This is not a sales pitch but a testimony. Since 2013 I have been using the Invisible Nose Mask Pit and I can confirm that from January 2014 to-date I have not had any Pollen Allergy Symptoms. I use the Nose Mask Pit on a daily basis, it's very comfortable and it was easy for me to get use to wearing it everyday. My reason for wearing it was because I spent 3 hrs each day travelling in the underground and also had a business in the underground. But as a solution to the air I breathe, I found our that the Nose Mask Pit is perfect for my Allergy and I have never stopped using it. Their is no drug associated with the product, so natural in design.
If you want a solution for this allergy season, it is worth given this a try, but you have to use is regularly and can be used during pregnancy. iokidoki.com
