Multi-Polar Reversal Vibration Magnetic Field Water Mag Sofia This is an excellent water purifier that can be used to filter rainwater, etc., in the event of a disaster. I have taken everything out and checked it, and it is an unopened item. *Because I purchased this during a period when the large nut was missing, it has been delivered separately. Please install it according to the supplementary instructions. *Please be sure to check if it can be installed on your home water faucet before purchasing. https://bioaroma.jp/product_magsofia.html Features of Mag Sofia 1. Low cost Since it does not use electricity, there is no electricity bill and it does not break. Only cartridge replacement once every 6 years for a household that uses 20 liters per day. By specially combining permanent magnets, it generates torus energy and perpetually generates magnetic waves, creating oxygenated water similar to natural spring water. 2. Safe and secure By adopting a water diffusion plate filter, it diffuses in a mist-like manner without creating a water path, and 100% of the activated carbon's performance is used for filtration. It also filters coral filter media, etc., creating water rich in minerals that is easy to drink and delicious. 3. Usable in case of disaster By removing the cover, removing the cartridge, and reattaching it in reverse, and flipping the cover over and replacing it like a bucket, you can drink safe and secure water filtered from river water, etc., in the event of a disaster (the fact that it does not use electricity is also useful here).
