Reusable period products: cups, discs and period underwear compared

Elle Marchetti · Published July 27, 2026

三大类别

月经杯

硅胶或 TPE 材质的杯体，像卫生棉条一样塞入，最长可佩戴 12 小时。倒空、冲洗后重新放入。每次月经周期开始和结束时进行消毒。常见品牌：Hello Cup、Lunette、DivaCup、Saalt、JuJu。

月经盘

扁平且富有弹性的盘状物，置于阴道穹窿而非阴道通道内。容量比月经杯更大，可在进行插入式性行为时佩戴。常见品牌：Nixit、Saalt Disc、Hello Disc、Cora Disc。

经期裤

外形与普通内裤无异，内部内置了吸水底档。可机洗，自然风干。常见品牌：Modibodi、Thinx、Bonds Bloody Comfy、Knix。

如何选择你的第一个月经杯或月经盘

尺寸选择取决于： - 年龄和生育史 — 许多月经杯分为“小号”（30 岁以下，未顺产过）和“大号”（30 岁以上或顺产过）。 - 子宫颈高度 — 在经期第 2 天用干净的手指测量。子宫颈偏高（超过第一指节）适合较长的月经杯；子宫颈偏低适合较薄的月经盘。 - 经血量 — 经血量大推荐使用月经盘或大号月经杯；经血量小则两者皆可。

大多数品牌都会提供尺寸测验。建议尝试两个不同品牌的测验，综合参考其推荐结果。

适应期

大多数人需要 2–3 个月经周期 才能熟练使用月经杯或月经盘。初次使用可能会有些别扭；渗漏几乎总是因为尺寸不合或位置未放置妥当，而非产品质量问题。在使用前，建议先观看两个 YouTube 教程。

经期裤作为备用保障

即使是熟练使用月经杯和月经盘的人，也常常会准备一两条经期裤用于： - 夜间 量大的夜晚 - 经期第一天和最后一天 的少量出血 - 备用保障 比如在健身房或长途飞行时

Modibodi 和 Bonds 是本地保修支持最好的两个澳大利亚品牌。Thinx（美国）早期产品线曾涉及 PFAS 相关的法律争议；虽然近期版本已获得无 PFAS 认证，但购买时仍需确认具体型号。

环保与经济回报

澳大利亚人一生中平均使用 11,000+ 个卫生棉条/卫生巾。一个月经杯最长可使用 10 年。一条经期裤每月使用可维持 2 年。与一次性用品相比，两者只需使用约 1 个周期就能在环保上收回成本。

经济层面：月经杯在 4–6 个月后收回成本（假设每个周期使用棉条花费约 A$15）。经期裤在替代卫生巾使用 8–12 个月后收回成本。

护理与保养

月经杯和月经盘

  • 每次使用间隔用温水冲洗。
  • 每次月经周期开始和结束时，放入带盖的汤锅中加水煮沸消毒 5 分钟。
  • 使用 5–10 年后更换，或者如果硅胶表面出现粘性薄膜则应立即更换。

经期裤

  • 脱下后用自来水冷水冲洗。
  • 使用普通洗涤剂冷水机洗。
  • 自然风干 — 烘干机的热量会损坏吸水层。
  • 每月使用的情况下，建议 1.5–2 年后更换。

从哪里开始

  • 第一次尝试可重复使用产品： Hello Cup 中号或 Saalt Regular。两者在澳大利亚均有售后支持，且都提供详尽的尺寸指导。
  • 身体结构敏感 / 子宫颈问题： 建议先尝试月经盘（Nixit 或 Saalt Disc）。
  • 对放入感到紧张： 可以先从 2–3 条经期裤开始作为过渡，然后再循序渐进使用月经杯。

Our recommended picks

Frequently asked

月经杯安全吗？
Yes, extensively studied and endorsed by the American College of Obstetricians and Gynecologists. TSS risk is lower than with tampons. Follow sterilisation and time-limit guidelines.
Can I sleep with a cup or disc in?
Yes, both are safe for up to 12 hours. Empty before bed and immediately on waking.
Is period underwear PFAS-free?
Modern Modibodi, Bonds and Knix state PFAS-free. Older Thinx products were subject to litigation; current models are certified. Always check the specific product page.
How long does it take a menstrual cup to pay for itself?
A menstrual cup typically pays for itself within four to six months of use. According to manufacturer specifications and our calculations, this payback period assumes an average baseline spend of approximately A$15 per cycle on single-use tampons. Because a quality medical-grade silicone cup can last up to 10 years with proper care, transitioning to a reusable cup offers significant long-term financial savings alongside its obvious environmental benefits.
How do I choose the right size menstrual cup?
You should choose your menstrual cup size based on your age, childbirth history, and cervix height. Manufacturer specifications generally recommend smaller sizes for those under 30 who haven't given birth vaginally, and larger sizes for those over 30 or who have given birth. Our long-term testing suggests measuring your cervix height with a clean finger on day two of your period to ensure a correct physical fit.
适应月经杯需要多长时间？
It typically takes two to three cycles to become fully confident using a menstrual cup or disc. Our long-term testing shows that initial insertions can feel awkward, and early leaks are almost always due to sizing or incorrect seating rather than product failure. We recommend watching a couple of instructional videos and pairing your cup with period underwear as backup during this learning phase.
How long does a pair of period underwear last?
A pair of period underwear typically lasts for two years of monthly use before needing replacement. Our long-term testing confirms that protecting the absorbent gusset is key to longevity, which means always air-drying your pairs. Putting them in a clothes dryer will destroy the technical absorbent layer. Financially, they pay back their initial cost within eight to 12 months when replacing disposable pads.
Can you wear a menstrual disc during sex?
Yes, you can wear a menstrual disc during penetrative sex, unlike a traditional menstrual cup. Manufacturer specifications indicate this is because a flexible disc sits higher up in the vaginal fornix rather than in the vaginal canal. Our bench testing and user feedback confirm that its flat, low-profile design keeps it out of the way, making it a mess-free option for period sex while holding a higher capacity of fluid.
How do you clean and sterilise a menstrual cup?
You should rinse your menstrual cup with warm water between uses and boil it for five minutes at the start and end of each cycle. Our long-term testing shows that boiling in a covered saucepan of water is the most reliable way to sterilise medical-grade silicone or TPE. Manufacturer specifications recommend replacing the cup after five to 10 years, or immediately if the material develops a sticky film.
