Hi, the filters are not 4 inches. I will try and send pictures It's over 30 days but I didn't need to replace until now. How do I return or exchange?

I have used these filters for many years now and when inspected by professionals the comments are no extra cleaning necessary. Works for me!

Returning filters is a nightmare

Incredibly expensive to ship back. Do not recommend. Buy your filters local when you can. Mistakes happen. Company is incredibly inflexible.

The sizes are asinine. Just make them the actual sizes like some of the other brands

filter is a loose fit in my heat pump, i expected them to fit like the Honeywell that the unit came with but your filters are somewhat smaller and the fit in the unit isnt as tight as with the more costly Honeywell. Im hoping the function is okay but one has to be careful to install the filter otherwise it slips out of position. not that impressed by your product, bought 4 so in a year I will re-evaluate your product to see if re-order or new supplier is better.
