How often do you need to change it, once a year? Does it actually use reverse osmosis? Thanks

15,000 gallons, or every 16 months, depends really , how much water do you drink a year?

Hi, I have not changed mine as of yet. It says the membrane can last up to 3-5 yrs, I have had mine since Oct. 2012. Works great, I love it, does what I need it for. I use it for my Reef tank. I hope I helped a little. If I were you I would go to their web site to make sure. Thanks for asking! Linda

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.

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 backwash the filter once a month during swimming season and a little less often other times. Pull filter out and hose off about twice a year. Not too bad.

Trust me, change it every 30 days if you want the water to be fresh. If you forget to change it for 3 months, it will smell funny and won't be filtering properly. If you have ever noticed a water bowl getting a little slippery inside, think of what a filter after 90 days in water would be like. I got rid of my fresh flow because there were too many crevices that I couldn't get clean enough and it wasn't as fresh as changing out the water in a bowl everyday.

I find that changing that filter every 12 to 18 mos. is plenty to keep the water clean and fresh. As others have said, the company says annually, but they are making money more often that way. The filter I bought here is exactly the same except it has a lower price. What is not to love about that? (put masking tape on your filter and put the date your new one should be installed right on the filter casing.)

YES! We used our first one for almost a year before switching to a new one! We only used filtered water and clean it every couple months. Of course you clean the filters every time you use it.

My understanding is once a year. From what I understand, the company will send out a notification each year. We installed our unit 10 months ago and have the water tested monthly......ten months and no problems.

We only change ours out once a month. The water remains clean for that duration.

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

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

I have used this filter the same way for about a year now. Single person use, drink a gallon daily, use it for cooking. I replace every 5 months.

I change mine on average every 4-6 weeks. We have moderately hard water and it gets progressively crustier at the top as time goes by; this reduces its efficiency in humidifying the air. You will know this is happening if it uses less and less water even on the high fan setting.

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.

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 replace this specific membrane about 2 years. The others 3 stages (big ones) have to replace twice and one of this stage - important that how many people in a home using water thru this system and quality of local water: the more people the shorter replacement. Good luck.

I think they officially want you to replace them every 6 months but I usually replace them around once a year. It depends on your usage. I have it hooked up to a below counter ice maker & also a drinking water dispenser above counter. When the water starts running slow on the dispenser I replace the filter.
