Crystal Quest Fluoride Under Sink Water Filter System | High Capacity | Reduces Fluoride, Chlorine, Chloramine, PFAS, and More

This is our second Crystal Quest Undersink 8 stage triple filter unit. Our first lasted for 8 years before one of the filter canisters developed a hairline crack and began to leak. The 20K gallon unit works extremely well and is easy to replace the filters when they reach their limit. Definitely have a licensed plumber do the initial installation. Once that is completed, you will easily be able to replace filters, or even the entire unit, on your own.

Our water tastes great and I have the peace of mind knowing my family and I won't be ingesting fluoride in our water. After moving from a house with a well and great, clean water to a house with a municipal water supply, I was shocked by how horrible city water was. We tried a Brita for a long time, but the water still tasted bad and I knew that there were still a lot of additives (like fluoride) and contaminants in it. The Brita also took a lot of space in our refrigerator. This water filter was pretty easy to install. We did have to get an extra water hose to match our water pipe and fitting sizes. Now our water is clean and tastes great! It is nice to have a continuous supply of clean water with good pressure and more room in our refrigerator.

After we had this filter installed, the water had a stronger chlorine taste than our tap water without any filter - and way more chlorine taste than with our old, less expensive filter. We contacted the seller, who responded promptly. He contacted the manufacturer, who had to be nudged a few times, but after a few days responded with a phone call. The manufacturer sent us a new filter for the chlorine.After we installed the new filter, the water didn't taste of chlorine at first drink. But if it remains in a glass bottle in the refrigerator for more than a few hours, the chlorine taste is still there. I've solved it right now by purchasing bottled water for the water we keep in our refrigerator. If we fill a glass from the filter and drink it immediately, there is no taste. But we like our water cold, and the water from this filter tastes quite strongly of chlorine after a few hours. (Our old, less expensive water filter never developed a chlorine taste. I wish we had stayed with that!) But we wanted a filter that removed fluoride from the water. Maybe I'm just a skeptic, but I can't help but wonder if the chlorine filter does such a poor job of filtering out the clorine (which you can taste), is it really removing the tasteless fluoride! We are very disappointed in this product to say the least!I looked into returning the whole unit, but the shipping would be expensive. So, I am going to purchase bottled water and put up with this product for a while until purchasing a different filter doesn't seem like too bitter of a pill to swallow! I certainly wouldn't recommend this one. I would probably give it zero stars if that were an option, except that the seller was prompt and courteous.

We are one of those families that believe strongly that water should not be fluoridated. There is so much evidence that it is harmful. It is the only thing added to water that is designed to treat the person drinking it and not the water itself. Chlorine treats the water making it safe, fluoride does nothing to the water and questionable at best for those drinking it. Anyway, got this and installed. Fairly straight forward. However, the key thing is to read the details and understand that this does NOT remove fluoride to nothing, only reduces it a little. Very deceptive marketing. Our municipal water is 0.7 milligrams per liter (mg/l) fluoride from the tap. Through independent laboratory analysis, the crystal quest filter showed it reduced it to only 0.57 mg/l here at our home. Literature says it reduces it to below 0.5 ppm but I did not see that when I bought it - all I saw was "Fluoride removal". It does do a good job of removing the chlorine and took 1.0 mg/l chlorine to undetected. Water tastes better but again, know up front what you are buying and don't be deceived on its capabilities. You have to be careful not to flow the water through the filter too fast. The slower the better. I installed a shut off valve in line that allowed me to better control the flow rate to their recommended maximum. Takes a while to fill up a kettle.

The media could not be loaded. Sorry if I did not give full detail on the installation but i am happy to say that it is byfar the best thing I have ever done. I'm a Handyman by trade in NYC and I got tired ofbuying water in any store just not to drink the tap water that I hate so much especiallywhen you know that its not the best in the world. So here is what I did I took time in searchingfor fluorinated filtration water systems and I did thank you Crystal Quest.I'm not a big fan of plastic so I used copper all the way and when I was done which took mea little over a hour I couldn't be any happier than a pig in s#it. So I started of with a T-off3/8*3/8*1/4 followed by a Niddle valve(throttle ling valve) and the 1/4" soft copper tube andthe adapter 1/4"(*2) thats hooked up on the sides of the filtration sysytem. Any questions feelfree to e-mail me thnx..

This is the third Crystal Quest filter product I've owned - the first was the countertop Triple cartridge model, which produced the best tasting water of the three, and the other was a countertop Single cartridge model which wasn't good at all. In terms of the taste of the water, this Double cartridge model falls somewhere in b/w - not bad, but not the best.Installation was fairly easy, w/ quick connect plastic fittings (they don't look very strong, but they are easy to install) but after reading the installation manual I'm not sure I trust this thing to stay leak free long term... the manual says water pressure must be below 60psi (it's not so easy to figure that out) and recommends purchasing the optional pressure regulator and leak detector/alarm device ... not very confidence-inspiring. in hindsight, I would say that a countertop model might have been the better/safer choice...
