Doctor Merv — a friendly cloud-headed character in a Hawaiian shirt and white lab coat with a stethoscope
Our story

The idea

Air filters are about the most commoditized thing you can buy. A box on a shelf at the hardware store, thirty dollars, no relationship, no reminder, no idea whether it’s even the right one for your home. We thought that was a strange way to treat something you breathe through every day.

02

Why a doctor

So we gave the category a doctor. Doctor Merv turns a forgettable errand into something simpler: a clear read on your home’s air and a straight recommendation. He’s part coastal, part clinical — the Hawaiian shirt is the fresh-ocean-air promise, the lab coat and stethoscope are the part that’s actually tested and true.

03

What he stands for

Doctor Merv has one rule: say what we capture. Not “for pets.” Not “for allergies.” We tell you the particle, the size, and the MERV tier that catches it — sourced to EPA particle science and ASHRAE 52.2 capture testing. If a filter can’t capture what causes your problem, he’ll tell you that too.

“We’re not interested in the technicality. We care about the actual quality of your air.”
