Those fancy Brita and PUR pitchers? They’re great for taste but terrible at reducing TDS. Activated carbon loves chlorine, pesticides, and weird smells, but it lets calcium and magnesium waltz right through.
So if you buy a carbon filter thinking it’s the TDS hero, you’ll be disappointed. It’s like hiring a bouncer who only stops people wearing red shirts. Use it for flavor, not purity. For real TDS reduction, you need something that grabs those minerals by the scruff.
