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

Fantastic! Ppm 13 yay

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

Good

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

Great!

Pretty good so far

The Express Water – 3 Year Reverse Osmosis System Replacement Filter is a must-have for anyone using their express water reverse osmosis system. While the recommended replacement frequency is every 6 months, I found that changing it once a year was sufficient for my needs. However, having these replacement filters readily available is essential to ensure the continuous and effective operation of the system. Its always better to be prepared and have the necessary replacements on hand, as it guarantees uninterrupted access to clean and purified water. With the Express Water Replacement Filter, you can maintain the performance of your reverse osmosis system and enjoy peace of mind knowing that youre always prepared for the next filter change. It doesnt come with the RO membrane so you will need to purchase that separately

I got what I needed

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.

They were exact replacement for the old ones
