Filter Replacement
The filter of this PIV unit will usually need to be changed every 3-5 years depending on
occupancy, and the type of environment the dwelling is located in (I.e. urban/ rural, and their
associated levels of airborne pollutants).
It is recommended that the filter is visually checked every 12 months.

becomes accessible and may cause injury.
To remove the filter, pull one end over the spigot by stretching the elastic. The filter will come
away easily.
To replace the filter, place one end over the spigot directly next to the supply outlet. Pull the
free end to stretch the elastic over the last spigot, ensuring that all openings are covered by
