You don't need a dedicated steriliser to care for a reusable menstrual cup or disc, but the right device can make between-cycle care easier. Depending on the product instructions, you may be able to use boiling water, a microwave steam container, a plug-in steam device or a portable UV device.
Although these products are commonly called sterilisers, home-use devices are generally intended to sanitise cups and discs and do not clinically sterilise cups or discs. Always follow the care instructions supplied with both your reusable period product and the device you use.
Quick guide: If you want the simplest option without buying another device, first check whether your cup or disc can be boiled. If you want something compact, compare microwave steam containers. If you prefer a dedicated appliance at home, consider a plug-in steam steriliser. If portability and water-free use is a priority, a UV device may be useful if your product instructions permit it and the cup or disc fits and can be positioned correctly.
The most important rule: The best steriliser is not necessarily the one with the fastest cycle. It is the option your cup or disc manufacturer permits and that your product physically fits inside.
Steriliser types at a glance
- Boiling water: usually the simplest and least expensive option when the cup or disc instructions permit boiling.
- Microwave steam sterilisers: compact containers that use water and microwave heat to generate steam.
- Plug-in steam sterilisers: dedicated appliances with their own heating element, usually best suited to home use.
- UV sterilisers: rechargeable, water-free devices that can be useful for travel, provided the product is clean, dry, compatible and correctly positioned.
These methods are not automatically interchangeable. A method that is suitable for one cup or disc may not be recommended for another.
Cleaning vs sanitising: what is the difference?
Cleaning removes menstrual fluid, residue and other visible material from your cup or disc.
Sanitising is an additional care step intended to reduce microorganisms using a method such as boiling water, steam or a manufacturer-approved UV device.
Routine cleaning is different from contamination. Check what to do if your cup or disc falls in the toilet.
A steriliser or sanitising device does not replace washing. Clean your cup or disc first according to the manufacturer's instructions, then complete any recommended between-cycle sanitising step.
What to check before choosing a cup or disc steriliser
1. Check the care instructions for your cup or disc
Do not assume every reusable period product can be cared for in the same way. Manufacturers may recommend boiling, steam, another sanitising method or a particular temperature or cycle.
Some products have material or temperature restrictions. The instructions supplied with your cup or disc should always take priority over generic advice or the instructions for the sanitising device alone.
2. Compare the usable internal measurements
A device described as fitting “most” cups or discs may still be too small for your product. Compare the usable internal chamber diameter and height with the dimensions of your cup or disc.
For discs, one measurement alone may not tell the whole story. A disc may technically fit within the stated diameter but still not sit correctly because of the chamber shape, lid, internal post or the orientation required by the device.
Some menstrual discs need to be pinched into a narrower shape and positioned vertically. Always check both the measurements and the manufacturer's positioning instructions.
3. Think about where you will use it
A microwave option is useful only when you have access to a microwave. A plug-in steam steriliser may be more convenient if you want a dedicated appliance at home.
A rechargeable UV device may be attractive for travel or situations where you do not have easy access to a cooktop, saucepan or microwave, but the product still needs to be cleaned first and may need to be completely dry before the UV cycle.
4. Look beyond the cycle time
A short cycle does not necessarily mean the entire process is faster.
Steam methods require water, setup and cooling time. Microwave containers and plug-in devices can remain very hot after the heating cycle has finished. UV devices may require washing and complete drying before use.
Compatibility, usable chamber size, safe handling and convenience are generally more important than choosing the shortest advertised cycle.
Compare menstrual cup and disc sterilisers
Use the comparison chart to compare sanitising method, power source, cycle time, internal measurements, compatibility and practical features.
Always compare the actual dimensions of your cup or disc rather than relying only on a general “fits most” description.
Shop all menstrual cup and disc sterilisers
Microwave steam sterilisers
Microwave sterilisers use a small amount of water and microwave heat to generate steam. They are generally compact and portable, but every model has its own water level, heating time, microwave wattage and cooling instructions.
Never microwave a dry steam container or run a steam cycle without the amount of water specified in the instructions.
SteriPod Silicone Microwave Menstrual Cup and Disc Steriliser
The SteriPod is a soft, collapsible silicone microwave container designed for menstrual cups and discs. Its compact shape also allows it to double as a storage case.
This may suit you if you want a small microwave option for home or travel. Check the usable internal chamber dimensions against your cup or disc before purchasing.
Saalt Compact Menstrual Cup or Disc Sanitiser
The Saalt Compact Sanitiser is a collapsible silicone option with a relatively wide chamber. Saalt provides instructions for both microwave steam use and a boiling-water method.
The wider opening may be useful for larger cups or discs, but always check that your particular product fits and that its own care instructions permit the method you plan to use.
Ruby Microwave Steriliser for Menstrual Cups
The Ruby Microwave Steriliser is a wide, collapsible silicone microwave container designed for menstrual cups.
It is not described by the manufacturer as a menstrual disc steriliser, so disc users should choose a device specifically intended for menstrual discs rather than assuming that a disc will be compatible simply because it fits.
Hello Caddy and Steriliser
The Hello Caddy is designed specifically for the Hello Disc and functions as both a carry case and microwave steam container. The Caddy is designed specifically for shape of the Hello Disc.
Plug-in steam sterilisers
Plug-in steam sterilisers have their own heating element, so you do not need a saucepan or microwave. They are generally best suited to home use and may appeal if you want a dedicated appliance with an automatic cycle.
Period Shop Menstrual Cup and Disc Steam Steriliser
The Period Shop Menstrual Cup and Disc Steam Steriliser is a dedicated steam appliance intended for cups and discs that fit within its internal chamber.
It includes an Australian power cable and automatic shut-off. Compare the internal chamber measurements with your cup or disc before purchasing, particularly if you use a wider menstrual disc.
Hello Steamy Menstrual Cup and Disc Steam Steriliser
The Hello Steamy has a slightly wider internal chamber than the Period Shop steam steriliser and is designed for both menstrual cups and discs.
Not every product will fit. In particular, the Hello Cup High Cervix Large is not compatible with the Hello Steamy, which is a useful reminder to check actual internal dimensions rather than assuming a device labelled for cups will fit every cup.
Portable UV steriliser
A UV device does not require boiling water or steam, which can make it convenient for travel. However, UV does not clean the product. Wash your cup or disc first.
The cup or disc should also be completely dry when the device instructions require it and positioned so that the intended surfaces are exposed to the UV light.
UV effectiveness depends on the device, exposure time and positioning. Folds, shadows and obstructed areas may receive less exposure, so do not assume that a short UV cycle is equivalent to boiling or steam.
Compact Travel UV Steriliser for Menstrual Cups and Discs
The Compact Travel UV Steriliser is a rechargeable device with enclosed UV-C LEDs and a collapsible silicone dome.
This may suit someone who wants a compact, water-free device for travel, but its chamber is narrow. Check both the product measurements and the required positioning before choosing it.
The cup or disc must be cleaned first and completely dried where instructed before being placed inside.
Boiling water
If your cup or disc manufacturer permits boiling, you may not need a dedicated steriliser at all.
Boiling is often the simplest and least expensive between-cycle sanitising method. Some people prefer to keep a dedicated saucepan for their reusable period products, although this is a personal preference rather than a requirement unless specified by the manufacturer.
Follow your product's instructions for water temperature, boiling time and positioning. Do not assume that every reusable cup or disc can be boiled.
When boiling is permitted, make sure there is enough water to prevent the product from sitting against a dry or overheated base of the saucepan. Follow any manufacturer instructions about keeping the product away from direct contact with the pan.
Do you need a dedicated menstrual cup or disc steriliser?
No. A dedicated device is optional.
Many reusable cup and disc manufacturers recommend boiling as part of between-cycle care, provided the product is suitable for boiling and the instructions are followed.
A purpose-designed device may simply make your routine more convenient, private or portable. It may be useful if you:
- live in shared accommodation
- prefer not to use a household saucepan
- travel frequently
- do not have reliable access to a cooktop
- want a dedicated appliance with an automatic cycle
- prefer a compact container that can double as storage
The best choice is the one that suits both your product and your routine. You do not need extra equipment simply because you use a reusable cup or disc.
Safe cleaning and sanitising basics
During your period, clean your cup or disc between uses according to the manufacturer's instructions. Wash and dry your hands before handling it and use clean water and a suitable cleanser where directed.
The Therapeutic Goods Administration's guidance for menstrual cups requires product information to explain cleaning before use and between uses and to state that menstrual cups are not supplied sterile. Menstrual disc users should follow the instructions provided with their particular product.
- Follow the instructions for both your reusable period product and the sanitising device.
- Clean the product before sanitising it.
- Do not assume every cup or disc can be boiled, microwaved or exposed to UV.
- Do not allow a cup or disc to sit directly against the base of a hot saucepan unless its instructions specifically permit this.
- Use the stated water level, cycle time and microwave wattage.
- Never microwave a steam steriliser without the specified amount of water.
- Take care around boiling water, hot surfaces and escaping steam.
- Allow steam containers and devices to cool before handling.
- Open hot lids away from your face and hands.
- Use a UV device only with a clean, dry product when instructed and position it exactly as directed.
- Allow your cup or disc to dry and store it according to the manufacturer's instructions.
The quickest way to choose
- Want the simplest option without buying another device? Check whether your cup or disc can be boiled.
- Want a compact microwave option? Compare the SteriPod, Saalt Compact Sanitiser, Ruby Steriliser and Hello Caddy, paying particular attention to compatibility and internal dimensions.
- Use a Hello Disc and want one container for storage and microwave sanitising? Consider the Hello Caddy.
- Want a dedicated appliance for home? Compare the Period Shop Steam Steriliser and Hello Steamy.
- Want a water-free travel option? Consider the Compact Travel UV Steriliser, provided your product fits and its care instructions permit the method.
Whichever option you choose, begin with two questions:
1. Is this method suitable for my cup or disc?
2. Will my product fit inside and be positioned correctly?
