The mask i used was much cheaper and I've done a lot of research to see if all these low-cost masks aren't as effective for the corona virus. so you can give me the details of a top level mask.
1. Name:
2. Price
3. Durability ( How long can i use it)
Surgical mask and N99 or N95 is recommended to use, but i just use a washable mask. It is a cotton or cloth face mask with a price of 1 dollar in the market.
