Available in three sizes: small, medium, and large, they all come with an optional speaking diaphragm to help provide easier communication. 3M™ Secure Click™ HF 800 Series Half Mask Reusable Respirator helps protect against particulates and a wide variety of gases and vapours when used with approved 3M™ Secure Click™ cartridges and filters.

Breathability: Greater breathability and comfort provided by the world’s first quad flow cartridge system. Two dual flow cartridges on each respirator combine to create four airflow paths for easier breathing.

Simplicity: The new 3M™ Secure Click™ Series features a quick, simple cartridge/filter connection. It works just like a seat belt. Simply align the connections and push until you hear a click and feel confident that filters and cartridges are installed properly. Quick, easy, one touch user seal check helps provide improved confidence in respirator fit.

Comfort: Designed with smart, intuitive features, this respirator helps provide comfort without compromise. Silicone face seal with patented flex joint nose bridge helps provide a softer feel for more comfort on the wearer’s face. Easy adjust head cradle buckles – pull straps to tighten, squeeze the buckles to loosen. Exhalation valve helps direct exhaled breath and moisture downward. Advanced silicone material for increased comfort and greater durability.

This half mask respirator may be used with 3M™ Secure Click™ Cartridges D8000 Series and Filters D3000 Series and D7000 Series against a variety of gases, vapours, and particulate hazards according to EN approvals. Breathing hazardous levels of particles, gases and vapours can be harmful to your health. 3M™ Secure Click™ Half Mask Reusable Respirator can help reduce exposure to many contaminants when properly fitted and used with approved 3M™ Secure Click™ cartridges and filters.

Cleaning and Storage

Cleaning is recommended after each use. To clean the respirator, the 3M™ 105 Wipe should be used to wipe the face seal of the product. Remove filters. The head harness assembly, exhalation valve, inhalation valve and speaking diaphragm (if present) can also be disassembled if necessary.

Alternatively, clean parts (excluding filters) by immersing in warm cleaning solution (water temperature not to exceed 50 °C), scrub with soft brush until clean. Add neutral detergent if necessary. Disinfect respirator by soaking in a solution of quaternary ammonia disinfectant or sodium hypochlorite (30 ml/7.5 l) or other disinfectant. Rinse in clean, warm water and air dry at room temperature in a non-contaminated atmosphere. Do not reassemble parts until facepiece is completely dry.

A respirator washer can be used to clean the HF-800 Series respirator. Respirator washers have a rack designed to hold the respirator in place during washing. DO NOT use a washing machine, which allows the respirators to tumble while being washed. This could damage the respirator. Water temperature should not exceed 50°C.

When to change the filters

Respirator filters do not last forever. Once a gas and vapour filter has been used to its full capacity, it will no longer offer any protection. An overused particulate filter will still protect you, but it will be hard to breathe through, leading to fatigue and reduced productivity.

The service life of a filter can be affected by a number of factors, including the type of filter, the concentration of contaminants in the air, breathing rates, humidity and temperature. Best practice is to establish a filter change schedule – a specified time period after which filters will be replaced. This time period is best set by using objective data and a service life estimate tool, such as the 3M Service Life Software. Alternatively, a filter change out schedule can be developed by considering typical breakthrough times for gas and vapour filters, or clogging times for particulate filters, in your workplace, and applying a safety margin. However, this method is less accurate as it relies on human senses which are both subjective and variable.

As a very minimum, filters must be changed when:

· You can taste or smell the contaminant when wearing the respirator correctly (gas and vapour or combination filters)

· The filter becomes difficult to breathe through (particulate or combination filters)

· The expiry date of the filter has passed

· The filter has been out of its packaging for 6 months or more (gas and vapour or combination filters)

· The filter shows any signs of damage
