As the DIVA Cup is a personal care product, we recommend that you inspect your cup regularly for signs of deterioration such as a sticky or powdery film, severe discolouration, odor, etc. If you detect any deterioration, or if you experience irritation, we recommend you replace your DIVA Cup with a new one. The lifespan of your menstrual cup may vary, depending on vaginal pH, how often and how well your cup is cleansed, what cleansing agents are used, etc. Our general guideline is that a DIVA Cup can last up to 5 years, but it is ultimately up to the consumer to decide when to replace their cup.
