Question normal

Since CDC now recommends the use of homemade face masks (cloth as an option) for healthy individuals, most of the information I find suggests that these are not efficient taking into consideration that respiratory droplets can still go through cloth. The articles that CDC is basing these recommendations on are mostly case reports and focus on the fact there are asymptomatic carriers of the disease, not on the fact if cloth is actually effective in stopping these droplets. Any thoughts?
