Doing everything right and your coffee still taste strange? It could be possible you don’t clean your coffee filters well. It is advisable to ensure your coffee filters are properly cleaned, and I am going to tell you how in a jiffy.

Why do you need to clean coffee filters?

Coffee filters must be cleaned regularly (often after use) to prevent bacteria and molds from thriving. Besides, cleaning helps remove a film that tends to alter the taste of your brew.

It is safe to toss coffee filters in a dishwasher. However, I recommend cleaning by hand so that you can ensure every cranny and nook is clean. Also, washing by hand helps prolong the life of your coffee filter.

It is effortless to clean these filters as you can spot where the stains are. Make sure not to use cleansers that can ruin your filters. I prefer vinegar and baking soda.

Are metal coffee filters safe?

Metal filters are not fine enough to filter everything that is poured into them. That means they allow some coffee elements to pass through, including micro-fines (which leaves sediment at the bottom of the cup) and oils, which are linked to increased cholesterol in our bodies. Specifically, they raise LDL (bad cholesterol). “the harmful type of cholesterol,” says NBC News’ Merritt McKinney. However it’s the oils that slip through metal filters that are really to blame. These oils hold a lot of flavor which can alter the taste of the cup, but they also oxidize quite quickly meaning the taste can change dramatically over the course of drinking it.

Self-proclaimed coffee drinker. I would, on a typical day, start my day by grinding my coffee with a manual grinder and use a French Press as a starter (2 cups), then a pour-over in the afternoon (4 cups). I had my fair share as a barista but I prefer to drink it, not serve it.
