Senior editor Michael Calore likes their reusable masks, which come in two different sizes. You can use flexible measuring tape to measure from ear to ear across the bridge of your nose to find the best fit.
The masks are made from jersey cotton and have a pocket for holding a filter. Unlike some of other picks, which loop behind the ears, they tie around the head. That makes them a little harder to pop on and off, but more comfortable for extended wear. This might be a good pick if you need to wear your mask all day, every day.
