It depends on how abrasive you like the feel of it. If you like it very abrasive, I'd say monthly. You really need to try it for yourself.

It depends on how much you use it, but I can get several months of use without any need to replace it.

I only use it once a week. I haven't purchased a new one yet. I would guess approximate 6 to 8 weeks.

Tje recommendation is every 3 months. Supposedly, there is a wear line or something that will tell you. I plan on replacing mine every 4 months or so. Hope this helps!

Sorry you are having problems. I have used mine 2 to 3 times a week for the last 4 months with no problems. I am very happy with this product.

I change mine every 6 months but it depends on the hardness of your water. The filter can not be serviced. I usually recycle it with my plastics.

Are you asking how often I personally use the one I purchased or are you asking how used is one that's being sold "used"?

You need to replace it every 2-3 weeks or things get a bit too funky. Fantastic product - although I recommend Fresh Patch brand. It lasts longer.

No, you will need to replace it with a new one. But depending on how heavy the use is, one can last at least a year.

I don't remember the last time I replaced one, so I'd guess at least one year.

Mine only has a one year warranty-- but I will be very disappointed if it needs replacing once a year.

How often to replace is a function of air quality. THey need to be periodically checked for mold or dirt then you will know when to replace.

I've purchased mine a few years ago and still good for me and was regularly used. I have not replaced so far.

A few weeks, I think they suggest replacing it every two weeks, but I've used it for six weeks with no complaints from my pup. Depends on weather and usage I would guess also.

I am not certain, but I have used it before and replace it once a year. It did not seem overly dirty when I replaced and probably could have stretched the use even longer.

There is a cartridge that can be replaced, I don't know how often it needs to be done! I haven't had mine long enough!

I replaced mine when it was not working anymore. Otherwise if it's cleaned well, you don't need to replace it often or at all.
