435 R.O. Pre & Post Filters with Membrane Set for TFC-25D , TFC-4, TFC-435

Well packaged and correct fit for my filter system.

Very pleased with products quality!

I like that I can replace these myself as often as I need to.

The filters appear to be working as advertised. Only gave 4 stars because the little filter that goes to the dispenser was different than the one that was originally installed. The old one had threads. Then new one did not. Being plumbingly challenged, I had to get the Culligan Man to come and instal a reducer and show me how to replace it in the future. My advice, don't dig out the plastic on the ends looking for the threads.

Wepurpased our filtration system through one of our local companies. It was expensive and when it came time to change the filters I was relatively surprised at how cheap this pack was. I purchased the 4 stage system filters. My husband was able to replace them fairly easy. We never have done it before. We thought the water tasted just fine and didn't need ereplacing yet, but the filters that came with our installed system was only a 6 month them need to replace. We went 8 months before installing these filters. We couldn't be happier, these filters made all the difference in our water. The water tastes so good that it makes you thirst for more of that goodness

easy install... decent price

Bought the 4 pc kit to have oil the shelf for when needed. Visually compared these replacements to the originals, and they look like the right parts. Won't know for sure until they need to be replaced, which is the only bad aspect ... won't be able to return. But, all looks good / no shipping damage / no packing damage.

Quick Connect Inline GAC Water Filter pipe hole size is not big enough. Can you have a replacement?
