DayCap™ In-Bottle Filter
DayCap™ In-Bottle Filter
Transforms your favorite wide-mouth bottle into a fast and easy water filter.
- Easy-to-Use: The drink experience is practically the same as without the filter thanks to the high-speed filter and the flow-optimized spout.
- Proven Filtration: Hollow fiber filtration media is the same technology as our most popular and field-proven filters, with a flow rate up to 1 liter 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.
- Premium Materials: TPE mold construction is durable, grips well and complements the quality of your bottle.
Comes with DayCap cap and removeable filter cartridge.
*Includes Giardia, Cryptosporidium, E. coli, Salmonella and Cholera.
Tea-colored water typically has a high concentration of decaying vegetation adjacent to, or in, a water source, resulting in a variety of organic acids. These acids, and the accompanying water conditions, are very hard on ALL types of water filters. Get your water elsewhere if you can.
However, if no alternatives exist, we recommend backflushing/cleaning your filter more frequently, even after each use. This will help minimize the clogging of the filter.
A DayCap that has been recently used to filter water will have wet hollow fibers, which can freeze and break the fibers. Broken fibers no longer filter water. It is important to prevent hollow fiber filters from freezing.
If you are expecting freezing or near-freezing temperatures, we recommend carrying or stowing the filter cartridge near your body (e.g., in a chest pocket) and bringing the filter into your sleeping bag overnight. (Place it in a plastic bag to prevent it from leaking).
If you think your filter may have been damaged by freezing, perform a filter integrity check before the next use to determine if it is still safely filtering water (see instructions for your filter product). Consider carrying a replacement filter as a backup in case of a failed integrity test.

Designing for Durability, Longevity, and Repair
We build products to last, offering outdoor enthusiasts more adventures and reducing the amount of goods piling up in landfills.
Product Durability
Our priority is to design and manufacture durable, long-lasting products. Extensive testing—both in-house and in the field—allows us to ensure that our products will stand up to the wear and tear to which our customers subject their gear.
Our products have stood the test of time, and we often hear stories from customers who are still using their MSR stoves from the 1980s or their Therm-a-Rest mattresses from the 1970s. Because we believe that our outdoor gear should support you on adventures for years to come, we offer a limited lifetime warranty on all our non-electronic products.
Product Care and Repair
Most of our products are repairable by customers or service staff at our Repair Shop. This helps keep your gear in the field and out of landfills. Furthermore, our repair team shares knowledge with customers to empower them to repair their own gear in the field using one of our repair kits included with many of our mattresses or service kits made available to them.
Our repair and service team has more than 50 years of combined experience and has been featured in Outside Magazine for their work. With their creativity and technical expertise, most of the products that get serviced and repaired are returned to customers for many more years of use.
