How do I know when to change the filter? Someone else used mine for a year, and now it's quite loud. Is that a sign a new filter is needed?

You can sometimes tell if the filter has reached the end of it's useful life if you see excessive particles floating in the air. Another sign that has been mentioned by Austin Air is that you may notice a sweet smell. To help prolong the life, try removing and vacuuming the prefilter to improve airflow.

I don't think it is the filter, try to remove the filter and put on the machine to see if it changes............usually loud noise is a sign of motor replacement or maybe something happened to the fangood luck.

I've never had this problem with mine. Did you rinse out the filter well before placing it? That's the only thing I can think of that might be the cause...

Make sure the pump is properly seated into its base and the suction cups are properly secured the back. Mine was a little loud as well until I did this. Also if it starts to overflow it's because the filter is dirty

Have you soaked it in cold water for 15 minutes and then scrub it ? Thats what the directions say. Also I know there are some phony filters out there. Where did you get it ? You need to call the filter company if you have tried soaking it etc and they can send you a good one. Hope this helps you.

I changed mine at 3 months, mainly because I noticed by the contents of the bin that the airflow appeared to have decreased slightly. I used to change filters once a month before switching to the purple filters. I highly reccommend the -21 filter and brush upgrades.

I seem to recall that the filter might need to be cleaned. I don't handle this, my roommate does, But I do notice it it smells from time to time. Run it for a while and check it later.

Very good question - there is no way to change the filter so no way to know. We've just kept ours on for years and hope it's still doing the job.

Is this a new filter unit? If it is new, sounds like defective to me. My experience has been that the filters always end up leaking when it is time to replace. Quality of workmanship and design is not directed at longevity.

Honestly it seems like every time you use it the filter gathers dust and you just wipe it off with your hand *Think lint brush here*.As soon as it's clean you're done. in terms of replacing it. Hmmm who knows...seems like it should hold up for quite a long time. If not you can replace it for like $5 on their website or make your own.

What I did was vacuum the actual blue filter thoroughly as it really didn't look very dirty even though I got a "change filter" message. Then I washed the plastic grid piece it fits into thoroughly and let it dry. I reassembled it and still got a change filter message. However, I discovered there is a tiny "reset filter" hole near the top of the inside of the unit where you place the filter. I stuck a paperclip in the hole and pushed, and now it's behaving as if it has a brand new filter! I think maybe if this is done on a regular basis that you can get a lot more use out of this unit, even though the filters are "no longer available."

Did it crack around the threads? Mine did also after a year or so, probably due to me constantly adjusting the angle and maybe hanging or pulling too hard on the head. I patched it for a little longer use and then eventually just bought a new one after a year or so usage. It was time for a new filter anyway and the whole unit is the same price as a replacement filter. GL!

I ordered this replacement and it works http://www.amazon.com/gp/product/B000B8URLI/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1 I have read that you are supposed to replace the filter 1xper year, but who knows what kind of usage they are basing that off of. I replaced mine after only 4 or 5 months (when I started noticing a considerable difference), but I hadn't realized until afterward that you are supposed to reverse the filter every 30 days. I am hoping if I do that it will last at least a few more months this time.

I think that info should be in the instructions the humidifier came with. Im sorry. Our filter does not need changing yet.

After moving the purifier several times while vacuuming, mine has also developed a louder whirring noise. It is obvious at all levels. Level one used to be very quiet, an almost unnoticeable hum, but now it sounds like the motor is grinding and working overtime. As it's been less than a year, maybe less than half a year, I am planning on speaking to the manufacturer about it.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

Sorry Arthur...I think you're right! I ordered a spare filter back in June and thought nothing of it. Then, I went to change my filter this morning and the one they sent me was wrong. My old filter has an opening on both ends and the new one does not. Plus, the part number is different. Maybe it's a new design but I'm not putting it in until I find out. Thanks for making me aware of this. I wouldn't put your's in either. Please let me know if you find something out from the company.
