6. The particle filter I bought does not work properly. What should I do?

Please, send us an email as soon as possible to [e-mail] with all this information:

• A picture of the technical data sheet of the car. Identification number must be clear.
• A gas analysis.
• The Kat Europe invoice.
• The filter guarantee form. Please, specify all the technical data.
• The guaranty form.

The guarantee process cannot be started before receiving all the technical data.

The guarantee period will be that granted by the manufacturer for each product marketed by KatEurope, which will usually be two years. The guarantee period for each product will be indicated on the purchase invoice and this will be necessary for processing the guarantee.

To minimise these deadlines and return costs, you can send us photographs of the product showing the fault clearly and in detail, along with the guarantee form. If these photographs are sufficient to evaluate the product guarantee, the product will not need to be returned. After receiving the form and photos, the opinion will be communicated within 10 days and, if the guarantee is accepted, the amount will be refunded by the same method used for the purchase within a period of 15 days from the communication of the resolution.
