The breath clean airbrush nose filters consist of two units connected with a clip; this safety clip allows for easy removal. The units open the nostrils for natural breathing while filtering the unwanted pollutants. Each soft plastic disposable nose unit contains a filter. The white cellulose filter is used for dust, pollen and general pollutants, whilst the dual white and black filters contains cellulose and carbon, which reduced odours from Airbrush Tanning. Quantity:12 Breath Clean Nose Filters.
