Protecting the Hubble Telescope from Microscopic Risks
When the roof of the Hubble Space Telescope Cleanroom was in need of repairs, NASA knew it could put highly sensitive instrumentation at risk. They needed something stronger than a HEPA filter — so they looked to Purafil. We created an innovative Purafilter to scrub even the most microscopic particulates from the air, protecting their equipment from exposure and corrosion
Protect your space with NASA-worthy technology.
