The water bottle cap that transforms your favorite wide-mouth water bottle into a fast-flowing, ready-to-go water filter.
For when you want to head out with easiest possible water filtration, we engineered the DayCap to seamlessly fit three popular wide-mouth water bottles and turn them into fast, safe and incredibly easy water filters.
• Multi-Compatible: Optimized to fit Nalgene® wide-mouth bottles, HydroFlask® wide-mouth bottles, and Yeti® Yonder™ bottles.
• East-to-Use Design: With a drink spout optimized for pulling water through the filter, all you need to do is tip your bottle up like usual and drink.
• Premium Construction: TPE mold construction is durable and complements the quality of your bottle.
• Proven Filtration: Hollow fiber filtration media is the same technology as our most popular and field-proven filters and filters up to 1 liter per minute.
• Easy Cleaning: Simply shake to clean with it attached to your bottle to break up particulates and restore flow rates.
• Safe & Effective: Each filter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa.*
• Expertly Engineered: Filter detaches with an easy half-turn for cap-only mode; spout shape is optimized for drinking and pouring; semi-flexible carry loop is a sturdy attachment point.
• Cartridge life: 1,000 litres
