The shelf life of opened e-cigarette cartridters is usually 15 days to 3 months, with the best taste period being 2 to 3 days. The specific duration is affected by the brand, storage conditions and usage frequency.
1. Regular shelf life
Most brands recommend that it be used up within 15 days after opening. For instance, some brands have pointed out that after opening, cigarette cartridts can be stored at room temperature for about 15 days, but the optimal taste period is only 2 to 3 days.
Brand differences: Some brands (such as Relx) recommend using it up within three months after opening, but emphasize that the best taste period is relatively short and it should be used as soon as possible.
2. Factors affecting the shelf life
Storage conditions: High temperature, humidity or direct sunlight will accelerate the deterioration of e-liquid, resulting in a reduced taste or the production of harmful substances.
Frequency of use: Frequent use will accelerate the oxidation of e-liquid and shorten its shelf life.
3. Best preservation method
Environmental requirements: Store in a cool and dry place, away from direct sunlight. The temperature should be controlled between 15℃ and 25℃, and the humidity should be maintained at 40% to 60%.
Storage method: Store upright to prevent e-liquid leakage. The remaining part after opening should be sealed with the matching lid.
4. Risk of exceeding the shelf life
Taste change: After e-liquid oxidizes or absorbs moisture, its taste may become milder or develop an unpleasant odor.
Health risk: Expired cigarette cartrids may produce harmful substances that can affect respiratory health.
Suggestion: After opening, it should be used up within 15 days. If you want the best taste, it should be finished within 2 to 3 days. If long-term storage is required, refrigeration (not freezing) can be considered, but it is necessary to ensure that the cartridges are well sealed to prevent condensation water from entering.
