ONE Air Leak Detection - Handheld Smoke Stick - Draft Detector Puffer Fog Pen Machine Kit

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!

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.

Works fairly well. 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.

Works great for value. Close in value to smoke pens but better. Cheaply made but as I just noted a smoke pen costs about the same and this works a lot better so comparatively it is great. Well worth the price versus other options. I use smoke testers regularly for work and am happy with it even considering it might not last very long which is why I gave it five stars.

Bought 3 one worked great, one worked for a while then quit working then would start again, one never worked at all. Have bought these before and definitely not a long term investment product. Buy what you need for a job (with spares) and you'll be ok. Wouldn't plan on keeping them around for multiple jobs, or if you do test them in advance. Glad I bought 3 but didn't expect to only have 1.5...

It got the job done for one project, I won't be using it agian,but it was very cumbersome to work with and the quality wasn't great.

I got this to help identify drafts around windows, doors, walls…anything! It produces a white smoke which is easy to see with the green light it emits. It took a few tries to understand how to use it since directions were not the best. Lightly pull the button (not the pressure trigger thing) and it will begin to smoke. Pulling the trigger will create puffs or a lot of smoke at once but will also deplete the smoke so will momentarily need to create more. Overall it does exactly what I wanted it to for a fair price.

I have had two of these little black beauties. The first one I bought over five years ago. It only half way worked, with minimal - and I do mean minimal - smoke. I think I tossed it out sometime back. I needed another generator, so against my better judgement, I bought another one. It's the same problems. Little "whisps" of smoke, if any at all. It is not easy to fill and when doing so, it leaks the sticky oil all over. In my opinion, this unit is a cheap piece of junk from ... you know where.

Good Product

Waste of money

This unit work ok, but the reservoir leaks a little. Be sure to store it upright!!

I use it for work. Product worked perfectly and did the job I needed.

Used this for a job to visualize airflow. It works great it produces a large amount of thick mist to visualize air flow well with or without a flashlight aiming on the smoke. Threw it in a back pack and it turned on (even after using the lock on the trigger) and it overheated and melted out the filament. It’s just a poorly designed mechanism for triggering the heating element. There needs to be a way to store this like a tool. It can’t be so delicate. It’s essentially a large vape pen.
