The unseen impact of air conditioners on fiscal and physical health.

1. THE UNSEEN IMPACT
OF AIR CONDITIONERS
ON FISCAL AND
PHYSICAL HEALTH.

4. The culprit is biofilm.
A harmful, tenacious microbial
matrix that thrives in all HVAC.

5. Chemical cleaning doesn’t get rid of it.

6. Chemical cleaning doesn’t get rid of it.
 Chemicals are toxic and temporary
 Don’t reach build-up in deeper areas
 Mold doubles every 2-6 hours
 Bacteria doubles every 20 minutes

7. Biofilm makes air handlers
work harder.
 Impedes air flow
 Reduces heat exchange efficiency
 Cuts cooling capacity

8. Result: Lower performance
and shorter equipment life.

9. As biofilm builds up, so do energy costs.

10. Now let’s talk about
the human costs.

11. Harmful organisms in biofilm detach
and enter the air stream.

12. Studies link asthma, allergies and
disease to microorganisms in biofilm.
Including pathogens
implicated in Hospital
Acquired Infections

13. Bad Indoor Air Quality (IAQ) is costly
for every type of facility.
 Hospitals: from
reimbursements to ratings
 Schools: absenteeism
reduces funding
 Food manufacturing:
food safety
 All buildings:
productivity; liability

14. Steril-Aire UVGI: the simple,
sustainable, affordable solution.

15. Our system installed in HVAC gets rid
of biofilm quickly and continuously.

18. How it works: the right dose of
germicidal UVC in the right places.
 UVC radiation destroys ability of
microbial DNA to replicate
 The right intensity of UVC light in the
right places (HVAC coils, drain pans)
18

19. Steril-Aire is integral to
infection prevention strategies
at leading hospitals.
 Air conditioner: largest single reservoir of
microorganisms associated with Hospital Acquired
Infections, from Pseudomonas bacteria to mold.
 Steril-Aire: clinically validated solution.

20. Case studies: payback from
operational savings. Better IAQ
essentially “free.”
 “A $25,000 investment eradicated microbes in HVAC
and yielded $850,000 in clinical savings”
Children’s Hospital of Buffalo
 “In one year, a $250,000 investment saved $500,000
in annual energy and equipment sustainability”
Rio Grande Hospital, Texas

21. Case studies: payback from
operational savings. Better IAQ
essentially “free.”
Food industry: Steril-Aire UVC for HVAC - food safety
A major U.S. cereal manufacturer achieved substantial reductions
in operational costs while eliminating airborne contamination and
improving food safety.

22. Case studies: payback from
operational savings. Better IAQ
essentially “free.”

Educational institutions: reducing absenteeism
Funding for many schools is tied to attendance.
University of New Mexico saved $500,000 in coil replacement
costs and $61,945 in annual energy costs. Destruction of allergy-
and disease-causing microorganisms in HVAC improved IAQ.

23. How clean does your air need to be?
23
 A hospital neo-natal ward requires more microwatts and
higher continuous intensity than an office building
 We engineer systems to meet your objectives

24. Steril-Aire achieves target “energy
field” with fewer emitters.
24
 Steril-Aire emitters: patented design for higher
sustained output over longer period in cool HVAC
conditions
 Higher value, lower total installed cost

25. The first step: field evaluation.
25
 Assessment: cultures from HVAC components.
 System engineering: energy requirement based
on scope of the problem and facility’s goals

No more toxic, costly and ineffective
chemical cleaning
Reduced liability from illness caused by
HVAC-bred microbes.
Air handlers run more efficiently and
last longer.
Savings of 15% to 30% on energy bill.
