Cleanroom Design & Validation to ISO Standards

Who Are We?


ISO Cleanroom was set up by the founder, Toni Horsfield to plug a gap in the market for simple, honest cleanroom support.


"It has been my experience that if you mention the word cleanroom the price for almost every component part doubles. There is always a lot of justification but I believe that the principles of good cleanroom design are relatively straight forward." - Toni Horsfield, ISO Cleanroom.


Toni is a designer with 22 years’ experience in commercial design. In 2013 she took over the Clean Tent product line for Moorfield Nanotechnology with the brief to grow the division for sale over a 5 year period. Moorfield Nanotechnology and Clean Environments was sold to Judges Scientific PLC in December 2019.
