Medicine has made great advances in the last 100 years with the introduction of antibiotics to combat bacterial infections but viral infections have been more difficult to manage. We have vaccines for Polio, measles, Mumps and Rubella and other pediatric viral illnesses but in regards to the common flu we are less successful. This is due to the viral coats of these viruses continually mutate and antibodies mounted against one flu strain is ineffective the next year when a new strain emerges.
Approximately 20 pathogens account for the overwhelming number of contagious respiratory infections. These are either bacteria or viruses which range in size form 0.08 to 1.1 microns. Spores and fungi are about 10 times larger. HEPA filters used in domestic heaters and coolers and overhead airline cabins trap particles larger than 0.3 microns.
Viruses are the smallest infectious particles, which are the agents that transmit the common cold and flues.
Viruses cannot survive for any length of time outside a living host and when free in the air they are quickly inactivated by ultraviolet sunlight, changes in moisture and a host of other environmental changes.
Each one of these droplets may carry many thousands of viral particles. These droplets vary in size from 1 to 5 microns and when expelled by a carrier person they can travel a distance from 3 to7 feet and infectious for several minutes before becoming inactivated by the environment.
Clearly, protection from inhaling these aerosolized viral particles should help mitigate contracting these illnesses. The CDC (Center for Disease Control) in
Atlanta has provided guidelines to protect the public such as frequent hand washing to protect hand mouth transmission from contaminated surfaces and avoidance of environments that are very crowded.
Nose Budz is designed to stop particles the size of the offending droplets (1 micron or larger) while maintaining sufficient airflow to allow normal breathing. It is worn discretely and comfortably for up to 12 hours.
The filter is a baffle filter, which is only engaged during inspiration and opens up during expiration that allows for respiratory moisture to be expelled during expiration. The cones that house the filters are made of hypoallergenic soft silicone, which accommodates to all nasal contours. A small nasal strap joins the 2cones allowing for easy removal.
