The shelf life of opened e-cigarette cartridgers is usually three months. Some brands recommend using them up within 15 days. The details are as follows:
General recommendation:
Most brands (such as Relx) recommend that the opened cartrpers be used up within three months. Beyond this period, the taste and smoke volume of the cartritges may significantly decline, and even harmful substances may be produced, affecting health.
Extreme situation:
Some brands or users have reported that the best effect of the opened e-liquid is achieved within 15 days. This is because the e-liquid comes into contact with the air and is prone to oxidation. It may also absorb moisture from the air, leading to changes in taste and the concentration of the e-liquid.
Individual Cases and General Laws:
Although some users have indicated that the opened cigarette cartridly can still be used after being placed for more than half a year, this is an isolated case and cannot be regarded as a universal rule. To ensure safety and taste, it is recommended to follow the brand's recommended shelf life.
The method for determining expiration:
Taste change: If the taste of the cartridge deteriorates or the amount of smoke decreases, it may have expired.
Abnormal smell: If the smell of the cartridges has become weak or has an odd smell, it may also indicate that they have gone bad.
