There was a problem filtering reviews right now. Please try again later.
Every 2-3 months (depending on use), you remove the cartridge, take the top off (it should unscrew), and pour used granules in the trash. Follow the instructions that AOS provides to refill the new granules (its very straightforward).
I always have 1 spare cartridge on hand because you must soak the newly refilled cartridge for 24 hours. If you are fine going a day without your humidifier every 2-3 months then you just need the one cartridge that comes with your AOS.
Thanks for taking the time to read my review, and I hope you found it helpful in making a purchase decision.
Its a real shame because the I thought the humidifier itself was awesome. Now I can't recommend it at all.
The white powder got so bad it was clogging up my furnace filter caking it with it since I have 2 of these humidifiers. I do not know what they changed or why these filters do nothing and now have to use distilled water where last year they were fine.
I even went as far as getting 2 new filters when this first happened thinking I got some defective ones. I did email the company and never even got a response from them, so I would say customer service is not that good either.
I will not go through this next winter and will look for new humidifiers and defiantly will not purchase any of this brand. They sell 2 filters and one is this and one goes in the water tank they claim stops this, but it does not and it a complete waste of money.
These newer BONECO cartridges work better than the older Air-o-swiss ones did. Seems to eliminate most of the white dust associated with using an ultrasonic humidifier. I wonder what that microscopic dust does to our lungs???
And this works on my new 2nd Rowenta humidifier!!
