It is one of the best filters for painting and for passing liquid polyester with a strong smell, the most important thing is the expiration date of the mask to have at least months up to a year expiration date. If the expiration date has passed or if we have exceeded the painting hours (always with pre-filters on the filters, let's not forget), how do we understand is when we have new pre-filters and you continue to have difficulty breathing, then you should change them immediately.

It retains all the volatile substances I come into contact with, such as chlorine, aldehydes, alcohols, and it doesn't smell anything inside the mask with this filter
