It is important to buy mask filters that are made of 5-layers, high quality, highly breathable, and lightweight to use in between the layers of your face mask.
Luckily, you don't have to spend a fortune on face mask filters, as we do offer it at affordable prices.
PM 2.5 activated carbon (also known as activated charcoal) filter blocks up to 95% of airborne particles — everything from germs and dust to chemicals and pollen — thanks to several strong layers, including a high-efficiency filter cloth and an anti-stick cloth. So, a 5-layer filter will be very effective in preventing us from inhaling small droplets in the air we breathe.
Of course, filters and face masks aren't the only way to protect yourself and others against coronavirus, but they sure can help.
