Let’s be real for a sec: every filter eventually becomes a party for microbes. It’s dark, wet, and full of food particles. Your filter is basically a five-star hotel for bacteria. They don’t pay rent, and they stink.
To evict them, clean the housing every time you swap cartridges. Use a mild bleach solution (one teaspoon per gallon of water) and rinse thoroughly. And please, don’t put the filter in the dishwasher. You’ll melt it, and then you’ll have a different kind of crisis.
If you live in a hot climate or keep your pitcher near a sunny window, you’re basically growing bacteria faster. Move it to a cool, dark place. Your taste buds will thank you, and so will your nose.
What About Chloramines?
Ah, here’s a fun fact: some cities use chloramines (chlorine + ammonia) to disinfect water. Your filter might not remove all of it, especially if it’s old. The leftover ammonia can react with other compounds and—you guessed it—smell fishy.
Check your local water quality report online. If they mention chloramines, buy a filter specifically designed to tackle them. Look for a catalytic carbon filter. It’s like the superhero version of regular carbon.
And don’t even get me started on dissolved solids. Heavy metals like iron or copper can give water a metallic, fishy scent. A simple carbon filter won’t touch those. You’d need a reverse osmosis system or a distiller.
