Febreeze Allergen Reducer is a spray made by Febreeze. It says it will reduce the effects of allergies, and when I went to stay at my parents' house with their 2 cats as well as my sisters' 2 dogs and cat, my mother in law bought a bottle for me. She had no idea whether or not it would do anything, but I needed all the help I could get.
I wasn't there for very long when my eyes had started to itch and my nose was getting very stuffed up and my asthma was starting to really make itself known. My husband reminded me of the bottle his mom had purchased. I got it out and sprayed it around the living room where I was sitting and I noticed a difference almost immediately. There is a slight scent - kind of flowery, but mostly just clean. It isn't overpowering at all, which was a very good thing since I'm also allergic to strong scents. The air just felt cleaner and easier to breathe. I started to be less stuffy and my itchy eyes lessened. It was a few hours before I started to notice the allergies coming back and then I just did another quick spray and I was good to go again. I even sprayed the dogs and cats so that they could come near me without setting me off in a full allergy attack.
I never visit my sisters or parents without this spray. I love it and would highly recommend it to anyone with allergies.
