Your RO system has a few stages. They catch all the nasty stuff: sediment, chlorine, and weird mystery particles. Over time, those filters get clogged with all that gunk.
Think of them as tiny, hardworking sponges. If you don’t swap them out, your system chokes. You’ll get slower water and—gulp—less effective filtration.
And the membrane? That’s the heart of the system. It’s the fancy semi-permeable wizard that actually strips out dissolved solids. Let a dirty pre-filter ruin it, and you’re buying a new membrane. That’s an expensive sad day.
