Hi Mr. Ayman
I wash the filter element every 10,000 to 15000 kms. I do this in my Daewoo lanos & in my dad's Nissan Sunny
I think you can do this 4 or 5 times then it is advisable to throw the element because the element could get cut & in that case dirt could come inside your engine while you are unaware of that & in that case some damage could happen - you can add 1 drop of downy to make the fabric soft & in that case you can at least double the age of the filter element.
The cleaning process takes 5 minutes & then you leave the element to dry over night but offcourse you have to seal the air filter withe the element embedded there the correct way
I hope I have clarified every thing
Thanks for your inquiry
