When to Throw Out Period Underwear: Signs and Tips

1. Reduced Absorbency or Leakage

If you notice your period underwear no longer absorbs well or starts leaking even after washing, it’s a sign the absorbent layers are worn out.

2. Persistent Odors

If unpleasant smells remain despite thorough washing and proper care, bacteria or residue may have built up beyond repair.

3. Fabric Damage

Look for thinning fabric, holes, stretched-out elastic, or any tears. Damaged waterproof or absorbent layers reduce effectiveness.

4. Stains That Don’t Come Out

If blood or other stains remain after multiple washes and stain treatments, it may be time to replace them.

5. Age of the Underwear

Period underwear typically lasts 1 to 2 years with regular use and care. Over time, materials degrade even if they look okay.


How to Extend the Life of Your Period Underwear

  • Rinse immediately after use.

  • Wash with gentle, fragrance-free detergents without bleach or fabric softeners.

  • Air dry thoroughly and avoid tumble drying.

  • Rotate multiple pairs for less frequent wear and washing.


When You Should Definitely Replace Them

  • After 1-2 years of regular use.

  • If you notice any of the signs above.

  • If the fit becomes loose or uncomfortable.


Pro tip: Keep an extra pair or two handy so you can rotate and prolong the life of your collection!
