Was at my local Costco in Livermore, CA yesterday. They had the 20x30 3M air filter 3 pack for $30. Pretty good deal for $10 per filter. This is not sold online, so the online link is for reference only. Online only sells 4 pack.
Yeh there a chip in middle (covered by yellow plastic) with Bluetooth signal, you remove the tab to activate it. Its overall alright nothing to be excited about.

Might be a mistake? I got the regular 3 pack 3M filters few day ago for the same price. I had to check if the ones I got were smart. It is good deal for the smart filter.
4 okc online deal is not bad either. 11.25 as opposed to 10 per filter. As I recall store has only two sizes. 20x20 and 16x20. Online there are a lot more options. 9 different sizes available. IMO

They had other sizes. I can't remember the dimension. You can try calling first.
All the usual sizes that they carry in store. I only buy the 16x25x1 size, but there were at least 2 other sizes.
