How often do these cartridges need to be replaced?

The directions read: "The cartridge must be replaced every 2 to 3 months." Options are to replace only the granules inside the cartridge or to replace the entire cartridge.

For me it's about once a year. Remember that you can save money by just buying replacement crystals and unscrewing and refilling your original cartridge.

Purchased my humidifier in Nov 2014. Cleaned and replaced everything I should EXCEPT I went for value and used the replacement granules rather than buying the whole cartridge. My humidifier hasn't worked right since. The 'refilling' part was easy - really easy but it shuts off and the 'cleaning' light always comes on after a few minutes of use. I called Air-O-Swiss and he suggested taking some of the granules out and I did - still have the same issue. (I did this twice) I'm going to buy the whole replacement cartridge again to see if this fixes the problem - if not I guess I got a crappy unit.

You replace this cartridge when you start getting white dust on things. This is the minerals in your water. As this cartridge gets full of these minerals, it's efficiency goes down. Depending on how hard your water is, this time can vary greatly

Don't know about 20 years ago. Had my previous machine 15 years and it had a replacement ink cartridge. These cartridges last a long time, of course, depending on how much you use the machine.

I'm sorry I'm unable to help you. I returned the item for refund so never had to replace the cartridge.

Karen, I'm sorry I can't give you an exact date because I have thrown away the boxes since I installed my cartridges. I can tell you that I'm almost sure that you are good for at least a year.

It depends on usage. The Everpure website states that they should be replaced once a year. But it also states that they have a 1000 gallon capacity. I take this as meaning replace once per year or every 1000 gallons whichever occurs first.Another indicator that you need to replace the cartridges is when the water flow out of them has diminished significantly.

We had no problems for a few refills then the printer stopped recognizing the cartridges. We have not used the printer other than as a scanner in about a year now. Wish I could actually help.

I've had this problem a couple of times. I have taken the cartridge out and reinstalled it - sometimes several times. Finally I just ignore it. The printer keeps printing. I've used these cartridges several times and they last quite a while. Good cartridges for the price. Just keep printing until the copy gets faint and then change it out.

No. Sorry. I first thought these were really great. They printed just as well as the OEM cartridges. Then they did not last half the time the original ones do. Hate to be the bearer of bad news.

The cartridge is what you replace. It was 40 or 45 dollars each, and didn't last very long.

Not sure exactly, but I rarely replace them, I would say over six months at the very least

Hi John, the cartridge are supposed to be "plug and use", if they are not being recognized by the printer, contact the seller, they should be fine to replace them for you. It happend once to me on one black cartridge, the seller asked me to trash it and he send me a replacement one that worked fine.

These are replacement cartridges. Old one goes out new one goes in. Very simple.

As you say, it depends on the frequency of use. We do not use the printer on a daily basis, but I would say the color cartridges lasted several (3-4?) months. Of course, the black cartridge needs to be replaced more often.

I don't know - we had no trouble with the cartridges, and we go through them so fast I don't even think we still have those to check. Sorry.

I have never checked. I have never had a problem with the cartridges I have purchased.

My pool builder advised us to replace the cartridge every year. I am in Oklahoma and use my pool about 5 months a year if the weather is cooperative. For you I would replace the cartridge once a year unless my pool began showing stress or the weather is unusually crazy. It has made a world of difference in my chlorine pool. Good luck.

Just replaced mine after 2 months but I use printer 5 days per week. So a lot.
