In a statement, ZERO says that changing filters "is announced with impunity through the Internet" by workshops that charge between 300 and 500 euros, which is cheaper than maintaining or replacing the filter, which can cost more than a thousand euros.
Inspection centers do not have equipment capable of detecting "particulate filter-related infringement and fraud", which remains unpunished.
Drivers' complaints about fuel consumption, mechanical problems and the high cost of filter maintenance lead many to seek "alternative solutions, such as particle filter removal and readjustment of all electronic functions" associated with them, so that vehicles compulsory periodic inspections, describes ZERO.
The association argues that "it does not make sense to inspect current vehicles based on emission criteria that are more than 20 years old," arguing that it tightens the emission opacity limit allowed for cars made after 2009.
The latest diesel engines emit smaller particulate pollutants that "escape the sensitivity limit of the opacimeter, even though they may be present in high concentrations, making it difficult to identify illegalities."
Inhaled by humans, these smaller particles are not filtered and cause respiratory problems, and may be related to nasal and airway irritation, which is aggravated when "they reach the lungs in depth and pass into the bloodstream, causing and / or aggravating respiratory and cardiovascular diseases, and even lung cancer.
