LG 20L Convection Microwave Oven (MH2044DB) vs Blue Star Bottom Loading Water Dispenser (BWD3FMRGA)

What separates them

These two differ on 9 recorded specifications. The Blue Star Bottom Loading Water Dispenser (BWD3FMRGA) is ₹3,500 dearer. They are different kinds of product — convection microwave oven against bottom-loading water dispenser — so read the table as two spec sheets rather than a like-for-like.

LG 20L Convection Microwave Oven (MH2044DB)

₹9,490

A 20 litre convection microwave suits two to three people and can bake and grill as well as reheat. It fits a small cake tin but not a full roasting tray, so regular bakers should consider 28 litres or larger.

Who the LG 20L Convection Microwave Oven is for

Buy it if: Homes and small offices getting through a 20 litre bottle regularly who want both hot and genuinely cold water.

Avoid it if: Anyone who thinks this purifies water -- it does not filter anything at all.
