Why not just buy a regular filter bottle?
No squeezing, no waiting
Most filter bottles need you to squeeze or pre-charge. This one filters at natural drinking flow rate.
Heavy metals included
Cheap bottles skip ion-exchange. Yours removes lead, mercury, and copper — the silent contaminants.
Mineral re-mineralization
Filtration usually strips good minerals. The final stage adds calcium, magnesium & potassium back.
