The company says replace yearly, but is there a way to tell if they need changing sooner, like running with them?

I'm not a runner but I would suspect that if your PF starts to act up then the inserts need replacing. I would think that running would put more wear and tear on the inserts than walking so they would break down sooner.

It is recommended to replace both at once, but I didn't. I changed it 4 years ago and haven't had a single issue.

You can probably just get the company contact info front their website and have them send you a new one.

I am not sure. I have only recently started replacing ones at the business that I work at.

It had a "best if used by" date that was over a year out. You will probably have to contact the company to get any additional info beyond that.

I change mine all the time by hand - never had a problem. These have worked well for me.

I would think from the manufacturer. I haven't changed mine yet. It would depend on how much heavy use as far as when you have to change it.

and usage...if you run it 24/7. I would change every three or four months. Some folks just vacuum the filters. I'm goona try it.)

We just replaced our first one after 4 months. Will probably replace it every 3 to 4 months from now on.

according to use, we use ours often so we change bout every 2 months, but it no hassle. Listen when we are on vacation or a business trip, we look at each other and say "I will be so glad to get home to my bathroom". The best part of my $15,000 bathroom remodel. Dont hesitate BUY IT!

We are following the manufacturer's recommendation and are replacing it annually.

I've changed mine when needed, around 6-12 months, and it does make a difference.

That is a good question. We have been using ours for 5 years and haven't changed them so far.

Sure it is possible, but I can't imagine how much use you would have to have before you needed to change one.
