About every 30 days but sometimes I let it go longer. Depends on it I am getting a good amount of insects.

I change mine every 90 days or so. I can usually tell when it is time by the taste of the coffee. We drink a lot of coffee.

In the Instructions it says when to change, I think once a year under normal use.

I just recently purchased the brush, so I haven't had to change it yet. They recommend changing it every three months.

You can change it as many times as you want. Just don't lose the little metal insert that comes with it. That is what you use to change to combination.

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 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.

I replace mine once a year. A lot depends on how clean your house is and if you have pets that shed hair. I have two cats.

It really depends on how many you have in your household using the shower. The more showers the more frequent changes. For my husband and myself, we change it about every 9 months or so. If you have a family using the shower frequently then maybe every 6 months.

I change when it gets too old, worn and tear. But I would rather change fliters every 6 months to a year. It depends. I have 4 cats and it gets to use a lot. So you know it depends on what your situation is.

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

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

We change it about every 2 months, we have small dogs so it doesn't need to be done ant oftener.

When the water flow is reduced, then it is time to change.For up to 4 people in a household, you can change 1x a year. If there are more than 4 people in the household then it is best to change it every 6 months.Feel free to ask any further questions.Looking forward to hearing from you.

I usually put in about 3/4 of an inch and I change it every two to three three days... every day in hot weather. Also, if I know I won't be using it for a couple of days I put it in the refrigerator.

There's not one answer to this question. It depends on the environment you live in and possibly the allergy sensitivities of people in the home. It's good to check them every month or so. We live inside a hardwood forest and it seems to me, we have to change ours about every 3 months or so. You can tell when they need changing, just by looking at them. If your environment has a lot of dust or other particles in it, you may need to change it every month. On the other hand, you might be able to go six months without changing it. Hope that helps some.
