Fwd: RE: [Small College EHS] Air Purifier Advice Needed
Bob A. Jackson
In some respect these unit air purifiers are treating the problem after it’s created. Best to control mold before it’s a generated.
However, my experience has been that unit air cleaners are popular with building occupants in terms of indoor air quality. It may be more psychological than real.
Apparently this unit uses an UV light source coupled with a titanium dioxide catalyst. There is also an optional ozone generator. I haven’t run across this in the past, but there is literature supporting the effectiveness of this combination (UV and TiO2) as a biocide. So I am guessing this could work.

I do not know about the IT 1500 but we do know that the key to mold prevention is moisture control. There is a wealth of great information on the subject coming to you from the group already. The EPA website also has many useful recommendations for the prevention of mold in schools that we currently use at our College because we have many spaces below ground level:
http://www.epa.gov/mold/mold_remediation.html
Mold Prevention Tips
- Fix leaky plumbing and leaks in the building envelope as soon as possible.
- Watch for condensation and wet spots. Fix source(s) of moisture problem(s) as soon as possible.
- Prevent moisture due to condensation by increasing surface temperature or reducing the moisture level in air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid).
- Keep heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly, and unobstructed.
- Vent moisture-generating appliances, such as dryers, to the outside where possible.
- Maintain low indoor humidity, below 60% relative humidity (RH), ideally 30-50%, if possible.
- Perform regular building/HVAC inspections and maintenance as scheduled.
- Clean and dry wet or damp spots within 48 hours.
- Don't let foundations stay wet. Provide drainage and slope the ground away from the foundation.
Thanks,
-Dale

Thanks, to everyone. This has been a long standing problem, and I believe they are seeking a less expensive shortcut . . . probably a waste of money to get htis w/o taking care of the water problem first . . . regardless of the cost. Student health should come first. Thanks for all your help and for further confirmation of a better course of action.
