Skip if
High-volume cooks on a 6-burner gas range will find 380 CFM short of what most ventilation guidelines recommend. If you regularly run multiple burners at full heat, a 600 CFM or higher unit is a better match.

Overview
The COSMO COS-30IRHP slots into the insert/built-in category at $252, a price that makes more sense for a COSMO product than for lesser-known brands. COSMO has built a substantial reputation in the mid-market range hood space, and the 1,500-review count at 4.2 stars is real market validation. At 27.8 inches wide and just 11.5 inches deep, it fits inside a standard 30-inch cabinet opening without protruding significantly.
The 380 CFM exhaust rating at 3 fan speeds is moderate. It is well-matched to a 4-burner electric range or a gas range used at moderate heat levels. The baffle filter captures grease effectively and is dishwasher-compatible, a meaningful maintenance advantage. At 193 watts the unit is economical to run. Push-button controls are simple and reliable for daily use.
At 15.9 pounds, installation is light for an insert hood, which helps with solo installation. The brushed stainless finish is neutral and pairs well with most kitchen lineups. For buyers looking for a trusted brand in the insert category without moving into the $400 to $600 range, this is a strong contender.
Pros
1,500 reviews at 4.2 stars provides well-established reliability data for an insert hood
COSMO brand has strong aftermarket support and parts availability
Baffle filter handles grease efficiently and cleans in a dishwasher
193 watts is economical for daily operation at 380 CFM
15.9 lb weight makes installation manageable with one person
Cons
380 CFM is modest and may underperform on a 4-6 burner gas range at full heat
27.8-inch width is slightly narrower than a full 30-inch range span
3 fan speeds only, which limits fine-tuning on high or low ends
Ducted exhaust only, so a duct run is required for installation

Performance notes
380 CFM at 3 fan speeds is appropriate for moderate-intensity cooking on an electric range or light to medium use on a 4-burner gas range. The baffle filter at 27.8 inches captures grease before it reaches the duct. At 193 watts the motor is quiet by design, and lower wattage motors tend to produce less mechanical noise. The 120-volt outlet requirement is standard for most residential kitchens. Dimensions of 11.5 x 27.8 x 11.4 inches fit a built-in cabinet space comfortably.
What buyers say
A 4.2 rating from 1,500 buyers is reliable market feedback. At this volume, the rating reflects a broad cross-section of real kitchens and cooking styles. Buyers generally praise COSMO's value-to-price ratio and find the insert format straightforward to install. Some buyers note the CFM feels adequate for everyday cooking but limited for heavy gas cooking, which is consistent with the 380 CFM spec.
The spec sheet lists this as a ducted exhaust-only hood. There is no ductless conversion listed for this model. If your kitchen cannot accommodate a duct run, COSMO makes other convertible models that may be a better fit.
Does the 27.8-inch width work over a 30-inch range?
As an insert hood, the 27.8-inch width is designed to fit inside a 30-inch cabinet opening, with the surrounding cabinet enclosure providing full coverage over the range below. Unlike an under-cabinet hood where width directly corresponds to coverage, insert hoods sit inside the cabinet so the cabinet itself provides the visual enclosure.
How does COSMO's support compare to larger brands?
COSMO has built a meaningful US market presence and maintains customer support channels with a track record of parts availability. With 1,500 reviews across this model alone, their hood lineup has proven durable enough for ongoing ownership over multiple years for a large number of buyers. They are not Broan-NuTone in terms of brand scale, but they are a well-established mid-market option.
