They ARE fast! I only paid for standard shipping, estimated arrival 4-6 days. For some places, that means the time it arrives at a regional shipping center and your items aren't actually delivered to you for a week. Not so with fast filters. My filter arrived three days later. I'm impressed. And I was a little skeptical since it was a replacement filter, not the name brand. Fits perfectly and works great!
