Product Description:

Our Absorbent Filter Paper is a premium product designed to meet the high-quality standards required for filtration purposes in medical and laboratory settings. This white absorbent filter paper is an essential component in HMEF (Heat and Moisture Exchange Filter) equipment, which is widely used in anesthesia and critical care for patient breathing systems. Thanks to its excellent filtration properties, it is also suitable for use in HME Viral filters, ensuring the highest level of protection against airborne pathogens.

With a precise pore size of 20 microns, our filter paper provides a perfect balance between permeability and retention capacity. This specific pore size is meticulously engineered to trap particles efficiently while allowing the passage of air and moisture. It makes the filter paper ideal for HME Filters, which are critical in preventing the passage of contaminants and ensuring the safety of both patients and healthcare providers.

Constructed from 70% wood pulp and 30% cotton pulp, the main material of our Absorbent Filter Paper is carefully chosen for its natural absorbency and strength. This blend ensures that the filter paper maintains its structural integrity even in high-humidity environments, which is crucial for its application in HME equipment where it must withstand the warm, moist conditions of exhaled breath. The wood pulp provides excellent absorbency, while the cotton pulp contributes to the overall durability of the filter paper.

At a weight of 90g/m2, this filter paper is neither too light nor too heavy. This weight ensures the filter is sturdy enough to handle the demands of continuous use, yet light enough to not impede airflow. This optimal weight contributes to the efficiency and effectiveness of the HME Viral filter, ensuring that patients receive the proper ventilation without any unnecessary resistance.

Quality and safety are our top priorities. The Absorbent Filter Paper adheres to the stringent safety standard GB/T18830-2009. This standard specifies the requirements for medical materials, ensuring that they are safe for use in healthcare settings. By complying with these standards, our product guarantees that it is free from harmful substances and is safe for its intended medical applications. This adherence to safety regulations provides peace of mind to healthcare providers, knowing that they are using a product that meets the necessary safety requirements.

Our Absorbent Filter Paper is the go-to choice for professionals who require reliable and efficient filtration. The white color of the filter paper gives it a clean and clinical appearance, which is consistent with the hygienic standards expected in medical environments. Whether it's used in HMEF Equipment, as an HME Viral filter, or as an HME Filter, our product delivers exceptional performance and reliability.

In summary, our Absorbent Filter Paper boasts a set of features that make it an indispensable component in medical filtration applications. Its 20-micron pore size for optimal filtration, a blend of 70% wood pulp and 30% cotton pulp for strength and absorbency, a suitable weight of 90g/m2 for ease of use, and compliance with the GB/T18830-2009 safety standard, all come together to create a product that is efficient, reliable, and safe.
