Culligan AquaCleer AC-30 Reverse Osmosis System Compatible Replacement Cartridge, Filter, and Membrane - 4 Set

Excellent 👍

These filters work perfectly in my Culligan system. The polishing filter that goes directly before the spigot posed an interesting challenge as my old one used 1/4" line and this one takes 3/8" water line, but it was an easy enough fix with some 3/8" water line and 1/4" to 3/8" push connection adapters from the hardware store to splice this filter in (now I have the ability to easily use either a 1/4" or 3/8" filter with very little effort). I'm happy and when it comes time to change filters again, I'll likely purchase this same exact product again.

Perfect replacement.

Love the price works well easy to install if you have replaced them before

Here’s the rundown. 1) I am handy and have changed these filters before MANY times w OEM filters. Installation was simple and all filters fit just like OEM. 2) Membrane filter performs poorly. My 2 year old OEM membrane was filtering at 210 before I took it out and this replacement membrane filters at 240 brand new. 3) the other 3 filters are critical to the taste and do a lousy job. Nowhere near the clean taste that the Culligan OEM filters provide. I will try to return for a refund but not expecting to get very far.

I used these filter on my Culligan’s water drinking system. It removed all hardiness. The filters don’t look exacted but they work great. I’ve had them in for 3 months no problems and hardiness still gone.

Price was right and shipping was fast but I had an issue with the post-carbon filter leaking and greatly reduced water pressure at the Culligan tap. I did notice the membrane was a tad longer than the others but I'm not sure how or if it hinders proper function.

I have the Culligan AC30 clean water machine RO. I did some reviews and these came out pretty good so I went with it. The regular tap water TDS was 240. With the previous RO filters (that were 6 months old) I was at 50 TDS, after installing these, I was at 9 TDS. I did have to cut off the lower quarter inch on the reverse osmosis membrane, but that was easy- but kind of a pain. I would order these again. Except for having to cut off the bottom of the membrane to fit in, these went in perfectly and flushed out quickly. Very nice.They easily would have received five stars had I not have had to cut off the bottom of the membrane mount. It does seem and though it would just twist out with a pair of pliers; there was a clear break in the membrane mount for the additional length that I had to cut off. If they could make that so it could be pulled out with pliers (thereby allowing it to fit into multiple different brands of RO machines) instead of having to be cut out, these things would get 10 stars!
