“I was given a sample of the HeiQ Viroblock +Multi Hi-Tech washable mask. As a cardiologist, I am used to wearing masks, but this one felt different. The ultra-soft fabric is extremely comfortable to wear and breathability is outstanding. Knowing that the built in-filter is usually used for surgical masks, for me is the real game-changer. Well done HeiQ! "
