Carbon filter HELP UK

Hi, I was just about to order my tent and cf kit which come in a package. After reading.. I found out that people were saying not to buy the cheapo carbon filters as they dont hide the smell properly etc. So now I'm wondering if i should the buy the CF separately. Here is a link to the kit I was about to order

http://www.ebay.co.uk/itm/230860590...l?_sacat=0&_from=R40&_nkw=230860590413&_rdc=1

the tent is 90x90x160 so I don't want to spend hundreds on a carbon filter kit. Preferably 100 or 120 if I really really have to.

Thanks
