I did buy this a few months ago because I like to have them on hand when needed. I buy this even though the guy who worked on my furnace and replaced the blower motor said not to use these filters. He said they were the cause of the blower motor going out, because they would have to work to hard and need replaced. But these filters, I believe, do what they are suppose to. I have dog's and these filters help me breath better when the air conditioner for summer or heater for winter.
[This review was collected as part of a promotion.] We have been using this brand of for 14 years, it really works for my wife and daughters who have seasonal allergies. We trust Filtrete filters.
We've been using Filtrete Ultra Allergen Healthy Living filters for the past three and a half years. They keep our house literally dust free and fresh. We have two cats as well and appreciate the advantage of having good filters in our furnace that we change every three months.
