- After each use, gently rinse filter with water only. The use of soaps may bind to the pores spoiling future beverage flavor.
- Gently rinse until the water coming from the bottom of the filter runs clear.
(clogs dissolved by boiling + baking soda)
Since the holes of filter are fine, clogs form with repeated use.
If the flow rate is low even after pouring boiled water through filter several times, that means clogs are beginning to form.
Here's an important maintenance technique in order to unclog the filter.
Fill a microwave-safe bowl with enough water, put baking soda (2 spoons) in a boiling pot, and heat in the microwave(500W/5 minutes, 700W/3 minutes). Or, boil the filter for 10 minutes.
- Please be sure that the top of filter is facing up.
- Before use, please rinse well with warm water to clean off the baking soda.
- Please be sure to use baking soda that is sold as safe for human consumption(i.e., sold for use as a food additive or as an antacid).
- The filter will be extremely hot after boiling. Please be sure to let the filter cool before touching.
- It will cause breakage if cooled too quickly.
- In some cases, there may be no improvement if not boiled for an enough period.
