Watts Premier RO 4-Pack Filter Kit for 4 Stage Pure Plus/Zero Plus Reverse Osmosis System, Push Button Water Filter Replacement, Sediment, Carbon Pre- & Post, and Membrane Variants Included

Good fit for RoPure, easy installation.

Quality products but, description is needed for better results, also blowing up the picture did not help. I did find the right ones but it took a lot of work.

Fit perfectly. Very easy to install. Just push button above old filter to pull off. Then snap new one on.

I bought this set for my water purifier. It works great .

We had this water filtration system already installed when we bought our new home which gets well water. We didn't know when each filter was changed last so we decided to just start fresh and replaced all of the filters in the system at once. The water tastes great, just as good or better than bottled water. For a new homeowner this is a deal if you don't know when the filter was last changed. It's way more expensive to buy these one at a time and it wasn't worth the trouble to figure out which filter needed changing by trial and error so getting them all made the most sense. In the future it's slightly less expensive to get your 6-month, 1-year, and 5 year filters separately.

Prime shipping is paramount. I have two WATTS R O systems and these are perfect fit, take 10 minutes to install.

This filter has been in us at our house since 2008. Its great. This 4 cartridge package allows me to change them all.

Easy to replace. While Watts would like you to replace a set of filters once every few months (most of their RO systems include a flow meter that turns from green to red when you "need to replace" the filters), this part of their marketing is a scam. RO filter sets only need to be replaced when the total dissolved solids - TDS - number suddenly spikes, indicating a seal or a filter has failed. TDS should be tested once every few months, and the light turning from green to red is a great reminder to test. Removing the battery for the flow meter for a few seconds and replacing it resets the flow meter. I've had a Watts system for seven years and only recently has the TDS spiked, which provided me the information I needed to know it was now time to replace the filters. It's good work if you can get it, to have your customers dutifully replace an $80-100 set of filters once every 4-6 months when they see the light go from green to red. However, I think it is a much better investment to purchase and regularly use a digital TDS meter (it only takes a few seconds to test) for $50 to $100 and potentially save yourself $1700 of replacement filters. Please note, I've been building from scratch and maintaining retail RO systems for 40 years. Watts makes a good, inexpensive system. But I think they rely on back-end filter sales, like the razor / razor blade replacement business model.

Well packaged easy to install and do the job as I test our water.

Son filtros de agua. Es un kit muy completo, pues incluye la membrana. Estoy contento...

Regular filters for watts reverse osmosis and as always easy to install . Regular filter change as recommended by manufacturer makes a difference in process of clean drinking water .

Compre el kit la membrana se descompuso y ya no filtra

These seem to go up in price every single year. The filter system works great but it’s an expensive purchase.
