48Pcs EPTFE Synthetic Filter Paper Stickers – 20mm for Wide Mouth Jar Lids

Take your mushroom cultivation setup to the next level with these high-performance EPTFE synthetic filter paper stickers. Designed specifically for use under wide-mouth jar lids, each 20mm sticker features advanced expanded polytetrafluoroethylene (EPTFE) membrane technology — delivering a precise balance of waterproofing, breathability, and dust filtration that serious growers rely on. Made in Mainland China.

Why EPTFE Filter Stickers?

EPTFE is a next-generation waterproof and breathable material trusted across industries for its outstanding microporous structure. Each tiny pore (0.1–1.0 µm) is thousands of times smaller than a water droplet yet 700 times larger than a water vapor molecule — meaning moisture can escape as vapor while liquid water and contaminants are firmly blocked.

Key Features

  • Waterproof Protection: Micropores with diameters up to 10,000x smaller than water droplets prevent liquid from passing through, shielding your cultivation substrate from unwanted moisture and liquid erosion.
  • Breathable Gas Exchange: Allows fresh air and CO₂ to flow freely while keeping contaminants out — critical for healthy mycelium growth and fruiting.
  • Effective Dust & Contaminant Barrier: Dense, uniform micropore distribution forms a 3D network that stops dust, spores, and particulates from entering your jars.
  • Pressure Balancing: Equalizes internal and external air pressure, preventing pressure build-up or vacuum effects inside sealed cultivation jars.
  • Chemical & UV Resistance: Strong chemical inertness and UV resistance ensure long-lasting performance throughout your entire grow cycle.
  • Weather & Liquid Resistant: Withstands immersion and environmental exposure; quickly restores breathability after contact with water or oils.
  • Thin, Lightweight & Discreet: Easy to apply under jar lids without affecting the seal or fit — no tools required.
  • Easy to Clean: Resists corrosive contaminants and is easy to wipe clean, extending the service life of your cultivation lids.

Frequently Asked Questions

Q: What size jar lids are these 20mm EPTFE filter stickers compatible with?

A: These 20mm filter stickers are specifically sized for standard wide-mouth jar lids commonly used in mushroom cultivation, such as mason jar lids. Simply peel and apply them to the underside of your lid over a drilled hole (typically 15–18mm) for a secure, breathable seal.

Q: Do I need to drill a hole in my jar lid before applying these filter stickers?

A: Yes. For best results, drill a hole (approximately 15–18mm in diameter) in your jar lid, then apply the 20mm EPTFE sticker centered over the hole on the underside of the lid. The sticker's larger diameter creates a full, airtight seal around the hole while allowing gas exchange through the membrane.

Q: How many jar lids can I outfit with one sheet?

A: Each sheet contains 48 individual filter stickers, so you can prepare up to 48 jar lids per sheet — ideal for growers managing multiple cultivation batches at once.

Q: Are these filter stickers reusable?

A: These stickers are designed for single-use application per jar lid. The self-adhesive backing bonds to the lid surface during the sterilization and inoculation process. However, the EPTFE membrane is easy to clean and highly resistant to degradation, making it reliable for the entire grow cycle.
