How often should you throw out period panties?

Period panties are one of the most comfortable and eco-friendly ways to manage your menstrual cycle — but like any reusable product, they don’t last forever.
So how long do they really last, and when should you throw them out?

Let’s break it down.

👙 How Long Do Period Panties Last?

Most high-quality period panties last between 1.5 to 2 years with proper care.
That’s roughly 20–30 menstrual cycles, depending on how often you use and wash them.

Some brands may last longer, but the key factor is how you care for them — the better your maintenance routine, the longer they’ll stay absorbent, soft, and leak-proof.

🧺 Signs It’s Time to Replace Your Period Panties

Here are some clear signs that your menstrual underwear may be ready to retire:

  1. Leaks or damp spots
    – If they start leaking or feeling wet sooner than usual, the absorbent core may be wearing down.

  2. Loss of elasticity or shape
    – When the fit becomes too loose, it can allow blood to leak out the sides.

  3. Persistent odor
    – If they smell even after washing properly, bacteria may have built up in the fabric.

  4. Damaged fabric
    – Holes, thinning, or frayed seams can affect performance and hygiene.

  5. Reduced absorbency
    – If they no longer hold as much as before, it’s time to replace them.

If one or more of these signs appear, it’s best to throw them out and get a new pair.

🧴 How to Make Period Panties Last Longer

To get the most out of your investment, follow these simple care tips:

  1. Rinse after every use
    – Rinse in cold water until it runs clear to prevent staining and bacteria buildup.

  2. Use gentle detergent
    – Avoid bleach, softeners, and harsh chemicals that can damage absorbent layers.

  3. Machine wash cold
    – Use a delicate cycle or wash them in a mesh bag to protect the fabric.

  4. Air dry only
    – Heat can weaken the waterproof barrier and elastic fibers.

  5. Rotate pairs
    – Having 3–5 pairs to rotate helps reduce wear and tear from frequent washing.

By following these steps, your period panties can easily last up to two years or more without losing effectiveness.

🌿 Why It’s Worth Replacing Them Regularly

While replacing your period panties every couple of years might sound like a chore, it’s actually:

  • More hygienic – Prevents bacterial buildup.

  • More reliable – Ensures leak-free protection.

  • Better for comfort – Keeps the fabric soft, flexible, and breathable.

Think of it like replacing a favorite bra or workout leggings — with time and use, even the best fabrics wear out.

💬 Final Thoughts

So, how often should you throw out period panties?
🩱 Every 18–24 months, or sooner if you notice leaks, odor, or loss of absorbency.

With the right care, they’ll keep you feeling fresh, secure, and confident through every cycle.
