How does this filtration differ from reverse osmosis filtration?

Berkey is a physical gravity fed filter that sits on the counter top and reverse osmosis is also a filtering system but needs a tank under the sink. RO is a filter that is utilizes pressure to push water thru the filters that takes out smaller and smaller particles. Reverse osmosis probably removes more contaminants than the ceramic filters but may be comparable to the black berkey filters. Neither take out fluoride from what I have read but I don't know that for sure. Berkey does have extra arsenic/fluoride filters that you can use in conjunction with the ceramic or black filters that supposedly removes fluoride. I believe reverse osmosis might need electricity but not sure. Also Berkey is portable. Reverse osmosis is not.

apparently there is a waste of water for reverse osmosis. not for the berkey system. see their website

I use mine in reverse osmosis water (not salt water) & the filter works good.

My suggestion would be to install the eSpring filter after the RO one. You see, the RO systems remove the larger-sized particles (look up Reverse osmosis' in Wikipedia for more details). The eSpring would then come in to take care of the smaller particles and wouldn't be clogged with the big ones.

Carbon filters do not remove fluoride, that is correct. Reverse osmosis will remove fluoride and special fluoride removing filters will also remove it. We have a 3 stage and a 2 stage big blue system that use fluoride removal activated alumina filters. They remove fluoride from 70-94% depending on your levels and flow rates.

Dear Kimberly, I am not the manufacturer, only a very happy consumer. I have no idea... I actually had no idea ANY reverse osmosis system could represent many gallons of waste water, if this is what you are implying. Should that be the case, then I would immediately revert to drinking mineral water out of those wonderful plastic bottles sold by Dasani, etc...

The unit will work without a filter and does not have one. I have connected my reverse osmosis system to the dispenser. It works great. If a reverse osmosis system is not available, an in line carbon filter will do just fine for drinking water. This filter can be very inexpensive. I will be glad to help if you have any other questions. FPROPLUMBING@GMAIL.COM

Well I had the reverse osmosis water filter system for years and I decided to try out the waterchef u9000. Well the taste of water is definitely different between the 2. I prefer the reverse osmosis taste, this is in addition to a whole house water filtration system, since we live in an area where they use well water/hard water.

Unknown concerning similarities. However - I DO know that purchase of this filter or a substitute is an absolute waste of money. The filter does nothing. Period. It's only purpose is to flop around in the container when one adds water. Don't waste your money!

Do not know but I thought I noticed a difference when I used tap water rather than filtered ice water from the fridge. The tap water was better. I must compare with bottled water.

Sort of. The meter measures total dissolved solids, whether it is calcium or sodium or potassium it does not distinguish. Hard water is hard because the calcium is dissolved in the water, therefore if you take a reading with a hard water sample, you'll get back a reading with a high number as compared to a sample from a properly working reverse osmosis system or a sample of distilled water. Likewise if you take a reading from a soft water sample you will also get a reading with a high number as the calcium has been replaced with sodium (or potassium) in softened water. The meter is primarily to confirm that your reverse osmosis system is properly working and when the membrane filter needs to be 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.

Simply distilled or reverse-osmosis water is fine - BUT make sure you still check the bottle to make sure it is not fortified with any additional minerals.

I already had one from a previous reverse osmosis filter. So quite frankly, I don't remember now if it came with one, but I don't think so.

I think it doesn't. My filtration system has the reverse osmosis system embedded in the system so it doesn't need it. I've had this faucet for a long time now and it is excellent. Just in case. Hope this helps!!!!

Yes it will work with reverse osmosis. Only we had to buy a connector to convert to a narrower tube.

reverse osmosis units ' dispose' a certain number of gallons of water, and filter out the clean treated water. for every gallon of clean treated water you get, it would have disposed 2 gallons.
