You only need two of these, you should be using the refill granules.

November 16, 2012

Verified Purchase

Do not pay more for to replace the full cartridge every time. One comes with your Air-O-Swiss (AOS), buy 1 more CARTRIDGE here and you are set. AOS sells demineralization GRANULES without the cartridge. Once you have two CARTRIDGES, just buy the GRANULES. It cuts down on plastic waste and will save you a ton on the refills. This is something AOS condones and it does not void your machine's warranty.

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.

This cartridge is made by the Boneco company that took ...

January 7, 2016

Verified Purchase

This cartridge is made by the Boneco company that took over Air-O-Swiss. The original Air-O-Swiss manufactured cartridge was made with some silver to prevent algae/mold/mildew in the water reservior. It was marked with "Ag" which is the chemical designation for silver. This Boneco cartridge was marked with "Na" which is the chemical designation for sodium. When I asked Boneco about it - they claimed that the "Na" stood for "not applicable" - yeah...right... It's printed in the same position on the outside of the cartridge as the "Ag" was printed on the Air-O-Swiss made cartridge. I wrote them stating that I did not appreciate paying for silver and getting no silver since the price of the old and new cartridge are the same. Also carrying over from the old cartridge is the exact same name and part number as the old silver containing cartridge. "Air-O-Swiss AOS 7531" So I tried the new Boneco cartridge and now the water and it's reservoir smell very musty. Boneco claimed the beads inside the cartridge are exactly the same...

Terrible substitute

January 24, 2017

Verified Purchase

The original filters from 2 years ago had a silver based anti-algae agent. This new filter with the "Ag+" marked on the side has a mess of fungus or algae growing within 2 weeks. I'm switching back to my Ag+ filter even if it does leave a bit of white dust on everything. Better than bacteria and algae spewing throughout the room.
Its a real shame because the I thought the humidifier itself was awesome. Now I can't recommend it at all.

Doesn't Last Long With Hard Water

January 4, 2016

Verified Purchase

Just to provide an illustration of the warning that "hard water usage may require more frequent replacement," I live in the Los Angeles area where our city water is fairly hard, and these cartridges only last about three weeks before the white dust returns (I faithfully follow the soaking instructions each time). The humidifier is used in our bedroom and only at night. So, don't expect these to last 2-3 months as advertised unless your water is on the soft side.

February 20, 2017

Verified Purchase

JUNK!!!!!!! Got these humidifiers last year and the filters worked and did not have that white powder anywhere. Now I see that Air-O-Swiss sold out to Boneco and I have this white powder everywhere. I followed instructions like they say to let the filter sit in water for 24 hours, so someone from the company cannot say I did anything wrong.

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.

Gross! This is nothing like the Air O Swiss cartridges we have been using, but ran out of... Arrived wet in an old dusty bent box... looks used and resealed. Returned!!

Removes white dust, gas burns bluer :) New Boneco is better! And will work on Rowenta also!!

January 10, 2015

Verified Purchase

Got rid of white dust production, and now my gas burns a lot bluer! One odd thing about these humidifiers is that when they are putting out the white dust it effects the combustion of an open gas flame. It turns it from a complete blue to a yellow/orange flame. When I first saw this I called my local gas company, they sent out a tech, and after he checked all my appliances and furnace he came upstairs and saw the humidifier. His exact words were "that's your problem".....not that it really is a safety issue...I just thought I had "dirty" gas.

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!!

A new cartridge works great. Don't understand why the refill packages don't

April 9, 2017

Verified Purchase

A new cartridge works great. Don't understand why the refill packages don't. The refill material keeps coming out of the cartridge after being refilled. Appears the goal is to sell new cartridges at a much higher cost.

Love boneco

We absolutely love our boneco and these filters are super easy to put in. I do take it out for the weekly cleaning of the humidifier but otherwise just leave it in all the time.

I wish I knew this before spending unnecessary excessive money for a product that has been replaced

There is a new demineralization and water purifier for all boneco humidifiers. I wish I knew this before spending unnecessary excessive money for a product that has been replaced.

Seems like a scam to me.

If you look carefully at this, you can see the water passes straight through the middle without passing through the demineralization pellets.Read more
