Ozone water purification is surprisingly fast — much quicker than chemical tablets or filters. With the Ozo-Pen®, you can treat 8, 16, or 24 ounces of water at the press of a button. Each cycle takes just 1–3 minutes, depending on the volume. The GO3® Ozone Cap, made for the wide-mouth 1-liter Nalgene® bottle, purifies up to 32 ounces (1 liter) in about 3 minutes.
By comparison, purification tablets can take 30 minutes or more, and filters are slow to pump or sip through. Ozone technology gives you fresher-tasting, safer water quickly — without chemicals, aftertaste, or clogged filters.
It’s important to note that ozone also needs a short dwell time after treatment. During this waiting period (about 3 minutes), the ozone continues to work to inactivate microorganisms. Our devices make this simple — the light flashes yellow during dwell time, then turns green when your water is ready to drink.
