Introducing 3M™ Secure Click ™ HF-803SD the worlds first 4-way airflow filter system used in a reusable half-mask respirator that offers simple, comfortable and offers effective protection. Protection against particulates and a range of gases and vapours is only possible when used with approved 3M™ Secure Click™ cartridges and filters. Suitable for a broad range of industrial applications, the innovative comfort features help to ensure that the respirator is worn consistently over long periods.

The 3M™ Secure Click ™ HF-803SD reusable respirator features an optional speaking diaphragm to help provide easier communication while you work. An adjustable head cradle helps fit a large variety of head sizes, with additional neck-straps for a more secure fitting. An exhalation valve that helps to direct exhaled breath and moisture downward to avoid fogging up glasses or face shields. A silicone face seal coupled with a patented flex joint nose bridge helps to provide a softer feel for more comfort whilst in use.

Filtered respirator facemasks are essential PPE for environments where particle ingress can be potentially hazardous to your health, such as gas, vapours or dust. They are often more suitable for heavy-duty tasks than disposable facemasks. Replaceable respirator particulate filters are graded in different ways to indicate their suitability for different applications, such as;

• A- Organic vapours with a boiling point more than 65°C
• B- Inorganic vapours
• E- Acid gases
• K- Ammonia and ammonia derivatives
• AX- Organic vapours with a boiling point less than 65°C

As particle filters load up with the contaminant they actually become a better filter. However, they become a harder filter to breathe through. The user will notice breathing becoming too hard and will then need to change the filter.

Depending on the health and safety requirements of your workplace or the demands of your application, you may need to choose between a half mask or full mask respiratory. Half mask respirators cover only the nose and mouth, while full masks cover the entire face. While both masks may have the same grade of filter, a full face mask has the benefit of sealing around the whole face, creating a more secure seal. Full face masks also have the advantage of protecting the eyes from vapours or splashing. As such, the full face mask option is often a better choice for potentially more hazardous conditions.

However, a half-mask might be a more cost-effective option if extra protection isn't needed, or might be more suitable for use in combination with specialized headgear.

When it comes to respiratory protection, the correct fitting and testing of your respirator is just as important as selecting the correct respiratory protective equipment for your working conditions. Be sure to follow all pertinent instructions and that health and safety best practice is adhered to at all times. Always be sure to use the correct filters for your environment, and make sure the replacement filters are changed as regularly as is recommended.
