WoodyKnows Allerscreen Nasal Filters, Model 2024, Seasonal and dust Allergies aid (L, 3 Nasal Filters+12 Replacements)

Can't breathe through the mesh! I tried it in my mouth and hardly got a squeak of air past the mesh from either direction.. so if you think these are well sealed and are working well ...they're not ! You just have a leak !

Utterly useless. Uncomfortable and don't have any effect on hay fever symptoms, except making it harder to wipe your nose.

I've had hayfever for many years now. Every year, we'll cut back the tree in our garden, and every year the tree pollen has me sneezing and bunged up for hours afterwards. This year, I had these. I didn't find them comfortable to wear, but then again I'm not a big fan of having things up my nose at the best of times. Breathing through your nose is obviously more difficult, an I did find myself breathing more through my mouth while wearing them. They did however work. On cutting back the tree this year, I didn't sneeze once.Being small, I found them a little difficult to manipulate with my sausage fingers, but once I got the gist, I was able to do it to an acceptable standard.
