Long life NANNI air filters require periodic cleaning.
Maintenance of these air filters is very simple. Please
follow the 4 steps below.
Cleaning: Spray liberally the
NANNI cleaner onto both sides of
the filter and let it soak for 10
minutes to loosen dirt. Do not
allow cleaner to dry up on the air
filter.
Rinsing: Wash the filter with cold
water at low pressure on the
outside to flush dirt out of the
filter. 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 filter
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 filter.
Allow oil to penetrate into fabric
for around 20 minutes. Respray oil
wherever some white spots are
still visible on sides of the filter
until there is a uniform blue color
throughout.
