How about LG Artcool series??? No one seemed to have commented on it. Besides looking good & a little more pricy, its electrostatic filter (named it Allerbuster, ionizer, plasmacluster, etc.) is very effective. According to air-con specialist shops, when Sharp's & Panasonic's electrostatic filter cease to function, then the entire air-con unit will not function, unlike LG's. Pls correct this statement if I'm wrong.
Also, electrostatic filters are consumables which requires replacement after every 2-3 yrs. It can be quite pricy to replace them at the moment.
