Do Water Filters Remove Fluoride?
Fluoride in tap water is a hot topic in Australia. It's added to most public water supplies to help prevent tooth decay, but not everyone wants it in their drinking water. Whether for health, taste, or personal reasons, many people in Sydney and across the country are asking: Do water filters remove fluoride?
The answer is yes — but not all filters are designed to do so.
Most standard carbon filters, like the ones in jugs or basic under-sink systems, do a great job at removing chlorine, taste, and odours, but they won't remove fluoride. To actually reduce fluoride, you need a filter designed for that specific job.
If you're serious about removing fluoride from your tap water, here are the most effective options: Reverse Osmosis (RO) Systems
These are widely considered the most reliable way to reduce fluoride. A high-quality reverse osmosis system can remove up to 95–97% of fluoride, along with other contaminants like heavy metals, chlorine, and nitrates.
Local providers like 'Filpure' offer reverse osmosis systems tailored for Australia & Sydney water, which contains fluoride and other common additives.

These are sometimes used in countertop or whole house systems. They're effective but less common than RO systems and typically slower.

Another fluoride-removal method, though not as widely available in Australia.
If fluoride removal is important to you, always double-check that the filter you're buying is specifically tested for it. Just because a product says 'removes chemicals' doesn't mean it tackles fluoride.
Fluoride is considered safe and beneficial for dental health at low levels, according to Australian health authorities. However, some people are more sensitive to it or prefer to avoid any unnecessary additives in their drinking water, especially for infants, people with thyroid issues, or those already getting fluoride from other sources.
It really comes down to personal preference.
If you're looking to remove fluoride from your tap water in Sydney, a standard jug filter won't cut it. A reverse osmosis system is your best bet for clean, fluoride-free water. Many locals now choose this type of Sydney water filter not just for fluoride removal, but also for improving overall water taste and purity.
