What Is Filler Material?

filler-materialThe filler is an absorbent material placed inside the flavor cartridge or cartomizer and designed to hold the e-liquid and regulate its flow to the atomizer in order to avoid flooding and leaking.  It is usually a light, cotton-like fiber that does very good job of retaining fluid. Still, some e-cigarette users are less than satisfied with the quality of basic filler material and constantly search for superior alternatives. Some swear by a material called ‘Fluval’, tea-bags and coffee filters and even cotton swab. I personally stick with the common fillers and don’t recommend messing with any other substitutes.

One of the major issues of cartridge and cartomizer filler material is that it needs to be kept moist at all times. If you fail to add more e-liquid before the filler dries up, it will burn and refilling it after that happens is pointless. It will retain that disgusting burnt taste no matter how flavorful your juice is.

Filler material cannot be replaced, but there are a variety of ways you can clean your cartomizers if you want to re-use them with different e-liquid flavors. However, cartridges and cartomizers are usually very cheap, so most people prefer to throw them away after a few refills.

    I just received a package of new V2 cartridges. They’ve made some changes that I don’t think I’m happy with. They have much less filler in them. They produce significantly less vapor. They don’t last as long as they used to. And they don’t convey as much flavor. I’ve used up one package & am now on the second. V2 is incredibly slow with deliveries. After two months of not receiving my order,I wrote numerous emails to the V2 customer support people, but they never answered. I have still not received a package of cartridges from them, & it’s been 4 months since I ordered. I gave up. I went through another vendor who sells V2 products. I’m happy with the new company, but not with the “improved” V2 cartridges. Is anyone else experiencing problems like this? I’d really like to hear from people who have.

    I use a coolfire 4 subohm vape – it’s great. You can change the cotton on the coils easily, and it seems you can continue this cycle many, many times. Although I have 5 separate coils for my vape, it’s only for the purpose of a quick changeover. Not one of them has needed to be replaced in 2 years. SO save the planet a little and change that old cotton when it tastes a bit shitty. You’ll save a packet too.
