Durable. run them 24/7

Fit was perfect, obviously because they are original replacement filters. Of course a lower price would be better, but I am getting my money's worth: I have 3 GCZ machines and run them 24/7

The filter is pricey, but I've had other air purifiers in the past and this is the easiest filter to change!
