I always use Filtrete filters and love the amount of "stuff" it takes out of the air in my home. I live in a dusty area so it is important to use a quality filter. My only complaint is that the filters are a 1/8 to 1/4 too big for the opening and I always have to pry them in with a screwdriver. The result is the cardboard around the filter is wrinkled and bent by the time I get them in. And with 10 foot ceilings it is hard to stand on a ladder to push them into the opening. I am what most would call a senior citizen and soon I will have to hire someone to change the filters because they are so hard to get into the opening. I would recommend them with limitations.
