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

Good product, great company

Filters are high quality. Water tastes very good and low TDS after installation. Installation takes time and more time if disinfecting the system, or changing all of the filters and ROC membrane. Getting under the sink while installing is tedious and back aching.

These filters are excellent. I was a bit skeptical until I started replacing each filter one by one as I noticed that water quality began to degrade after maybe about two months. Considering the quality of the average tap water, this is not a knock against these otherwise excellent made filters. Right after I began to change the filters, the water became noticeably cleaner again.

The unit says these are 10,000 gallon filters. This is about a 10-year supply for me. So far the first filters have lasted about 8,000 gallons without any issues.

It's good, exactly as advertised and expected. I saved so much money rather than calling the water company to switch it!
