Thank you. The pollution in Bangalore and for that matter in India is
multiple times more than say Singapore (I am assuming that is where
you live). I cannot even dare to guess a number for the multiple here.
Especially the COx and NOx from the exhaust of the vehicles. You got
to experience to believe it. So if you are aiming at this market, it
is worthwhile to develop a DAC Cloth filter. And the other thing is a
velcro strap. Believe me it is so much easier with the velcro strap,
especially to get the tension right especially considering that the
tension is the core aspect of getting the one way valve effect right
with TOTOBOBO.

BTW I could not track the package using the tracking number given to
me, after the package left Singapore. Pretty much the Singapore post
office website does not have a visibility into the package once it
leaves Singapore. So if the cost permits I would urge rather you use
Fedex or UPS.

Cheers
Nagaraj
