Your tap water isn’t just H2O. It’s a party. A mineral party. We’re talking calcium, magnesium, potassium, and sometimes not-so-fun guests like lead or nitrates. That’s your TDS.
High TDS doesn’t always mean bad water. In fact, some of those minerals make it taste great. Ever had spring water that felt “smooth”? That’s the TDS doing its job.
But here’s the catch: too many uninvited guests (like heavy metals) and the party gets dangerous. Your filter’s job? Kick out the bad ones while keeping the good ones. If you can.
The TDS Meter: Your Water’s Gossip Meter
You can buy a little gadget called a TDS meter. It looks like a thermometer on steroids. Dip it in water, and it spits out a number. Zero is pure, boring water. 500 is... well, like drinking from a muddy puddle.
Most tap water sits between 100 and 400. That’s normal. But when your water filter claims to “reduce TDS,” it’s basically saying, “I’ll bring that number down, buddy.”
Does a low TDS number mean your filter is working? Not always. Sometimes your filter needs some TDS to function. Wait, what? Let me explain.
What Is TDS in Water and What Does it Indicate?
