I have had mine for more than five years. It has shown no wearing down at all. I am very happy with it.

There is no wear indicator, but it's a very high quality product. We use it regularly and I don't see us needing to replace for a long time.

We have been using ours for only one month now. There is no sign if wear yet. Seems like they will last for maybe 3 or 4 months.

Only as they wear out. If they no longer fit good or are performing good then replace them. Other than that they don't need to be replaced very often at all. The valves do have a tendency to wear out quicker than others.

It depends on how much you use it. Mine lasted a lot longer than 2 years. But I used it even after they become somewhat worn. The replacements were very easy to install and work great.

When I got mine they were already lifting so I wasn't to happy however I have had mine for 4 months and they don't even look like they are starting to wear. So I'm not sure how long it last but I wouldn't be worried about it since that was one of my worries too.

Well, that all depends on your usage... I have used one of these weekly for about 5 yrs and it shows no sign of wearing out.

It all depends on how much you use them, but for me i use them everyday with high dust content so I replace them every few months

These units must be replaced within 5 years of the manufactured date sticker on the back. And they do fail. Mine did in 3 years.

Also, I had to replace them after about 2 months..didn't hold up..the fit was tight in some areas and loosely fitted in other places...just giving you heads up on that.

As long as the lights are working on it, it shouldn't need replacing. We kept our last ones for years. Just replaced them for updated ones.

Don't know, I haven't had to replace them. But it's my understanding they last or thousands of hours.

I've only had mine for a month or so. However, I'm certain it depends on how often you use them and how well you take care of them after and between each use. I expect mine will last longer than 6 mo. as I don't wear them constantly.

Only when they crumble or break down. Otherwise you should not replace them.

I have only had mine two months, but they're holding up well so far. I think they'll make it 3 months plus. Hope this helps.

They are a very good replacement product for your device - my best guess is that each pair of pads has about 30 uses before they need to be replaced.

I don't see why you couldn't. However, since it is recommended to replace them every three months, I don't know why you would need to...
