This is one of the 4 inch thick ones, so they are 25 a piece! Used to change my 1/2 think ones spring and fall.Those I'm more diligent about changing. We run our AC 6-7 months here so I change them out every 30 days. I just had a new unit installed last year so it's cheap insurance for keeping the coils clean. You're right those get dirty fast which is surprising since the windows are closed and we have no pets. With all that's going on in life I now set a recurring monthly reminder on my phone so I don't forget.
