What is the purpose of the RO Membrane? It's sold separately from the filters. Does this need to be replaced every time the filters are replaced?

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.

The RO membrane is the one that filters out the smallest of particles. You can change the RO membrane about every other time that you change the two filters or if you notice an increase in the amount of time it takes to refill the tank.

The r o is only replaced after 6 months to a year depending on water quality and usage. I changed ours after 3 years only because it seemed like a good idea. Never noticed any change

It is a finer membrane then the prefilter and yes it should be changed with other filters

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.

It depends on your water source and its quality,if you use this residentially or commercially,but I would get a TDS meter(cheap here) and this gives you an idea of incoming water vs your RO system has purified,you can google TDS values and get a idea of good and bad.In my situation my incoming water is around 160ppm and my RO system water is around 7 ppm.You need to do a quick and easy calculation(google it) of your situation,and this will tell you the performance of the membrane and its efficiency.I typically get at least 3 years to a membrane,but check mine often,with my TDS meter. I know this is long winded but every situation is different,it's really very simple once you get the TDS meter,thus being much more accurate,also the membranes are rated for efficiency,so make sure you get one that works for you. thanks,good luck

The replacement filters are tied on. With regular cleaning I've been using the same cloth filter for three months and going strong.

If it's like mine (and it looks like it is), this is compatible with MOST water filter systems, quite easily. That includes most RO (reverse osmosis) systems. I called the company before ordering and asked them, and would suggest you call this company too, to make sure.

The filter is two part--cloth inside with a plastic and mesh cover over that. You can wash the cloth filter and replace it. I purchased a couple replacements from Amazon so that I always have one to put on while the other is drying. They will get to a point where they have to be replaced but I have had my vacuum two years and only replaced the cloth filter once but that may be because I wash them often, hence the beauty of having a couple of extra filters hanging around.

RO is known to remove salts and minerals which make the taste bland. I prefer not having RO because of the amount of water waste it takes to generate the pure water and the water needs to be stored in holding tank because the pressure and amount of on-demand water from RO systems does not compare to the tap. Tap is perfectly safe by itself. Personally I just think RO is a bit overboard unless you have a good reason to use it (i.e.: ground water, wells, fracking, etc)

Only my first filter was appreciably off-white after a year.Keep in mind that their main purpose is to avoid contaminating the RO membrane.

As I know it a RO filtration system will remove 96% of all contaminates. You probably have no better choice. We have 2 one at work and one at home and these are used exclusively for drinking water and ice maker water. They have both worked great and once you see what just the prefilter removes you will be amazed. I would highly recommend and RO system even if you think you have good water. Our employees haul water home.

The filter is integrated into the cartridge. It is not separate. There are replacements available on Amazon and usually last 1 year of use.

I did not use the filters as we have a whole house system on our home as well and a reverse osmosis drinking water system. I only used the RO water in the fountian. My bulldog puppy has they unit chewed up with in a week :(

Actually, I have a revers osmosis system in my house for drinking water and I didn't use the filter. I was told by my plumber if I filtered my RO system it will slow down my water pressure. The RO water is already great and I didn't need another filter. If I did use it though it would be easy to change. I have an extra filter.

I don't know the answer to that, I just use the filters that came with it.Remember to clean them after each use.

No, there is no reason to, considering the kind and number of filters the water passes through, including the RO membrane.

NO now the system needs a new membrane once a year,but the other filters every 6 months,

According to Lotus, the purpose of the filter is to remove excess humidity in the air allowing the Lotus to infuse more ozone into the water. They recommend replacing the filter every 3 months based on average household usage of 4 people using it 2 times a day. I only use mine once a week (at most), so I figure that 1 use per day should be good for 45 days, therefore my use of once per week should be good for almost a year. (7x45=315 days), but that is just my opinion.

The filter is some kind of synthetic material--I think--very fine mesh. It eventually clogs, and you either have to take the basket apart to clean the filter or simply replace the whole basket. It's pricey, though, about 25.00, including shipping.

This is just a refill filter for the reusable filters. It goes right inside those. Can't use this without one.
