Boldr Kelvin

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.

Objecto Foot Heater

If you suffer from cold feet, this is the best solution. I use this sleek foot heater every day when I’m working on Interior Medicine’s website and answering emails. It works for both standing and sitting, keeping me active, and doesn’t blow dust around, keeping me from sneezing. Confirmed via email this contains no Prop 65 chemicals including Teflon.

Blueair Air Purifier-Heater Combo

It’s no secret that I like Blueair’s air purifiers— they’re 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” doesn’t have a definition, and I use the words chemical-free,toxin, and toxic on Interior Medicine inaccurately. I do this for practical purposes, for now: they’re accessible terms that allow people to find what they’re looking for, and they’re shorthand for a complicated problem. I made an entire (free!) course about this. Check it out here.
