Review on 🌬️ Brondell Horizon O2+ Air Purifier Replacement Filter - Four Stage Composite Filter with True HEPA and Granulated Carbon for Enhanced Filtration by Jasmine Leon

I won't go into detail as I'm not an air filtration professional. I can say that I have had eight air filters in total and the Brondell Horizon works. I say that from experience. My allergies are no longer a problem at home. Our dog also has severe seasonal allergies and has been fine since we got Brondell. These replacement filters are of the highest quality. They are compact but heavy and very thick, containing multiple stages for ultra clean air. I'm really happy with Brondell and their filters are the best. They are durable which makes them very valuable. I give them stars.
