SEATTLE, May 31, 2011 -

HaloSource, Inc. ("HaloSource" or "the Company") (HAL.LN, HALO.LN) the
clean water and antimicrobial technology company, today announces that it has
established HaloSource Water Purification Importações Ltda, a wholly owned
Brazilian subsidiary of the Company to manufacture, import and distribute its
HaloPure(R) powered components, cartridges and devices for partners in
Brazil.

The Company has also appointed Luiz Cintra as Managing Director of its
Brazilian subsidiary. A Brazilian native, Luiz has particular knowledge of
the market and has previously worked with the Chief Executive of HaloSource,
John Kaestle.

The opportunity for HaloSource in Brazil is sizeable. The Latin American
market household water purification was estimated at $400m, growing at an
annual rate of 15 per cent, according to research published by Frost &
Sullivan in 2005.

John Kaestle, Chief Executive of HaloSource, commented: "The
establishment of HaloSource Water Purification Importações Ltda enables us to
work much more efficiently with our increasing number of Brazilian partners
to supply the growing consumer market with water purification products. Luiz
Cintra
is a former colleague of mine and I am delighted that he has agreed to
lead the charge for us in Brazil. We can now look forward to supplying the
domestic market with pure water at point-of-use."

In 2009, HaloPure(R) became the first new drinking water technology in 30
years to be granted both Manufacture-For-Use and Device registrations by the
United States Environmental Protection Agency (USEPA), widely recognized as
having the world's most stringent performance requirements for water
purification. In 2011, China's Ministry of Health issued formal approval of
HaloPure(R) (2011-0064) under a new process developed to ensure the safety
and efficacy of new technologies employed in products that impact human
health. HaloPure(R) is the first new drinking water purification technology
to be approved under these standards. In Brazil, the Company expects that
HaloPure(R) products will meet or exceed all appropriate standards of the
National Institute of Metrology, Standardization and Industrial Quality
(INMETRO).

HaloPure(R) is a unique contact biocide technology that is proven to
attack and kill a wide range of harmful microorganisms and is approved for
long-term use in a variety of markets, including the United States.
