Can waterproof mattress protectors be used during menstruation?

May 13, 2025

Waterproof mattress protectors are highly applicable during women's menstrual period, and their core function is to block liquid penetration through a physical isolation layer. This type of product usually adopts a multi-layer composite structure, with a skin-friendly fabric (such as Tencel, bamboo fiber or high-density cotton) on the surface, a polymer waterproof membrane (such as TPU or polyurethane coating) in the middle layer, and a non-slip silicone particle or elastic edging structure on the bottom layer. When used at night during menstruation, the waterproof layer of the protector can effectively prevent blood from penetrating into the mattress. It can withstand 300 ml of liquid pouring without leakage. Some high-end models of waterproof membranes use micron-level hole technology to achieve the barrier function while maintaining breathability to prevent stuffiness during sleep.

Professionally designed menstrual protective mattress protectors will take into account the special properties of blood, such as adding anti-fouling treatment technology to the surface fabric to make blood stains easier to remove through regular washing. Some products will also inhibit the growth of pathogens through nano-silver ion coatings or antibacterial fibers to prevent health hazards caused by menstrual blood residues. For cases with heavy menstrual blood flow, it is recommended to choose a full-cover fitted sheet. Its 360-degree wrapping design can prevent side leakage from seeping into the gaps in the mattress from the edge. In actual use, it is necessary to pay attention to timely cleaning. Although the waterproof layer is washable, long-term residual blood stains on the surface fabric may affect the breathability and antibacterial effects. Compared with traditional disposable leak-proof pads, this type of reusable protective cover has more advantages in terms of environmental protection and economy. Calculated by washing twice a week, the service life can reach 3-5 years. Cases in hospital nursing scenarios show that the upgraded product with smart humidity sensors can also trigger an alarm when liquid penetration is detected, reminding you to replace it in time.
