ALpHA® BW1 Polypropylene Microfiber

The ALpHA® BW1 is optimized for maximum performance, safety and economics in protecting bottled water from Cryptosporidium and Giardia contamination.

The ALpHA® BW1 filter has been tested and approved per NSF Standard 53 as an absolute barrier to Cryptosporidium and Giardia in potable and drinking water applications. It also complies with the CDC/EPA recommendation for using absolute-rated 1 µm filters to control Cryptosporidium in drinking water.

In order to ensure consistent, reliable filtration performance, Meissner tests each BW1 filter during manufacture. Each BW1 filter shipment contains a Certificate of Conformance certifying the quality of that product lot.

The 1 µm absolute-rated, BW1 pleated filter cartridge provides unmatched filtration performance. It contains a self-bonded microfiber filter medium composed of multiple layers of successively finer fibers and smaller pores. This highly porous, tapered pore structure provides superior flow rates and high throughputs, while maintaining an extraordinary dirt holding capacity. The filter’s rugged, all-polypropylene construction withstands everyday hydraulic challenges in bottling applications.

The BW1 filter can be repeatedly hot water sanitized or inline steam sterilized. It withstands common industrial cleaning chemicals, sanitizing agents, biocides, disinfectants and cleaning solutions.

The BW1 filter provides the industry’s highest level of cleanliness and lowest extractables. Constructed of non fiber-releasing, biologically inert materials, it is fabricated without use of binders, adhesives, plasticizers or surfactants. The BW1 filter is manufactured in a cleanroom.

The BW1 filter complies with FDA guidelines for food contact use. It also complies with USP Class VI Plastics Tests used for determining biocompatibility of materials.
