5Merchants G4 and F7 filter set
$80.00 exc NZ GST
This set includes 1 x F7 Pollen filter (for the intake) and 1 x G4 Filter (for the extract) for the Zehnder ComfoAir ventilation models Q350, Q450, and Q600.
These 5Merchants filters are the same high-quality filters as the Zehnder brand, and function and fit the same, just at a more affordable price.
Filters should be inspected monthly and given a light vacuum to remove dirt and dust. Filters will eventually become blocked with residual debris and should then be replaced. Typically, blocking will occur every 6 - 12 months depending on the location (near busy roads or inner city areas tend to block more quickly than remote country settings).
