Period underwear is not only comfortable, but also a sustainable choice.
However, many women wonder: how long does period underwear really last? The answer depends on how often you wear it, how you wash it, and how you store it. With proper care, period underwear can last for many years — making it worthwhile both environmentally and economically.
What determines the lifespan of period underwear?
The average lifespan of period underwear is between 5 and 7 years.
The absorbent layers are designed to be washed repeatedly without losing their effectiveness.
How many times can it be washed?
Period underwear can easily withstand hundreds of washes, provided you follow the care instructions:
-
Rinse the underwear in cold water after use
-
Then wash it at 40°C maximum with a mild detergent
-
Leave it to air-dry
Fabric softener, bleach, and high temperatures significantly shorten its lifespan.
When should you replace period underwear?
A common question is: how do you know when it’s time to buy new ones?
It’s not the appearance, but the performance that matters.
After years of use, a pair of period underwear may look a little less “new” while remaining perfectly hygienic as long as it still absorbs well and does not leak.
If you notice that the absorbency has decreased or that the fabric in the crotch area has become thinner, it’s time to replace the underwear. With normal use and proper care, this only happens after several years.
How should period underwear be stored?
After washing and drying it completely, it is best to store period underwear in a dry, well-ventilated place, like your other underwear. Avoid enclosed, damp spaces.
When traveling or on the go, a breathable or waterproof pouch can be practical, but at home, it is advisable to simply let the underwear “breathe” in your drawer.
By washing and storing your period underwear properly, you considerably extend its lifespan. This allows you to enjoy years of comfort and peace of mind while reducing your waste with every cycle.
A small gesture with a big impact — for you and the planet.
