Long life NANNI air lters require periodic cleaning.
Maintenance of these air lters is very simple. Please
follow the 4 steps below.
Cleaning: Spray liberally the
NANNI cleaner onto both sides
of the lter and let it soak for 10
minutes to loosen dirt. Do not
allow cleaner to dry up on the air
lter.
Rinsing: Wash the lter with
cold water at low pressure on
the outside to flush dirt out of
the lter. Continue rinsing until
removing all traces of cleaner.
You may need to repeat steps 1
and 2 several times.
Drying: After rinsing, shake off
any excess of water and let it
dry naturally. Do not oil the lter
before it is completely dry.
Oiling: Spray oil (Aerosol) evenly
on the crown of each pleat while
maintaining the nozzle at
approximately 8 cm from the
lter. Allow oil to penetrate into
fabric for around 20 minutes.
Respray oil wherever some
white spots are still visible on
sides of the lter until there is a uniform blue color
throughout.
