You're right N95 is the best but since they are hard to find, KN95 masks which are on the FDA list are reasonable substitutes for non-medical use. The masks here are not on the FDA approved list.
I tried using N95s all day long and it's pretty brutal. A KN95 is tolerable.
Maybe those comparisons are not quite apples to apples - but I think it is important to make sure people realize that the amount of filtration on these masks is unknown and could be significantly lower than 95%, potentially as low as 1%. If you're comfortable with it potentially being no better than a surgical mask that might cost 0.30 each, then go for it - just trying to educate that many KN95s are not working as advertised, in some cases much worse - and it is important to know who the manufacturer is. Without knowing that, you could be buying an expensive surgical mask.

It has 5 layers protection too.
Why do you still think this is not great?
Also, can you share some better product links comparing this if you feel this is dangerous?

There are non-NIOSH masks that are acceptable for non-medical use. The major difference between the N95 NIOSH standard and standards from other countries like KN95 is that KN95 allows for some small amount of air leakage (8%) which allows the use of ear loops. NIOSH approved N95s are obviously the best but they are nearly impossible to get at a reasonable price since most N95 stock is being bought up by Government and Medical customers. There are KN95 masks which have met FDA approval and are effective although not as effective as a true N95 mask. You can see which ones are approved here: https://www.fda.gov/media/136663/download and some test results here: https://www.cdc.gov/niosh/npptl/r...sults.html

I'm not sure just being a good price is all that should matter - these masks should filter out 95% of particles and if it is not doing that - lets say it is only filtering 20%, is it a good deal still? Would you buy a laptop that was a good deal but only ran at 20% of the advertised speed, or a 65" TV where only 20% of the screen was functional?

Both masks listed in this post are ear loop KN95 which are garbage compared to headband loop style. The way it attaches to your face matters due to fact that ear loop style means it is not as fitted and more air can pass around it
There are KN95 masks while not as good as N95 - but do meet the 95% filter efficiency. They are on the FDA list I linked above. Here is an example of one, but they are much more expensive ... It probably depends whether you're at high risk or work in an environment that is high risk to say whether it is worth buying a higher quality mask or not: https://backtonormallif
