Jorge purchased a set of Cycling pack including a set of PRO filter and told us he has been using the F94 filters before. He bought the PRO filters as an upgrade to improve the protection.

Hello Francis:
6 weeks ago I started using PRO filter.  I noted more air flowed through the mask because I felt the air colder.
Please find attached some photos after changing the PRO filter with new ones.
Also, I changed fabric straps with rubber straps, I felt fabric straps too loose.
It is incredible how the PRO filters got dark on the outside but inside they are clean, that is proof they are making their job.
I did not find any disadvantage on PRO filter.
Regards,
Jorge
