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.

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

The middle filter does not work in my standard housing. It lets littlw to no water get by and had me chasing my tail trying to figure out why I would loose all pressure. Will never buy this set again

Fantastic! Ppm 13 yay

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!

Good

Good bargain for replacements

Pretty good so far

Great
