Can is ok, next time you reup, try a Phat or Phresh, they last way longer. Their antibypass tech is good too as many carbon filters dont use the bottom third of the filter as much as the top 2/3.I prefer Can brand filters, they were about the only ones out when I started doing this or and they still make great quality filters. I've never tried phat or phresh but compared to cheap Amazon ones or the active air ones Can brand is way better.
