How often do you replace them?

I try to wash them at night when I take them off or in the morning. As long as they are clean when you put them on and they are keeping their shape, I keeping wearing them. I have a spare because I have put mine down when I take my socks off and forget to pick it up. Then in the morning when I go to put it on I forget where I put it. So I use my spare and then I find it. Always put it at a certain place every night so you know where it is. Sometime I go crazy looking for it because I didn't put it where it belongs. Hope this helps.

replacement is not an issue. the material they are made of is a soft gel-like material. it will not deteriorate, and is not affected by moisture.i use mine daily.

I have yet to replace mine. As long as you wash, dry & power them they should last quite a while.

I wear mine every day for hours and have not yet replaced them. They are around a year old.

I have 2 and an original....they all seem to last about the same ...I just change them when they need it and don't keep track or worry about it.....

When I first used them I changed them at 90 days. But over time I noticed that they were not that dirty after 90 & I have left them in longer. I change them three times a year now.

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

They typically last 6 months. It depends on how much you use it. I change mine every 9 months.

We change ours once a year. Not sure if that is what is recommended though...

Sure, you can clean and reuse...in the manual it states that you must replace them every two months

I replace mine about once a month when using the machine. The only reason I can see to replace is that mine get hard water deposits and no longer wick the moisture properly. You may not need to change them as often although eventually they will kind of break down. I am not sure how often the manufacturer recommends replacement. Hope this helps.

I replace mine every year just to be safe. They probably would last a lot longer but I am careful and want things to remaindry.

I replace it once a year but I imagine I will depend on the watter quality in your town. I'm in the south of Spain and we use it a lot.

I think we replace ours every 3-4 months. We watch for wear and tear and any build up in the straws, once we see it we toss them. We use the cups for milk and water only.

I truthfully do not know. I do know that I do not change mine every 6 months. I would think that they last a long time as I have not seen any date on them.

A LONG time. It was years before I had to replace mine, but I don't use it every day. Maybe a couple times a week is all.

I flip mine upside down and back up once every six months to prevent settling. A rule of thumb is you should replace them every seven years or sooner if they indicate they are low.

I do. They work just fine. Depending how much they are used, I change them daily.

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.
