Based on cost efficiency would I still need to replace the filter if there is no change in water taste despite 2 months or 200 gallons. If so, Why?

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.

We change the filter around every 4 months. I know when it is time to change the filter as the rate of flow of the water decreases as more material is filtered out of the water. I hope this helps you out. Good luck.

Possible concern is growth of pathogens on the filter media. We use ours for many months until volume is noticeably slower, indicating packing of media with filtrate.

I don't know anything about that. You are supposed to change the filters every two months.

The pre and post filter remove particles and they need to be replaced every six months. The RO Membrane (Reverse Osmosis) is a permeable membrane that lets pure water go through but not the bad stuff like arsenic, chlorine, etc. This cartridge is what makes the entire system work.We have well water and for my water I get about three years out of the RO Filter. My wife is the one with sensitive taste. When the water has no taste I know the RO is OK. When she tells me she can taste the water I know it's past time to change it.

Depends on whether you have soft water or not. I have soft water that runs through the filter. After one year the build up was almost nothing to be concerned with...........so I kept the original installed. But, I keep an eye on it monthly and replace it with a new filter that I bought via Amazon for $13.00 (just in case). On the other hand, a person I know has hard water and the filter has to be replaced yearly to include the automatic water shut off valve.

They have a recommended change schedule based on time and/or gallons, but you will be able to tell with the water taste. It also depends on the water quality within your area. I'm in Virginia Beach and the water quality is better than Florida, so my filter does last longer here. Flow rate can be deceiving since water pressure is not always the same. Amazon sells a water hardness tester, it could be helpful to better monitor your water quality!

That should be it. I have hard water and have to change my filter / wick every two months.

I haven't found it to improve the taste of the water but I've only had it for two months or so. We filter our water because our city water tastes pretty bad .

Hello Shelley, I often change the filters around 6 month and 1 year, this depends for the PH of water, I measure the PH if this drop down about 6, I change the filter.

Of course it is whichever comes earlier. But the one I have right now I have been using for four months and the water still tastes fine. I definitely have not used 40 gal through it yet.I do not know what the shelf life of the new filters is, but I think they are just carbon based so it should be a long time.

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.

It depends on how much water you're running through the filter. I live in an RV full-time and change my filter every other month.

Are you testing the water? I test every month to make sure I do not need to replace the filter.

[Sorry, I am having computer problems.] Re the filter. I guess it depends on the quality of your water. We are on a private well, and the water is very good. Our habit is to change the filters every 9 or 10 months. The plumber's rule of thumb at our house is to change things when the water starts to run slow - that could take a year. I'm too neurotic to wait that long! Lastly, there seems to be little water wasted in the process (maybe a small container's worth, about a quart). Best wishes, Lauren

The membrane need not be replaced at every filter change. Look in your owner's manual or look it up on the internet - most membranes last 2-3 years depending on use and the quality of the feed/inlet water supply. You only have to change the membrane when you notice a change in the quality of the water produced, or when the rate of water flow has diminished considerably.

I dont believe that that option was available when I purchased my filter, but mine works well; there is no taste, odor, or color in my water, and the 200 gallon size has only filtered 102 gallons since I started using it... it's lasting a long time

I did not notice any change in water flow or taste after 6 months. I have the subscription to automatically order it after 6 months...great filter!

We've had ours for about a year. No issues yet, just need to change the filter.
