PAX

The Flow, the PAX 4 and the Mini 2. Earlier models including the PAX 2, PAX 3, PAX Plus and the original Mini have been discontinued, though replacement parts for the PAX 2 and PAX 3 are still available.

The Flow is the flagship, with a stronger draw and an air path designed to resist clogging, at three hundred and fifty dollars. The PAX 4 is the mainstream option at two hundred and fifty. Both are dry herb only and share the same general shape.

The current lineup is dry herb only. Older dual use models existed but have been discontinued. If you want concentrate, look at a dedicated dab pen rather than trying to adapt a current PAX.

No. The PAX 2 and PAX 3 share most parts with each other, and the Flow and Mini 2 are a different generation entirely. Check which device you own before ordering screens, lids or mouthpieces.

The devices are built to last years, and the parts that fail are consumables rather than the unit itself. Screens clog, oven lids warp and mouthpieces crack. All three are inexpensive replacements that restore a device that felt like it was failing.

The PAX 4 for most people, because it sits in the middle on both price and capability. Choose the Mini 2 if pocket size matters more than session length, or the Flow if you want the strongest draw in the range.

Run a pipe cleaner through the vapor path while the oven is still warm, and use isopropyl alcohol on the mouthpiece and screen. Doing it every few sessions keeps it quick, where letting residue cool and harden turns it into a soak.

Conduction. The oven walls heat the material by contact rather than pushing hot air through it. That is why packing the oven evenly and not overfilling it matters more on a PAX than on a convection device.
