Download OS X through the Apple Store (assuming you have a licence for it) and transfer to a USB key (think you need an 8Gb one) and install of that. It's dead easy. This may help: https://www.macrumors.com/2012/07/25/create-a-bootable-mountain-lion-usb-key-installer/
If it's a 2011+ MacBook Air, they don't come with reinstall discs/drives anymore.
Check out the "Internet Recovery" paragraph in the option below:

To make it super easy if you don't want to do internet recovery:

plus an 8gb flash disk.
Assuming there is a copy of the original installation image somewhere on the HD. With ML, unless u take the extra step to make a copy of it, ML install automatically deletes the installer after completion.
hm i just did a complete recovery, i downloaded lion and installed it, but everything looks the same, all the settings from the old user is still there.
How can i make it so its like when you buy it brand new?

OK u suppose to...
(1) Download but NOT install.
(2) U create a bootable external HD or flash with the installer in it and boot from that.
(3) U then use disk utility to ERASE your internal HD. That cleans it up.
(4) THEN you run the installer.

You would have to erase your drive and reinstall the operating system fresh. You can do it through disk utility.

It sounds like you just reinstalled without formatting the drive. Do this.
Hold command-r when booting to get to the Recovery HD partition. Once that loads start Disk Utility and select Macintosh HD on the left then erase the partition. Then quit Disk Util and proceed with the install. It will take a bit as the OS will need to DLL from Apple's servers.
This will give you a fresh install like out of the box.
