Question: Does this RO system remove flouride?
Document: I have very hard water in my area (around 20 gpg, +/-), and our city has very poor quality water as well; sometimes it even smells and tastes like bleach has been mixed into it. I am quite paranoid about the quality of my coffee. I wanted a system that would remove impurities, and yet, I needed something that would add minerals back to the water to help create the right extraction, as well as balance the pH. The Artesian Tapmaster RO system does just that.
We have had our filter installed for about a week now and I love it. The water tastes amazing and clean. We had the brita filters before and I hated that they couldn't remove all the chemicals in the water, including fluoride. I am so excited that we are no longer drinking the waste that this country puts into our water!My husband, while installing, watched the video's on youtube b/c apparently the direction aren't the greatest and a pipe hookup was wrong.
Installation was easy, although reaching up to remove the soap dispenser from under the sink and installing the faucet was somewhat of a challenge. I left all tubing full length, just in case I decided to return it.After flushing the Tap Master TMAFC 3 times, I took a small glass of Nestle and a small glass of the filtered water to my wife, being careful to not identify to her which was which. I asked her which one was the Nestle.
I'm a health care provider and had been suffering with insomnia. I learned that insomnia can be magnified by fluoride plaquing on the pineal gland (small gland in the brain that produces melatonin). After no success with conventional western medical interventions (sedatives are addictive and ultimately, don't solve the problem), the first order of business was to stop my exposure to fluoride which is in most city tap water. The only way to remove fluoride is through reverse osmosis.
We like the Tap Master TMAFC so much, just ordered another one for my parents as a gift. After drinking Tap master water, we don't want to drink anything else. We live in a area with highly chlorinated water. This resolves the problem nicely. I also wanted to remove any possible fluoride and other contaminents (see mercola.com for more info on fluoride)  The Tap Master also re-mineralizes the water. Tastes like really good spring water.
Love this thing and can no longer imagine life without it!!!! My final thoughts if you are considering an RO system. Stop looking and just do the Tap Master. You won't be sorry.
This RO system has made an incredible difference in how much water my family consumes. Installing this system in our home is by far one of the best upgrades we've done in a while.
I have been sold on the purity of distilled water but when it burned out (again) I was willing to try a RO system. Leary of stories about RO versus Distilled, I sought out the best, Tap Master for my choice.
I had this RO system in my Amazon wish list for a while. It seemed like the system with the most positive reviews, although it was pricey compared to the others. The replacement filters don't seem to be sold on Amazon, but they are available from the manufacturer directly, for about $80.
We purchased this system to replace  and earlier version of the RO system and the improvements in taste and water quality are pronounced. Also, we purchased the 4 gallon tank upgrade as our household drinks a lot of water and the old system was limited. We had to await the old tank filling.
Answer: yes
