Review on 🌬️ Optimal Air Filtration: Nordic Pure 20X25X5HM13 C 1 Replacement Filter by Jimmy Jefferson

I keep buying these because they eliminate pollen and dust allergens and also eliminate the smell of smoke in the air. We live in rural wheat country in Washington state. During the fall wheat harvest, forage harvesters fill the air with chopped wheat dust, and simultaneous wildfires in Canada and other western states make the air very unhealthy. These filters make the air in our room air conditioner breathable and very well tolerated, I would definitely recommend them.
