Replacement filter for a Vapur Microfilter bottle. Hollow tube technology creates clean water as you squeeze the bottle, or suck on the drinking straw.
- Hollow fiber membranes are polyethersulfone, coated with hydrophilic polymer to aid filtration.
- Filter life depends on water quality. A mechanical stop feature closes at the end of the filter's life to prevent failure.
- Uses no batteries or moving parts.
- Reduces turbidity by filtering particles of approx 0.2 microns.
