Best Menstrual Sponge Reviews

Best menstrual sponge

Interested to try a menstrual sponge but wondering what is the best menstrual sponge out there?

To be honest, when I first came across menstrual sponges while searching for alternatives to tampons and pads, I was fairly intimidated when I read about sea sponges.

A quick search on google on sea sponge indicated that the sea sponge is technically an animal.

From Wikipedia,

Sponges are animals of the phylum Porifera (/pɒˈrɪfərə/; meaning “pore bearer”). They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them… Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.”

I was not ready to explore further and left it at that. Until I realized menstrual sponges are also available in synthetic versions.

Reviews of converts raving about the comfort of wearing sponges in place of tampons, and how they provide good leak protection and an odor free experience made me sit up and pay attention.

Oh, the fact that some of them buy it to actually wear it during intercourse when they have their periods, doesn’t hurt too.

Color me intrigued.

What Are Menstrual Sponges?

A menstrual sponge basically functions as its namesake – as a sponge.

You simply insert the menstrual sponge up your vaginal canal, absorbing the menstrual flow.

Menstrual sponges are touted to be soft and comfortable to wear (almost can’t feel it!) and rather leak proof.

The recommended changing time is every three hours, but it is really dependent on your flow volume.

There are two types of menstrual sponges in the market – sea sponges and synthetic menstrual sponges made from hypoallergenic material.

What Are Sea Sponge Benefits?

Menstrual sponge fans credit sea sponges for being all natural (from the sea), and thus chemical free.

The Sea Sponge Company elaborates,

“Natural sea sponges, while remaining hypoallergenic and toxin-free, actually possess enzymes that are shown to inhibit the growth of mold, mildew, and bacteria. This is just another reason that sea sponges are considered healthier, safer, and more effective for various cosmetic and personal care applications.”

(See the video below to learn more interesting facts about sea sponge.)

In addition, as sea sponges are reusable for up to six to twelve months, it is also easy on the wallet and hence more environmentally friendly.

Another environmental win is that when harvested sustainably, sea sponges becomes a good renewable resource.

In terms of comfort levels, some women who had tried tampons and menstrual cups, remarked that wearing a sponge is even more comfortable! They are also often surprised by the good level of leak protection offered by menstrual sponges.

Sounds Good. But Are Sea Sponge Tampons Safe?

Some critics question the sanitary standards of sea sponges. In a recent blog post, Dr Jen Gunter questioned the biological safety of sea sponges.

The grossness of a debris and “various other materials” containing vaginal sponge aside there are real potential safety concerns. Bits could break off and become a nidus for bacteria, the sponge itself could have harmful bacteria, sponges may change the vaginal ecosystem promoting the growth of good bacteria, the inability to clean them adequately between uses may reintroduce potentially harmful bacteria that was breeding in the wet sponge sat drying beside the sink, and the sponge may cause abrasions during insertion and/or removal.”

While that being said, many sea sponge users still swear to its safety and benefits.

Are Synthetic Menstrual Sponges Safer?

So for those who are concerned about wearing a sea sponge but still want to try menstrual sponges, one option is to consider trying synthetic menstrual sponges.

Joy Division’s soft tampons, Gynotec and Beppy are examples of synthetic menstrual sponges.

Beppy sponges are made from hypoallergenic material such as medical grade water blown polyurethane foam, and are considered safe to wear inside the body.

With regards to Toxic Shock Syndrome (TSS), Beppy claims that the risks are reduced as compared to conventional tampons on its website because of the materials used to manufacture the sponge.

Based on online reviews of the products, it would appear that synthetic menstrual sponges are equally comfortable to wear, as compared to sea sponges, and appear to offer good leak protection too.

The downside is, synthetic menstrual sponges are less environmentally friendly as they are usually for single usage and hence not reusable.


Where Can I Buy A Menstrual Sponge?

Frankly, the easiest place to buy menstrual sponges are via online shops.

You can either buy it directly from the manufacturer’s website or via Amazon.

They are quite difficult to find in stores, as you are more likely to locate sponges in the makeup department than the sanitary protection department.

How To Use Menstrual Sponge

There are women who use the sponge as a complete alternative to conventional feminine hygiene products like napkins and tampons.

Many women, however, choose to use menstrual sponges on occasions such as visits to the sauna, swimming or during intercourse.

To use a menstrual sponge (especially if you are using a sea sponge), you may want to consider to trimming the sponge (when dry) to size for a better fit.

That being said, menstrual sponge manufacturers these days do already sell sponges in different sizes.

If you are using a sea sponge, while most of the sponges should already be carefully processed and cleaned, you should still check it for any debris like shell bits, or coral just to be sure, before you use it the first time.

How To Insert And Remove A Menstrual Sponge

A dried sponge is normally quite stiff, and will soften dramatically when wet.

So, moral of the story – soak and rinse the sponge in warm water multiple times, then squeeze out the excess water before using it.

As a beginner in using a menstrual sponge, it is recommended to thread through the sponge with a cotton thread (or use unwaxed dental floss), to aid with removal.

In actual application, just use the sponge as you would with a menstrual cup or a tampon.

Pro tip- squeeze the sponge into as small a ball as possible before insertion. The sponge will then naturally expand when released inside. This makes for a more comfortable insertion.

Insert it in about 2-3 knuckles in, but the actual distance is actually depending on your cervical position.

If you have a low cervix, the sponge might not even make it past 2 knuckles of your ring finger.

The general benchmark of a good distance is when you feel comfortable with it in, or even not feeling it there at all.

To remove it, just reach in with your finger, or pull out the string (if you have threaded it).

If you are reaching in to remove it, try not to squeeze the sponge too hard while removing it (to avoid squeezing out flow).

Rinse it out well in water multiple times (until it does not feel slimey), squeeze dry and reinsert it.

Easy peasy.  

How To Clean Natural Sea Sponges

In terms of care, if you are using non reusable menstrual sponge, care is a non issue.

If you prefer to use a sea sponge, a little effort is needed in maintaining and cleaning it.

There are a couple of ways to clean a menstrual sea sponge.

You can either soak the sponge:

  1. in a solution of tea tree essential oil (a few drops of tea tree essential oil in 1 cup of warm water) for 10 minutes, or
  2. In a solution of vinegar (1 tablespoon of apple cider vinegar or white vinegar to 1 cup of warm water) for 10 minutes.

If you are in the mood for more heavy duty cleaning, soak the sponge in a hydrogen peroxide solution (¼ cup of hydrogen peroxide in a cup of water).

For longevity of sponge, you may want to consider soaking the sea sponge in a baking soda solution (1 tablespoon of baking soda to 1 cup of warm water) every other week for 10 minutes.

Then rinse and squeeze out excess water before letting it dry (either leave it in a hanging mesh bag, or dry it out in the sun.

Do make sure your sponge is completely dried before next use.

Maintenance of menstrual sea sponges during period is similar to the above, just soak it in the baking soda solution at the end of every day after use.

Make sure you have a few sea sponges in rotation so that you won’t run out of them while waiting for them to dry.

If you notice your sea sponge becoming frayed, simply snip off the loose bits with a scissor can keep it smooth and extend its longevity.

Avoid the following in care for your sea sponge:

  1. Boiling/microwaving the sponge will spoil the cellular structure (unless indicated otherwise).
  2. Using bleach will weaken the sponge as well.
  3. Drying the sponge in a dryer will spoil it.

Poseidon sponges are safe to boil, so boil away when you receive it for the first time for that thorough cleaning and sterilization.

Maintenance is also a breeze, as these sponges come with a clear instruction sheet and a small bottle of 100% tea tree oil (0.85oz/ 25 ml) to function as an antiseptic and lubricant.

Just add 2 to 3 drops of the oil to 1 cup of warm water to soak the sponge after use to disinfect it for 10 minutes. Rinse it multiple times until it is no longer bloody or slimy. Hang to air dry it, and use it when it is completely dry.

For longevity, soak the sponges in baking soda solution to strengthen its cellular structure. These sponges can last for 3-6 months with proper handling.

Being gentle with the removal process can also prevent ripping the sponge. You can also trim the loose edges to obtain a smoother finish, which can also lengthen the longevity of the sponge.

Our Recommendation

Poseidon sponge set

For people who are just trying out sea sponges for the first time, we recommend you to consider getting the starter set, which consists of 5 pieces of sponges of varying sizes (1.5’’ to 3’’),so that you can experiment with the different sizes to see what suits you the best.

Most Amazon reviewers recommend getting the large set as the larger ones are more porous and hence more absorbent.

We think the large set is suitable for people who know they have heavier flows and have experience using menstrual sea sponges.
