What material is Miacup made from? Is it safe?

Miacup is made from an imported, FDA-approved medical-grade silicone rubber. This material is comfortable, highly durable, completely biocompatible (that is, not harmful to living tissue) and hypoallergenic (suitable for women with allergies, including latex allergies).

Some women are understandably concerned about silicone's association with the breast implant scares of the early 1990s. In fact, the material used in Miacup is very different to the one that was used in breast implants.

The controversial implants were made from a fluid-like silicone gel held in a sac. These sacs were known to rupture and leak, potentially causing problems.

Miacup is made from a solid, stable rubber form of silicone. In this form, there is no way for anything to leak into the body. In fact, silicone like this has been successfully used for many years in medical tubing, baby bottle teats and even permanent surgical implants like heart valves and joint prostheses.

The effects of the material on human health have been extensively studied in both laboratory and clinical settings.

Are the pigments used by Miacup safe?

Miacup is produced using the finest international pigments available anywhere. Every pigment is FDA approved and is supported by USP Class VI biological testing including systemic toxicity studies, intracutaneous studies, muscle implantation tests and hemolysis tests.

What are Miacup's measurements?

Height with stem
Height w/o stem
Max. Capacity*
Size 1 (small)
Size 2 (large)

*as measured to cup's absolute capacity, ignoring placement of holes. Since the surface-tension of menstrual fluid normally prevents leaking through the holes, this is also a reasonably accurate figure in practice.

For both models, there are 2 holes just below the top rim, approximately 2mm in diameter. Miacups manufactured before May 2009 have 4 holes, approximately 0.8mm in diameter. The holes were changed on newer models due to customer feedback, in order to make them easier to clean.

What internal/external writing is there on Miacup?

We realise that many women prefer the comfort and cleaning-convenience that comes with a smooth menstrual cup surface. As a result, we decided to keep all emellishments to a minimum. There is no writing anywhere on the cup surface and no measurement lines - the only visible branding being a subtle raised "petals" logo on the inside of the top rim. The logo itself is a one-piece design, which tends to minimize cleaning troubles.

The outside of the cup has one pronounced main ridge to aid in the creation of a vacuum seal, and 7 minor ridges to aid in gripping and removal.

How long does Miacup last?

The material that Miacup is produced from is used in permanent surgical heart valve implants and is highly durable. With proper care, a single unit can last for years - often as many as ten.

In practice, women will usually replace their Miacup for one of three reasons:
1. They accidentally damage or lose their cup.
2. They require a different Miacup model after childbirth or after some years of use.
3. They simply prefer to purchase a new one every year or two, given the product's nature.

So, to answer the question: it's largely up to you.

Is it necessary/adviseable to replace Miacup every year or every other year? I see that some other menstrual cup brands make this recommendation.

This is absolutely not necessary. We cannot speak for the motivation behind any such recommendations, but there is no technical, health-related or regulatory reason why this should be necessary. Menstrual cups have always been designed to last hygienically for years. The medical-grade silicone that Miacup is manufactured from, is the same material used in and approved for use in many permenant surgical implants.

Having said all that, some women do prefer to replace their menstrual cups periodically - but this is then a personal choice and not one that we feel they should be pressured to make.

Are specialised cleaning products necessary or advised for use with Miacup? I see that some other menstrual cup brands market specialised cleaning products.

These are absolutely not necessary and are most often just standard cleaning products that have been rebranded.

Can I sterilise Miacup with peroxide or bleach?

Generally, we recommend avoiding harsh chemical agents just to be on the safe side (and since alternatives like boiling are available). Given the wide number of agents on the market, it is impossible for us to test the effects of every cleaning product on Miacup. In theory, harsh chemicals could have an adverse effect on the material used to produce our cups.

Having said that, silicone rubber is generally very resiliant and shouldn't be effected by most standard forms of household peroxide or bleach.

If you do decide to use any chemical agents on your Miacup, just keep an eye out initially to make sure that they're not having any unwanted effect on the material.

Also, note the importance of rinsing Miacup off thoroughly after the use of any chemical agents: you want to make very sure that any residue is removed before you insert your cup.

Can I sterilise Miacup in a microwave?

It shouldn't be a problem. Please make sure, though, to follow the directions below carefully (particularly the steps concerning safety):

1. Place your Miacup in a microwaveable cup/container filled with enough water to cover your Miacup completely. The cup/container should be big enough to do this without being more than 3/4 full.

2. Turn the microwave to high and let it run until the water in the cup/container starts boiling. Depending on the power of the microwave and the amount of water, the time this takes will vary so keep an eye out and note it for future reference. (As a guide, it takes a 1000W microwave approximately 1 minute to boil an average-sized cup of water).

3. Once the water has started boiling, let the microwave run for another 2 to 3 minutes. That is, you want to keep the cup submerged for 2 to 3 minutes of actual boiling. If you're sterilising your cup before using it for the very first time, let it boil for 6 minutes instead of the usual 2 to 3.

4. Once the microwave timer goes off, open the door but allow the water to stop boiling completely before you remove the cup/container.

5. Keep the water away from your face and body until you're certain that it's safe. While it's unlikely to occur (especially with your menstrual cup inside), it is possible for a microwave to "superheat" the water. Superheated water is incredibly hot (above boiling point) but doesn't appear to be boiling until it is agitated (for example, by movement). When it is agitated, it can suddenly begin to boil violently, causing a serious safety hazard.

What kind of lubricant can I use with Miacup?

We recommend only water-based lubricants for use with Miacup. Silicone or oil-based lubricants can damage Miacup over time.
