Water Filtering

Chlorine / chloramine — they repeatedly say they “remove chlorine, heavy metals, rust & other contaminants.”

Heavy metals — part of their advertised “clear contaminants.”

Rust / dirt / sediment / pipe corrosion particles — they mention “rust, microplastics, dirt & rust.”

Microplastics / “tiny irritants / tiny contaminants” — they include “microplastics”

Bacteria & germs (microorganisms) — they claim “bacteria & parasites” among what is removed (though that is more aspirational than clearly proven in specs) Helios Filter

Fluoride, PFAs (“forever chemicals”) — their copy mentions “fluoride, PFAs” in some places.
