![]() The maximum amount of certain gases or vapours that could be released into the air varies from one situation to another.īecause of this variation in (possible) concentrations, there are two classes of gas filters. Then look up which filter(s) to buy using the colour code. The colour code tells you which harmful gases and vapours the filter protects against.įor example, an ABEK filter with the colour code yellow protects against sulphur dioxide and hydrogen chloride, whereas orange means that the filter absorbs radioactive iodines.įirst, you need to find out which gases and vapours are or could be released in your company's workplace. Colour codesĮach gas filter has a specific colour code. In some gas filters, there is a chemical reaction which blocks the incoming gases and vapours. These protect against several types of gases, organic and inorganic vapours, sulphur dioxide and ammonia.Īn ABEK filter absorbs dangerous gases and vapours, enabling the user to breathe safely. And there are also multiple gas filters, such as ABEK filters. ![]() There are single gas filters which protect against one type of gas or vapour. What does an ABEK filter protect against? Gas filters must comply with the EN14387 standard (formerly EN141). As with all respiratory protection equipment, gas filters must also comply with European standards. Which gases and vapours a gas filter protects against depends on the type of filter. Some examples of these harmful substances are organic substances, such as sulphur dioxide, ammonia and mercury vapour. These gases and vapours can be present both inside and outside the workplace. Gas filters make sure that you do not inhale gases and vapours which have been or may be released during work. Only then can you be sure that you will be able to breathe safely and without any concerns in a (potentially) unsafe working environment.īut how to choose the correct gas filter? Gas filters: a must in the workplace However, it is very important that you always use the correct type of filter, e.g. 3M recommends replacing both pancake and cartridge filters within six months of opening their packages (PDF), or, in environments where oil aerosols are present, after only 40 hours of total use or 30 days after the first use, whichever comes first.When combined with a full-face or half-face mask, a gas filter provides excellent respiratory protection against hazardous vapours and gases. The cartridges are more expensive and weigh far more-8.6 ounces per pair on our scale-but they’re also sturdier, and they might be the better choice if you’ll be doing strenuous physical work, such as a kitchen demolition, while wearing your respirator. ![]() ![]() ![]() The pancake filters weigh just half an ounce per pair, and they’re our first recommendation for typical use outdoors and around the home. NIOSH approval means that, at the equivalent rating (P100 in this case), pancake-style filters, such as the 3M 2097 filter we recommend, protect you just as effectively as hard-plastic cartridge filters like the 3M 60926. And as P-designated filters, they also protect against oil-based substances in the air, such as paint fumes, as well as some caustic vapors. The “100” designation indicates that they capture 99.97% of fine particulates, such as wildfire smoke. P100-rated filters are the most widely available kind that meet that criterion. ![]()
