Description
Product Overview
PEUTIER synthetic filter paper stickers are precision-engineered filtration solutions designed for mushroom cultivation and laboratory applications. Each disc measures approximately 84mm (3.3 inches) in diameter with 0.3 µm filtration capability, perfectly fitting standard 90mm jar lids. The filter material consists of expanded polytetrafluoroethylene (EPTFE), known for exceptional heat resistance and pressure tolerance. Each package contains 50 pieces of adhesive-backed filter discs, providing ample supply for ongoing cultivation projects or laboratory work. The blue protective film ensures adhesive integrity until application, while the consistent 4.9-star customer rating reflects reliable performance across various growing environments.

Usage
These filter paper stickers serve critical functions in controlled cultivation environments where proper gas exchange and contamination prevention are essential. Home mushroom cultivation enthusiasts will find them indispensable for maintaining optimal growing conditions in mason jars and similar containers. Laboratory technicians utilize them in bottletop filtration systems for various scientific applications. The stickers create breathable barriers that allow necessary air exchange while blocking contaminants and spores. Application involves simple peeling from the protective film and pressing firmly onto cleaned jar lid holes before closing containers. This process ensures secure adhesion and consistent performance throughout the cultivation cycle.

FAQ
What materials are these filter paper stickers made from?
The filters are constructed from expanded polytetrafluoroethylene (EPTFE), a synthetic material known for excellent chemical resistance, temperature stability, and consistent filtration performance. This material choice ensures the filters maintain their structural integrity and filtration capabilities even when exposed to moisture and varying temperature conditions common in cultivation environments.
How do I properly apply the filter stickers to jar lids?
Begin by cleaning the jar lid surface to remove any dust or debris. Peel the filter disc from the blue protective film, align it over the lid hole, and press firmly around the edges. Ensure complete contact between the adhesive and lid surface before closing the container. The adhesive is designed to create an airtight seal while maintaining filtration functionality.
Can these filters be reused after sterilization?
While the filters demonstrate good heat resistance, they are designed as single-use components for optimal performance. Attempting to sterilize and reuse them may compromise the adhesive integrity and filtration efficiency. For consistent results, we recommend using fresh filters for each new cultivation cycle or filtration application.
What is the shelf life of unopened filter paper stickers?
When stored in their original packaging away from direct sunlight and extreme temperatures, the filters maintain their performance characteristics for approximately two years. The adhesive properties and filtration capabilities remain stable throughout this period when stored under normal indoor conditions.
Are these filters suitable for laboratory use beyond mushroom cultivation?
Yes, the 0.3 µm filtration capability and EPTFE material composition make them appropriate for various laboratory applications including sample filtration, air exchange in culture containers, and other processes requiring reliable micron-level filtration. Their compatibility with standard bottletop filter holders expands their utility across different scientific contexts.
