Respro is an outdoor sports brand born in the United Kingdom, with a history of more than 20 years, certified by the British Allergy Association.
 
The brand has eight product lines, all of which are models with replaceable cartridges, but not all models have smog prevention as their main function, so only the Sportsta and Techno series will be introduced.
 
Sportsta is a "sports model" launched by Respro, including the filter element, the price is close to 450 yuan, the filtration effect reaches the EU FFP1 standard, the filtration efficiency is only more than 80%, and it is not suitable for use in moderate and above air pollution environments. Although the model is available in three sizes, M, L and XL, its plastic mold and non-fitting filter element have a poor fit for Asian faces, further reducing its protective effect.
 
Compared to the Sportsta, the Techno meets the US N95 standard for better filtration, but also sacrifices some breathability. Despite the two exhalation valves, the Techno has a high breathing resistance and maintains a high temperature inside the hood, as the outer mold and filter completely cover the entire jaw, making it unsuitable for use in summer.
 
Respro's mask looks cool and fashionable, enhancing the charm of sports, which is an important reason why many users choose it. However, the brand's replaceable filter design brings a high leakage rate and mediocre particulate protection.
