Good Simple Filter
Your review: These filters get the job done; protect HVAC equipment and filter larger dust particles. The more expensive filters that claim to keep your house cleaner really don't. To do that, they would need to essentially run all day, which you don't want for your HVAC.
Pros: Fit in the return duct nice and tight. At times, I simply vacuum them clean rather than replace.
Cons: None I know of
