The dry herb vaporizer market is increasingly crowded as cannabis consumers seek alternatives to smoking. Pax is one of the most well-known brands in the game, introducing its portable vape nearly 15 years ago. The company introduced its updated Flow last year. Now it’s back with what it calls its most powerful device yet: the Pax Four.

In a press release, Pax says the device targets consumers who want big clouds in a lightweight, portable package.
“Pax Four is all about power,” CEO Chris Ahern said in the release. He added that the device “delivers dense vapor, fast onset and real intensity” while maintaining the “flower-forward quality Pax is known for.”
GreenState had a chance to test drive the new Pax Four. Spoiler alert: the dry herb vape definitely delivers on its promises. Want to know more? Keep reading.
How the Pax Four works
The Pax Four works just like the rest of the company’s dry herb vapes. Load loose bud into the oven, replace the lid, and press the mouthpiece to power it on.
Unlike the Flow, which featured a new side-mounted oven, the Four returns to Pax’s usual bottom-loading oven, holding up to 0.3 grams of ground flower. To power on, press the mouthpiece down for two seconds. Shake the device to check battery life; more illuminated petals on the front indicate a fuller charge.
Once on, the Four will start warming automatically. Pink LEDs indicate the unit is heating. Quickly press the power button to toggle through each heat mode. Each preset corresponds to a color-coded LED “petal” on the device.
The device comes with four preset temperatures:
- Petal 1 (purple): 190°C/374°F
- Petal 2 (green): 200°C/392°F
- Petal 3 (yellow): 210°C/410°F
- Petal 4 (red): 220°C/428°F
Note that these are slightly higher than the Flow’s temperatures. The company explained that the higher temperatures are designed to produce denser vapor.
They also said that the Four’s redesigned hybrid heating system produces 50 percent more vapor and heats up faster than previous Pax dry herb devices. The device includes haptic-feedback controls that may benefit users with visual impairments.

Pax Four review: big rips, robust flavor
The GreenState team was excited to compare the Pax Four to the recently released Flow device. Company representatives said the new unit targets consumers who prioritize power and potency, while the Flow is targeted toward the cannabis connoisseur who desires richer flavor.
Inside the eco-friendly “plastic negative” packaging, you’ll find the Pax Four device, a multi-tool, three oven screens, a wire brush, a USB-C charging cable, and both flat and raised mouthpieces. The Four looks extremely similar to the Flow, except for the oven location. It also feels noticeably lighter than the Flow.
The Four takes nearly twice as long to heat up as the Flow. The tradeoff: nearly double the battery life.
The GreenState team compared the performance of the two devices, and, as the company promised, the Four delivers far larger clouds—particularly at higher temperature settings. On the lower temps, the two devices are fairly on par in terms of vapor production.

Pax says the Flow is optimal for flavor, but the GreenState team felt the Four offered better taste at higher settings. In our testing, it delivered some of the best flavor we’ve experienced from a dry herb vaporizer.
The vast majority of dry herb vaporizers cannot match combustion in flavor, resulting in a homogenized bouquet that eventually resembles burnt popcorn. Even the Flow underwhelmed the GreenState reviewers. However, the Pax Four had a surprisingly pleasant flavor—it just might become a regular part of our rotation.
Just like the Flow, the Four appears incompatible with concentrate adapters previously available for the Pax Three and the Pax Plus. Representatives for the company said it plans to share more details about this soon.
Pax Four: a welcome edition to the dry herb vaporizer world
Overall, the Pax Four is a marked improvement over the company’s previous flagship devices in terms of power. While it may lack some of the bells and whistles of competing dry herb vapes, the vapor production and flavor are enough to make up for anything it’s lacking.
At $250, the Four is middle-of-the-road in price. The Pax Mini runs $150 while the Flow is $350. If you’re considering purchasing a Pax, the Four is definitely the Goldilocks of the bunch.
