Is this membrane supposed to be changed every 6 months, 2 years, or 5 years? I read 6 months, 2 years and 5 years in the description

The only other reason to change more frequently is if microbial contamination is a concern, I put a UV light treatment unit following my RO system to help fix any problems encountered here. Now I have a UV light to change once per year and another filter to change once every 6 months in addition to RO filters and membrane service intervals.

I'm not certain but I think 2 years based on the first time I changed it. Unrelated to your question the instructions told me to run water through it for 2 hours before using it due to some preservative that the membrane is coated in. Paranoid at the instructions and since I could not run water other than at a trickle for that long... I waited a couple of days before drinking from it, alternating running water for 5-10 minutes several times with the tap completely open, then recharging and also letting it trickle overnight.

I change the membrane once a year and the filters every six months. Works well for me.

Two years is the nominal service interval for these. The best way to monitor the performance of these is to use an inexpensive TDS meter to ensure the membrane is removing greater than 85% of the total dissolved solids from your water. Depending on the water you are treating and prefiltration in your system and water pressure you may be able to get 5 years out of your membrane, or less than two. Get the TDS meter, you will have fun monitoring the performance of your system!

We replace ours about every 2-3 years. Our son works for a water improvement company and he told us every 2 years. Hope this helps

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

The water may taste different, or smell different. Best to change every 2 months

I'm not sure what the recommendations are for changing this filter, but when we notice that our water is tasting funny, we change the filter (about every 12 months). There are probably a lot of variables at play, such as the minerals in your water, chemicals, etc.

Usually every 6 months or so depending on usage. The machine will tell you when the filter needs changing

We recommend changing the filter every 6 to 8 months. However, the filter life will depend upon the environment in which it is used.

I believe it is 5 years. I would check the manufacturers website to be sure.

It's a certain amount of gallons, but obviously no one is keeping track of that. I think the rule of thumb is every six months depending on usage (although with smaller families or couples maybe a year) but for me I just look at the filter. It will start a light color and very gradually begin to darken. I change mine when it gets completely dark, which is always around the six month mark.

I change this filter every 6 months..but I only put on about 5000-6000 miles every 6 months.These are nice filters for the money!

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

Even though the specs somewhere says every 6 months, I have vacuumed the internal ones and washed the foam one. the foam one is the one that gets the coarse dust, taking into account that the filter is in a "clean" room. I have seen an improvement in our quality of sleep since we got this filter ( use to have an ionizer one)

The filters last more long than, but i personally change it every time I notice the water pressure of the filtered water decreases which usually happens after 5-6 months but it also depends on how much water you drink a day

The directions for the platinum model say the filter should be changed every two to four weeks. It also says you can thoroughly rinse the filter and put it back in. I've had no problems with doing that.

Directions say one filter is rel\placed at 6 months and second is replaced at one year. Sorry, I do not remember which gets replaced at which time frame.

The instructions state the filter should need to be changed every 6 Months. I bought mine in December 2012 and have not changed the filter yet. The unit has four lights that indicate when the filter needs to be changed. Mine is only on the second light indicator. I run the unit 24/7 on the second of four speeds, and wash the foam pre-filter every month.

Using this water treatment your water storage is good for 5 years...no need to change out every 6 months.

I change them a little longer that the recommended times. We use the filtered water only for cooking and related things. There are two time frames: One filter will last one year plus and the other two should be changed every 6 months. As I said we try to wait a little longer. Maybe 8 months for the two and 14- to 16 months on the one. It really depends on use and the quality of your water.

I think that's the membrane I use for mine. Keep in mind that's the membrane, so it doesn't need replaced as often as the filters.
