In the process of softening water, the water softener will replace the calcium and magnesium ions in the water with sodium ions. Therefore, the sodium content in the treated water will increase. For healthy adults, moderate sodium intake will not have a significant effect on the body.

Assuming you buy a $300 distiller, the average annual operating cost is $280.8 in electricity + $150 in maintenance + $2.4 in water (based on the highest estimate), a total of about $433.2.

UV filters mainly focus on killing pathogens in water, but cannot remove impurities and suspended solids in water, while RO water filters can comprehensively purify water. If there are more impurities and suspended solids in your water source, a reverse osmosis water filter may be a better choice. If the main concern is microbial contamination of the water, a UV filter may be more appropriate.

The price of a reverse osmosis system that can process 20 tons of water per hour is generally between US$40,000-70,000. Its core device is a device that uses the pressure difference of a semi-permeable membrane to purify brine.
