Not too many pleats
on June 26, 2026
Posted by: Customer
This filter that I purchased to use in my Carrier Infinity HVAC system does not have many pleats, maybe 10-12. The original Carrier OEM filter has about 100 pleats which I assume would catch more dust and debris. The price of the Filterbuy unit is about 1/3 the cost so I'll see how well it performs before I make a decision to buying one again.

I am very happy with my filters. I needed an unusual size. I previously had to buy 3 smaller ones and duct tape them together every 3 months. Your filters came quickly, damage free, and is a much better quality. It took less than 30 seconds to change out and I noticed a difference in my air quality that same day. I bought a year's supply, so I will definitely be buying again next year!
