SMOK Nord 5 Review

Mr Fog Switch allows you to choose between two flavors with a simple switch flip. Sounds cool, right? Yeah, I found it to be pretty amazing as well. But, when I first got my hands around it, I thought of how to use Mr Fog Switch exactly. 

Simply, take off the rubber cap. Locate the side switch indicating two flavor options. Slide the switch to your desired flavor. Inhale from the mouthpiece to automatically produce vapor (the device is draw-activated). When done vaping, put the rubber caps back on

Intrigued to know more about vaping Mr Fog Switch? I laid down a complete guide on this right below. Let’s get started!

How to Use Mr Fog Switch? – Proper Steps

Using the Mr Fog Switch is straightforward. You don’t need to charge, fill, or replace parts. All you need to do is follow these steps:

  1. Remove the Mr Fog Switch from its packaging. Take off the rubber caps from both ends of the device.
  1. Locate the switch on the side of the device. It has two positions, one for each flavor. You can see the flavor names on the switch and the mouthpiece.
  1. Slide the switch to the position of the flavor that you want to vape. You can switch between flavors anytime you want, as many times as you wish.
  1. Inhale from the mouthpiece. You don’t need to press any buttons or adjust any settings. The device is draw-activated. So, it will automatically produce vapor when you inhale.
  1. When done vaping, put the rubber caps back on the device. 

That’s it! You have successfully used the Mr Fog Switch. As you can see, it is very convenient to carry around. You can enjoy two flavors on one device without any hassle or waste. As reported in the Nairaland forum, the Mr Fog Switch can last for up to 5500 puffs. That’s equivalent to about 45 packs of cigarettes. So, you can use the Mr Fog Switch for several days.

Proper Inhaling Technique Of Mr Fog Switch

Want to get the best throat hit from your Mr Fog Switch? Well, there is no one right way to inhale the Mr Fog Switch. Different people have different preferences and styles. However, here are my techniques that you can follow:

  1. Start With Small And Gentle Puffs: This will help you prevent any coughing. You can gradually increase the length and intensity of your puffs as you get more comfortable.
  1. Don’t Inhale Too Hard Or Too Fast: The device might overheat and taste burnt. It will also waste your e-liquid and battery life. Instead, inhale slowly and steadily.
  1. Don’t Hold The Vapor In Your Lungs For Too Long: Exhale the vapor as soon as you feel satisfied. This trick will minimize the harm.
  1. Experiment With Different Inhaling Methods: As I learned from E-cigarette Direct, there are two main ways to inhale the Mr Fog Switch: mouth-to-lung (MTL) and direct-to-lung (DTL). You can try both methods and see which one suits you better:
  1. MTL is when you first draw the vapor into your mouth and inhale it into your lungs. It is more suitable for beginners and smokers. It mimics the motions of smoking. 
  1. DTL is when you inhale the vapor directly into your lungs without holding it in your mouth. Experienced vapers use it.

Mr Fog Switch Settings: How Do I Adjust The Airflow?

You can’t adjust the airflow on the Mr Fog Switch. The Mr Fog Switch has a fixed airflow. However, if you want to adjust 

Mr Fog Switch airflow settings, here are my tricks that you can try:

  1. Cover The Air Holes With Your Fingers: The Mr Fog Switch has two small air holes on each side of the device near the bottom. These are the places where the air enters the device when you inhale. 

Cover one or both of them with your fingers to reduce the airflow. The low flow of air will give you a stronger throat hit but less vapor. 

  1. Use A Rubber Band Or A Tape: Another way to cover the air holes is to use a rubber band or a tape. You can wrap it around the device, covering one or both air holes. 
  1. Inhale Faster Or Slower: Changing your inhaling speed is a more straightforward and safer way to adjust the airflow. If you inhale slower, you will decrease the airflow. The low airflow will give you a stronger throat hit but less vapor. 

How to Fix Mr Fog Switch? 

You will occasionally run into some problems with your Mr Fog Switch. Here are some troubleshooting tips for common issues:

1. Empty Device Fix – Refill A Mr Fog Switch

Mr Fog Switch is not officially refillable. To refill a Mr Fog Switch, you will need a syringe, a needle, and your preferred e-liquid. 

  • You will also need to remove the rubber caps from both ends of the device. 
  • Then, insert the needle into the mouthpiece and inject the e-liquid into the device. 
  • Do this for both flavors and ensure you do not overfill the device. 
  • Be careful not to puncture the battery or the switch.

2. Mr Fog Switch Not Recharging Fix 

This method is not officially endorsed but works with rechargeable and non-rechargeable Mr Fox Switch. To recharge a Mr Fog Switch, you will need a USB Type-C cable, a power source, and electrical tape. 

  • Remove the rubber cap from the bottom of the device. 
  • Then, cut the USB Type-C cable and expose the wires inside it. 
  • Connect the red wire to the battery’s positive terminal and the black wire to the negative terminal. 
  • Secure the wires with some electrical tape.
  • Plug the other end of the cable into the USB port of your phone’s power brick. Or, you can also connect the cable to your laptop. 

Unplug the cable when the Mr Fog Switch charging light turns green. If your device is not rechargeable, wait 30 minutes for the charging process to finish and then disconnect.

Mr Fog Side Effects Explained 

The Mr Fog Switch contains nicotine, propylene glycol, vegetable glycerin, and flavorings. While vaping is considered an alternative to smoking, use of the Mr Fog will lead to the following adverse effects:

1. Nicotine Addiction

According to a report by the Canadian government, nicotine gets highly addictive over time. It leads to cravings, withdrawal symptoms, and more compulsive use.  

2. Dehydration 

The vape ingredients absorb moisture from mouth/throat tissues. Also, as indicated by Urology Health, nicotine (derived from any smoking or vaping) increases urine output. So, urine will cause dehydration symptoms like dry mouth, skin and lips, thirst, headache, fatigue, and dizziness. 

3. Allergic Reactions

Though rare, some users sometimes experience allergic reactions too (as reported in Podsalt.com). The allergy happens from propylene glycol, vegetable glycerin, or flavorings used in the Mr Fog devices. 


So, how to use Mr Fog Switch? Take the Mr Fog Switch, and you’ll notice a switch on one side marking two distinct flavors. Toggle that switch to pick which flavor you want to vape. Then, breathe in through the mouthpiece to automatically engage the draw-activated vapor production. 

No charging or refueling is necessary. Play around with mouth-to-lung and direct-inhalation techniques to discover your favored method for optimal throat hit and satisfaction. It is easy to use and satisfying to vape.

So, Mr Fog Switch is an excellent device for anyone who wants to enjoy vaping in a fun way. Happy vaping!
