Now we hit the reverse osmosis membrane. This is the brain of the operation. It pushes water through pores so tiny that only water molecules fit through.
Fun fact: Those pores are 0.0001 microns wide. That’s smaller than a virus. It literally rejects lead, arsenic, and even some bacteria. Your faucet water is now cleaner than bottled stuff.
But the membrane is a diva. If you skip replacing the first three stages, it gets clogged with gunk and quits. Treat it right by swapping it every 2-3 years.
Stage Five: The Final Polish
Last is the post-carbon filter. This is the cherry on top. It gives your water that final, crisp taste before it hits your glass.
Imagine you just baked a cake. This filter is the icing. Without it, water might taste flat. Swap it annually, and watch people ask, “Is this from a fancy tap?”
