I had been searching and comparing various purifiers online and then landed upon zerob purifiers site. I had heard these people had come up with a new purifier had seen the ad of theirs somewhere but then forgot the name.
Now when I searched on the net and found the site I came across that familiar name ECO and to my surprise they have started selling these online also. I bought one after taking a demo and now its working fine for last 3 months. no complaints. I remember having used their stuff tap purifiers long back.
