William, the pre-filters do work and they work very well. I change the pre filters regularly and when the app tells me to clean the inside screen there’s practically no dust to be found inside the blower unit. Cheers, Michael
Nice work very simple and functional. I just installed a three head Mr cool in my basement and now I have a road map for a great pre filter. Since you’ve had it in for a year how has it worked out?
John, it’s working excellent! Now when I get the regular app reminder to clean out the internal filters, there’s practically no dust inside the unit. I just regularly blow out the external filters and rotate in a new one every few months. And thanks for watching. Michael
Great question! I did some serious research into static pressure when designing my dust collection system. I unfortunately do not own or have access to the specialized tool required to measure SP inside the filter box. MRCOOL tech folks were OK with this setup and just reinforced regularly changing the filters. The filter box does work as designed. There is barely any sawdust inside the unit, which is regularly blown out with compressed air.
David, sorry you had trouble getting a hold of the folks at Mr Cool. It’s always been pretty straightforward for me by calling the customer service number at 270 -366-0457. They’ve always been very responsive to my calls.
Ed, the filters are working perfectly. I did add another box to hold two additional filters. So now I have four total. When I do the regular maintenance on the unit's own internal screen filters there is almost no dust to be found and my condensation drain line is still completely clear and clean. With space for four furnace filters I usually replace one each month and blow the other three off with compressed air. I highly recommend this type of pre-filter add-on if your split unit blower is in a dusty environment. Cheers and thanks for watching, Michael
I had the scraps laying around….seriously I was catching so much dust in the two filters that I wanted to minimize the possibly of stressing the bower with air restrictions so it just made sense. I now regularly replace one of the four filters and compressor air blow out the others.

I have had the exact same issue with dust build up in the condensate drain pan.

I am curious what the static pressure is inside the filter box when the fan speed is set to high.

Do you have any idea how I can get a replacement filter for the evaporator unit. The company won't even answer their phone.

How is it doing after a year of use?

@@SapperWoodworking What made you decide to increase to 4 filters?

@@SapperWoodworking What size filters for the four you increased it to? 16x25x1 x 4 ?
When I added the extra two filters I changed them all to x 4’s.
