I've been using these filters for years and have virtually zero dust to speak of. The individual bags they come in are easy to tear open straight across the top so you can slide your used filter into it (avoiding getting dust all over the place).
Don't get suckered into thinking the more expensive, higher MPR-rating filters are the way to go, unless you know you need them. I use the 300-rated filters and it's plenty for the vast majority of people. Higher rated filters will only reduce the efficiency of your heating and A/C systems and end up costing you more for the filters and in utility costs. A tip I was taught to improve your filter's MPR rating without impacting air flow is to give the filter a quick spray with Pam (or similar) each time you replace the filter. It will attract even more particles to the filter.
Oh, and the box these come in has a tear-off portion so that it serves as a dispenser for the filters - nice bonus feature! (as of 2014, this...
I have been buying the Filtrete 300 for more than 2 years. It is the "lower end" in the Filtrete line, but I always viewed it as a step above the cheaper fiber filters. It got the job done, and I was happy with it. Recently I bought a new pack of these and went to replace my old Filtrete 300 filter (the exact same model, only older). To my dismay, I noticed that the new filter had several thin spots in it, not unlike the less expensive fiber filters I prefer not to use. I bought the six pack, so I thought this could be a fluke and pulled out another - same thing. At this point I pulled out my old one for comparison. Well, not only was the newer one noticeably thinner, there were 3 fewer pleats in the filter. It doesn't take a genius to figure out that fewer pleats means less material (and thinner material at that). It is kind of like that "2 oz." candy package that suddenly became 1.74 oz. but costs the same - bad move 3M! I used to love these filters, but now they are no better than...
This filter does exactly what it is supposed to do and is a good value. The slot my filter goes into is a bit tighter than it should be and the last set of filters used to have carboard strapping that would get stuck on the ductwork. This doesn't have that and it fits perfectly - even though it is the same size as my old filters.
When I pull it out after three months it is dirty, so I assume it is doing its job. I haven't noticed any increase/decrease in my utility bills, so I don't think it is overly restrictive.
OK. That is about as much detail as I can give in a review of a paper filter.
