Review on 20x20x1 Reusable Furnace Filter for Home by Yung Kaelin

Just installed and tried out this washable K&N filter. So far the airflow seems to be good. I'm sure it gets worse as the filter absorbs more, but I'm more than able to clean it and have spares to use while it dries. It's very well made, just like the K&N filters we use in our cars. I will delete and review it in 10 days. I also chose to just use a small amount of Dawn dishwashing liquid in water in a spray bottle as a cleaner as I've read others are doing the same. I will write again after 10 days of use. I really hope it works. At this point, the air actually appears to be flowing through normally. Might upgrade to 5 stars if all ends well when I check it out. It also fits perfectly into our cold air rear wall. 20x20x1.
