I'm told that Lennox has discontinued their 20x26x5 filters, especially in the MERV 16 category. Can anyone confirm this?
The furnace is only about 10 years old and if this is the case I find it poor practice from Lennox to leave an installed base of customers stranded without proper sized filters.
