About Wellness Tools
In this section you'll find honest, evidence-first guides to wellness devices. We focus on what works, where the evidence is thin, and how to use these tools safely. Start with the guides below, which are interlinked so you can move from the science to device selection.
This category looks at the devices and tools people use to support their health, with a focus on what the research really shows. That includes red light therapy (photobiomodulation) — how it works, what it genuinely helps with, and how at-home devices compare to clinical ones — and air purifiers, including the CADR/room-size math, what HEPA filtration can and can't do, and honest reviews of specific models. The aim is straight talk, not hype.
