CFSReplacement Water Filter Set Includes Carbon Block, Sediment & Inline Cartridges Compatible with AC-30 Reverse Osmosis System Models – Removes Bad Taste & Odor (Filter Set with Membrane)

There were no instructions to install this filter system so I called Culligan to install them for me. Culligan performed their normal install of the filters and left. I found out later that the RO filter is not pre-flushed like the OEM version and Culligan did not pre-flush it (which is not part of their normal install). I've had them in for 4 months now so the system should have flushed itself by now. But she water still does not taste very good at all. Also my water pressure out of Culligan's spigot is half of what it used to be as I can only fill about 2 quarts of water in a pitcher before it starts to reduce to nearly a trickle. Not sure why but they don't work nearly as well as the OEM version. Great price though.

these filters don't work in the AC-30 the RO filter is too long and the filters in general fall apart when you try to use the other two long white ones. The finishing filter does not sit in the Culligan bracket and on the whole this was so disappointing to learn AFTER I had cleaned the whole system out and tried to install the new ones. A complete waste of my time and money. Want the right ones, get them elsewhere, don't buy from this seller nor the similar ones fulfilled by Amazon itself, total scam.

You will need the manual for the reverse osmosis system in order to know how the filters should be installed. No instructions come with the filters. You can probably get a current manual on the system's manufacturer's website, but the directions may be a little different than those in the manual that came with the system. Just follow the instructions and you can do it.

WOULD HAVE BEEN A GREAT VALUE IF THE FILTERS ACTUALLY FIT. THE MEMBRANE FILTER DID NOT WORK. AFTER INSTALLING THE FILTERS, COULD NOT GET ANY FLOW AT THE TAP. HAD TO GET THE OLD MEMBRANE FILTER OUT OF THE GARBAGE, WASH IT OFF AND PUT IT BACK IN TO GET THE SYSTEM WORKING. THE SMALL INLINE FILTER LEAKS. PUT THE OLD ONE BACK ON TO STOP THE LEAK. I GUESS THATS WHY THE CULLIGAN FILTERS COST $175.

I have a Culligan Reverse Osmosis water system with an AC-30 Filters System.I have been paying over a $120,00 for replacement filters through Culligan water. I came across this AC-30 replacement filter for a fraction of the price of Culligan Water. This product was easy to install and works great.

The R.O. Module tip that goes in the bottom of the R.O. canister is about a quarter inch too long to work on older Culligan AC30 filtration systems.

Best product ever I really love it water's clean taste wonderful and I will always buy from Amazon again best prices , can't go wrong!

Installed easily on older ac-30 when installing middle filter insert into the tube first is a tip i got from a YouTube video I saw. After filters are let the water run and ensure that pressure is at 10 psi at tank.Turn off tap check pressure again and i had good water pressure and clean water
