3D Mask for Singers (5 count)

This disposable*, Canadian-made 3D mask for singers is surgical quality (ASTM Level 3 certified), packs flat with enhanced fit, and is comfortable, easy to breathe and sing through, and latex-free.

Its 3-layer construction includes a melt-blown polypropylene filter layer, but -- most importantly for singers -- is its very high filtration performance, ≥98%, with 3D shape (despite packing flat!) for enhanced volume and filtration surface area. And it is extremely light and comfortable to wear, with negligible impact on sound production.
One size (medium-large) available.

*Though labelled disposable, they're robust and capable of many wearings (but not washing) if you choose.
