Collection: OPUS

OPUS water filtration, purification, and enhancement products have been researched and developed by Aviva's founder Nathan Zassman to fulfill multiple criteria for producing better tasting, healthier water for your household. OPUS Healthy Water Systems produce crystal clear, great-tasting water for just pennies a litre -- removing harmful contaminants, pathogens, chlorine, fluoride, chloramines, heavy metals, odors and more, while still retaining (or in some cases, even adding) naturally occurring beneficial minerals.
