and a two pack is nice so you have a back-up on hand
We got a new furnace a couple years ago and were surprised how pricey these thicker filters are. Normally we shop for the cheapest price, and a two pack is nice so you have a back-up on hand. Nobody here is particularly sensitive to dust or pollen, etc. so I can't speak to how effective these filters would be in that case. But for value filters that will get you through 3 or 4 months, these are fine.
