7 Best Mouth To Lung (MTL) Vape Tanks For 2023

We first encountered Nautilus 3 when it debuted with the Zelos 3, and it instantly became one of the best aspects of the kit. Why? There are several reasons. 

First is its design. Frequently, MTL tanks can be basic in design, but the Nautilus 3 Tank delivers a stunning package. It is a little chunkier than some MTL tanks but still sits comfortably on most all vape mods. We said most because there is a little bit of an overhang with skinnier mods. 

Another reason why we love the Nautilus 3 is it’s fully compatible with the long-celebrated Nautilus Coil series. What does this mean for you? Well, you get to access coils in different resistances, ranging from isha-style 0.4ohms to cig-esque 1.8ohms. Our favourite is the 1.8ohm coil because of the flavour that it delivers! 

We also love its refill port! Most vape tanks have a flimsy rubber hatch, but the Nautilus 3 rocks a sliding-top refill mechanism that is rigid and stiff, but in a good way. Whenever we had to top up the tank with juice, there was no wobble, whether open or closed. And most importantly, there were no leaks! 

But the best feature we really admire is that you can replace its coil with a tank full of juice. We know sounds gimmicky, but trust us. It’s a game-changer. 

In summary, we believe that the Aspire Nautilus 3 Tank has it all. It’s user-friendly, durable and boasts impressive tank features, making it MIST’s choice for the best MTL tank in 2023.

Verse Vape: Compatible with both MTL and DTL coils 
Air Supply: Large air inlets for high VG vaping 
Long Draw: Lengthened mouthpiece for optimal MTL inhales 

Lost Vape is best known for its cloud kits, ordinarily aimed at a passionate RTA-using fan base. But when we looked at the UB Lite Tank, it soon became apparent that we were dealing with a rather versatile piece of vape gear.

The Lost Vape UB Lite Tank appears at first glance to be an exclusively MTL tank, with a mouthpiece that suits mouth-to-lung inhales. But the bulky, colourful steel casing hints at a cloudier functionality.

While the 1.2ohm UB Lite Coil delivers a richly flavoured and deeply satisfying MTL inhale, the 0.3ohm coil that comes included is perfectly designed for use with high-VG e-liquids.

This makes the Lost Vape UB Lite Tank remarkably versatile, with lower ohmages on offer than even the Nautilus 3 can match. This makes the UB Lite Tank one of the best options for MTL vapers who enjoy the occasional cloudy diversion.

Flava Fave: Rich flavour from the Aspire BVC Coils 
Off The Top: Easy top refilling system 
Skinny Fit: Thin enough to sit comfortably on any mod 

Most mouth-to-lung vapers are flavour chasers. And we’re confident that the K Lite Tank will deliver you the most flavourful puffs ever. 

Also made by Aspire, the K Lite Tank uses the BVC Coil series. Keep in mind that these are different from the mentioned Nautilus coils, they do, however, feature the same organic cotton and kanthal materials to deliver intensely flavoursome inhales.

In order to maximise the flavour from the coils, Aspire placed a tight airflow ring at the base of the tank. When we closed it, we received a tighter, more concentrated “beam” of vapour. In our experience, it’s the best method for flavour production, which this tank is geared towards.

The ‘tight’ vapour delivery is also assisted by the long and tapered mouthpiece, which we felt was reminiscent of a cigarette filter.

Another great feature is that you can refill the tank using the top cap. Our team was pleasantly surprised to find that it’s child-proofed. 

So, when taste is your primary focus, we highly recommend the Aspire K Lite, the best MTL tank for flavour in 2023.

Taifun Tough: Made in collaboration with Taifun
Naughty Nautilus: Huge selection of MTL and DTL coils to use 
Durable Draws: Built with less exposed glass and more rigid steel 

We know. There are a lot of Aspire tanks in this review, but Aspire makes some of the best MTL vape tanks in the market now. So, what makes the Aspire Nautilus GT a great choice? Well, the Nautilus GT is a sturdy MTL tank. 

Made in collaboration with Taifun, the Nautilus GT features a far bulkier steel construction, which feels armour-plated in places. Knurled steel – a hallmark of Taifun design – surrounds the refill and adjustable airflow sections, as damage to these sections can be fatal for your MTL tanks.

While you don’t enjoy the convenience of a sliding top-fill design like on the Nautilus 3 Tank, the Nautilus GT adopts a traditional quarter-turn unscrew, made easy and comfortable with the knurled grip-ring.

Once again, the tank utilises the Nautilus Coil system, a huge range that you can find in any vape store you ever walk into, ensuring your tank doesn’t require hard-to-find components to operate.

With a minimised yet clear window section and increased use of steel materials, the Aspire Nautilus GT Tank is a hardy MTL tank that you’ll find easy to use and satisfying to vape from.

Vaping Value: Very affordable MTL vaping tank 
Going Clear: Attractive translucent acrylic design 
Easy Pea-Z: Innokin Z Coils are easy to install and provide great MTL hits 

If you’re looking to vape on a tight budget, then the Innokin GO Z Tank provides the whole MTL experience at a reduced cost.

Innokin is able to provide a low-cost vape tank by keeping manufacturing costs down by using primarily acrylic materials for the GO Z Tank’s build. Despite being admittedly a little more fragile than other tanks, the GO Z can still deliver rich and satisfying MTL vape hits.

Despite being a value vape, the GO Z Tank is fitted with Innokin’s Z-Coil series, ordinarily seen in their Zlide and Zenith Tanks. They come in 1.6ohm and 0.8ohm variants, which are excellent for MTL vaping. There’s also a 0.4ohm coil for those who want to take their tank to the cloudier side of the tracks.

Though it uses acrylic materials, we found that the GO Z still boasts sophisticated tank design elements, such as a sliding top-fill mechanism and a remarkably ample adjustable airflow ring to help you customise your vaping experience.
The Innokin GO Z Tank may not be the hardiest vape tank featured today, but if you’re looking to vape while counting the pennies, you can still enjoy a robust piece of vaping hardware.

Salty Ohms: TECC GTL Coils ideally suited for nic salt use 
Armoured: Tank surrounded by a tough steel ring 
Easy Fit: Coil installation is simple thanks to the push-to-fit design 

While TECC may not be a household name like many other tank manufacturers featured today, they impressed our team with this offering!

The TECC Impact GTL Tank is a sleek and modern hybrid of steel and acrylic construction, reflecting the increased popularity of pod-style tank designs. It takes the TECC GTL Coils, which are available in 1.2ohm and 0.8ohm. During our tests, we were pleasantly surprised that both coils performed great with nicotine salts. 

Another aspect we loved was the knurled steel on the airflow control ring. It gave us far more precise control than the usual materials used, a pleasant surprise on a tank that is half acrylic. The sliding top fill makes nic salt refills a doddle. We were able to top up the tank even when moving because we didn’t have to juggle any removed components.

With simple use and hardy coil materials, the TECC Impact GTL Tank is the best MTL tank for nicotine salts.

Super Soaker: Meshed coils absorb juice quickly to prevent leaks 
New Tricks: New coil variants bring the T20S design into the future 
Quick Check: Wide windows make it easy to gauge juice levels 

The Innokin APEX Tank is a spruced-up iteration of their classic T20S Tank but now includes a better refill system, improved coils, and a lessened likelihood of leaks.

The new coils may resemble the classic Prism-S design, but it now includes meshed interiors. When we tried the new coil, we got more flavour because its meshed build allow faster and more evenly spaced vape juice absorption. 

Another upgrade that we love is the interior, which was tweaked to facilitate better e-liquid storage. There’s also a newly designed airflow ring that’s more resistant to spillage and e-liquid leaks.

The APEX was initially intended to sit snugly atop the APEX Kit, but with a 510-threaded connection, you can pair it with any mod that you like.  

The Innokin APEX Tank is a relatively simple piece of kit that’s easy to use, capable of excellent flavour production, and highly resistant to the annoying e-juice leaks that can often plague vape tank designs.
