Secure Click™ HF-800 half mask, without filter, size M. The 4-path air flow filter system ensures easier breathing due to low breathing resistance. Unique, fast, and secure Secure Click™ filter connection. Seal check by pressing a button provides assurance that the mask fits tightly.

The 3M™ Secure Click™ HF-800 half mask series is designed to provide effective and comfortable protection against many widespread gases, vapours, and particulate matter found in industrial environments when used with the corresponding range of filters. The masks are available in three sizes and can be optionally equipped with a speaking diaphragm (HF-800SD) to facilitate communication while working.

Low breathing resistance: the world's first 4-path air flow filter system makes breathing easy and comfortable. Two dual air flow filters on the respirator merge to create four air flow paths to ensure ease of breathing.

Easy to use: the new 3M™ Secure Click™ series features a quick and easy filter connection. It works as simply as a seat belt. Just align the connections and engage them until you hear a click. You can then be confident that the filters and cartridges have been fitted properly. The quick and easy seal check by pressing a button provides assurance that the mask fits tightly. The optional speaking membrane is designed to make communication easier while working.

Comfort: the silicone face seal with its patented, flexible nose profile is soft and provides a comfortable feel for the mask wearer. The straps are easy to adjust and fit. The exhalation valve helps to conduct warmth and moisture from the breath downwards and out of the mask. This half mask series is used together with 3M™ Secure Click™ filters from the D8000 (gas/vapour filter), D3000 (particulate filter), and D7000 (particulate insert filter) series to provide protection from a wide range of gases, vapours, and particulate matter in accordance with EN approvals.
