The OeauO unit uses an innovative filtering process that filters municipal tap water to ensure pure, safe and healthy drinking water. After simply filling the machine with tap water and inserting its special Safe Water Capsule, the Opresso filter technology can do its job. The tap water is first filtered by a Sediment filter and a Carbon Block filter to remove sediments and undesired odors like chlorine, and to improve colour and taste. After this, the unique Safe Water Capsule removes all possible micro-organisms from the tap water, making it safe to drink, 100% of the time!
OeauO’s revolutionary filtering process produces the best & healthiest quality drinking water there can be. Each Safe Water Capsule can filter up to 20 liters of municipal tap water per day which makes it a sustainable alternative to single-use plastic water bottles and therefore helps to keep our environment clean, green and healthy!
