Last summer we swapped out the regular HEPA14 filters in our purifiers for HEPA14 filters made to handle wildfire smoke with increased carbon filtration and a finer pre-filter for easier cleaning. I cleaned the filters every 90 days or so before replacing them at the end of the season and each time I took them out there had a dark grey layer of soot across the pre-filter mesh.
I don't think you understood the plan. I'm would increasing the hole in the door by 3 times and install a larger louver panel on the outside. On the inside I would add a filter holder system to hold the filters against the door. Then, as I said, I would need to seal the door frame because the door now has the filtering and any leaks in the door seal allow unfiltered air to the furnace. Or, maybe you weren't responding to me.
I defiinitely do not understand the plan. What is the benefit of adding a filter to the louvers?I don't think you understood the plan.

Yep. 16 x 25 x 1 is what it says on the packaging.
Will you recommend it to us? We have a Winix from Costco last year that we used in the 280sf room we spend most of our time in. We've just moved it to the bedroom instead of a tiny one and DW, who is the one that wants air purification, likes it in both places. Costco has a different, cylindrical Winix this year but I just ordered an Ecoself from Amazon ... great reviews, costs 60% less, supposedly good for 1500 sf so I hope it's not noisy, and it has 7 colors of lights, whoop de do!

We bought the Dayette brand products off Amazon and have been extremely pleased with both the purifier and the filter replacements.

@Time2 I don't understand either, and I'm not sure you do, and there is a potentially fatal condition here.I don't think you understood the plan.

It depends. Mine is built to take the thicker filters and when I use the cheap, thin ones, the air suction bends them in half. The thicker ones stay flat.
Ours is 20x25x4 Merv 11. I change it twice a year, just before we leave for the summer and just after we return in the fall. I buy them on Amazon, usually 2 to 4 at a time.
I stopped running a filter. We don't run our system but only when needed, and open the windows as often as we can...so I'm not sure the filtering buys us much. I get the ducts cleaned instead every couple years now.
Lost track of this thread. My thinking is same as yours but I was trying to avoid making assumptions without details.
Not a good idea - you really should have a filter in there at all times.
Even a cheap filter will save your furnace motor. I just have to look at my 1" filter which is only rated as an 8 , to see a lot of dust, hair, and stuff trapped by it, to know it is saving my motor, and making sure my furnace is blowing out cleaner air.
