Standard filters supplied with the PoziDry ProTM are G4 (PM10 filtration) which filter out
many every day pollutants such as pollen & dust.

Under normal conditions; i.e. away from main roads and industrial areas, it is recommended that the filter
is checked annually and cleaned or replaced as necessary.

The filter may be gently cleaned with a vacuum cleaner or washed in a soapy water solution
and allowed to air dry before re-fitting. Do not dry the filter in a tumble dryer.

When re-fitting make sure that the filter is fitted correctly - this will ensure that all the fresh air
entering the dwelling continues to pass through the filter first.
