bring this too schoolsthey need to add this to schools the mask thing is absurd, there is a growing parents complaints about schools i pulled my own kids out of schools because its a mess,a big joke and not safe IMO. When all this started they said only N95 mask was effective now kids need to have plastic/paper mask all day long that arent effective they are probably only limiting saliva transmission while air quality isnt verfified now in term of investment imagine if you have 20k unit not sold sitting in boxes while our ppl get sick... Canada isnt USA we want ppl to be healthy the more healthy and safe they are the less they cost in taxes in USA the more ppl get sick the more money they make ..
