Point of Entry Solutions


Installed in the water entry point of the house, these neat-looking solutions are ideal to treat the water circulating in the whole house.

It is recommended to have Point of Entry solution used together with the Point of Use solution for a secured filtration and safer, cleaner water.

Treated tap water through whole house water filters and water softeners is however not recommended for drinking and cooking. A Reverse Osmosis (RO) filter is necessary.
