I am a severe hay fever sufferer. I have been using the particle filter with the allergy mask for a number of years now. I use the mask while travelling on my motorcycle and usually feel better when I am at the end of my journey than I was at the beginning. When the pollen levels get really high I wear the mask most of the time. It makes a very positive and easily discernible difference. I unreservedly recommend it to anyone suffering with pollen or pet allergy. I recommend it especially if you use a motorcycle or bicycle. Just keep the mask away from Velcro. In my opinion this filter should be subsidised by the NHS. Thanks Respro!
