The Kelvin is a sleek wall panel that, like a sauna, uses far infrared heat. Used as a healing therapeutic, far infrared heat warms you and objects in the room gently, rather than using convection heat, which warms up the air first. It also doesn’t blow dust around, and is energy efficient. It’s aesthetically pleasing (also comes in white) and means there’s no risk of tipping over a floor heater. Confirmed via email this contains no Prop 65 chemicals including Teflon. 15% off with code INTERIORMEDICINE.
Blueair Air Purifier-Heater Combo
Blueair’s air purifiers are effective, transparent about test results, and more affordable than many. I’m happy to see they offer 3-in-1 air machines that cool, heat, and purify. They offer two sizes, one for smaller rooms and one for larger rooms, and two colors— black and white. Instead of alerting you to change the filter on a set schedule like many machines, it keeps track of pollution levels over time and reminds you through the app, which is a smart bonus.

FYI, “non-toxic” has no official definition, so I rate every product with the same method. It’s built on third-party certifications and published test data, not brand claims. For a deeper dive, my free course walks you through it.
