About This Guide
We’ve lab-tested 68 water filters comparing unfiltered and filtered tap water samples to determine real-life contaminant reduction capabilities – including fluoride. Plus, we checked for NSF certifications and other test data. Turns out, not all water filters can handle fluoride well – far from it! However, some can, especially RO systems. But how to tell which fluoride filters are truly the best? Simple – we did a full analysis!
- Hands-on experience: We set up, used, and maintained each water filter.
- More testing: We performed taste & odor, filtration/dispensing speed, wastewater, and other tests.
- All other product aspects: We considered initial + long-term costs, warranties, additional features, frequent customer complaints, etc.
Based on this analysis, we selected 12 top-performing systems – a curated mix representing all major filter types – to be included in this guide.
