Platypus DayCap Replacement Filter


This replacement filter cartridge by Platypus Hydration is the same high-flow and effective hollow fibre filter that came with your original DayCap™ In-Bottle Filter. Right out of the box it’s ready to twist into place and deliver fast, safe, and easy access to clean drinking water.

Proven Filtration: Hollow fibre filtration media is the same technology as our most popular and field-proven filters, with a flow rate up to 1 litre per minute.
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.**
Easy Cleaning: Simply shake to clean with it attached to your bottle to break up particulates and restore flow rates.
Optimized Design: Filter detaches with an easy half turn for cap-only mode while the semi-flexible carry loop is a sturdy attachment point.

All Platypus hydration products are 100% BPA, BPS and phthalate-free, and do not use polycarbonate
