Watts PremierBi-Annual RO Pure Plus 2-Pack Filtration Kit for 4 Stage Pure Plus/Zero Pure Plus Reverse Osmosis System, Push Button Water Filter Replacement, Sediment Filter, Carbon Pre-Filter

I love that filter.No more plastic bottles

Easy to install, no leaks, with great tasting water. I am glad we purchased this filtration system when Costco carried it!

A water main break near our house required the crew to open up the main line. A few days later, our sediment filter clogged up. Must have gotten some sand in the line. I'm so happy that the filter change only takes 10 seconds! Super easy maintenance on the Watts Premier RO Pure system!

Considerably more expensive than from manufacturer. Free shipping.

Installed easily into the system. Once flushed my water tastes just fine. These are the exact replacement units for my system so I did not expect any problems.After installation you have to flush the storage tank three times. It takes two to three hours to refill my storage tank so the process is tedious, be patient and read the directions! I suggest filling a container with filtered water before you start, that way there is some on hand.My directions suggested taking this time to check the pressure in the storage tank. For my system it should be 5 to 7 PSI in the tank. The pressure was low so I "carefully" pumped it up at the end of a drain cycle. It will push any remaining water out of the tank so you may have to pressurize several times. The tank MUST be empty for the final pressurization. I have much better flow now that I did that.One other thing, if your system is hooked up to your ice maker, isolate the ice maker before flushing the tanks 3 times. If you don't do this then you will need to flush the line going to the icemaker.The reason for knocking off one star is the price. I feel that the price could be a little more reasonable.

If your system has low pressure go ahead and just replace these two. Then see what happens. It was most likely one of these that was clogged

Ummm.. I don’t know what they want for a review. They are Watts premier five stage Reverse osmosis system filters. I love our reverse osmosis system and have had this for about 10 years now. These filters are very easy to change. They are no longer available for purchase easily in stores so that has led me to Amazon. This is the regular fair price. Not really a specifically Great price but the convenience of them showing up at my front door is awesome.

From the system to this filter set, it is second to none. I am like on my 5th system through the years.
