These filters seem to capture the same amount of dust as any other filter we've used. Cleaning can be difficult. We recommend vacuuming the filter before hosing down. The filter retains a lot of water and takes several hours to dry in the sun. Supporting with a 90 degree filter angle helps to drain the rinse water better. They're uncomfortably loud. Now the hissing can be heard constantly in the house. Maybe they are too restrictive? All of this is to say that it's good to have a durable product that isn't constantly being added to the non-recyclable waste stream.
