Natural water filters can be a useful tool for anyone who wants to ensure that they have access to clean drinking water in the event of an emergency. There are many types of natural water filters, including carbon filters, reverse osmosis systems, and UV filtration devices. These are all effective at removing pollutants from water without the use of harmful chemicals or materials.

Some of the most common natural water filters are activated carbon and reverse osmosis systems. Both filter out pollutants such as volatile organic compounds, pesticides, nitrates, hydrogen sulfide, and metals through a process called adsorption.

Activated carbon absorbs these contaminants through chemical reactions. They also help remove aqueous salts, bacteria, and viruses.

Reverse osmosis filters are also effective at removing chemicals from water, such as PFAS or “forever chemicals.” They force water through a semipermeable membrane, thereby removing these substances.

Forever chemicals are synthetic compounds that can seep into water supplies from landfills and factories, affecting the health of those who drink it. They can cause serious problems, such as reproductive organ damage and respiratory issues.

A simple natural water filter can be made from a plastic bottle and diatomaceous earth. It is easy to make, and a great way to keep those cans out of the landfill.

If you want to learn how to make a natural water filter, there are several simple plans online. These can be a fun project for the whole family to do together, and they can give you access to clean water in an emergency.
