PAX Mouthpiece

My PAX makes a rattling noise when I shake it. Is that normal? +

There are two components in PAX that will make a bit of noise.

The mouthpiece has a small, sliding ring on the metal stem. This piece needs to freely shake back and forth for the mouthpiece to open and close properly - keep this clean to prevent your mouthpiece from getting jammed with build-up.

The other part you'll hear is the internal accelerometer, a loose ball bearing with sensors around it that detects the motion of PAX. When you shake the device to check the battery level, you'll hear the accelerometer making a slight clicking noise.

My mouthpiece won’t stay closed. +

The mouthpiece sits on top of a spring and as you push down about half-way, a clasp grabs the metal ring that sits just under the plastic mouthpiece.

If you’re having trouble keeping the mouthpiece in the off position, there’s a good chance you’re pushing down too far and missing the clasp, causing the spring to bottom out and pop up the mouthpiece.

Try this: Slowly press down on the mouthpiece until the clasp grabs the sliding ring, about half way down. Then gently release your finger or thumb.

Listen for this: If you hold PAX up to your ear when closing the mouthpiece, you’ll hear a slight click when the clasp catches the sliding ring. If you hear two clicks, it means you’ve gone past the clasp. After you’ve become familiar with the motion, you’ll be able to close the mouthpiece quickly and easily.

My mouthpiece is moving slow or is stuck in the closed position. +

There are a few reasons a mouthpiece becomes sticky or stuck in the closed position, but only you can prevent a stuck mouthpiece.

Reason #1: Buildup on the mouthpiece metal stem and sliding ring.

Overtime, residue will build up on the outside and inside of the metal mouthpiece stem and can begin to cause your mouthpiece to move slow or sluggishly. Unless you regularly maintain your PAX by soaking the mouthpiece and applying mouthpiece lubricant, this will get more severe and your mouthpiece could eventually become jammed in place.

The sliding ring that sits underneath the mouthpiece plastic helps latch your mouthpiece in the OFF position. It’s important to keep this piece clean so that it moves freely or your device may need servicing to remove the mouthpiece.

Try this: The best way to remove a sticky mouthpiece is to gently warm up the residue that's preventing the mouthpiece from releasing. You can try blowing warm air into the top of the closed mouthpiece, leave your PAX in the sun or in your pocket and let body heat do the work for you. Press the mouthpiece down slowly but firmly, wiggling it back and forth, until it slowly pushes itself back out. If you are able to remove your mouthpiece (whew!), clean and lubricate your mouthpiece before reinserting it into PAX. Check out our related FAQ’s below.

Reason #2: Disassembling the mouthpiece.

PAX asks that you never disassemble your mouthpiece. If you have disassembled your mouthpiece at any point and it is stuck in the off position, it will need to be sent to the PAX Pros for service.

Do not try this: Put down the pliers! Please do not ever use any tools to try and remove your mouthpiece as this may cause permanent damage to your PAX, and is not covered under the warranty.

If you are unable to remove a stuck mouthpiece contact the PAX Pros using our Support Request form.

PAX Cleaning Guide

I have to push my mouthpiece in slightly for PAX to heat up. +

Are you seeing a temperature color on the LED (yellow, orange, or red) when this occurs? It sounds like the internal sensor inside PAX is having a bit of trouble detecting the mouthpiece as being in the “on” position and is telling your PAX to stop heating, just in case you’re cleaning your device!

PAX’s mouthpiece lubricant is the answer. The lubricant cleans the internal sensor and helps prevent build-up. The lubricant should be applied after each cleaning when it gets wiped away. Before contacting PAX Support, apply mouthpiece lubricant per our instructions. You should be back to plooming in no time! If you still have trouble, please send us a Support Request.

What is the mouthpiece lubricant and how do I use it? +

Mouthpiece Lubricant should be a part of your regular maintenance. Applying PAX’s food-grade, water-soluble lubricant to your mouthpiece after cleaning (or even in between cleanings) prevents buildup from accumulating and ensures smooth mouthpiece action every time. Lubricant also keeps the internal sensor that detects whether or not the mouthpiece is in the ON/OFF position free of buildup.

Selected by the same engineers who designed the device, lubricant helps protect and prolong the life of your investment and makes future cleanings a breeze.

My mouthpiece seems to get hot when drawing on PAX. +

Even though your oven is hot, the mouthpiece is not. The mouthpiece for PAX, made from surgical-grade, high-heat-resistant plastic, does not really increase in temperature, at least not to any point that is noticeable by touch. Any heat you may experience is from the vapor you’re pulling directly from the oven. You can minimize the amount of heat coming in contact with your lips through a few minor adjustments:

Try this:

  • Place your lips over the opening of the mouthpiece and not in the opening.

  • Draw from PAX slowly. “Sip it, don’t rip it!” A gentle 2- to 3-second gentle draw before inhaling is sufficient to clear all the vapor in the oven chamber.

Can I soak my mouthpiece? +

The PAX Pros recommend soaking your mouthpiece (and your screen too) as part of your regular cleaning routine.

  • Throw the mouthpiece and screen in a container of Isopropyl Alcohol or warm soapy water while you clean the rest of your PAX.

  • Or soak the mouthpiece and screen at least overnight, at least once a month.

  • Rinse with water and dry both off.

  • Reinsert the screen.

  • Apply lubricant to the mouthpiece per instructions and click a few times to distribute.

About PAX mouthpiece lubricant +

Most PAX features are controlled by the mouthpiece, so you’ll definitely want to keep this component primed. By routinely applying the mouthpiece lubricant after your regular cleanings (and in between cleanings too), you’ll be reducing residue before it has a chance to accumulate and create issues.

How to apply lubricant:

A little goes a long way! Simply brush a drop’s worth on the exterior of the mouthpiece’s metal stem, near the sliding ring, and make sure to use the applicator brush in the interior of the of the metal mouthpiece stem. Reinsert the mouthpiece into PAX, click 10+ times to disperse the lubricant, and you’re good to go!
