9.1 Filters
The MVHR should never be operated without Filters. However, depending on the actual volume of contaminants in
the environment, the MVHR Filters need to be checked and cleaned at least twice a year and replaced at least on an
annual basis. The original external / exhaust air Filters contain G4 Filter fibre enclosed in a cardboard frame.
Replacement G4 Filters are of a frameless construction. Contact details for purchasing new Filters or servicing by
Xpelair approved technicians can be found on the back of this booklet.
