I'm a longtime Filtrete customer, and have never been disappointed! I normally change my filters every 3 months, and when I remove the used filter, the dust particles are evenly distributed over the entire filter, not just in the center the way it used to be when I used the cheaper filters. Not only will you immediately see that there is less dust on the floors, but the quality of the air inside the house is so much cleaner. The filters may cost a bit more, but the difference is well worth it!
