MELO Air Review
MELO Labs takes a functional approach to nicotine-free vaping, offering devices infused with either caffeine or melatonin alongside flavored air options. The brand operates under the MELO and HELO sub-brands — MELO for sleep-focused melatonin diffusers, and HELO for energy-boosting caffeine diffusers.
Their ingredient philosophy is simple: vegetable glycerine from coconut and soybean oil, the active functional ingredient (caffeine from coffee beans or melatonin), and organic fruit extract flavoring. Everything is vegan-friendly and nicotine-free. The MELO Plus melatonin diffuser delivers approximately 800 puffs per device across eight available flavors.
MELO Labs also sells sleep gummies, showing they’re building a broader wellness brand beyond just vaping. Their products are available on their website, Amazon, and at Walmart. The functional ingredient angle sets them apart, though real-world effectiveness of inhaled melatonin and caffeine remains a topic of debate.

✅ What We Like
- Unique functional ingredient approach (caffeine and melatonin)
- Simple, clean ingredient lists — only 3 ingredients per device
- Wide range of organic fruit flavors (8 options)
- Available at major retailers including Amazon and Walmart
- Expanding beyond vapes into gummies shows brand commitment
❌ What Could Improve
- Effectiveness of inhaled melatonin/caffeine is still debated
- Only ~800 puffs per device — lower than many competitors
- Mixed customer reviews on flavor intensity
- Less established brand compared to competitors
MELO Air is an interesting player in the nicotine-free space thanks to their functional ingredient angle. If the idea of a melatonin-infused sleep diffuser or a caffeine vape that replaces your afternoon coffee appeals to you, they’re worth trying. The flavors are pleasant and the ingredient lists are admirably short. However, the science on inhaling melatonin and caffeine is still emerging, and the ~800 puff capacity feels low compared to brands like ARRØ or Cyclone Pods. For pure flavor enjoyment, other brands may offer more bang for your buck — but for the functional wellness niche, MELO has carved out a unique space.
