Cloud Nurdz Guide: 100mL vs Salts vs Fumi Disposable, and Which Should You Get?
E-Liquid & Disposable Guide • November 2026
Quick answer: Cloud Nurdz comes three ways. Choose Cloud Nurdz 100mL (freebase, 0mg, 3mg or 6mg, 70VG/30PG) if you use a sub-ohm tank or a refillable device at higher wattage. Choose Cloud Nurdz Salts 30mL (25mg or 50mg, 50VG/50PG) if you use a refillable pod system. Choose the Fumi x Cloud Nurdz disposable (up to 55,000 puffs, 20mL, 50mg) if you don't want to refill anything at all.
What Is Cloud Nurdz?
Cloud Nurdz is a US-made e-liquid line known for fruit pairings with a candy finish. On our product pages, many flavors list a "Nerds Candy" note alongside two fruits, like Watermelon | Apple | Nerds Candy. Many flavors also come in an Iced version that adds a cooling finish.
The Cloud Nurdz e-liquids featured in this guide are listed as TFN (tobacco-free nicotine), and the brand describes its nicotine as synthetic. Cloud Nurdz also offers the Fumi x Cloud Nurdz disposable, a high-capacity device for people who don't want to refill anything.
The real question isn't which flavor is "best." It's which format fits the device you use. Picking the wrong one is an easy mistake to make.

Freebase 100mL vs Salts 30mL: What's the Difference?
Both bottles carry the same Cloud Nurdz flavor names, but they're built for different devices.
- Freebase (100mL) comes in low strengths (0mg, 3mg, 6mg) with more VG (70VG/30PG). Sub-ohm tanks produce a lot of vapor, so a lower nicotine strength is the norm there, and higher VG gives thicker clouds.
- Nicotine salts (30mL) come in higher strengths (25mg, 50mg) with a 50VG/50PG mix. Salts are designed for low-wattage pod systems, where you take smaller draws. Our product pages mark them not for use in sub-ohm devices.
Rule of thumb: match the e-liquid to your device first, then pick the flavor. If you use a pod system like the Vaporesso XROS, salts are the usual choice; we compare two popular pod systems in XROS 6 vs XROS 6 Mini: Which One Should You Buy?
One more difference is volume. A 100mL bottle holds more than three times as much e-liquid as a 30mL bottle, so compare prices on the product pages. Volume only helps if your device is made for freebase, though. Using e-liquid your device isn't built for can lead to harsh hits or shorter coil life; see When to Replace Your Vape Pod or Coil.
The Fumi x Cloud Nurdz Disposable
If you don't want to deal with bottles, pods or coils, the Fumi x Cloud Nurdz Disposable is the simplest option. It holds 20mL of e-liquid and is rated up to 55,000 puffs at 50mg.
Its flavor menu is separate from the bottled lineup, though a few names overlap. Options include Strawberry Kiwi, Pink Lemonade, Sour Watermelon, Mango Passion and Clear. Check the product page for what's in stock.
Puff ratings are estimates that assume short, steady draws, so real-world counts are usually lower. For what to look for in a disposable, read Disposable Vapes in 2026: Which Features Actually Matter?
Popular Cloud Nurdz Flavors to Start With
These four come in both 100mL and Salts 30mL, and each also has an Iced version.
See every flavor, including the Iced versions, in the Cloud Nurdz collection.
Iced or Regular?
The Iced versions keep the same fruit and candy profile and add a cooling finish on the exhale. If you like a crisp, cold hit, go Iced. If you want the fruit and candy to come through on their own, pick the regular version. Not sure? Try one of each in the same flavor.
