Under normal conditions, ozone is very reactive to most surfaces and will convert rapidly to oxygen.

How large an area will the unit handle?

The purifier will effectively clean the air in an area up to 480 square feet.

Will the C90A discolor walls, drapes or furniture?

No, unlike some ionizing filtration systems (negative ion generators) which discharge elements back into the air, the C-90A is an electrostatic precipitator which traps all particles on collector plates within the unit.

How much electricity does the C90A require?

The filter only uses about as much electricity as a household light bulb, as little as 40 watts on the low fan setting.

How do I clean my unit?

To clean the electronic cell and maintain optimal performance, lift it out and submerge it in a bathtub or other suitable container with mild detergent, or simply put it in your automatic dishwasher.

Why is my Air Cleaner making a popping sound?

During initial use, “snapping” sounds may be heard. This is normal, and the unit may continue to make these noises during the first few days of operation. After this initial start-up period, only an occasional “snap” will be heard, indicating the unit is cleaning your air. Note: As the air cleaner’s electronic cell becomes dirty, it will “snap” more frequently. When this occurs, you should wash the cell.

The new and improved Friedrich C-90B unit is now available. This unit is virtually identical to the C-90A but increases the range and clean air delivery rates of the older unit.
