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

This is my 3rd Express Water Filter Replacement Set. I cant really tell if the filters are the best filters, all I can say is they worked as designed; my clean water would not go lower than 34(tds), but it could be the water source is not good. Overall, these filters are ok.

The pack originally came with 3 filters that did not fit the connections on my system. After contacting Express Water, they made every attempt to make it right. And they did. Best customer service I have worked with. The filters are installed and working properly.

Pretty good so far

Cost and connection ease

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

Good products

it is very good abd delivery fast, but, could you help me to find the connector,1/4 3-way Union Tee Tube Quick Connect Push Fit RO Water Reverse Osmosis Excellent and 2-way connector, my old connector is differnent type, and another, the reverse member tube cap is too tightly, i can nog open it, how can i do?

Great!

They were exact replacement for the old ones

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
