Are there significant benefits to installing the 5" vs the 1".

The 5" filters make your wallet a lot lighter!

If you change your furnace filter regularly (monthly) go with an inexpensive pleated filter.

A 5" MERV 10 filter lasts a year in most homes and costs around $30. A MERV 16 is 4 times that much and will fill up faster since it traps super fine partical that pass right through a normal filter. Unless you have health issues that require living in a clean room a MERV 16 is overkill. Because of the larger surface area of a 5" filter they are less restrictive then the same MERV rated 1" filter.
