ARIZONA ENVIRONMENTAL TECHNOLOGIES DELIVERS INVESTOR UPDATE ON COMPUTER ANTI-THEFT DEVICE PROJECT AND DISCUSSES MARKET AWARENESS OF COMPUTER THEFT ISSUE Portfolio HomeHeightened Awareness of Computer Data Theft Spurs Interest in EMTI's Computer-Guard(TM)

TUCSON, AZ, Jun 28, 2005 (MARKET WIRE via COMTEX) --
Environmental Technologies International, Inc. (OTC: EMTI) is pleased to announce that it continues to achieve progress towards bringing to commercialization both its Computer-Guard(TM) computer security device (www.computer-guard.com) and its hi-tech, AWE indoor environment 'HVAC' system.

RESPONSE TO SHAREHOLDER ENQUIRIES

In response to many shareholder enquires as to the reasons for the upward move in the Company's share price on abnormally high volume recently, we can only attribute this positive activity to perhaps a growing awareness of the progress being achieved by the Company, as well as a general market response to the low price levels reached by the shares in recent months.

COMPUTER DATA THEFT

Several high-profile cases of computer data theft have dominated news headlines recently, driving home the seriousness of this growing crime and the critical need for individuals to alleviate their personal computer security concerns by doing all they can to protect their data.

More people than ever now have anti-virus software and firewall software installed, which provides a high level of protection of their pc data from surreptitious cyberspace 'operators.'

However, having data stolen directly from your desktop computer at the office or in the home, by use of the ubiquitous USB Memory Keys or 'Thumb Drives' continues to represent a very real threat. By using one of these memory devices, someone can download large amounts of valuable information from your desktop computer in a matter of minutes while you are 'out to lunch' or away from your desk for any reason.

Computer-Guard(TM) Provides The Protection You Need

Essentially, the Computer-Guard(TM) system protects the user's information by rendering the computer useless whenever the authorized user is away from the machine. A low price and ease-of-use are expected to meet with an enthusiastic reception from the huge and growing computer-safety market.

In recent weeks, the Company has received numerous enquiries from potential distributors for offshore markets, and the ongoing marketing launch is expected to include several of these. While the product launch has suffered some of the usual delays encountered in such projects, management is confident that meaningful Computer-Guard(TM) sales will be achieved in the foreseeable future.

In compliance with the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995, EMTI notes that statements contained in this announcement that are not historical facts may be forward-looking statements that are subject to a variety of risks and uncertainties. Accordingly, EMTI wishes to caution readers of this announcement that its future actual results may differ materially from those that any forward-looking statements may imply.
