How to clean the air clean filter
• In general, the filter should be sucked to remove dust in low fan
speed of a vacuum cleaner once every three months.
• If there is heavily grime on the filter, soak the filter in lukewarm
water with neutral detergent diluted 1:500 for 1 to 2 minutes then
wash it.
• Rinse the filter in clean water, then let it dry on the towel in room
temperature.
NOTE
• Do not bend nor give excessive force onto the air clean filter.
• If the filter surface is heavily blocked with dirt or damaged,
replace it with new one. Purchase a replacement filter at your
local dealer. (model CZ-SA1U)
