You know that Blue Mask everyone wears? Did you know they are sprayed with teflon?  Teflon applied to a pan is relativley stable.  Only releasing fumes at high temperatures.  However, when applied to cloth, the same toxic fumes are released at much lower temperatures. As low as 150 to 185 degrees.  Your car heats up to as hot as 200 degrees.  So, if you keep and reuse your little blue mask day in and day out.  You could be consistently exposing yourself to toxic fumes which cause the Teflon Flu.

What is the Teflon Flu??

Polymer fume fever or fluoropolymer fever, also informally called Teflon flu, is an inhalation fever caused by the fumes released when polytetrafluoroethylene (PTFE, known under the trade name Teflon) reaches temperatures of 300 °C (572 °F) to 450 °C (842 °F) OR 150 to 185 degrees when applied to permeable cloth membranes.[1] (When applied to cloth membrane these fumes can be released when exposed to heat as low as 150 degrees) When PTFE is heated above 450 °C the pyrolysis products are different and inhalation may cause acute lung injury.[2] Symptoms are flu-like (chills, headaches and fevers) with chest tightness and mild cough. Onset occurs about 4 to 8 hours after exposure to the pyrolysis products of PTFE. A high white blood cell count may be seen and chest x-ray findings are usually minimal.

The polymer fumes are especially harmful to certain birds whose breathing, optimized for rapidity, allows toxins which are excluded by human lungs. Fumes from Teflon in very high heat are fatal to parrots,[3] as well as some other birds (PTFE toxicosis).[4]


Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The commonly known brand name of PTFE-based formulas is Teflon by Chemours,[2][promotional source?] a spin-off from DuPont, which originally discovered the compound in 1938.[2] Another popular brand name of PTFE is Syncolon by Synco Chemical Corporation.[3][promotional source?]

PTFE is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances wet PTFE, as fluorocarbons demonstrate mitigated London dispersion forces due to the high electronegativity of fluorine. PTFE has one of the lowest coefficients of friction of any solid.


PTFE is used as a non-stick coating for pans and other cookware. It is non-reactive, partly because of the strength of carbon–fluorine bonds, and so it is often used in containers and pipework for reactive and corrosive chemicals. Where used as a lubricant, PTFE reduces friction, wear, and energy consumption of machinery. It is commonly used as a graft material in surgical interventions. It is also frequently employed as coating on catheters; this interferes with the ability of bacteria and other infectious agents to adhere to catheters and cause hospital-acquired infections.
