Review on 🌬️ Ultimate Air Filtration: AIRx HEALTH 20X20X1 Pleated Filter for Enhanced Indoor Wellness by Aaron Collins

I've been buying these filters for a year and a half. I work in the HVAC industry so I know the importance of air filtration. I have 2 cats and a dog so I change the filter monthly. The quality of the merv 13 filters I received met my expectations. The problem is that Amazon is constantly changing suppliers. Now received a different batch than the others ordered and undoubtedly in the Merv rating the airflow through the filters is much less. This causes my return channel to be sucked and flexed much more than before, resulting in excessive noise. The temperature at the heat exchanger also increased significantly during the heating period. This could have been disastrous for my system if it had gone unnoticed for too long. Unfortunately I cannot recommend these filters to any of my clients as they do not know what they are actually getting.
