Comments: Worked great in a Kent RODI system.

Comments: Good!

Comments: Works like a charm. 0 TDS water right away. Just ordered another set.

Comments: These are easy to install and my TDS dropped from 53 to 6.

Comments: The filter works as specified. I had to cut part of the rubber off of the carbon block to get it to fit in my GE clear canister chamber. I wish the specs would show the life expectancy in total gollons.

Comments: Very cost effective filter kit that works great!

Comments: Seems to do a good job. A good value over the costly "name brand" filters.

Comments: Wish I had bought more of these at the sale price! Fit is perfect in my Abundent flow system

Comments: Very good price nice filters website is the best with quick shipping

Comments: second time i have replaced,work well.clean water real good

Comments: I bought the 3 piece replacement cartridge set and within 10 minutes of running my
<br />tds was lowered from 9 to 0 (ZERO)!
<br />Great produce, priced right, easy instll

Comments: Very good product.

Comments: Did what i wanted it to do at a low cost.

Comments: The replacement filters are of first rate quality. They were a perfect fit for my Kent RO/DI. Pay attention when installing the mixed bed DI cartridge, the top is not labeled and the cartridge must be installed right side up. If you don't you will not receive RO water from your membrane. Make sure the closed cap end is placed in the bottom of the canister. This product is well worth it, best psi ever from my unit.

Comments: It was an easy replacement process- seems like a great product- will buy it again next time the need arises.

Comments: The RO/DI replacement kit is a really good product for the money. This was my first replacement kit and it was very easy to change the filters.

Comments: The filter kit is great

Comments: Have purchased many different cartridges and this is just as good as any of them. Great price and fast shipping. Thanks again,

Comments: This is my 3rd order of these filters and I have been extremly pleased with the water quality and ease of replacement. I use an inline TDS meter and when I hit 1 I replace all the filters. These filters usually process severval thousand gallons of water for my 275 gal system before I have to replace them. I use these filters in a 50gpd spectre pure RO/DI 4 stage. If your looking for good filters look no more

Comments: I got this kit to renew my Kent Marine Hi-S 35gpd system. There is no indication of which way the various cartridges are supposed to be installed in the filter cylinders - a simple "up" arrow would've been nice. I had no problem with the sediment filter and carbon block, but the DI cartridge doesn't seem to fit or work properly. I've got the gaskets in place (one @ each end) but the cylinder never fills with water. I can see the water dribbling down the inside of the cylinder, and it does make its way thru the DI cartridge, but since the cylinder never fills with water I have a feeling that the water is "channeling" inside the cartridge, which is not efficient, plus I can't see when the color of the media changes. I won't get this one again; I wonder if I can return just one out of the three cartridges? I'll get a real Kent Hi-S DI cartridge next time.

Comments: just what i needed. called and ordered, and very easy to install. now my TDS is at zero out. at first I didn't know how to change them, but when I called and talked to Customer Service, they explained what to do when I got them and it was very easy to install. Oh did I say that already..good service.

Comments: Good price, arrived quickly

Comments: High quality membranes for a good price, can't really complain about it. My RO/DI unit had been in storage for about 3 years, so I obviously needed to replace the membranes. Ordered this kit, popped them in and flushed it out. They work great, and with our western New Jersey red clay spring-water it's a necessity.

Comments: I've purchased this kit a number of times now - and it's about the easiest way to replace the main filters for my Spectra-Pure RO/DI system. Beats ordering each one separately.

Comments: Works great. Will order again when I need to replace the filters again.

Comments: The filters are great, however, I had an unbelieveably difficult time unscrewng the containers that hold them. However, now that they are up and running we're back to getting high quality water.

Comments: My ro/di unit's output increased 50% after changing all 3. I will do this yearly.

Comments: I like this product.Works like a charm.

Comments: this is a good product that is well packaged very fast shipping

Comments: i WAS EXCITED WHEN MY NEW R/O REPLACEMENT KIT ARRIVED. THIS KIT LOOKS LIKE IT IS MADE OF THE HIGHEST QUALITY MATERIAL AND I COULD NOT WAIT TO START MAKING PURE HIGH QUALITY WATER.

Comments: YES!!! I love how you have all three filter kit in low price. If you have an RO/DI unit I would recommend getting this product. And the best part of it is low price.

Comments: Very Good!

Comments: I've been using these filters for over 2 years and they do a great job. The TDS meter shows "0" until it's time to replace them again. The DI filter changes color as it's being used up, so I know when to get another one.
