The Heavy Duty Smoke Pencil ONE is the tool Professional Energy Raters and Contractors use to identify drafts and air leaks in a home. This non-toxic smoke stick generates a small trail or large puff of smoke to help you identify drafts. Simply pull the trigger on the Smoke Pencil Pro near the area that you suspect a draft and see how the smoke moves to show air current or leakage. You Talked and We Listened We are constantly upgrading the Smoke Stick to make it the easiest, most hassle free way of detecting air leaks. Upgrades to the Smoke Pencil ONE include a more robust battery cover with improved configuration, a green LED light to make the smoke more visible, new trigger locking mechanism that makes it less likely to activate the trigger accidentally while it is stored, better visibility on the fill / empty tank windows to read the fluid level, higher quality tighter plugs on fill and empty tank, and new fog fluid with higher glycerin content for thicker vapor with less sputtering. You're in Control. You control the amount of smoke this Smoke Pencil generates by holding the finger trigger, even upside down (with included cone adapter tip)! The fog comes out of the top chimney to reveal any drafts or leaks in your home, automobile, or business. The new cone adapter also allows you to control the puff of vapor to a smaller stream of smoke, so you can pinpoint where an air leak or draft is coming from. Light up your Space. Find the leak even in dark spaces! The highly visible green light on the top of the Smoke Pencil ONE illuminates the area you are testing for easy air movement detection. Fluid Included. A 3 oz bottle of non-toxic smoke fluid made of sweet smelling water, glycol, and glycerin (similar to toy train smoke) is also included with the Smoke Pencil ONE and features a special filling tube for easy setup. Now with thicker vapor with less sputtering! Lasts 12-15 hours Does not use the dangerous and caustic acid or incineration based smoke that other smoke sticks often produce. Additional Features and Information Handheld Smoke Pencil ONE dimensions w/ cone adapter tip: 3” x 2" x 6" Only consumes batteries & fluid when trigger is pulled. Robust body frame that resists drops & damage. Used by energy raters, HVAC technicians, auto mechanics, photographers, window salesman, airplane technicians, hospital maintenance, & contractors. Locking trigger for easier toolbox storage. AA batteries required (not included). Review: Reliable and Affordable Smoke Pen for Airflow Testing - This smoke pen has been an incredibly useful tool for understanding air movement in my home, particularly for diagnosing radon mitigation effectiveness. It produces a steady, visible stream of smoke that makes it easy to track airflow patterns around vents, doors, and basement areas. The build quality is solid, and after months of use, it still performs just as well as when I first got it. It’s compact, easy to handle, and doesn’t create any mess or strong odors. Unlike DIY alternatives, this pen provides a controlled and consistent smoke output, making it much more reliable for precise testing. For the price, it’s an excellent value. Whether you're troubleshooting radon mitigation, HVAC efficiency, or general ventilation issues, this smoke pen is a must-have tool. Highly recommended for its durability, ease of use, and affordability! Review: Both Broken Within a Year - I purchased two in 2025 and they worked fine for our experiment, but unfortunately when I took them out to use again this year neither of them work. ## Features - The Smoke Pencil ONE is a professional handheld air leak detector used by energy raters, HVAC technicians, auto mechanics, and contractors to identify drafts and air leaks in a home, business, or automobile. - EASY FOGGING – You control the fog in the palm of your hand.

I cant attach a PDF here on this Q&A tool, but if you reach me by message I can send it to you. **Q: I want to test the air flow in a computer case. Does the smoke leave any residue that would damage electronics?** A: When glycerin is used the smoke created is not harmful to electronics in small amounts, but it does contain water molecules that can harm electronics if overexposed. There are smoke products that are used in the testing of smoke detectors that are extremely low or no residue as required by NFPA standards. Just google for smoke detector test smoke. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Reliable and Affordable Smoke Pen for Airflow Testing *by A***. on April 2, 2025* This smoke pen has been an incredibly useful tool for understanding air movement in my home, particularly for diagnosing radon mitigation effectiveness.

Difficult to secure plug in fill port, so leaks at times. Pump trigger is inconsistent, large puff at times and less at times. Strength of batteries may have some affect on amount of smoke. I may need to learn to work it. Product met my needs. ## Frequently Bought Together - Smoke Pencil ONE Air Leak Detection - Handheld Smoke Stick - Draft Detector Puffer Fog Pen Machine Kit - Arctic Hayes 333113 1 x Pen Kit with 3 Smoke Sticks, Test Slight Air-Movement, Gas Mandatory CO Spillage Checks of Boiler/Case Sills, Orange - Smoke Pencil ONE Air Leak Detection Hazer Field Kit - Handheld Smoke Stick Draft Detector Machine with Fog Juice for Detecting Leaks, Puffer Tool for HVAC Techs Energy Raters --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/387524399-one-air-leak-detection-handheld-smoke-stick-draft-detector-puffer](https://www.desertcart.pt/products/387524399-one-air-leak-detection-handheld-smoke-stick-draft-detector-puffer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-18*
