About Casey Nguyen

Casey Nguyen is a home appliance test engineer and reviewer who measures air quality and cleaning performance for a living. At The Fred Store, Casey covers air purifier reviews, robot vacuum reviews, and the ongoing costs — filters, maintenance, replacement parts — that most spec sheets leave out entirely.

Casey's background is in mechanical and environmental testing, and it shows in how reviews get written: a particle counter and a decibel meter come out before any opinion gets formed. That background covers filters and maintenance, room-size matching, and the noise-versus-effectiveness tradeoffs most marketing copy glosses over.

Every article Casey publishes on The Fred Store comes from equipment actually running in a real home, not a lab demo. Whether you're sizing your first purifier or trying to figure out why your robot vacuum keeps getting stuck, the goal is the same: numbers you can actually use.
