These filters are amazing can shop comfortable ly without my glasses steaming il

Very pleased.

Excellent quality filters and coupled with the masks gives you confidence whilst wearing them. We have five in various colours.

Problem with packaging

The two masks I purchased were so tightly packed that when I opened them with scissors I had cut the cord on BOTH masks. I therefore had to repair BOTH by stitching the cord back onto the masks before I could use them which was extremely irritating to say the least. I doubt if I will make another purchase

Helpful addition

Needed to complete protection

Excellent masks in every way

I have found my NAOA mask excellent in every way. Comfortable to wear, with adjustable ear loops and a wire to grip the nose and reduce condensation for spectacle wearers. I was mine by hand in hot water with detergent, rinse it, squeeze the water out by hand, tug it out flat and dry it on a radiator overnight. Pop in a new filter and it’s ready to use again. I’ve been using the same mask for six months and it still looks good (I have two more ready to go when needed). Oh, and I can wear it for four hours at a time at the food bank where I volunteer without a problem. “Keep Smiling” mine says. I do.
