They fit well, and work well. I love that they are made in the USA. I also like the reminders that it’s time I change and receiving them in the mail.

White filter

I wish the filter was still white. I know it is probably easier for you guys to color code them but where theses are used are up high and you can see the color of the filter. I would prefer white.
