Do you have this now? If you do, you better use it whenever you are going out even for few minutes. This N95 mask has been sold out in most pharmacies and I myself are still searching to buy this to protect my family members and I from the worsen haze here in Klang Valley. If you still can't find this mask, you can always use any surgical masks or a damp cloth.
How effective is this mask? Check out from other websites to find out more.
