Watts Premier Bi-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

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

They’re exact replacements and installed easier than any other filtration system I’ve used. They come with a plastic cap under vacuum I believe, not nitrogen filled and again sealed in it’s individual clear plastic shrink sealed wrapper and then placed side by side and sealed again as a single package. Then placed and shipped in a perfect size Amazon box. In my opinion very clean and safe.

I use these filters for under counter water filtration for drinking. Long-lasting and easy to change filters.

It was very easy to replace the old filters and install the new ones.

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

I like that this kit has everything required for annual filter change outs. They are a breeze to change and convenient.

Works great and easy to install! Don't forget to flush your tank after installing new cartridges.

Всичко е добре!

God quality, perfect fit. The set will provide one year supply

As always, quality, packaging and delivery are excellent.

Don't need a picture. Pictured as is. Best filters I've ever used. I've been using them for 15 years. I mean over 15 years. I replace them as recommended before. But after so many years of experience and to reduce waste, I now replace them when the water production stops. That usually means filter is clogged.

Being able to purchase it in a kit is helpful. Used in Maintenance of Reverse Osmosis Water System.

They are great and very good water.
