NOTICE
Used filters
It is not advisable to fit filters again that have already been used. If you do want to refit a
filter you have removed, remember the direction in which the fan draws air into the device.
Make absolutely certain that you do not fit the outer side of the filter on the inside.
Generally, the outer side is much more dirty than inner side if it has been in use for some
time.
