This filter is the perfect match for our Goodman furnace. It does a great job filtering dust and fine particles, and lasts up to 3 months.

Very high-end furnace filter. When it is on-sale (35% off) I like the value allot. That's why I bought it

I have been using this quality product for many years. It has become much more pricey in the last few years even with the discount so I am looking for alternatives.
