COSMO vs FIREGAS Hood Comparison
Airflow Power
The FIREGAS insert delivers a robust 600 CFM of airflow, making it suitable for high-heat cooking and efficient removal of oil fumes. The COSMO Delta does not list a specific CFM rating in its published specifications. While the COSMO offers efficient filtration, the FIREGAS provides a measurable airflow metric that suggests stronger ventilation capacity for heavier cooking tasks. If you prioritize raw suction power, the FIREGAS specification is the clear choice here.
Noise Level
On noise performance, the COSMO Delta claims a quiet operation of 40 dB on its lowest fan speed under optimal conditions with rigid ducting. The FIREGAS specifies that its noise level remains under 57 dB at high speed. The COSMO appears quieter on its lowest setting, while the FIREGAS provides a maximum threshold. You get different noise profiles depending on your usage. The COSMO is likely quieter for gentle ventilation, while the FIREGAS offers a high-speed cap.
Installation Type
These units serve different kitchen layouts. The COSMO Delta is an under-cabinet hood with a slim profile, designed to fit beneath standard cabinets and save space. The FIREGAS is a built-in insert hood, intended for installation inside cabinetry or islands. You must choose based on your existing kitchen structure. If you have open shelving or standard upper cabinets, the COSMO fits. If you are remodeling with enclosed cabinetry, the FIREGAS insert is the appropriate choice.
Filter Material
Filtration quality varies by material. The COSMO uses durable reusable aluminum mesh filters to trap grease and oil. The FIREGAS includes stainless steel baffle filters that are dishwasher-safe and removable. Stainless steel baffle filters generally offer better grease separation than mesh filters. The FIREGAS filters are also explicitly noted as dishwasher-safe, which may simplify cleaning. If you prefer easy maintenance and superior grease capture, the FIREGAS stainless steel baffle filters have the advantage.
Dimensions
Physical size impacts fit. The COSMO Delta measures 29.5 inches wide, 18.8 inches deep, and 5.3 inches high. The FIREGAS insert is 27.8 inches wide, 11.5 inches deep, and 10.3 inches high. The COSMO is significantly slimmer in height and deeper, fitting under cabinets. The FIREGAS is narrower and shallower but taller, designed for internal cabinet mounting. You need to measure your specific space carefully, as their footprints and heights are quite different.
