Great for filtration
These are some of the best filters for cleaning the air. They are so good that they get full of dirt quickly and impede airflow much sooner than other filters that don't scrub the air as well. The challenge I had is that because they are so good you have to change them about every 2-3 weeks because air flow reduces and makes you HVAC system work harder and they get noisy. If you get these, make sure you buy more so you can change them more regularly.

Don’t waste your money!
These aren’t good filters I bought the correct size same size I always buy, and they’re yellow so you can hardly see the dust collecting. And then they fall out of the slot like they don’t even fit snug I will not be buying these again again I do not recommend them.

Undersize
The 20x30 size filter does not fit properly and it allowed dirty air to bypass the filter and get into the air duct. It needs to be about 1/4 inch larger in length and width to fit like the other brands. Now I need to go up into the attic and clean the evaporator out. Horrible!
