What is the difference between a waterproof anti-mite mattress protector and a regular mattress protector?

May 13, 2025

1. Product function difference
The Waterproof Anti-mite Mattress Protector uses a TPU polymer waterproof membrane or a multi-layer composite structure to achieve liquid barrier, and even 300 ml of liquid can be splashed to avoid penetration. Ordinary protective covers can only prevent water splashing, and long-term immersion will still penetrate into the mattress. In addition, the waterproof anti-mite model inhibits the breeding of mites through high-density weaving or antibacterial coating, and the mite blocking rate can reach more than 99%, while the ordinary model does not have this function.
The waterproof anti-mite protective cover adopts micron-level air permeable hole technology to keep air circulation while waterproofing to avoid stuffiness; ordinary protective covers (especially chemical fiber materials) are prone to sweat accumulation due to airtightness, which accelerates bacterial reproduction.

2. Material and process comparison
The waterproof anti-mite model is usually designed with more than four layers: surface layer (Tencel/bamboo fiber) → anti-mite layer → waterproof membrane (TPU) → bottom layer (anti-slip cotton cloth). Ordinary models are mostly single-layer cotton or polyester fibers without special treatment. Waterproof and anti-mite models often add natural antibacterial materials such as nano-silver ions and bamboo fibers, with an antibacterial rate of more than 90%; while ordinary models are prone to mold due to moisture, and may produce odors after long-term use.

3. Applicable scenarios and people
Allergic constitution: Waterproof and anti-mite models reduce dust mite contact through physical barriers and reduce allergic reactions (such as nasal congestion and rash).
Children/pet families: The anti-urine penetration function (such as the Chunshan Youcan model) can cope with sudden liquid pollution, and ordinary models cannot resist such risks.
Humid areas: The moisture-proof effect is significant during the rainy season to prevent mildew inside the mattress.
