After 35 years, I finally found a good furnace filter at this off-usual size (30x36x1). Thank you, FilterBuy.

I bought these to have for my next filter change. I was glad to find slighter increment sizes to fit my old kenmore electronic air cleaner better.

Yellow is an unfortunate color

Stock images on the website conveyed a white color for the filter. Went back and reviewed what I bought and would have had difficulty discerning that the product is in fact yellow. Yellow doesnt look great. Also, the service filter indicator is now on our thermostat. Never seen it on before, only happened after installing this filter.
