Ahlstrom-Munksjö is partnering with Spanish sports and lifestyle accessories company Buff to provide its replaceable filter media for face masks.

Each Buff face mask includes five single-use filters in the original packaging. Replacement filters are sold separately in packs of 30 units. The filter mask is lightweight, ergonomic and easily adjustable and can be worn during sport and outdoor activities.

The Buff face masks, which were launched in Europe in June, are now available in the US and Canada.

“We joined forces with Buff on an exciting journey with a shared goal: helping to keep people safe,” said Laia Guarro, vice president at Ahlstrom-Munksjö’s Liquid Technologies business. “The expertise both companies have in their respective fields led to the development of this innovative product.”
