The most common complication of hospital care

1 in 20
hospitalized patients
will contract a HAI
(AHRQ 2009; Martone 1992)

Complications add significant health care expenses

  • Each infection ~$23,000
  • Annual expenses per hospital ~$7,000,000
  • $45 billion dollar healthcare problem

Clear limitations exist with today’s tools and technologies for disinfection

  • Everything is done by hand
  • Thousands of surfaces, never enough time
  • No room for human error in patient care

industry knowledge lends deeper appreciation for

healthcare’s micro challenges

Cause and effect: Contaminated surfaces have two modes of compromising patient care

Type of Bacterium
Duration of persistence (range)
Clostridium difficile (spores)
5 months
Enterococcus spp. Including VRE and VSE
5 days – 4months
Staphylococcus aureus, including MRSA
7 days – 7 months

why healthcare is in need of a solution

Clinical Burden

  • Increased pathogen resistance to antibiotics and cleaning agents
  • Surfaces remain contaminated for months at a time
  • PurpleSun’s full exposure of target areas with light provides little to no shadowing to ensure complete disinfection and no pathogen resistance

Patient Perception

  • New health laws (section 2819) require hospitals to publicly report on performance
  • The choice of where to receive care is at the discretion of the patient
  • PurpleSun promotes patient safety through the highest quality in environmental and medical equipment disinfection

Financial Burden

  • HAIs add significant costs and ~8-19 days to average length of stay
  • Medicare reimbursement will be withheld from the hospitals with the highest HAIs (average penalty >$438,000/hospital/year)
  • PurpleSun offers the opportunity for improved quality, and savings in time and materials

How can we accomplish our vision together?

advantages unique to PurpleSun


Physics based model

One of a kind platform for light delivery

The medium for disinfection is light

Produced by the sun, ultraviolet-C is a safe and effective technology within the right application.

Reaching the next level of environmental hygiene

Stepping back and looking at the challenges from a macro perspective, it is clear that hospitals have limited infrastructure, staff and resources, but an ever growing population and rates of admissions. How do we maintain a high level of quality for patient care and the environment when we are solely reliant on yesterday’s limited technologies? A faster, easier, better, automated solution is needed and this is where PurpleSun will help the industry reach the next level.

Invitro Data: Eradication of Medically Important Multidrug Resistant Bacteria and Fungi

  • Kills all clinically relevant multidrug resistant organisms
  • Germicidal performance demonstrates reproducibility and reliability
  • Data showed rapid kill of organisms independent of inoculum load


Clinical Data: Disinfection of Medical Equipment and Surfaces using a Novel Focused Multivector Light System

(no prior mechanical cleaning performed)

  • 32 patient rooms
  • 250 objects
  • 1,500 culture samples
  • Triplicate sampling pre and post 90 second FMUV cycles



Building Partnerships,
Building Value

One of our most valuable traits as a company is the ability to build strong and lasting relationships. With these capabilities, we believe in working together every step of the way. When we commit to a strategic path and partnership, we maximize and deliver on our promises – always.
