Aji Filters: The Easy-to-Clean Reusable Cotton Coffee Filter

Coffee lovers understand the importance of having a quality coffee filter. Reusable coffee filters provide a cost-effective and eco-friendly alternative to disposable paper filters, as they can be washed and used again. However, knowing how to properly clean and dry a reusable cloth coffee filter is essential to maintain its quality and avoid potential issues like mildew growth.

Aji Filters are a super easy to clean reusable cotton coffee filter. Unlike other filters, the hand-loomed fibres are much tighter and barely hold onto the coffee grinds, particularly when wet as the cotton turns into a silk-like texture. This makes it easy to rinse away the remaining coffee grounds under just the pressure of a running tap.

To clean an Aji Filter, simply follow these steps:

1. Discard the coffee grounds into a bin or compost.
2. Turn the filter inside out and run it under running water until all of the coffee grounds are gone.
3. Gently scrub the filter with your hand to remove any stubborn coffee residue.
4. Wring out the filter a couple of times.
5. Your filter is now clean and ready to use again!

If you want to store your Aji Filter until the next time you brew, you can keep it in a glass of water. This will help to prevent the filter from drying out and becoming brittle. You can also store your filter in a test tube, which is easy to write on, easy to transport, and perfectly fine to use in the fridge. If you are using your Aji Filter daily, don't worry about keeping it in the fridge. We only recommend storing your filter under water and in the fridge when you plan on not using it for longer durations.
