Instructions say change every 6 months. Shouldn't the change rate be in gallons of water used? Family of 2 as opposed to family of 6....

The 6 months is an estimate. The specs inform the cartridge should be replaced after 300 gallons.

It's been 4 months and my water filter still seems to be working great (2 person household.) Would be great if someone could post a link to a consumer reports type article about this subject. Of course the mnfctr is going to recommend faster changes than are necessary to get you to buy more. I just set up 3 month regular shipment from Amazon, to be safe.

I change mine every 6 to 9 months. It greatly depends on how wet the conditions are, and how good the inside filter does. All depends on how bad the system enviroment is.

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)

The recommendation is to change it monthly. Just make sure you don't get it wet.

When the filter needs to be changed, the water flow slows down. It all depends on how many contaminants are in your water. My water is pretty clean, so I only have to replace the filter every 6 months.

Well we have been using these for YEARS, and probably don't use a gallon a week. I will refill our tea kettle a couple or three times per week, so I doubt we use 200 gals per year, so I have changed them only once yearly, like around NOW, and have never had a problem or gotten ill. I always do run it for a good THREE count, as the manual says though.

I'm checking my water bill usage and going by 44,000 gallons. They don't indicate the amount of people in the household for assuming 6 months.

Hi Bob: This totally depends on the quality of water in your area. If you are using frequently as you seem to, I would tend to be conservative and maybe change every 4 months. I change mine every six months or so but I use it along with spring water for actually drinking. My husband uses it for drinking and I use it for all cooking. It has definitely cut back on how much spring water we buy.

Even though it says every 6 months, we don't use it that often so what we do is change the the red and blue filters every 12 months and the purple filter every 24 months (yes 2 years). So far it has not degraded our water quality nor taste. I wouldn't push it more than that though. If you really want to be safe stick with what the manufacturer recommends, every 6 months for the red and blue filters and every year for the purple.

We change our filter out monthly. It gets used a lot as well. We are a family of 6.

I think it's once a month. We have softer water here in Hawaii so I change it every other month.

I have been cleaning the equipment each time the water starts tasting different. I change filters according to time, but if for some reason, the water continues to take differently, then I would replace it earlier. There isn't any type of indicator on the equipment, just your own site, taste, and time.

There is not meter or anything like that. Manufacturer recommends changing every 6 months. If it gets overused or you have a lot of TDS or minerals in your water it will slow the flow down when capacity is getting used up.

The replacement period is primarily determined by usage and the number of gallons if water filtered. I would monitor your usage and change it as needed. Its just my wife and I and we used it for cooking and drinking and got a couple years out of ours.
