These words might have compelled you to purchase your microfiber cloths to help in the fight against coronavirus
'capable of "trapping and removing" 99.9% of bacteria from hard surfaces'
the coronavirus is not a bacteria but a virus therefore anti-bacterial and/or anti-microbial microfiber cloths will not be what removes the coronavirus from your non-porous hard surfaces.
Soapy water and rigorous scrubbing will.
Using any of the Health Canada approved disinfectants will help against the fight against the coronavirus (Click here to find the natural and Eco-friendly ones)
Ensuring your dusting cloths are always damp (not dry) to trap the coronavirus and not spread it around will help.
Soaking all of the cloths you have used in soapy water for a time (I do overnight) will help
Anti-bacterial and/or Anti-Microbial microfiber cloths will not unless you use them in harmony with all of the steps above so why spend more to protect you and your loved ones when you already have what you need.
