High-Temperature Resistant High-Efficiency Filter is designed for cleanroom HVAC systems, drying rooms, sterilization areas, coating lines, ovens and other controlled environments that require high-efficiency air filtration under high-temperature conditions.

In cleanroom projects, normal filters may deform, lose efficiency or become unstable when exposed to high temperature. This filter helps solve problems such as particle contamination, unstable airflow, filter damage and frequent replacement in high-temperature clean air processes.

The filter uses high-temperature resistant materials and high-efficiency filter media to provide reliable particle removal and stable performance. It is suitable for cleanroom areas that require both high cleanliness and heat resistance.

Main Features:
- High-temperature resistant high-efficiency filter

How Does a Hand Shower Filter Work?

Water from your pipe enters the filter canister, which is filled with various filtration media. As the water passes through these media, contaminants are reduced or removed through processes like:

Adsorption: Contaminants stick to the surface of the filter media (e.g., activated carbon).

Redox (Reduction-Oxidation): A chemical reaction where media like KDF changes contaminants into harmless substances (e.g., chlorine into chloride).

Mechanical Filtration: Filtering out sediments and large particles through a physical barrier.

The cleaned water then exits the filter and flows through your hand showerhead.

Parchment Paper

Food-grade parchment paper, also known as baking paper, is a versatile kitchen essential designed for direct contact with food, widely used in home baking and commercial food production. It stands out for its heat resistance, non-stick performance, and food safety compliance.

Food-grade parchment paper, also known as baking paper, is a versatile kitchen essential designed for direct contact with food, widely used in home baking and commercial food production. It stands out for its heat resistance, non-stick performance, and food safety compliance.

Parchment paper is not made from animal sheepskin. Instead, it is based on plant fiber paper. The mainstream type is silicone-coated paper (for food use), and there are also a few that are sulfurized-treated paper, all of which meet food contact safety standards.

The core raw material of high-quality food-grade parchment paper is 100% virgin wood pulp. Unlike ordinary paper, it undergoes a special coating process using food-grade silicone a key component that delivers the productâ??s signature non-stick property.
