Call centers dominate the customer service industry worldwide. Companies such as Best Buy and Amazon are all outsourcing telemarketing and customer service functions to consolidate operations, these buildings are typically hundreds of thousands of square feet and have little natural outside air.
New facilities are being construction or converted to house sometimes thousands of employees working 24/7 shifts. The major indoor air quality problem in call centers is the high number of personnel working in a confined area. The majority of indoor air pollutants are invisible to the naked eye and produce no odor. Don’t let cleanliness fool you, an immaculate building can still house deadly pollutants.
Other sources of contaminants in call centers are the people themselves and the computer and copy equipment. Personnel are surrounded by computer equipment, which set up strong electrical fields which transport dust, pollens, gases and other irritants to the personnel bodies and the equipment.
Major complaints in these environments relate to eye and throat irritation, odors in hair and clothing of employees. There is a real concern with the problem of overall human generated contaminants. Body odors, skin flaking, dust, dander, pollen, biological aerosols,, etc., are additional factors causing serious levels of irritation to the occupants, especially the elderly, children and those with pre-existing conditions.
High humidity can support the growth of pathogenic species of fungi and dust mites. This growth is enhanced by the presence of materials with high cellulose, such as fiberboard, dust, lint, skin particles and dander.
Microbial contamination in buildings is often a function of moisture incursion from sources such as stagnant water in HVAC systems and cooling towers. If the relative humidity in occupied spaces, low velocity ducts, and plenums exceeds 70%, fungal contamination (mold spores and mildew) can occur and amplify.
The CosaTron Solution
The solution for this type of pollution is dilution. However the source of that ventilated air is not necessarily outside air. It can be a combination of cleaned recirculated air and outside air. For the purposes of this application, ventilation air is a mixture of recirculated air and/or outside air which has been processed through a combination of filters and CosaTron.
Proper room air change rate in combination with CosaTron and the recommended medium or high efficiency filter, typically solves the problems.
