How to use your IQOS Originals DUO

If you’ve just bought your first IQOS heated tobacco device and it seems that there is just a bit more to it than you realised - from charging the Charger, charging the Holder, loading the HEETS to cleaning and maintenance - worry not, for in this guide we’ll show you that it is in fact quite straightforward and in no time we’ll have you on the right track.

Introduction to IQOS

IQOS is a heated tobacco device that uses specially designed tobacco sticks called HEETS. Instead of burning the tobacco, the IQOS system works by heating the HEETS just enough to release a flavourful nicotine containing tobacco vapour. The result is an authentic real tobacco flavoured cigarette-like experience that is cheaper and up to 95% less harmful than burning tobacco. Cigarettes produce tar, IQOS doesn’t.

There are a number of other benefits of using IQOS over Cigarettes:

  • Less than half the cost of a pack of 20 cigarettes. Heets cost £5 per pack of 20.
  • Emits on average 95% lower levels of harmful chemicals.
  • Produces on average 98% less carbon monoxide (CO)
  • Does not produce tar.
  • Leaves no stains on fingers.
  • No fire, no ash, no smoke.
  • Improved breath and lung function.
  • Widely available.


What's in the IQOS box

From left to right

  • 1 x IQOS Originals Duo Holder - Where you insert your HEETS tobacco sticks
  • 1 x IQOS Originals Duo Pocket Charger - Stores and charges your holder, has enough charge for an entire pack of HEETS
  • 1 x Dual Cleaning Tool
  • 1 x Box Cleaning Sticks
  • 1 x Power Adaptor
  • 1 x USB Type C Charging Cable

Step 1: Check & Charge

First off you want to check and see how much charge your IQOS Duo Charger has, or if it has any charge at all. To do this locate the Charger button on the top corner of the Duo Charger. Press and hold the button for 4 seconds. You should see the elongated status light next to the button cycle up, showing how much charge your IQOS Duo Charger has. If you don’t see any lights then that means that you have to charge your kit before you can use it.

To charge your kit use the Type C USB charger and power adaptor provided. The IQOS Pocket Charger will take approximately 2 hours to charge fully. This will provide you with on average 20 sessions or 1 full pack of HEETS.

Now for the Holder (the bit you actually use together with your HEETS). Simply push down on the bottom of the side panel of the Charger and slot your Holder in to charge.

Next to the Charger status light are two dot lights indicating how much charge your IQOS DUO Holder has.

Press and release the Charger button to check this.

1 light indicates 1 use and 2 lights indicates 2 uses. As with the charger, if you don’t see any lights then you’ll have to wait for the holder to charge.

The IQOS DUO Holder will take 5 min 15 seconds to fully charge and deliver its two consecutive uses (max.). If you’re in a hurry, you can get one use in under 2 minutes of charge.



Step 2: Insert HEETS

So you’re fully charged up, now for the fun bit. Take your Holder out of the Charger. Grab a HEETS stick out of your pack and gently press the tobacco side into the Holder up to the line of the filter.

Next you need to start the heating process. Press the Holder button and you should feel the Holder vibrate once and a white light on the indicator button pulse with either 1 or 2 lights depending on the charge.

Your holder will now begin heating the tobacco in the HEETS stick. When it is ready the Holder will vibrate twice, you are now ready to go and can begin puffing on the Filter tip of the HEET as you would a normal cigarette.

Like a cigarette, once it’s lit, it’s lit and each HEETS stick is designed to last up to 6 minutes or 14 puffs, which is roughly the duration of smoking a cigarette. The way you puff will impact how long the HEETS stick lasts.

Once you are finished you can simply slide the Holder cap upwards, pull the HEETS stick out of your device and dispose of it responsibly.

Step 3: Cleaning Your IQOS Device

Even though the tobacco in HEETS tobacco sticks doesn't burn, tobacco residue may accumulate inside of the IQOS Holder when used. With quick, regular TLC you can ensure that your device runs smoothly. IQOS does recommend that you clean your Holder after every pack of HEETS (20 tobacco sticks) and supplied with your IQOS is a specially designed multi-function cleaning brush and a pack of cleaning sticks.  


Here’s how to use them:

Cool it

The first important step is to let the device cool down, about 30 seconds should do it.

Tap it

Remove the cap from your Holder and tap out any loose tobacco from inside.

Brush it

Next you’ll be using the Dual Cleaning Tool to clean any residue from the heating element inside the Holder.

Take the cap off and insert the Rotating Head Cleaner of the Dual Cleaning Tool into the holder and rotate gently for a few seconds.

Take the cap off the other end and insert the Sweeping Head of the Dual Cleaning Tool into the Holder and gently move it sideways from left to right.

Wipe it

Finally insert the Cleaning Stick to wipe any residue you can see on the inside of the Holder. Make sure not to touch the heating element with the Cleaning Stick

And that’s it. You can get back to Enjoying your IQOS Duo.

Guide to HEETS

Each HEETS stick is designed to last as long as a cigarette, roughly up to 6 minutes or 14 puffs. They are designed to be shorter to allow for optimal use with the IQOS Holder.

By heating the tobacco instead of burning it, the true taste of tobacco is released and the taste will differ slightly from what you are used to with cigarettes. Nicotine is naturally present in the tobacco used in HEETS and this is released as an aerosol when heated.



  • Mild: Yellow (light & mellow), Amber (balanced & Roasted)
  • Regular: Teak (rounded & nutty), Sienna (smooth & woody)
  • Bold: Russet (rich & full bodied)



  • Mauve (menthol & berries)

Why is my IQOS Duo Charger Flashing Red?

If your device is flashing red that means that you will need to reset it. To do this, insert the Holder back into the Charger and hold down the Charger button until the lights fade, blink twice and then turn off completely. Then release the button and the lights should gradually fade in to show the reset is complete.

Why is my IQOS Duo Holder Flashing Red?

If your IQOS Duo Holder is flashing red then check to see if the heating blade element has snapped and contact IQOS support for guidance.

Why is my IQOS Duo Holder Flashing White?

This means you need to pop the Holder back into the Charger, it should be fully charged by the time the kettle’s boiled.
