Have you ever wondered how the International Space Station keeps its air pure?
After all, they can not open a window and let fresh air in. There are commercial and home air purifier units that us NASA-licensed technology. For more information, check out http://www.indoorps.com/nasasecret1.html
We've improved the Air Quality of My Dental Office using the Same Technology that NASA uses to keep the Air Pure in the Space Shuttle and International Space Station!
As many of you know, my dental assistant Angie and I both have seasonal allergies that were terribly severe this spring. While we have a Sharper Image electrostatic filter in the reception area, an Oreck electrostatic filter in the staff office, as well as a good filter on the air conditioning unit that is changed frequently, it was not enough.
While trying to do more research on "is there anything more I can do to filter the air we breath in the office," I stumbled upon information from Will Smith (no, not the Academy Award winning actor). Will spent his professional life in the air quality field. He had the experience and has the professional credentials concerning improving air quality in the industrial arena and now consults with people to improve their home and office environments.
As a Dentist, I have always been concerned about cross contamination, and my patients know the lengths that the staff and I go to sterilize all handpieces and instruments, and to clean and disinfect all surfaces between patients. Air-borne bacteria and viruses have always been a concern as well, so we decided to do something about it by bringing in this NASA Technology. We went about testing it with a simple experiment that surprised even me!
The first thing we did was to test the air (before the Air Purifier arrived) with a simple Petri Dish test. We placed sterile medium in the petri dish and let it gel. We then exposed it to the air in the Dental Office for 1-hour and after only one day we saw growth of both bacteria and mold/fungus:
Below is the April 24th photo of one day's growth - 24 hours after exposure.



By that Friday, we had received the small toaster-sized air purifier, recommended for my office situation by Will Smith. We placed it in the area where air enters the air conditioner and turned it on. We left the air circulating over the weekend and noticed a fresher smell to the office when we returned on Monday.
To paraphrase some of the literature I read that tells it like it is:
"It's not whether you will breath purified air or not -- either it gets purified before you breath it into your nose and lungs; or your nose, throat and lungs will filter it and purify it before it reaches your blood."
