Review on 🌬️ Air Purifier Filter: 3-in-1 True HEPA for Pet Dander, Odor, Smoke & Dust in Home & Office by Kimberly Bourque

I am disappointed with this unit. It worked great when I first got it. After the first filter change, the displays no longer worked properly. I pressed reset and it turned blue, then green again a minute later. I ran it that way and about a week later the red dirty filter light came on. I changed the filter again and reset the settings and now the 'Filter Dirty' indicator doesn't go off at all even though it's a brand new filter. These filters are suitable for this machine. I feel like I wasted my money as it didn't even last a year. When I first got this, the light was green for a while but eventually turned blue.
