Went grocery yesterday, 2 places. I keep 2 masks in the car. HDX (homedepot) and 3M. Been using them since late feb or early march. Not a lot of use since I work from home.
Have found: HDX becomes clogged lot earlier. Not from dust, but I think moisture in the breath. HDX also makes my glasses more foggy. HDX is cheaper but may not be a good value.
