COSMO COS-668A750 30 in. Vista Wall Mount Range Hood - Quiet 380 CFM

Our review of the COSMO COS-668A750 finds it best suited for homeowners who want a stylish, effective ducted range hood without a high-end price. The single biggest reason to buy is the combination of a stainless steel body with a tempered glass visor and a true 380 CFM airflow that removes cooking odors and smoke more effectively than typical recirculating microwave hoods. It balances performance, easy maintenance and energy-efficient lighting for midrange kitchens that need reliable venting to the outside.

Key Features

• Efficient Airflow: 380 CFM suction clears smoke and odors quickly so kitchens stay comfortable during heavy cooking.
• Ducted or Convertible: Designed as a ducted wall mount hood that vents outside, with a carbon filter kit available separately for ductless conversion.
• Permanent Filters: Heavy-duty stainless steel ARC-FLOW filters are dishwasher-safe for simple upkeep and long-term savings.
• LED Lighting: Built-in LED lights illuminate the cooktop area for safer and more accurate cooking tasks.
• Push Button Controls: A straightforward control panel provides three fan speeds and light control for easy operation.
• Compact Fit: 30 in. width and an adjustable chimney height fit common wall-mount installations in many kitchens.

Who It's For

This range hood is ideal for homeowners replacing a basic recirculating hood or over-the-range microwave who want a noticeable upgrade in airflow and aesthetics without custom fabrication. It suits 30 in. cooktops or smaller ranges and cooks who generate moderate to heavy smoke or strong odors.

It is less appropriate for households needing fully silent operation or professional-grade ventilation for large cooktops; the lowest measured noise can reach about 50 dB under optimal rigid ducting, and the unit ships with flexible ducting for easier installation which can affect noise and performance.

Pros & Cons

Pros

• Strong 380 CFM extraction that performs noticeably better than typical recirculating units.
• Durable stainless steel construction and a tempered glass visor that add a refined look to the kitchen.
• Dishwasher-safe permanent filters reduce ongoing maintenance costs and chores.
• Energy-efficient LED lights improve visibility without drawing much power.

Cons

• Installation can be mixed; some users report challenges with mounting the duct cover and the included flexible ducting may not match the quietness of rigid duct runs.
• Carbon filter for ductless conversion is sold separately if outside venting is not possible.
