“It's worth the upgrade. My house smelled better nearly instantly. Next time I'll upgrade to the 416+ to see if I can tell a difference for any of us due to the better allergen filtration.”
“These filters are more expensive than with my last furnace, and I have to change them about every 4-5 months based on the amount of dust I'm getting on furniture and carpet. They definitely don't last up to 12 months for this household. We have a pet free home and keep our windows closed the majority of the time due to allergies and humidity. I had high hopes with the updated system we put it, but this is costing me more.”
