Not quite time to replace my existing 6 month Honeywell filter yet but it is back to 4+"(unlike my Honeywell which went to 3") and also looks to be better "quality assembly" than my previous filter suppliers. They had issues with getting all the ends of the pleats glued to the sides.
I bought them for my father in law's A/C unit. He was paying a lot more money. The filters are a lot better quality and do a better job at keeping the A/C unit cleaner. Higher quality less cost filters.
