Product Description

From the Manufacturer

This RO Pure replacement water filter kit provides a complete one year supply of filters for your Four Stage RO Pure reverse osmosis system. This kit includes two sediment prefilters (105311), two carbon prefilters (105351) and one carbon postfilter (105341). This is everything you need for a full year of operation. The RO Membrane is sold separately as it does not require annual replacement. The Watts RO-Pure reverse osmosis system consists of a stage 1 five micron sediment filter that traps particulate matter like dirt, rust, and silt that will affect the taste and appearance of your water. Stage 2 is a five micron carbon block filter that reduces chloramines, chlorine as well as other materials that cause bad taste and odors (these are called PRE-filters because they filter in front of the reverse osmosis membrane). Stage 3 is the heart of the reverse osmosis system, the RO Membrane. This 50-Gallon per day semi permeable membrane will effectively reduce TDS (total dissolved solids), Sodium and a wide range of contaminants such as Lead, Arsenic, Perchlorate, Chromium, Copper and Radium. It will also remove over 99.95-Percent cysts such as Giardia and Cryptosporidium.

The RO-Pure filter (and consequently the replacement filter pack) is fantastic. See the (currently) 100% 5 star reviews on Watts Premier RO-Pure 4-Stage Reverse Osmosis System for more details. The 5 stars goes equally to the replacement filter set.

That said, I agree with the other reviewers that the price here (currently ranging from $71.35 w/free shipping, or $76.98 w/Prime eligibility) is not a good deal. Yes, you can order directly from Watts for about $65 plus $10 shipping (making it pretty much a wash, and I'd rather go with Amazon in that case), but I'll point out that if you're a Costco member (where you most likely purchased this unit in the first place), this 5 piece replacement filter set ordered online from them is only $50, with free shipping. So, you can guess where I order this from. Once more, however, just because the price isn't great here does not mean that this product deserves anything less than a full 5 stars. This system is one of the best investments I've made in a long time, and these filters are super simple to swap out.

If you have the Watts R.O system, you need this replacement filter pack. It's available at different prices at different times, so shop around. This is the right number of filters for one year. You also need to replace the green labeled filter every 2-5 years, you can get that directly from Watts or from Reverse Osmosis Superstore online.

I have been using watts for two years almost and up until a month ago I was happy with it. Two months ago my carbon filter got jammed after only three weeks!! I have shipped the clogged filter on my expense to watts and two things happened that we're not cool 1- I got no reply from them in any form to give me the results of the filter test, no email and no phone call. 2- when I called them they couldn't give an answer to why there filter got jammed, I am sorry but if your product fails them man up and take responsibility and offer some relief but this wasn't the case.

This is an awesome one year kit. The cartridges are easy to change with almost no mess. At the one year mark, you do need to follow the product instructions to clean tank out as well. After 2 years, there is a green membrane cartridge Watts Premier original RO-PURE 50 GPD Membrane you need to change (at least if you have the 4 stage) and that is not included with this kit.

We bought this unit of replacement filters 2 separate times. The first time, the reverse osmosis filter broke soon after installing it, like within a few days. The company said it was ' virtually impossible' to have received a faulty unit. So we hired a plumber to look at the filtration system and he was scratching his head at why the water would just barely drizzle out. All we knew was it worked fine before we replaced the filters.
The company gave us a list of steps to try and only then would they consider sending a new part out. So we actually tired everything they said And finally they took back the reverse osmosis filter and guess what, it WAS faulty. They did send us a new one, but we had already spent hours on problem solving and the paid the plumber to come out-- so it was NOT a good deal for us.
The next year, it started not working again ( no water pressure, only a drizzle of water) and by then, my husband knew all the tricks to try and it was that darn reverse osmosis filter again ( the most critical and expensive part). When he took it out, the pressure was fine, when he put it back, it didnt work again.
My husband tried repeatedly to get the company to send a new one. They just did not respond to the many inquires. finally, we gave up. Unit bad, zero customer service.

This is a great product from Watts replaces the old cartridge type that you need a wrench to open and replace the filter media. Easy to replace just a quarter turn to unlock and replace it with a new one in minutes. This kit is good for a year as per watts instructions, 2 first stage sediment filters (1 every 6 months) 2 second stage carbon filter (1 every 6 months) and a fourth stage carbon filter every year. The 3rd stage membrane filter is not included and needs to be changed every 2-5 years depending on water conditions. Yes its true you can buy it from costco for $49.99 plus tax as I did...but this is still a great product!

Just what I need for my RO system annual filter change - includes everything but the reverse osmosis filter, which lasts about 5 years
