IQAirWhite KN95 Face Masks - Protection from PM2.5, PM10, Ultrafine Particles, HEPA Filter, Adjustable Earloops, German Made

Excellent masks. Best masks I have tried by far!A bit pricey, but you get what you pay for. These are Made in Germany and seem very well constructed.These can be worn both behind the ears, or behind the head which is a very nice feature.Comfortable and extremely breathable masks. Highly recommended.

The media could not be loaded. There is no nose bridge wire to adjust fit for tight seal— the fixed plastic nose ridge means that on a lower nose bridge or a very tall bridge, there is a huge gap that lets in even large particles of dust or ash. Instead of a foam ridge, it’s just a thin piece of fabric that operates as a loose curtain. The only way this would work is if your face shape is a complete match to the plastic form. It’s supposed to screen out PM2.5 particles, but absent any means to adjust or secure a seal, this is completely ineffective for intended function.

This is the best light weight mask I have ever worn. It fits great and filters as promised.

These masks are quality built and include a plastic frame to keep them from collapsing when you inhale, making them much easier to breath thru. Plus they have material along the edge that helps ensure a seal. But they are small, and I mean tiny. At 6'3" and 235 lbs., these do not fit my face, they won't cover both my nose and chin at the same time (and that's the large). My wife is 5' 1" and 105 lbs., and the large fits her perfectly. If they fit me, I'd use nothing else, but they gotta fit to work right. IQAir, let me know when you make an XL.

These are extremely comfortable masks and afford excellent protection.

The masks are very comfortable. Seal likely to the face. The added structure keeps the mask off your mouth.

The product is NOT returnable, so buyer BEWARE. The mask did not seal properly. And very expensive.

It seems to work well on smoke from wood stoves and fireplaces of my suicidal sociopath neighbors.I also like the straps, a much better design than most and almost good enough to form a seal.Not happy with the price but still a bargain.
