Quick Detail:

Thank you for your trust. You have browsed through our company's products
This product is a reproducible bacterial filter, model 4-070305-00
Based on its performance (efficiency, resistance, dust holding capacity), this product is classified as a filter.

Repeatable bacterial filters are consumables used in conjunction with ventilators, anesthesia machines, and artificial respirators. They are mainly used to filter bacteria, particles, and increase the humidity level of gases in the tubing of ventilators and anesthesia machines (insulation and moisturization). They are also used in conjunction with lung function testing equipment.

According to relevant regulations, filters can be divided into six categories: coarse efficiency, medium efficiency, sub high efficiency, and ultra-high efficiency, and this product belongs to the category of repeatable high-efficiency filters. The efficiency testing method for filters varies depending on the efficiency of bacterial filters. Therefore, when using a filter, it is not only important to understand its filtering efficiency, but also to know the testing method

The antibacterial efficiency of coarse, medium, and high efficiency test filters for general ventilation:
(1) Weighing method: There are artificial dust weighing method and atmospheric dust weighing method. This method originated in the United States and is popular, often used for efficiency testing of coarse filters.
(2) Colorimetric method: originated in the United States, commonly used for efficiency testing of medium efficiency filters.
(3) Artificial dust counting method: widely used in Europe, will replace colorimetric method for medium efficiency testing.
