What contaminants can Viomi RO water filter system reduce?

Is RO water bad for the health?
The RO does not make the water unhealthy in any way. Instead, the purification process may protect the body from many contaminants present in the water.
Do I need plumbing services to install the reverse osmosis system?

This video explains how to install Viomi RO system.
What’s the difference between tankless and tank reverse osmosis systems?
Tank reverse osmosis system holds reverse osmosis water so you have plenty to use when you need it. A traditional tank RO system makes water slowly. It takes one minute to produce two to three ounces of RO water. If you were to turn on your faucet for a glass of water at the actual membrane production rate, then you would have to wait at least 5 minutes for it to fill. Viomi tankless RO system has overcome the issue of bacteria colonizing in the bladder tank. With no storage tank to fill, Viomi tankless reverse osmosis system does not run until RO water is needed.
Can the reverse osmosis system be used for hard water?
The RO system will not be suggested used for hard water. If your feed water is hard water , you may need to install prefilter and a NOT salt based softener or scale inhibitor prior to the system.
