The potential harm from heating polyester and inhaling is serious business. This is new territory for all and we'd like to think we're doing something safer than inhaling cigarette smoke.

It first occurred to me when looking at my 510 that the short distance to the atomizer would place the heating element right inside my cartridge. This was the case, you can even occasionally notice the slight indent on the filler.

To illustrate

I took some quick measurements and built a very quick 3d scene to highlight my point.

....

When I first purchased my 510 it was a pleasure to smoke - I gave up analogs right away. 3 weeks in I'm noticing a hot sensation on a more regular basis and dirtier smoke that simply doesn't taste right.

A new 510 atomizer is a clean device, it heats and produces no smoke.
But if you add an empty cartridge to the mix with no E-juice inside, I quickly found the source of that taste, it's a semi-sweet burning taste that I'm now quite certain comes from the melting polyester. 8-o I was not pleased to have found this discrepancy after chain vaping on a regular basis.

.....

The solution was simple - push/stuff the filler material deep down into the cartridge (at least .7cm) and saturate the device with 4-6 drops. Eliminate any contact between the atomizer and the filler material. The smoke take a short while longer to atomize, but is now about 10x smoother, much less bothersome on my throat and I can taste much more of the intended flavor.

*Prior to this I was just dripping 2-3 drops and having to re-fill after only several hits due to the weird flavor.

Perhaps I'd overlooked something that was common knowledge! Either way I hope that a month of smoking polyester causes no long term damage.

.....

I sincerely apologize if I create any fear among E-Smokers, it's not my intention. This has been a really easy transition for me and quitting analogs was a breeze. But I think it's absolutely imperative that we share all findings, all of the time.

Last note.

good point! btw nice 3d graphics! time to make a clear cart so we can see the vapor move through the e cig

How does it wick if the filler isn't contacting the atomizer bridge at all?

I was wondering the same thing....

Thanks. I think that's a great idea. Better yet, some way to eliminate the wick altogether without dripping.

I'm not an expert, perhaps heat is enough.

There's a happy medium to be found if you play around for a while. I've been experimenting with new atomizers and fresh cartridges for a few hours, ensuring I eliminate that taste before adding any juice.

About .7mm - 1cm seems to do the trick.

amazingly i just tried this and it seems to work. I'm gooing to see how this goes for the rest of the day

InTheCity, you are more likely to get a nasty burned taste that way - because the cartridge filler is designed to touch the mesh/wire wool bridge, and if it doesn't, your liquid will not get wicked down to the atomizer coil, and then the threads in the coil itself will start to burn.

The mesh bridge you are seeing is not the heating element. The heating element is the coil below the mesh bridge. It sits in a tiny ceramic cup. Without the wicking mechanism of the cart filler touching the mesh bridge, you are destined to eventually really dry out your atomizer coil and end up with a bad, burning taste.

Here is a link to a couple of pictures showing what you are not seeing -the heating coil itself, underneath the mesh bridge:

@yvilla

I'll edit my original post by pointing to yours first, you clearly have more understanding than I do and I don't want to create any confusion.

But I do wonder though, why a fresh atty vs a fresh empty cart produces this sweet test. Especially since the burning of polyester is characterized by a sweet smell/taste.

"Polyester's melting point of about 460°" so perhaps its not burning to a dangerous temperature. What's a ball park average on the atomizers temp?

You never cease to amaze me.... Keep on, keepin' on! One day I'm gonna be smart too!

you can always bypass the filter thing and drip into the atomizer. i've decided to do this full time. no more worries about vaping poly.

I wish it were more apparent how to actually do this without messing up your atomizer. I see a lot of talk on the subject, but no guide.

I think it's like this:

1. Remove your poly so you have a cart without any liquid or filler in it.
2. Drop 2-3 drops directly onto your atomizer
3. Put the empty cart on the end
4. Take a drag

I don't do this, and it's not typically recommended (though I dunnoe why not) but sometimes, after a session of chain vaping, when my 510 gets all heated up and yummy I will pop an empty end on it and vape the last bit until there's less flavor. Then I will clean up, refill a cart, and begin again.

The whole point of changing the cart material to the 'hemp' tea bags was to get rid of any chance of vaping polyester.....even if they didn't work as well as the polyester.
Apparently the pyramid tea bags are wicking very well as long as you get the method right and although they are made of nylon there isn't much chance of any stray fibres being burnt on the coil because it's a woven material. I think anything is better than risking vaping polyester and if you do get any polyester on the coil you will know it because you can't mistake the plastic taste or get rid of it once it's there.

By the way love the Graphics
