Customer Reviews

Same replacement filter but requires work
Great for saving money but takes 10-15 minutes to set up properly since you have to remove the old clips and install this new filter. Since I'm dumb, it took me 35 minutes because I didn't fan it correctly the first time. You have to space each fold of the accordian design into each spacer correctly and not skip any. It has a learning curve and will be easier next time. There is an easier product that has the frame alreay built but it's more expensive. Also, there is a permanent model that you can wash but I couldn't find it on Amazon since buying my new furnace summer 2008 and needing the replacement Spring 2009. The washable permanent model would definitely be my cup of tea if I can find it again. But this is your cheapest alternative for the time being, if you require a #401 MERV 10 filter.
