Kitchen Upgrade - Chimney

Hey Guys,

Need to my Chimney for my new modual Kitchen, planning to buy online. Please suggest some Reliable brands go for, also can someone please make me understand the basic specifications to look for and how to know the suitable size of chimney for your usecase.

Can you share the list of brands to totally avoid. I saw some negative post for Faber & Hindware and saw some people suggesting to go for Elica.
