Finally I get it after they sent back to the supplier, it takes 2 weeks to get here, I'm pretty amazed by how fast it gets to me, normally it would takes about a month or so, anyway thanks alot.
the description said this unit was suitable for room or office. when i opened the box it said it was a personal purifier. just what does that mean? i wanted a refund but was refused because i said the item was small which does not mean that it could be powerful. i have a bigger sized filter in my car vaccum
