Best picks
The 09EX is the larger stated-coverage option; the 07EXN takes less space. Your choice depends on footprint, the maker's room guidance and ventilation.
Quick answer
Choose InstaChill 09EX if you want the larger model with manufacturer-stated coverage up to 15 m². The 07EXN is the compact alternative, with the brand stating coverage up to 10 m² and a 7-litre tank. Both are evaporative coolers, so provide ventilation and temper expectations in humid weather.
