bacteria inhibition

Your health is our top priority.

Gynecologists confirm that a bacteria-inhibiting coating on period underwear is indispensable.

This prevents odors and the multiplication of pathogens.

We are the only brand that has had the bacteriostatic 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 the multiplication of germs.

The bacteria-inhibiting effect of the silver chloride takes place directly in the fiber.

We attach particular importance to communicating transparently here.

EU Regulation No 528/2012: biocidal active substance is silver chloride.

No nano particles are used.

All marked ooia products are certified according to STANDARD 100 by OEKO-TEX [21.0.46579 HOHENSTEIN HTTI]www.oeko-tex.com/standard100". This means that all individual components of ooia, from fabrics to yarns and labels, have been tested for harmful substances and have thus been classified by the Hohenstein Institute as harmless to health and skin.

still have questions?

How many ooias do I need for one period?

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.

Can I use my ooia without needing other menstrual products?

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. 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).

How long can I use my ooia products?

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.
