how long does the cartridge last?

They say the cartridge lasts for approx. 100,000 gallons. It is adjustable, though, so your mileage may vary some. I opened mine up slightly (so it will get used up faster) and I've found that it lasts between 4-5 months. That's with 2 showers a day, on average, sometimes a third.

They usually can last a year.....but I personally notice a difference after 6 months.

Mine last about 4 months but it really depends on how much you use your shower

We have a family of four with one bathroom "shower" so I feel like the cartridge was showing it's time after ten months. I hope this helps some?

I haven't had to buy any replacement cartridges yet. I've had mine for several months, using it a couple times a week.

Sorry I can't really give you much of a time estimate but I can say I have not been disappointed. I don't use mine all the time. I go in spurts. I'll use it daily for a few weeks then not at all for months but so far I have not finshed one cartridge yet. Some advice though, try to turn it off while you brush and style your hair then back on as needed. It doesn't take long at all to heat up and saves the cell.

my printing needs are only house hold domestic I can not answer the longevity of the cartridge I am a new customer to this brand and just started using it.

I never look at that. Besides, a cartridge can last a long time in a printer anyway. Its a genuine HP cartridge and works great.

Hi, I can't say I've actually ever counted. What I can say is that these last 3-4 times as long; minimum. It seemed I was always changing cartridges before, and now very seldom. Hope this helps! CE

You should replace the Cartridge. You can get it on Amazon for $11 or less. One cartridge would work well for 2 months (approx). Hope this helps!

I'm not able to answer your question at this time . I only started using the cartridges very recently. I can tell you that up to this point the product is brand worthy and I have been satisfied. Hope this is of some assistance.

When you are done you have to buy a new cartridge. The cartridges last for months.

As far as I can tell, I got these 25 May 2013. I posted my review 27 June 2013, and if memory serves, I installed two of the color cartridges not long before that, so at the time of installation I had probably had them about a month. I have no complaints. I would assume since they sell quite a few in a package, they don't expect them to dry up very quickly, and I believe I saw that they come with a 1-year guarantee. Hope this helps.

not very long depending on how much you print... I PRINT ALOT AND GO THRU A CARTRIDGE OF EACH A WEEK. AND THE REFILL INK IS TERRIBLE

It comes with one cartridge. It is supposed to last up to 6 months, but that depends on the quality of the water in your area.

They seem to last a long time. I use mine in the shower, so I usually clean iTunes running water, then just put it in the cradle for the dry cycle. Occasionally I run it through the cleaning cycle, and the cartridges are lasting about 4-5 months each.

Will last a good 2 or 3 years before renewing, there great! the expiration date should be on the cartridge, mine is.....

Try to replace the chip (as a counter). That may help to extend the cartridge life.

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.

To my knowledge, toner will remain usable for a very long time, assuming there are no drastic changes in humidity where the printer is located. My first cartridge lasted 9 months with infrequent use.
