N95s are, IMHO, way comfier to wear than cloth masks and surgical masks, and right now you can score 20 of them for just 89 cents each on Amazon. Since, you know, the pandemic is still happening and all.
3M Personal Protective Equipment N95 masks, $17.85
These N95s have at least 95% filtration against certain non-oil-based particles, and the noseclip is great for contouring them specifically to your face — and reducing annoying eyeglasses fog. Unfortunately, they're not available in kids' sizes (N95s are adult-only), but at this price point, we say stock up for the adults in the household. Plus, once masks are no longer something needed in society, you can promptly put them to work in your garage, workshop, or when you get elbow-deep in some grungy spring cleaning. Shop them now on Amazon while they're still in stock.
