Why does my new system sound like it is sucking air when run for a few minutes

What is the waste ratio on this?

Asked by: Mo
RO units are designed to produce "reject" water; it is not wasted. It is high in dissolved solids which is what you want to remove. The gurgling sound I read about is normal in many units. Some units are quieter than others is all. There could also be an issue with the drain line to the sewer; if it is too low it can gurgle more and even cause water to leak from the hole at the base of the faucet (it is designed to do that). All RO unit manufacturers deal with the same issues. I just installed this Brita unit and it gurgles while is works...not a deal breaker. If you want RO water you must produce reject water: live with it or drink tap water. Bottled water contains RO water and that means the bottler sends lots of reject water down the drain. You cannot get around that.

How often do you have to change the filters?

How often do you need to change the Redi twist filter USF-201 and Redi Twist filter USF-205 . It says 1 year filter life, Does that mean all three need to be changed yearly? Thank You
Asked by: ashune566
Hello @ashune566. Those two filters should be changed every six months, or as needed. The RO membrane should be changed once a year. If you have any other questions, feel free to give us a call Monday - Friday, 9 am - 5 pm EST at 866-709-7086. Thanks! - Meghan, BRITA, manufactured under license by Protect Plus

Does this filter out flouride?

Asked by: Luke
Yes. Fluoride is a volatile organic compound or VOC. So is chlorine. An RO filter equipped with an activated carbon pre filter does take out VOCs. Mostly to protect the RO membrane.

Customer Reviews

Redi-Twist 3-Stage Reverse Osmosis Drinking Water Filtration System is rated 2.3 out of 5 by 42.
Rated 5 out of 5 by from works like a clock OK guys I'm writing this review because I see so many noise/water gushing/leak issues. I had the same issue as most of you guys that are here with 1 star rating (I thought I was doomed to the sound always being there) but my fix was simple and easy. My error was that I missed the little pressure reducer!!!! As soon as I put it in there was peace and quiet at home! Now if you have the same issue please verify that you have everything installed properly. God bless.

Rated 2 out of 5 by from Barely adequate RO system. It works, but for how long? This Brita RO system is the fourth reverse osmosis system with which I have experience. The previous RO systems were: a Pentek 4-stage system that was already installed in the home I bought; an expensive Culligan 3-Stage system that was installed in a condo we purchased; and a Watts Premier 4-Stage RO system that I bought back in 2007 to install in my motorhome. The difference between a 3-Stage and a 4-Stage RO system is that a 4-Stage system includes a sediment pre-filter in addition to the carbon pre and post filters and the RO membrane. I ordered this Brita Redi-Twist 3-Stage Reverse Osmosis System to install in a house we are remodeling. My first impression of this system is that it is cheaply made for the relatively high cost of the system: everything is made of plastic except the faucet spout, the storage tank, and a few screws. Unlike all the other systems mentioned, the storage tank connection does not include a built-in ball valve to shut off the water at the tank when necessary. Since the tank is pressurized, this means that if you disconnect the line that goes to the tank, water can squirt out of the top of the tank connection. The second indication of this system's poor quality came on page 3 of the USS-335 Installation Instructions booklet which says "Replace system every 5 years." Even though the system has a 3 year limited warranty, having to replace the entire system every five years seems excessive. If you are replacing the filters every 6 – 12 months as recommended there is no reason the entire system should fail after only five years unless the system was designed for obsolescence. My Pentek system is over 20 years old and the only major part I've had to replace is the storage tank and it is still the only RO system that doesn't gurgle for hours after filling up my Brita water pitcher. One of the drawbacks of this Brita 3-Stage RO system is the lack of a sediment pre-filter which leaves the sediment filtration to the carbon pre-filter. As noted on page 22 of the Installation Instructions, "You may need to replace these filters more often (than every 6 months) … with a high level of incoming sediment. This will protect the RO membrane from being destroyed by chlorine and plugging with sediments." Of course, you can always install a separate sediment pre-filter anywhere in the cold water supply line before it reaches the RO system. The design of the Redi-Twist filter cartridges with two separate small O-ring sealed connections increases the likelihood of leaks. In contrast, the Kwik-change connection of the Watts filter cartridges features a single larger diameter O-ring sealed connection point at the top of the filter. A further concern is that the Redi-Twist RO membrane cartridge has the drain port coming out of the bottom of the cartridge. In order to replace the RO membrane cartridge, you have to disconnect the drain tubing from the drain port. Most other systems include the membrane drain port in the header where the filter cartridges attach. Installation of the Redi-Twist RO system is pretty similar to most other RO systems: you install the drain saddle connector to the sink drain, mount the filter system assembly somewhere close to the faucet and tank in the sink cabinet, find a place for the storage tank under the sink, install the RO faucet in your sink deck, install a tee (adapter) in your cold water line under the sink, then connect everything together with a combination of ¼-inch and 3/8-inch plastic tubing. Although the plastic tubing for this system is colored red and white to simplify making the necessary connections, the Watts system goes a step further by color coding their tubing in red, black, green and blue. Finally, you must sanitize the whole system by running a small amount (3 ml) of bleach through it and letting the RO faucet run for 24 hours. (This seems a bit excessive. Most systems only require emptying the tank twice before using the system.) Do not forget to install the flow restrictor in the membrane end of the red tubing that goes from the drain port of the RO membrane to the RO faucet. What I like about this RO system is the convenience of being able to replace filter cartridges by simply twisting them 90 degrees and pulling them out. However, this convenience comes at the higher cost of the filter cartridges versus filters that fit into a reusable container where you are only replacing the filter media.

Rated 5 out of 5 by from Easy change filters! No more mess! Gone are the days of having to get a bucket out and and the mess of water spilling under the sink when it was time to change your RO filters. I can change out mine in a matter of minutes, not a drop of water spilled. Also no greasing o rings and hoping that the filter houses did not leak. As for the quality of these they are in fact well made. Strong thick plastic will insure a long lasting product. The most important thing of course would be the taste and quality of the water, you will not be dispointed. It tastes wonderful and is very clean.

Rated 5 out of 5 by from Very nice investment This R O System is great. As I had come across some health issues I was on the market for one. All Others I checked out were very pricey. This system takes out the bad stuff in the water. Many cities add chemicals to the water. Not Good. The water tastes so much better and is so much better for your body than with out it. It is very easy to install. The system does take up some space under the sink. Not a big deal if you want good water. The filters are cheaper than most also. I would recommend it to anyone.

Rated 4 out of 5 by from Taste great! Some of the best tasting water i have had yet. I live outside of our local major metro, so we do not get the same tasting water as them. Our water in our town is a bit harder and needs assistance, and this system does the trick. For a long time I have been accustomed to just filters on the refrigerator. This completely changes that game. If you do the same... get one of these systems now! You wont regret it. Fast and easy to install with the push in mini pex style tubing and a few screws overall. At first you have to wait a bit for the water tank to get full then it's on. Does take up a little bit of room under the sink, but well worth it. easy to follow instructions. May i suggest when installing it, think about where you will be putting it, so when you do need to change the filters, the can be easily accessible.

Rated 4 out of 5 by from Compact for easier fit Brita is an excellent brand which can be trusted to put out a good product. With that being said the cartridges are small enough to be used in a camper/motorhome along with the holding tank. Hook up to the r/v water connection and now you have potable water. No need to haul excess water where not needed. The cartridges are a little on the expensive side but your not using this to wash the car and laundry, but under the sink for drinking/cooking water.

Rated 5 out of 5 by from Great Tasting Water! We installed this in our office so we could safely drink the tap water. The water tastes amazing now! and I noticed that our plants are growing lots of new leaves so I think it must be the water that is causing this positive change. We have only had it installed for a few weeks so I can't comment on how long the filters will last before needing to change them, but recommendation is 6 months and 1 year for the membrane. Overall the unit seems made of adequate material except the faucet spout which feels cheap, but we are using it anyway until it needs to be replaced. It took two people reading and installing to get this properly installed so I would not say this would be easy for a complete beginner. We do lots of projects and this was a little challenging at times. I like the simplicity of changing the filters when the time comes. No tools required to do this part.

Rated 1 out of 5 by from Bad product, bad instructions, does not work Unit does not filter water, just drains all of it out. Hired a plumber to install the unit. Followed the instruction to drain water, instructions not very precise. Tried different things, including leaving the water on for a many days - which results in water just draining away. Instruction says 'Leave the auxiliary closed', however nowhere in the instruction/product documents does it say what they mean by 'auxiliary'. Disappointed with Brita, should have read the reviews before i bought.
