Cleaning 

The filter of air conditioner units should be cleaned every 3 months. Newer models tend to be self-cleaning and this function can be activated by using the remote.

CLEAN FILTER: Press [フィルター  掃除  /  ふぃるたーそうじ  /  firuta- souji] to clean the unit’s filters.

INTERNAL CLEANING: Press [内部クリーン /  ないぶくりーん  /  naibu kuri-n; may also be 内部清浄  /  ないぶせいじょう  /  naibu seijou] to clean the unit.

Nevertheless, it is best to manually clean the unit to prevent the buildup of mold, dust, and bacteria. In particular, if you notice an unusual smell coming from your unit, do not hesitate to clean your air conditioner or to contact a repairman as this smell can indicate a buildup of mold.

How to clean your air conditioner

Before cleaning, be sure to have on gloves and a face mask and goggles if available. You will also want a vacuum cleaner and additional plastic bags on standby. Remove furniture or place a tarp over large items. Secure a plastic bag underneath air conditioner unit to catch dust. Open windows as well to let clean air circulate. Turn off power, unplug unit (or turn off breaker is there is no plug), and open the cover. To clean the unit, you may use a vacuum cleaner with a brush attachment, then very gently remove filter.

Place filter inside a plastic bag and use the vacuum cleaner to remove excess dust off filter. When done, use a shower head or hose, to thoroughly clean filter, making sure to spray water on the exterior of the filter. Let air dry, preferably for 24 hours or until completely dry. Once filter is completely dry, insert into unit. Using a damp filter can result in the buildup of mold.

Lastly, you’ll want to clean the outside of the unit by gently wiping with a damp cloth.
