How long does a water filter last?

I have a three filter set-up which lasts for a good 9 months of actual usage by two people over a 2+ yer period. Changed them because we started to notice a little bit of slow-down in the water flow and they were starting to let some calcium through that was starting to spot on the dishes.

I change mine every year. A season usually defines a specific period within a year. For most of us campers, we put the RV away for the winter meaning that our camping season begins in the spring and ends in the fall.

Shurflo says up to 2500 gallons on some filters but, how do that know what kind of water you have. If the flow slows down, replace it.

Thank you for the replies. We are spending 6 months in our RV with continuous use of the filter. So far we have been in the RV for 2 months, I am thinking after 3 months we should change the filter.

We typically change our yearly, however this year we had low flow in the shower all of a sudden on one trip, and found the filter to be totally clogged. It didn't make it through our camping season and we did have to change it. Hard water attacked it big time!

I know on mine it says to change every three months. That is based on 24/7 usage though. I change ours out once a year and it seems fine.

The cartridges I buy say 10,000 gallons but it also depends on water quality.
I pulled into ta private CG one time and found the previous tenant had left me a used water filter laying on the picnic table along with a clear plastic cup full of water. They were both extremely rusty and the water was cloudy.
I thought that was a nice thing to do for a stranger.
We used out own water.

My filter is only connected in line to a specific faucet on the sink. The rest of the system is just what's in the tank or city water connection.

I've changed it once in 14 years... ;)

Guess I'm about due now, since it's been about 7 years just to say I did it.. :)

Really, the only time we use that faucet is for the morning coffee, so we probably put a gallon or two thru it on a long weekend trip about 5-6 times a year..

Anyway, haven't gotten sick, or died yet! :) We always use our own water tank for water from home anyway, so no real worries... It's only a 30 gallon tank, so no big deal hauling it.

Good luck!

Depends where you travel and what the water quality is like. I generally check mine every 6 months, BUT if I am in an area where I don't trust the water or I know it is high in iron (for example) it will need changing early. If in doubt carry spares and check when you want to. It only takes s short time.

We are full-time and on average change ours about every 3 months. We are usually on city water, but you will find that even city water varies as some areas have a lot of lime in the water. We have had a couple of times after using well water (at a forestry park) that there was a funny smell to the water and our shower and toilet flow was low. Checked the filter and there was "slime" in it. We got the bleach out and used it to purify our water system, the filter housing, the inside of our white water hose, the tank and all water lines. So - if you notice a smell or low pressure, check the filter.
