LAUSANNE, Switzerland, September 21, 2010 -

    To meet a projected increase in demand, SwissINSO, a leader in
    proprietary solar-energy solutions, has transferred production of its
    100% solar-powered water purification / desalination units to a much
    larger facility.

SwissINSO Holding Inc. (OTCCBB.SWHN) is pleased to announce a
major expansion in production capacity for its Krystall (TM) solar-powered
water purification / desalination units. The new plant in Denges is now close
to SwissINSO's headquarters at the prestigious R&D Science Park at EPFL
(Ecole Polytechnique Federale de Lausanne), the Swiss "Silicon Valley".

"This recent move marks another key milestone in the rapid
growth of SwissINSO, and demonstrates our ability to execute 'on plan'", said
CEO Dr. Yves Ducommun. "We will now benefit from simplified logistics, direct
control of the production cycle, and reductions in delivery time.
Furthermore, we can easily expand this significantly larger production site
once we reach capacity", he added.
