There are a few different methods you can use to remove fluoride from water cheaply. Here are a few options:
- Boiling: Boiling water for at least 20 minutes will cause the fluoride to evaporate and leave the water. Keep in mind that this will also remove other beneficial minerals from the water.
- Activated alumina: This is a type of filter media that is specifically designed to remove fluoride from water. You can purchase activated alumina filters online or at some home improvement stores.
- Reverse osmosis: Reverse osmosis systems use a semipermeable membrane to filter out fluoride and other contaminants from water. These systems can be somewhat expensive, but they are highly effective at removing fluoride.
- Water distillation: Distilling water involves boiling the water and collecting the steam, which leaves behind any impurities, including fluoride. This method is effective, but it can be time-consuming.
It’s important to note that some of these methods may not be suitable for removing fluoride from large volumes of water. If you need to remove fluoride from a large amount of water, it may be best to contact a water treatment professional for help.
