ERGONOMIC FEATURES
Check out the functionality and quality of ergonomic design and plan reflected in all of FREKA’s products.


'Complete protection from contaminants'
Insert is an ergonomically-structured mask accessary perfectly pressing against the face.
It helps maintaining comfortable breathing and acts like
a gas mask to prevent the inflow of harmful substances.

The valve helps breathing comfortably and release the exhaled humidity from inside the mask.





'High efficient filters with N95 performance'
FREKA’s four layered filter helps to ensure you breathe only the finest air. While one of our layers(MB Filter) protects against over 95% of PM2.5.

Activated Carbon Fibre layer removes most gaseous pollutants such as SO2, and NO2.

▶ 4 layers of high density nonwoven filters
▶ Electrostatic induction Melt-Browned filter
▶ ACF filter that collects harmful substances
▶ PP Frame to secure intake/exhaust space
