Nasaleze PM Shield is clinically proven to provide fast and effective protection against harmful PM particles. The application of Nasaleze PM Shield allows the creation of a barrier in the form of a gel on the surface of the airways. That barrier traps harmful PM particles that are inhaled through the air. PM particles cannot be seen with the naked eye, they are odorless and tasteless, but these particles, especially the smaller ones (PM10 and smaller), can be very harmful to human health. Acting as a barrier, Nasaleze PM Shield protects the body from the harmful effects of PM particles contained in the air. PM particles can be composed of hundreds of different chemicals, come in different sizes and contain a mixture of: smoke, smog, dust, pollen and aerosols. Since they cannot be seen, smelled and tasted - they represent a hidden health hazard. The biggest health problems are caused by the smallest PM particles (PM10 and smaller), which are inhaled into the lungs. Smaller PM particles, with a diameter of less than 2.5 micrometers (PM2.5), are even more dangerous because they are inhaled even deeper into the lungs, they enter the bloodstream and spread throughout the body, damaging vital organs such as the lungs, heart and brain. .How to apply Nasaleze: In 5 steps Step 1 – empty your nose.
