Filters for PAUL Focus MVHR
A range of filters for PAUL Focus MVHR.
All MVHR systems need 2 filters, 1 for the intake and 1 for the extract air. A G4 filter can be used for both intake and extract, while an F7 filter is suitable for intake only. F7 filters are slightly more expensive but filter finer dust, particles, bacteria and spores out of the incoming air. If you have a frost protection pre-heater, please read our advice page on MVHR filters.
