Express Water – 3 Year Reverse Osmosis System Replacement Filter Set – 21 Filters, Carbon GAC, ACB, PAC Filters, Sediment SED Filters – 10 inch Size Water Filters

I got what I needed

Great price. The blue top carbon filter (2nd stage) top hole was too small for my system though. I have a standard 5 stage i-spring system, and the standard housing bits seem to take a ~1 1/16 filter hole. The hole in the blue housing was only abut 15/16. I had to drill it out with a forstener bit, and then it fit fine.

Very satisfied with this item. It is well packaged and appears to be good quality and I dont have to buy them again for a long time.

I bought this to replace my Costco reverse osmosis machine. Installing it was easy. Replacing the filters not as easy as my last one as the filter enclosure needs to be unscrewed rather than the quick disconnects of my old machine

Got our tds back down to 0 on our ro/di unit for our reef tank ( along with resin refill) great value!

everything arrived timely and packaged good ,each filter is individually wrapped, wouldve given 5 stars but the post carbon filter will not fit my system, as I actually have 2 lines running into the post carbon filter ,I actually need the screw in type post carbon filter ,oh well live and learn, that makes 6 post carbon filters I have and no way to use them that I know of, now I need to go and buy the correct post carbon filter, even without being able to use the post carbon filters it was still a good deal

Perfect I now have a supply of filters so I can replace them when needed.
