It's still unclear how much of a role aerosols play in spreading the coronavirus. If you want to err on the side of caution, here's what can help minimize your risks:
that come out when you breathe or speak and prevent them from getting into the air. Ideally, to take precautions against tiny, aerosolized microdroplets,"we should be masking everyone with better masks," says Abraar Karan, a physician at Harvard Medical School. But the N95 masks that effectively filter most aerosol particles are in short supply and uncomfortable to wear. Karan suggests well-fitting KN95 masks which have similar protection .
Each precaution adds another layer of safety from aerosolized particles, says Milton."Wearing a mask means you're putting less virus droplets into the air, sucking less out [of the air]. Keeping distances means there's less of it near you. And having good ventilation or air sanitation means what's in the air is getting removed. All of those things add up to giving you good protection.

Carrier launches air filter machine for schools and other settings to keep air clear of coronavirusCarrier is launching an air filter machine to be used in institutional settings such as school classrooms, libraries and gyms, to help keep the air clear of contaminants like the coronavirus. The heating, ventilating and air conditioning company, part of Carrier Global Corp. after it was spun off the former United Technologies Corp. in May, said the new unit, called the OptiClean 1500-cfm Dual-Mode Air Scrubber & Negative Air Machine, joins an existing OptiClean 500-cfm unit, which was launched in April for use in hospitals. The machine can be plugged into a standard wall outlet and uses a long-life HEPA filter to improve indoor air quality. Chris Nelson, head of Carrier's HVAC business, said the company is expecting the machine to help schools keep students and teachers safe as they prepare to reopen in the fall. The units are portable and take up just three square feet of floor space. Carrier shares were slightly lower premarket, but have gained 62% in the last three months, while the S&P 500 has gained 13%.
