We clean the filter regularly hygiene so that they would not be replaced with each bag change.
Since they are always supplied practically we throw actually still intact filter also with off (you could save money and waste if it were not so)
All in all, the bag processed stably even measured in an animal household with strong hair cats really big so every 6-8 weeks only, the bag needs to be replaced.
The only fly in the ointment of the relatively expensive price (you just pay the brand name on every item anew with) and the filter are always included and are part of a package.
Delivery from Amazon again top - as always.
