Review on Colorfullife 2 Filter + 4 Carbon Booster Filters: High-Quality Replacement Filters for Holmes AER1 Type Total Air Filter, Compatible with HAPF30AT and HAP242-NUC by Melissa Davis

I received these 2 filters in a plastic bag with no maker or brand in the box. They look just like the OEM filters and come with a carbon seal. The price is much lower than OEM, so no complaints. You'll have to use them for a while to see how they actually filter the air. Since they look the same as the original materials, I would expect them to perform as well or even better due to the addition of the activated carbon filter.
