Terrible substitute

Reviewed in the United States on January 24, 2017

Size: 1 PackVerified 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.

Change Cartridge/Material as Recommended

Reviewed in the United States on August 2, 2017

Size: 1 PackVerified Purchase

This worked perfectly with my Air O Swiss. For like three years I didn't even realize this thing needed to be changed; I thought it was just the hydro cell that needed changing. When I switched out my old cartridge the material inside had turned green! You definitely need to be changing this cartridge! Will be doing so every 2 months as recommended. I am going to look into whether or not they sell the refill material so I can just switch that out instead of buying a whole new cartridge so it's less waste. But after so long with the old cartridge I definitely needed a fresh one.

Does not fit Air-O-Swiss Model U 7142! No Way!

Reviewed in the United States on October 20, 2018

Size: 1 PackVerified Purchase

It is advertised as fitting all models but 7146. I have Air-O-Swiss (BONECO) Model U7142. The cartridge diameter is about 3/4 inch smaller than the threaded end of the reservoir. How is that supposed to fit?
Customer service from BONECO nearly impossible to find.
Expected better from Swiss manufacturer.

These things always clog.

Reviewed in the United States on January 23, 2014

Size: 1 PackVerified Purchase

We had two Air-O-Swiss mist humidifiers during the last several years. I got fed up with the demineralization cartridges always clogging. We had to continually monitor the humidifier to make certain that it was misting. If it wasn't, we had to "jog" the tank to shift the little beads in the cartridge. Although I tried refilling the cartridges on my own at first, this proved such a tedious task, and one that didn't always work, that we had to resort to buying new cartridges every time it was time to replace them. When I tried to set up the humidifier this year, and the brand new cartridge failed to work at all, we replaced the humidifier with a different brand--one that just works without any mess, pain, or fuss. I will never again buy Air-O-Swiss.

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

Reviewed in the United States on April 9, 2017

Size: 1 PackVerified 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.

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.

Another part of the Air-O-Swiss humidifier

Reviewed in the United States on March 5, 2014

Size: 1 PackVerified Purchase

This is another replacement part for the Air-O-Swiss humidifier system. It is essential to have this component installed properly, or the humidifier simply will not work. The part has to be soaked in water 24 hours before using it, and you can refill it with granules that you can buy separately, to save money.

This part should be changed at least every six months, or every season when you use just the humidifier. I highly recommend this part, which is relatively inexpensive, and ships quickly from Amazon.

no idea if it really works

Reviewed in the United States on August 14, 2017

Size: 1 PackVerified Purchase

I really can't tell if it's working because I still see white powdery residue. I guess it would be much worse if I didn't have the cartridge, but I don't know.

Definitely a must buy for your humidifier.

Reviewed in Canada on February 21, 2018

Essential for your Boneco humidifier. Definitely purchase a couple of spares when you buy your unit.

Price was better than retail, and delivery was quick and painless.

Boneco should sell these for less as expecting someone to change the Demineralization cartridge and Hydro cell every 2-3 months

Reviewed in Canada on December 4, 2016

Size: 1 PackVerified Purchase

Works as advertised. Could be cheaper. Boneco should sell these for less as expecting someone to change the Demineralization cartridge and Hydro cell every 2-3 months at $30($20 for cartridge + $10 for hydro cell) means cost of ownership is like $60 for the six months of cooler/dryer weather.

Worth just replacing, refilling is tedious and it's easy to break the membrane

Reviewed in Canada on March 29, 2017

Size: 1 PackVerified Purchase

You can buy refills of the granules but it is difficult to change and the savings are not worth it in my opinion. Product does a good job of reducing mineral output in the mist and minimizing bacteria in the humidifier.
