Review on 🌬️ Furnace Replenishment for Allergen Bacteria - Filtrete by Bob Kussmaul

I have used these filters for six months in two returns. They collect almost all the dust in my house. I am very pleased with their ability to remove particles from the air, keep my evaporator coils clean and give my family clean air to breathe. I use the app and pay close attention to what my filters look like. I find the app gives a reasonable indication of the remaining filter life. The My Nest thermostat will also send a notification when it's time to change the return filters. I've found that the notification occurs around the same time as the app indicates the filter's lifespan is shortening (not a strict 90 day calendar) and depends on system requirements. The picture shows the new filter and the one to be replaced. We don't smoke; This is how well the product cleans the air. I am satisfied with this product and I recommend it to you too.
