Description

You’ve already got the water bottle, now you just need the clean water. The DayCap In-Bottle Filter seamlessly fits onto three popular wide-mouth water bottles—Nalgene®, Hydro Flask®, and Yeti® Yonder™—and transforms them into fast, safe and incredibly easy water filters. The removable filter utilizes the same hollow fiber technology as our award-winning backpacking filter systems to filter water safely and quickly. By only lightly pulling water through the spout, the speed of the filter allows you to drink as you normally would from your bottle. If the flow begins to slow down, simply shake your bottle with the DayCap and filter attached to clean it and restore the flow rate. Made of premium materials, the cap is durable, and features a sturdy loop for secure hanging and carrying. The spout is shaped to optimize flow and provide a natural drink experience. It has a flip-up leak-free cover that stays out of the way when you’re drinking. In cap-only mode, the DayCap works as a perfect everyday cap for your bottle when you’re not on the trail. With the filter on, whether it’s a day hike or a backpacking trip, the DayCap In-Bottle Filter makes worry-free hydration as easy as scooping and drinking.

FAQs and Documents

With which bottles is my DayCap compatible?

The DayCap is compatible with the following wide-mouth water bottles: Nalgene® Wide Mouth, Hydro Flask® Wide Mouth, Yeti® Yonder™, CamelBak® Wide Mouth.

How often should I clean my DayCap?

That often depends on the clarity/quality of water being filtered. However proactive cleaning will keep your filter flowing faster for longer. Use your best judgement but consider quickly shaking it clean each time you fill your bottle with dirty water.

Do any of your products contain BPA, BPS, phthalates, or use polycarbonate?

No. All Platypus hydration products are 100% BPA-, BPS- and phthalate-free, and do not use polycarbonate.

Will the DayCap filter remove unpleasant tastes?

No. Hollow fiber filter media does not remove tastes from water.

How do I disinfect my DayCap filter?

To disinfect your DayCap Filter and water bottle, make a bleach solution in the bottle by combining 3mL (or approx. 1/4 tsp) of bleach with 1L of clean/clear water. Then perform a shake-to-clean procedure (see instructions). Then, allow the bottle to sit on its side for 30 minutes, then roll the bottle to the opposite side and allow the bottle to sit for another 30 minutes.

Is the DayCap in-bottle filter dishwasher safe?

The cap component of the DayCap is dishwasher safe. The filter component IS NOT dishwasher safe. A dishwasher cycle will permanently damage filter cartridge and make it unsafe to use.

Are there any issues with using the DayCap in-bottle filter in freezing conditions?

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.

What if my DayCap takes a hard drop?

Hollow fibers can break due to impact. Once broken, they will no longer safely filter water. Often your DayCap Filter will be protected from impact by being inside your bottle, but in the event of it directly hitting the ground, perform an 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.
