I second this--anything but true laboratory testing is going to be unreliable. But to answer your question--any heavy carbon purifier with potassium iodide or potassium permanganate creates a chemical reaction which converts formaldehyde to other chemicals, which are harmless (to most people) or are

The issue with units from IQAir and Austin is that the amount of carbon makes it so they are pretty underpowered and you’d need multiple units to clean a space efficiently. This review from House Fresh does a good job of explaining. You’d need like three of them for 700 sq ft. I don’t know what you

Ultimately it depends on the concentration of particulates in your studio. For this, you'd need an AQI monitor like PurpleAir (Classic Plus, Zen, or Flex models) or the AirGradient ONE. Having a very underpowered purifier means it cannot achieve meaningful steady-state reductions of particulates. In
