Warderly’s Commitment

• Warderly has a strong commitment to improve indoor air quality

• Invented the Air-to-Air Heat Recovery Ventilator in 2001/2002 and obtained patent in the PRC(2002), Hong Kong(2003) and the U.S.(2004)

• During the SARS period in 2003, Warderly considered the possibilities of effective sterilization of bacteria and viruses

• Warderly partnered with City University of Hong Kong to develop an Ozone-based apparatus for improving indoor air quality

• Over 2 years of R&D, the first prototype of Anti-Virus Ozone Ventilator was developed in April 2005

• The Anti-Virus Ozone Ventilator obtained international safety standards: GS, EMC and CE in 2005 and passed preliminary examination for invention patent in PRC

• The Anti-Virus Ozone Ventilator will be globally launched in December 2005

AVO Design Philosophy

• To bring forest into indoor environment

• Effective within the ENTIRE specific area, not locally

• System harmless to human, animals & plants

• Use most reliable and safe technology

• Avoid use of any potential hazard material

• Self-checking, build in intelligence

• Multiple function

• User friendly

• Globally affordable price

• Globally acceptable technology

• Patent protection

Health Concern

Rising health concerns trigger Warderly / Newstart to look for the best solutions to improve indoor air quality

• Human infection with bird flu viruses occurred since 1997 More than 130 confirmed human cases has recorded in

South East Asia which caused a number of 67 deaths1

• The SARS outbreak during 2003 Recorded 774 deaths out of 8,096 cases2

Why use Ozone

• Exist in nature, in forest and good for health if concentration is low

• Even excessive, no record has shown that people died of ozone

• Unlike other chemical, it has no long term effect

• Most basic oxidizing agent, even better than bleach or chlorine

• Change back to oxygen less than 30 minutes, will not accumulate if use correctly

• Almost zero maintenance

• Can react with a lot of hazard chemical and the reaction and by product is totally harmless

• Cheap, basic and use widely in Japan

11

Ozone Level International Standards

• According to various studies conducted by different developed countries, the recommended ozone level in an indoor environment ranging from 0.05 ppm to 0.10 ppm

Countries Authorities Recommendations

US Food and Drug Administration Ozone output of indoor medical devices to be no more than 0.05 ppm3

Occupational Safety and Health Administration

Not be exposed to an average concentration of more than 0.10 ppm for 8 hours4

Environmental Protection Agency maximum 8 hour average outdoor concentration of 0.08 ppm5

UK Department for Environment, Food and Rural Affairs

Ozone level of 50 ppb as a running 8-hour average6

Japan A maximum of 0.10 ppm at any time

Common design fault with O3

• Problem

– Can’t control ozone level

– Release NO2

– Emission of O+ ion

– Lack of O3 sensor

– Poor coverage

– Lack of knowledge

– Incorrect concept

– Incorrect interpret as pollutant

13

AVO Ventilator Technology

• Build in high precision ozone sensor

• Build in CPU for intelligent control

• Build in humidity sensing for best performance

• Build in temperature sensor for best PCT temperature control

• Build in feedback control algorithm for entire system design

• Build in –ve ion emitter

• Innovative ozone plate design with extremely low NO2 emission

• Spiral wind flow design for best ozone distribution

• Simultaneous –ve ion & ozone emission to reduce O+ ion

• Simultaneous O- ion emission for better healthy consideration

AVO Ventilator’s Distinctive Features

• The World’s First Anti-Virus Machine that can effectively regulate the ozone at a level of 0.05 ppm such that ozone can attack virus and bacteria shell, by mean of oxidation, to reduce its infection capability

• Spiral Wind direction at different angles to allow clean and fresh air reach every corner, to ensure even distribution of ozone at an enclosed environment

• O- ion good for human health

16

Advantages of AVO

• Ozone is 100% harmless to human when used within safety limit, e.g. 0.08ppm suggested by EPA of USA or 0.05ppm for Europe & British standard

• Neutralize indoor hazard substance or gas with ozone e.g. Formaldehyde, ammonia, etc

• Neutralize substance is totally harmless

• Ozone attack, by means of oxidation, virus or bacteria shell to reduce its infection capability

• Ozone in spiral air flow is similar like using 1:99 bleach water with cloth

• O-ion can improve the health of living organism

• Resolve the problem of being locally effective

• Build in alarm for fault detection

• Multiple function: fan, -ve ion machine, ozone generator, etc

Comparison with Existing IAQ Improvement Devices

Methods Functions Weaknesses

Filter HEPA Filter out 99.97% of poisonous gas and odor

Cannot reduce bacteria growth

Poor air flow

UV Light Terminate mold, pollen, some bacteria

Cause serious skin diseases

May convert to harmful state

Titanium Oxide Reduce concentrations of airborne pollutants

For sterilizing, deodorizing and anti-fouling properties

Risk of unstable UV level

Lack of long term testing

Thermal High temperature to boil up all kinds of bacteria

Very poor effect

18

Methods Functions Weaknesses

Electricity Kill up to 99.9% of bacteria Kill good bacteria as well

Ionizer Force particulates to land

Purify air

“Re-suspenable Effect”

Exceeding number of ions can cause soar throat and headache

Ozone Reduce bacteria and virus infection capabilities

Inactivate allergens

Difficult to control

Require good circulation

High level of ozone cause respiratory problems
