still looking for mask recommendations and/or helmet recommendations with forced air. I appreciate all the dietary changes but I've tried all that - I'm in my 8th year and trust me, tried almost everything the sun including going completely vegetarian for a year. The root of the issue is some of us are born with high IGE in our body and some aren't - take a look at it and you'll see the science behind allergies
N95 filters pollen, assuming you wear it right. Fit the metal clip tightly to the bridge of your nose. If you fail to do that, the mask is 100% useless. At the bottom of the mask, make sure it is snug against the underside of your chin. Since you are a cyclist, you should have good to excellent lung capacity and no difficulty breathing through the mask.
The obvious downside is that N95 is not currently available in most markets due to Covid-19.
