Your filter should match the application it is being used for.

For example, if you are in a pharmaceutical laboratory you would be more likely to require a HEPA filter for removing 99.997% of contaminants as opposed to a G4 panel which removes approx. 90%. Yet if you needed to remove larger particles, for example pollen then a HEPA filter would be a less cost effective

Our particle filter selection guide is a handy way to pin-point the filtration level you require. If you need further information to narrow down your search why not get in touch with our Technical Sales Team?
