Guides

Chlorine is an acid gas, so P100 filters and organic-vapor cartridges won't protect you. This buyer's guide compares the best acid-gas and multi-gas cartridges for chlorine - 3M 60926, 3M 6006, 3M 6002, and the Honeywell North 75SCP100L - with water-treatment and pool scenarios, the color code, change-schedule.

The 3M 60923 covers organic vapor, acid gas, and P100 particulates. The 3M 60926 adds hydrogen fluoride (HF) and chlorine dioxide protection - required for semiconductor fabrication, glass etching, and chemical plants handling fluorine compounds.

The 3M 60921 provides organic vapor plus P100 particulate protection. The 3M 60923 adds acid gas protection for HCl, SO2, and Cl2 - critical for chemical processing and industrial cleaning environments. This guide compares protection levels, NIOSH approvals, and job-specific selection.
