Gynecologists confirm that a bacteria inhibiting coating on period underwear is indispensable.
We are the only brand to have had the bacteria-inhibiting effect of our products tested. The antibacterial effectiveness has been confirmed by an external laboratory and is tested at regular intervals. This means that the use of the bacteria-inhibiting agent counteracts the formation of odors and proliferation of germs.
The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.
It is very important to us that we communicate transparently in this regard.

Depending on the model the ooia period panty is designed to hold 1-6 tampons or 10-30ml of fluid. How many and when to use ooia period panties depends on your needs - your preferences, your plans, the heaviness of your menstrual flow, and many other factors. To cover one period completely you need about 5 ooia Period Pantys - assuming that one is worn at night, one during the day, and that the used panties are washed after two days.

How many and when to use ooia period panties depends on your needs - your preferences, your plans, the heaviness of your menstrual flow, and many other factors. There is no one-size-fits-all solution. If your period is light to medium, you can most likely use ooia period panties without additional period products. If you are bleeding heavily, you may want to use additional protection (tampon, cup).
If you treat ooia period underwear well, it will retain its full bacteriostatic effectiveness for about 2 years. After that, you can of course continue to use them as "normal" underwear - although studies say that underwear is rarely used for longer than two years. But we are happy if ooia is used for longer.
