is the only filter I can use on my AC so I can't compare. Seems a bit pricey though and I'm not sure my house is less dusty than it was before the new air conditioner with this quality filter. It's easy to see that this is a more complex, much larger filter, so I think that's why it's so expensive. I'm saving about $30 compared to my HVAC company we contracted for 2 visits a year. They call it fees to me so I was happy to find it. $11,000 per unit, the largest and newest model of the Infinity Carrier, released in 2006.
