I used to buy HEPA filters from different manufacturers and throw them in the trash every 3 months. This is by far the best option. The filter is very well made with an aluminum frame and is washable. This is literally the only filter you will ever need to buy. After installing this filter I noticed a pretty significant improvement in airflow. I recommend this to anyone who is tired of spending money on something you just throw in the trash. This filter easily pays for itself in less than a year.
