Drinking Water can be produced and consumed from the convenience of your own home through the safety and convenience of a whole-house water filtration system. Drinking Water Systems include Reverse Osmosis, Alkaline Water Ionizers, In-Line Water Filters and Water Pitchers. Reverse osmosis filters are usually installed under the sink and have a separate spigot for dispensing clean and healthy water. There are also countertop water filters that can be used in rental communities and apartments or to save some space under the sink. Alkaline Water Ionizers are the perfect choice for those who look into clean drinking water with additional benefits as high pH level and negative ORP (oxidation reduction potential).
