Multipurpose mask - grass mowing masks, gardening masks, woodworking masks, military/tactical masks, and more! When you are working in a dusty or dirty environment, there is nothing to protect your lungs from what you are breathing in. While dusting, sweeping, cleaning out a basement or attic, or working with wood, the air we breathe can contain enormous amounts of spores, pollen, mold, plant fragments, human and pet dander, and many other airborne contaminants. When outdoors, especially when plants are blooming, the air can have a very high pollen count. Pollen can easily trigger an allergic reaction, ranging from the sniffles to severe inflammatory reactions. In the springtime, as well as the fall, pollen counts usually spike dramatically in many seasonal locations. While this usually only lasts for a month or so, the impact on pollen allergy sufferers can be dramatic. Staying indoors with the windows closed is a solution, but not a practical one for most. Medications may relieve the symptoms, and are highly effective for some, but masks actually help prevent the pollen from entering the respiratory system. Masks can make the outdoors bearable again during the "allergy" season or the "dry" season , when pollen and dust counts are high. Our bodies are designed to handle certain amounts of pollen or dust, but we need protection when we are faced with larger than normal amounts of dust and pollen, and for those of us who are allergic or have certain sensitivities to various other airborne particles.
