Replace the inlet tubing
Replace the air inlet tubing regularly to prevent organic growth or

result in false high particle counts.
The manufacturer recommends that the air inlet tubing of typical FMS
installations in life science and pharmaceutical manufacturing clean
rooms be replaced at least once a year.
