Replacement Filter Set for Culligan AquaCleer AC-30 RO System — 4-Pack Cartridges & Membrane (Filters Only, No Housings)

First off, these fit the Culligan AC-30 and work with that system. Replacement is pretty simple, the issue for me is the tubing connectors on the unit, they always seem to leak after you move the unit around to get the filters out. I had no issues with the new filters fit. Took about 15 min to complete. Prior to install I did rinse the carbon filter for several minutes to flush out the dust. Don' know if it is necessary but I did rinse, or at least ran water through the others, prior to install just make sure there weren't any debris or manufacturing goop on them.

Easy replacement. Good price. TDS went from 283 with old filter/membrane to 91 within 4 hours and about 2 gallons of flush. 24 hours and about 4 gallons later TDS WAS 38. Water tastesMuch better as well. Membrane is about 1/2” short but fit firmly and should not impact performance.

Easy to install and works great. Water quality is great and tastes so clean. We have well water and our reverse osmosis system is the final step we use for filtered water and it helps SO much compared to our taps without R.O. Will definitely buy these filters again in 6 months. Well worth it.

Why didn't I know about these sooner? I was paying Culligan an arm and a leg to maintain my RO until I learned it was easy to replace these myself. The filters fit my Culligan system just like the originals and it's not too complicated to install. Just watch a few YouTube videos and you'll be off and running, The water flow great with these filters, tastes great, and tests show they are doing a great job of filtering the water. So glad I learned about these.

Contains all the four filters to renew the Culligan AquaCleer AC-30 Reverse Osmosis System. Easy to install and worked really well.

While these filters appear to be the same quality as the name brand filters, they simply do not filter well. I purchased a water test meter and tested my water after one year. It was still doing great at 7 ppm. I tested it again at two years and it was 12 ppm which is still good, but I decided to change to the new filters anyway. I then waited a week and tested the water. It was 67 ppm. I have tested a few times since and still get around 67 ppm. While it is an improvement from the 332 ppm that the incoming water tests at, it still is not in a range that is considered to be safe. The only posssible answer that I can come up with is that these are low quality filters.

Works great

Fit our Culligan AC-30 perfectly and is performing just like the OEM. Highly Recommend

works good

I have an older Culligan AC 30 aqua clear from. 2001. I called Culligan last week and they wanted 317 dollars plus HST for the same filters that I got on amazon for 69 bucks took 10 minutes to put together in the system. Culligan is insane. Perfect fit!!!!!

Great replacement for Calgon system

Excellent Product. Fits cartridges better than the original ones supplied with the unit. Order delivery was prompt and hassle free. Will buy again.

Be careful of ordering this item. It does not fit the Culligan water system. The filters we received from UrbanInspirations is completely unusable for us. It seems it is for a possible older AC-30 system where on can unscrew and replace the filters. Our AC-30 system is a newer system and there is no opening and replacing of the cartridge. The filter and outer housing are integrated together - so the entire cartridge has to be replaced. Make sure your system is not an integrated system before ordering. These AC-30 cartridges has one attachment point which is incompatible with our AC-30 Culligan system. Our AC-30 system requires cartridges with two attachment points. Had quite the run around before I was able to finally get a refund.
