Liquid window
A liquid window is a transparent area in the body through which tank level and sometimes air bubbles are visible. It helps show whether the wick can still be supplied, although tinting or placement may limit readability.
01
Classification
Liquid window refers to a container in the liquid path – the part that fixes capacity, filling method and sealing. Material, seals and filling port decide which liquids stay unproblematic in it over time. The meaning of Liquid window shifts depending on whether marketing copy, a user manual or a datasheet is using the word.
02
Practical relevance
Whether Liquid window works reliably shows in leaks, condensate at the mouthpiece and how evenly the wick is resupplied. Decanting or leaving it standing for a long time has a direct effect here as well. In practice the question about Liquid window comes up together with Cartridge – clarifying one of them usually means half-understanding the other already.
03
Handling it safely
Fill Liquid window only to the marked level and only with a liquid released for this system. Cracks, brittle seals or plastics that have turned cloudy mean replacement, not continued use. Nicotine-containing products in connection with Liquid window are intended exclusively for adults and do not belong in the hands of adolescents.

Not to be confused with
Liquid window is most often confused with Bottom fill, occasionally also with Cartridge – even though the three answer different questions. In practice: when a source uses Liquid window, first check whether it means the word technically or as marketing language.
