Reverse osmosis (RO) has become a common home water treatment method for drinking water that might be contaminated.
The method of purifying water by reverse osmosis is used by many people these days, to simply purify their water and remove salts and impurities which would result in improving the taste and odor of the fluid. Reverse Osmosis rejects bacteria, proteins, sugars, particles, and dyes that have a molecular weight of more than 150 to 250 Dalton.

I have a Culligan AC-30 with 3/8″ and some 1/4″ Guest fittings.
Is the OmniPure K2333KK the right post carbon filter?
How does the RO membrane compare to the one they used in area, filtering ability, etc.
Culligan reverse osmosis systems all use the same activated carbon prefilter, activated carbon post filter, and particulate filter. However the reverse osmosis module/membrane varies between the units, and the Post Filters come with different connection settings. In most cases, the membrane is from same manufacturer, with different label.

I have a GE smartwater gxrv10abl01 water filtering system. I see the 155268
CBR2-10 listed as a replacment filter, but only as the POST filter, not the PRE filter. Why?
GE states that it’s filter, the fxp12 is used as BOTH the pre and post filters.
Can I use this 155268 CBR2-10 as BOTH filters??
Is there any (dis)advantages???
Why are these filters so much CHEAPER than the OEM filters?
Do they meet the same spec’s???
I’m willing to buy them, but such a huge diffrence is price makes me nervous.
Last, will these “bolt right in”?????
I’m a techie type and don’t want parts that I need to “adapet”.
GE FX12P replacements would be the CBR2-10 too, but although you can use the CBR2-10 as a pre-filter, it’s more expensive.
These replacement filters will fit in correctly.
Same or better technology then the OEM.
In fact GE is not the manufacturer of these units, and I’m most certain they use the same brand with a different label.

If you home drinking water comes from a municipal or city water system, then the tap water you drink comes through a real maze of filtration procedures before it reaches your faucet. The water enters into the main water system without any purification at all, from where it’s passed through a filtration process of sand, synthetic floss, fine gravel, or all 3 combined.
This filtration process removes sediment particles, and some cloudiness. Further down the pipe, Granular Activated Carbon take harmful toxins out of the purified water, in a system procedure known as chemical filtration. The final filtration stage is biological water filtration. Some water treatment plants also have their purified water go through plant life, to remove (absorb) nitrates and other nitrogen from the water.
A similar filtration process may be seen in home aquariums.

I purchased a home with a Water Factory SQC-3 Reverse Osmosis Drinking Water System installed under the kitchen sink.
It seems to work fine, except for a water leak once I removed one of the cartridge filters trying to figure it out.
The system usese one High flux TFC membrane, and water factory replacement filter parts #47-55706G2 (pre sediment/carbon split), #47-55710G2 (post carbon block filter), #66-4703G2 (Reverse Osmosis membrane).
There wasn’t any paperwork on how to maintain the system, can you supply me with instructions on how to preform proper maintenance?
Thanks for contacting us.
We currently don’t provide local service. Sorry.
You may wish to contact the manufacturer for assistance in resolving this matter.

We have a reverse osmosis system under our kitchen sink.
It is called “Culligan Cleer.”
There are three filters.
The model numbers are:
- AC-15
- AC-15M
- AC-15L
Do you have something to replace these Culligan filters?
We would like to replace them ourselves, and thought it would be more economical to buy them online rather than through the Culligan Dealer, or is it so?
Thank you.
When purchasing in bulk, it’s more economical to buy the Culligan Reverse Osmosis filters online. If you need personalized service, your Culligan Man would be the better approach.
Culligan water filtration products reduce the presence of sediment and bad taste and odor.
Some Water Purification products remove or at least reduce the presence of contaminants such as nitrates, mercury, herbicides, pesticides, lead, giardia, cryptosporidium, and asbestos. Please note that not all bad things in the water that can be remove, are actually there before installing the water treatment device. It’s up to you to do a Water Test before spending a fortune on something not needed.
To sum it all up, if you are not sure what is wrong with your water, you may want to try a water test kit. The test kits will tell you which, if any, contaminants are in your water.

A post from long ago, Reverse Osmosis Article June 05, comments a little about Reverse Osmosis for Car Wash.
Recently, some readers suggest we add the following lines to complete the thread.
When car washes were first introduced they used three things: soap to clean the car, water to rinse it off and towels to dry it.

I have recently ordered replacement filters for my Microline T.F.C. 25S RO water filter, and still am receiving a VERY small amount of water….
Can my current tank (which is what I now suspect is the problem), be recharged, and how would I do this?
Or do I need to replace the tank?
Is the RO4B tank compatible with my MicroLine RO system?
The tank and RO system are currently under my kitchen sink.
Is it better idea to get a tank (if I need to replace it) with the replaceable bladder?
Thank you for your assistance with these questions.
Here’s the information that might be helpful.
RECHARGING STORAGE TANK PROCEDURE
PROBLEMS:
When you turn on the RO spigot you noticed small water pressure coming from the storage tank.
When you turn on the RO spigot, only a quick burst of pure water comes out of the system, and it slowly dies down to trickles.
When you turn on the Reverse Osmosis spigot in the morning, you only can get less than one gallon of purified water.

I have one up question.Why does the RO water “dissolve” the copper piping?I thought that RO water was really “only” ultra filtered water (i.e. water that has passed through a permeable film leaving behind undesirables) and as such the chemical composition should not have changed.
I can only wonder what it would do to your stomach if it “dissolves” copper!
Thanks for your comprehensive reply.
From Cornell University site (PDF file is here):
The storage tank, tubing, and dispensing faucet should be made of plastic, stainless steel, or other nontoxic materials. The low pH and mineral content of RO-treated water may corrode copper pipes and allow lead to leach into the drinking water from brass components.

I want to install an under counter type filter in my basement and pipe the purified water to a sink mounted spigot and my ice maker.
I understand that the RO unit produces waste water.
Do I have to have access to a drain to dispose of this water?
As you’ve indicated, there needs to be access to a drain for the rejected water. Also keep in mind, that the water pressure needs to be high enough, to provide purified water at a satisfactory rate. If it’s low, a booster pump might help.
Hope you succeed.

I would like to know if both the Reverse Osmosis and the Distilled Water Systems remove salt from the treated water.Has a test been conducted that I might see the results of water before treatment and after treatment?thanks.
The answer is Yes.
Both technologies, Reverse Osmosis and/or Water Distillation would remove the salt.

OVERVIEW
We have a new home under construction in the remote mountains of Colorado.
In our new home, our water source will be a well and our sewage will go into a septic system. Our current home has a reverse osmosis unit so we have some knowledge of those devices.
On Wednesday of this coming week the drywall contractor will start closing the walls and ceilings. We will probably want reverse osmosis drinking water to be available at the Kitchen sink and at both sinks in the Master Bath. The Kitchen is directly above the Mechanical Room. The Master Bath is above a storage room.

i have an under the cabinet culligan aqua-clear three stage system.
the serial number on the back is ac 10057618 and it shows ac30 premium, ac30m, and ac30l.
i believe its two filters and a reverse osmosis cartridge.
What are the replacements needed for this one?
The Culligan Aqua Clear RO filters all use the same granular activated carbon pre-filter, the same activated carbon post filter, and the same particulate filter.
However the reverse osmosis module/membrane varies between the units.
Also, the size of the post filter is different.

Here’s some information on how to change the Reverse Osmosis membrane for a standard RO water purification unit
Changing RO Membrane
Turn off the valve where water comes into the RO unit.
Turn off the ball valve from the storage tank.
Open the faucet of the Reverse Osmosis unit, to free pressue from the system.
Disconnect the tube that connects to the end of the membrane housing - on the end that has only one tube going into it.
Unscrew and open the cap of the membrane housing. Water will come pouring out.
Pull out and discard the old membrane.
If necessary, clean membrane housing with warm soapy water.
Insert the new membrane. Follow the direction of the arrow that’s usually on the membrane. The end with the small rings goes in first. The end with the large rubber ring (brine seal) would go in last, and face the outside of the housing. Push firmly!
Put the cap back on and reconnect the tube to the membrane housing.
Open the tank valve and the water inlet valve.
Drain the tank.
Refill and drain 3 times. That means: allow 3 full tanks to fill and drain. This shall flush the preservative from the membrane prior to drinking.

When I put in (replace) the 15 gallon per day Reverse Osmosis membrane, I lose water pressure to almost a drip.
Is this normal?
It’s possibly one of the following three issues:
REVERSE OSMOSIS UNIT Makes water slow.
o Normal R.O. process.
- Your 15 gpd Reverse Osmosis water purification system makes water a drop at a time. 3 gallons storage tank should be full in 6 – 10 hours.
o Low water pressure.
- Increase to 50 psi. Check for kinked tubes.
o Filters clogged.
- Replace filters.
o Membrane not installed correctly.
- Ensure installation is correct.

Chloramine is a combination of chlorine and ammonia.
To filter and get rid of chloramine, an extensive carbon block water filter (to reduce/remove chlorine part of the chloramine molecule) followed by a RO Reverse Osmosis or cation exchange filter (to remove the ammonia) is needed.
