Many jobs today are associated with health hazards. Individuals involved in travel, mining, farming, painting, sandblasting, cement and concrete finishing, bricklaying, welding, working with iron, shipbuilding, or even allergy sufferers expose their lungs to an excessive amount of airborne threats. First Defense Nasal Screens™ are the portable, effective solution to breathing healthier, cleaner air.

First Defense Nasal Screens™ are not designed to replace the dust mask or respirator. Rather, it’s intended for those who can’t, or won’t wear a hot, uncomfortable face mask to filter breathable air.

Take a look at some areas where First Defense Nasal Screens™ are being used today!


With viruses traveling through our air on respiratory droplets sized 1 to 10 microns and the world dawning facial masks, shields, scarfs and other solutions for protection many are adding an additional layer with First Defense Nasal Screens. Through filtration tests First Defense Nasal Screens have been proven to reduce respiratory droplets from entering the nasal passages by up to 90% at 1 micron by totally sealing the nasal passage.  First Defense Nasal Screens can be comfortably worn under the masks and in conjunction with masks and other devices and when masks can not be worn, while eating, communicating or any other reason. So remember First Defense Nasal Screens  as a first layer or first defense to reduce the nasal inhalation of these dangerous if not deadly droplets. Let us help filter your life.


Unfortunately, there is no cure for allergies. Symptoms often last year-round and nasal allergies, which include hay fever, animal dander, dust mites, mold spores and pollen, can irritate people and cause sneezing, wheezing, runny nose, and itchy, watery, red eyes. As the first line of defense for nasal passages, First Defense Nasal Screens™ help make these allergens a more manageable part of life.


First Defense Nasal Screens™ work as a filter and reduces the amount of dispersed grass and dust particles a person might encounter while maintaining their lawn.


Emissions of dust and particles from construction, demolition and civil engineering sites have been shown to adversely affect the local environment and the overall health of on-site workers. First Defense Nasal Screens™ filter these particles and improves the quality of breathable air.


Millions of travelers fly through the air each and everyday exposing themselves to recycled air and contaminated air from neighboring sick passengers. While some airplanes have filters to clean this air, First Defense will greatly reduce your chance of breathing in contaminated air from your fellow nearby neighbor.
