I'm based in Hong Kong where its common for people to wear medical grade disposable face mask. But considering the damage that disposable face masks bring to natural habitat, I decided to give reusable face mask a try and purchased several from a small local brand Green Sisters. 

It's summer now and I was initially concerned about the mask breathability. Fortunately Green Sisters has a featherweight collection that uses thin fabric and has standard protection (99% BFE, 97% PFE, 95.9% VFE). I recommend to use this mask for work and casual hang outs in summer, and stick with disposable face mask for exercising. 

Here's the Green Sisters link if you are interested:
