You believe it’s funny, I used to travel a long way to go to this particular hardware store that sold cheap HEPA air filters, and it was the main reason why I would go to this site because I always liked to stock up on those things. I believe that HEPA air filters are the best because they pull 99.9% of contaminants from the air. I can’t tell you how much they have helped myself and others with my flu symptoms plus it’s really a must. I actually used to use pleated air filters that are designed for people with flu symptoms, the thing is, they don’t labor entirely well or at least not as fantastic as HEPA air filters. When you have exhausting flu symptoms enjoy mine, trust me, you want to go for the best air filters available, however at my local stores, they only have cheaper types of air filters including the fiberglass 1s plus pleated, and none of them are that great, that’s why I always find myself driving out of the way to get the fantastic 1s. I remember talking with somebody about how I would always drive the distance to get my air filters, but then they asked myself and others why I didn’t purchase them online. I was surprised plus said I didn’t believe you could purchase air filters online. They responded by telling myself and others that you can buy just about anything online. I really couldn’t argue with that plus she advocated a fantastic site to buy HEPA air filters. I was blown away with the much lower price for these HEPA air filters when you obtained them online! Also you can get them in bulk for even cheaper!
