Review on 🔘 High-Quality HPA300 Carbon Pre Filter Replacement (4 Pack) for Honeywell HPA300 HEPA Air Purifiers - USA Made by Michael Custodio

Well I was hoping that they would fit our Honeywell HPA300 series units as Honeywell cannot supply them. As you can see from the picture they are too short. I've seen others complain that they're too big and they really wouldn't have a problem trimming them. But too short means they clog the HEPA filters sooner. Update: Apparently I installed them incorrectly. operator error. Anyway, I ordered some expensive ones from Honeywell and found they were the same size. You just have to move them to the right position. However, these filters work perfectly. Actually I will order more. Sorry for the confusion.
