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.

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

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.

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.

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.
