2 Signs That Shows Your Osaka Coffee Filter is Clogged Up

If you are regularly making a coffee using Osaka pour over coffee maker, then you might have experienced few issues with it in the first 1-2 months.

One of those issues is clogging of Osaka metal filter.

This cone shaped metal filter often clogs up if you don’t maintain its cleanliness properly.

After making every pour over coffee with this Osaka method, you will need to carefully clean and wash the cone filter.

There are 2 main signs which will tell you if the Osaka coffee filter is clogged up or not.

1. Extremely slow coffee dripping: When the stainless-steel mesh filter is clogged, no matter how coarse coffee grind is, it won’t drip quickly through it.

When you experience that the coffee is dripping really slow through the Osaka filter, then you must realize it is time to clean it up properly.

2. Brown and nasty looking mesh: Another sign that confirms the clogging of your coffee filter is the existence of browny and nasty looking coffee oil residue marks on the mesh filter.

When you hold this coffee filter in the bright sunlight, then you will see inconsistency in the mesh pattern.

And you will not be able to see through the filter properly due to coffee oil residue.

This is another sign that tells you it is time to quickly clean your mesh filter.
