It’s definitely time to clean this air filter
After receiving a question recently about cleaning the Fujitsu’s air filters, I thought I’d better check mine. Good thing – yuck!
Fortunately, a quick spray down in the sink and they’re good as new. Just remember to spray from the back side to blow the gunk out of the filter. Also, let the filters dry out before using them.
In addition to the two large mesh filters, there are a small foam and pleated filter below them. Clean and dry those and you’re good to go.
On my Fujitsu, you can set it so the green light will blink after a certain amount of use, reminding you to change the filter. if you don’t have the install manual, you can probably find it on line. The setup is a little cryptic (designed more for the HVAC folks than the owners) but you can get it set up to remind you. Yeah, your filter looks pretty bad.
Thanks for the tip. I hadn’t seen that option. We can all use little reminders like that to take the guesswork out of things.
Thanks for the tip. I need more help. you say “In addition to the two large mesh filters, there are a small foam and pleated filter below them. Clean and dry those and you’re good to go.” I have an R15RLS-2 now well overdue for filter cleaning but I find my Operating Manual very confusing once I get past the reference to the large washable screen filters. Then I’m told that the Polyphenol Catechin filter UTR-FA 16 should be replaced every three months — “they cannot be washed and reused.” I have searched fruitlessly on the web for replacement filters and come up empty. Can you help clarify the situation?
With thanks, BEWILDERED
Good point! For those wondering what you’re referring to, check this link. And here’s a reference to buying these expensive little filters.
Here’s what Fujitsu says about the filters:
“These systems feature both an Apple-Catechin Filter and an Ion Deodorizing Filter. The Apple-Catechin Filter absorbs dust, mold spores and microorganisms by static electricity. Growth is inhibited and deactivated by the polyphenol ingredient extracted from apples. The Ion Deodorizing Filter deodorizes by powerfully decomposing absorbed odors using the oxidizing and reducing effects of ions generated by the ultra-fine particle ceramic.”
Personally, I’ve never purchased a replacement for this filter, so it’s probably ineffective at this point. At $57, I doubt I will be either!
Thanks for pointing this out – this particular filter can’t be cleaned.
