Nēbu vs Pura: two different ways to scent a home

This isn't a like-for-like comparison, and the page says so up front. Pura is a smart plug-in: small 10 ml vials, gently warmed, controlled over Wi-Fi. Nēbu diffusers are cold-air nebulizers: undiluted oil turned into a dry mist with pressurized air, no heat, from a refillable reservoir. Which one is right depends on how much space you're scenting.

The short answerFor a single bedroom or bathroom with app control and scent rotation, Pura is simple and starts at $34.99. For open-plan rooms or a whole home, Nēbu covers far more space: up to 800 sq ft from a $149 tabletop unit, or 3,000 sq ft through your HVAC for $299. Pura doesn't make an HVAC unit.

  • You'd rather refill a bottle than swap vials

Pura is the better fit if
