Review on 🚲 Cycling Replacement Activated Filters-Swapping for Enhanced SEO by Steve Cooper

These filters are much better than the filter that came with mine Sport mask and the valve is much better than the filter valve that came with one of my masks. When I received the second mask the first thing I noticed was what I could see under the filter which is a straight unfiltered vent that breathes in and out therefore useless. The other hole closes on inhalation, pushing air through the filter, but opens on exhalation. However, the cloth masks I have complained about fog up my goggles, redirecting unfiltered air around my goggles and causing fogging, so what's the difference. Not to mention that unfiltered air exits the same way and unfiltered air enters the same way. A sports mask is also much cooler than cloth masks.
