This is a common misconception. The virus doesn’t arrive as individual viruses. If it were purely a matter of filtering 100nm particles, a n95 mask wouldn’t be very effective either - the ratings are for particles 0.3um or larger.
Luckily, people don’t generally sneeze out plumes of pure virus. They’re embedded in much larger particles, and even cotton has some benefit: https://smartairfilters.com/en/blog/coronavirus-pollution-masks-n95-surgical-mask/ https://smartairfilters.com/en/blog/coronavirus-pollution-ma...

What your cloth mask is doing is to effectively spread a giant fishing net to collect all the particles around you. The moisture in your breath will help keep the viruses inside intact. You'll be constantly breathing air through that, loosening some of those particles and inhaling them. The idea that the mask would protect you makes no sense. If you're already infected, it's a different story. The mask will reduce the amount of virus you'll be spreading around.
