Review on 🌿 Maximize Air Quality with the Aprilaire 201 Replacement Filter Purifier by Carl Henderson

I have previously purchased an aftermarket filter rated MERV 13 but the reduced flow was causing an error code 33 in my oven which I have never seen before. The original Aprilaire 201 has an original MERV 10 rating and when I used it to replace the MERV 13 filter the error code went away and the oven worked properly again. Maybe a MERV 13 replacement will work in some ovens, but it will in my high-efficiency carrier. The reduction in airflow was too great. From now on I will continue to use the Aprilaire 201.
