A particle-free cleanroom does not always mean a contaminant-free cleanroom π§ͺ .
HEPA and ULPA filters are highly effective at capturing dust, fibres, aerosols, and microscopic airborne particles, helping maintain strict cleanroom air cleanliness π¨ .
However, gases and chemical vapours can pass through conventional particle filters because they exist at the molecular level π«οΈ .
These airborne molecular contaminants (AMC) may include acids, bases, organic compounds, odours, dopants, and other harmful gases that can affect sensitive manufacturing processes βοΈ .
That is why many critical environments rely on molecular filtration to complement particle filtration. Specialized chemical media are selected based on the specific contaminants present, providing targeted gas-phase contaminant removal π± .
A comprehensive cleanroom filtration strategy addresses both particles and molecules, helping improve process stability, product quality, and equipment protection π .
Because truly clean air means controlling both the contaminants you can see and the ones you cannot β¨ .
