How often do these filters need to changed?

Every six months for two users. Well ....sensibles users. :-). If you frequently run out of hot water in long showers it will be six months for one user. :-)

I live in San Fernando Valley and have hard water so every 3 months for 2 people. When water pressure gets low its time to change

Our shower is used about 2-3 times daily. Our area has extremely hard water so our filters only last about 3-4 months. I change them when my skin starts to dry out (severe eczema,) or it smells heavily of chlorine.

We change ours every 3 months (90 days) - We have a thing set up with Amazon to send us a filter quarterly, we have an extra on hand so after I use the one I have a new one waiting. Ours has a dial on top to tell me when to change (in case I forget)

I've owned a unit about two years. I replaced the filter after year 1 and just replaced it the second time. The unit seemed to work OK, but the filter does get a little "grungy". I'd say replace at least once a year (I only run the unit during the winter and early Spring months-November to April)

The problem is that carbon filters provide a warm moist environment to grow bacteria so you pobably want to change them every 3 to 4 months. S.Chiples

Printed on the edge of the filter: "Change every 6 to 12 months - more often if the filter appears dirty." My HVAC person recommended every 6 months.

About 3 weeks. I smell them everytime I change the water. It is obvious when the smell changes, change the filter.

You change it every three months. I purchased this after looking at others without filters. Totally good value .

I have used these filters for the past 1 1/2 years without any problems. Sorry you encountered a problem.

Depends on use. I replace mine every 6 months. But I also keep my hot tub very clean and wash filter every month.

I would say it depends on the conditions at your home. We live up in the mountains where it is very dusty, so we check it at least once a month. We'll change it based on the amount of dust on the filter paper. We can generally go a couple of months before having to change it out.

Generally, you should change your 1/2", 1" and 2" air filters every 30, 60, or 90 days; the 4", 5" and 6" air filters should be changed every 3 to 6 months, depending on your environment. Thanks, Jessica

I change all the filters once per year with the exception of the membrane. That one is good for three years.

Depends on how often you run the machine...I run mine about 12 hours per day and I change the filters about every 18 months.

Hi . I usually change the filter ones a month when you do the water changes but don't do it together first hoy can change the filter and wait about a week and then do the water change

The filters are typically replaced annually. The membrane should be replaced every 3-5 years. These figures are for typical municipal water conditions. Part# B000F5M6V6

I would think changing it would not be an issue for quite a while. I only use it once per month. The current filter should stay good for a long time at that usage rate. When the time comes, I will rinse the filter and put back in for as long as I can.

Membrane every 2 years. Filters need to be changed more often--according to the amount of use.
