Thanks for explaining in detail.
Budget is a constraint as I don't want to spent much .
My usage will be maximum an hour or 2 a day that too for just till feb-March.
Plus I need something very light weight too.
I am worried about the oxygen part but got be careful .
Thanks.
The model you suggested Bajaj one is same I ordered in features only difference is metal vs plastic.
I have read reviews and it says plastic one has hold very well too.
So both are more or less same.
Thanks again.
I will check local shop and see if I get it at that price.
The reason I am not looking at PTC heaters are I need a fan too. I understand the fan you say is not that powerful but if it is just about decent also. It should be okay for me.
