I have it, and purely ergonomically, it's the best filter I've ever used. It's also quite expensive with expensive filters that need replacing frequently.
Fluoride in your water supply is key to reducing tooth decay. Every medical association every scrap of evidence that we have says it's useful and important. It cuts tooth decay by 25% or so at all ages. You're doing yourself and your family a massive disservice by not adding it back in, never mind causing yourself a lot of pain and losing a lot of money in the long term.

I think it's ironic that people don't listen to doctors when they suggest simple proven methods that have a worldwide consensus behind them and unlimited evidence. But then are willing to let those same doctors drill into their skulls when they're in pain. Don't be that person :)
Some toothpaste have both, Dr jens for example which does have the 10% concentration shown most effective in clinical trials
It keeps fluoride in your saliva. Which toothpaste cannot do.
Which is why you're not supposed to rinse the toothpaste you used to brush your teeth.
I know this is posed as a positive, but I have a feeling in 1000 years we are going to be laughed at like the Romans for putting lead in their wine.
Anyway, my dentist told me to leave the fluoride on my teeth for a few minutes. Wonder if that is more dangerous due to the concentration.
