Oil-filled radiator heaters are the safest choice for health. They don’t dry out the air as aggressively as fan-based heaters and carry no combustion risk at all. One important correction worth knowing upfront: electric heaters of any kind do not burn oxygen or reduce oxygen levels in a room; that’s a widespread myth.
