1. Non laboratory observations made by Georgia-Pacific Hand Drying Choices Comparative analysis with focus on towel vs. most recent air innovation, Dyson Airblade®

2. Non laboratory observations made by Georgia-Pacific Background Towels and forced air dryers are dominant alternatives Hot air dryers are positioned as reducing cost per dry vs towels G-P’s analysis of cost suggests that the cost argument is not valid More important, public health is best served by paper towels – CDC quote: When washing hands with soap and water, dry thoroughly with a disposable towel. Use towel to turn off the faucet (IB) (90-92,94,411). Recommendations and Reports October 25, 2002 / Vol. 51 / No. RR-16: Facilities will serve their clients best when all aspects of impact are factored into this important choice – Cost per dry – Safety in use – Health of clients – Environmental friendliness

3. Non laboratory observations made by Georgia-Pacific Hygiene Considerations Studies also show that the bacteria count in pubic facilities is higher than other public areas because of the combination of moisture, the bodily functions being performed and the fact that not everyone follows a proper hand washing and drying regimen Hot air driers used in public toilet areas tend to circulate the bacteria present in the bathroom These driers heat the bacteria and moisture in the air, incubating more bacteria A person who has just washed their hands is essentially blowing high- bacteria count air onto their wet hands Additionally the driers may or may not have filters to help clean the air being circulated onto ones hands If a filter is contained in the unit, proper maintenance and replacement of these filters may, or may not, be performed properly by the maintenance staff

4. Non laboratory observations made by Georgia-Pacific Observations At GP, we believe that the most hygienic and image-improving system to dry hands is the enMotion® automatic touch free towel dispenser and the Cormatic® Automated touch free towel dispenser. – Reduces consumption – Most hygienic – EPA towel – LEED Credits We purchased a Dyson drier and observed as a minimum of one hundred people tried using it over a 4-day period at an internal business function

5. Non laboratory observations made by Georgia-Pacific The Dyson Airblade Drier The Dyson Airblade drier is being marketed as an improvement to traditional, ‘hot air’ driers and an alternative to paper towels – It uses high velocity air, rather than heat, to blow water off hands – It works more quickly than the traditional driers – It presumably has more hygienic features including: Filter to clean the air going through the unit Anti-microbial coating surface For details, visit: www.dysonairblade.comwww.dysonairblade.com

6. Non laboratory observations made by Georgia-Pacific Top Line Observations SizeThe Dyson Airblade dimensions: Height 25.375 inches Width 12 inches Depth 9.875 inches Weight without electrical cord is listed as 32 pounds PowerSold without an electrical cord NoiseThe unit is loud when it operates CostThe unit cost $1,200 - $1,500; installation can be up to $1,000 or more as each unit requires it’s own 15 amp circuit.

7. Non laboratory observations made by Georgia-Pacific Topline Observations Hygiene/ touchless Although billed as a touchless system, 2/3’s of the users ended up inadvertently touching the unit. This happened when they: Tried to insert and/or draw their hands back out of, the ‘entry way’ at the top of the unit Or because the force of the air blew their hands against the sides of the cavity

8. Non laboratory observations made by Georgia-Pacific Topline Observations Cleanliness & Safety The drier blows the water off hands, into an open trough in the bottom of the unit. There is nowhere for the water to go, so with repeated usage, it collects in the bottom of the unit, and flows down the sides, onto the floor As you will see in this visual, after only 10 hand-dries, water was running down the sides and collecting on a piece of paper

9. Non laboratory observations made by Georgia-Pacific Topline Observations Hygiene/ surfaces The unit claims to have an antimicrobial coating, presumably on surfaces where peoples’ hands might come in contact with the dispenser As mentioned, contact with the unit is likely

10. Non laboratory observations made by Georgia-Pacific Considerations Hygiene & Wellness When presented with the prospect of using an air dryer to dry their hands, many people will either not wash, not dry or both – This results in what is known as a “hygiene failure” – This can potentially result in: A hazardous water puddle developing on the floor, which may result in a “slip and fall” Potential cross contamination as contaminated hands touch surfaces such as door handles, passing germs onto the surface – Further cross contamination as they then come in contact with others in public The Centers for Disease Control and Prevention reports in their document: Recommendations and Reports October 25, 2002 / Vol. 51 / No. RR-16: – When washing hands with soap and water, dry thoroughly with a disposable towel. Use towel to turn off the faucet (IB) (90-92,94,411). This option is non existent when using a dryer

11. Non laboratory observations made by Georgia-Pacific Considerations User preference In a study conducted by Harris Interactive in February of 2009:  Only 17% of participants preferred air dryers to paper towels Study conducted by Harris Interactive February 2009

12. Non laboratory observations made by Georgia-Pacific About 70% of consumers believe Paper Towels to do a better job of drying hands than Air Dryers. Study conducted by Harris Interactive February 2009 How to read this graph: Of people who prefer air dryers, 52% think air dryers do a better job of drying…

13. Non laboratory observations made by Georgia-Pacific Considerations 5 Year Usage Cost/Unit Total acquisition costs, including installation must be considered Dyson Airblade – Cost for unit: $1200 to $1500 – Cost for installation: It is recommended by the manufacturer that each unit is on it’s own 15 amp circuit – not tied into a nearby junction box This type of installation can cost up to $2000/unit in modern office buildings; will use $500/unit for this example If unit is not properly installed according to manufacturers recommendations, it could void the warranty Warranty: 5 year parts and 1 st year labor limited warranty – Cost for actual hand dry may be nominal and therefore will not be considered in this hypothetical scenario

14. Non laboratory observations made by Georgia-Pacific Considerations 5 Year Usage Cost/Unit Dyson Airblade – Total cost for acquisition and installation: ~$1700 – $1700/55,000 hand dries (5 years) = $31.00/1,000 hand dries enMotion® – Average number of towel cases used per dispenser per year: 3 – Example price per case 89460: $51.80 + 5% annual inflationary price increase Total cost for towels over 5 years: 1.Year 1: $154.00; Year 2: $161.70; Year 3: $169.79; Year 4: $178.27; Year 5: $187.19 = $850.95 towel cost 2.Dispenser + installation: $43.00 3.Annual tipping fee (landfill) for this quantity (150 lbs) is nominal as the landfill and transportation cost per ton in Chicago is ~$50 – Total cost for enMotion (1+2+3 above): ~$994.00 – DSL (Dispenser Solutions for a Lifetime) warranty: 5 years – $994/55,000 hand dries (5 years) = $18.00/1,000 hand dries Difference per 1,000 hand dries: – $31.00 - $18.00 = $13.00; $13.00/$18.00 = 72% more to use the Dyson – Break even point for Dyson would 8.5 years – Average cost/year enMotion = $198.80; $1700/$198.80 = 8.5

15. Non laboratory observations made by Georgia-Pacific Hypothetical 5 Year Total Cost Comparison per Unit

16. Non laboratory observations made by Georgia-Pacific Other Potential Costs/Concerns We suggest that a number of the features observed may result in added costs and possible tenant/public dissatisfaction: Clean up of water dripping from unit. Loss of tenant / patron productivity due to slower hand drying – Societal pressure to rush if there is someone waiting Possible dissatisfaction of tenants due to noise, force of air and complexity and time to dry hands while avoiding the sides of the unit The potentially ‘unforeseen’ but very real cost to track, properly maintain and replace the filters for every drier throughout a facility on a regular basis

17. Non laboratory observations made by Georgia-Pacific In conclusion Air dryers should be thoroughly tested by the customer prior to purchase All environments vary, so it’s likely results will as well ALL costs should be carefully considered when making a purchase decision Towels not only provide some hygienic advantages, but may provide significant total cost savings as well.
