Filtrete Adv Allergen Reduction Filter

I purchased this filter about two or three weeks ago and I can tell that the filter has made a huge difference in comparison to the crummy blue filter that was previously in there. I live in the country where pollen is profuse and bountiful and originally I would sneeze a lot while indoors as well as feel like my sinuses were being attacked. Since I've bought this my sneezing has slowly come to a complete standstill and now is non-existent. I didn't think I'd notice that big of a difference but I can tell the air quality in my apartment is much better than it was originally. I say sport the extra money for quality (ergo 3M) and the added allergen protection has been fantastic.
