COSMO vs Zomagas Hood Specs
Installation Type
The COSMO Delta is designed as an under-cabinet range hood, featuring a slim profile that fits neatly below standard cabinetry. This makes it ideal for condos or apartments where overhead space is limited. In contrast, the Zomagas is a built-in insert hood. It is designed to be installed within a cabinet structure, requiring a specific cutout dimension of 26 inches wide by 10.2 inches deep. You must choose the installation style that matches your kitchen’s existing cabinetry layout, as these two models serve fundamentally different structural needs.
Airflow Power
Air movement capacity is a key differentiator here. The Zomagas insert boasts a maximum airflow of 600 CFM, providing strong suction to clear heavy cooking odors and smoke quickly. The COSMO Delta does not list a specific CFM rating in its published specifications. While it features a 3-speed motor, the lack of a stated airflow number makes it difficult to compare raw power directly. If you frequently sear or fry, the Zomagas offers a clear advantage in documented suction strength for faster air exchange.
Noise Level
Noise performance varies significantly between these two units. The COSMO Delta operates as quietly as 40 dB on its lowest fan speed when using rigid ducting under optimal conditions. This low decibel rating suggests it will be very unobtrusive during light cooking. The Zomagas has a maximum noise level of 65 dB. While this is comparable to a quiet park, it is substantially louder than the COSMO’s lowest setting. If a silent kitchen environment is your priority, the COSMO Delta is the quieter choice.
Filter Material
Both hoods use durable, washable filters, but the materials differ. The COSMO Delta includes reusable aluminum mesh filters that trap grease and oil effectively. These are simple to clean but may require more frequent hand washing to maintain clarity. The Zomagas features baffle filters made from #430 stainless steel. These are explicitly noted as dishwasher safe, offering greater convenience for maintenance. The stainless steel construction also provides good corrosion resistance, making the Zomagas filters more robust against long-term wear and easier to deep clean.
Physical Dimensions
The physical footprint of each hood impacts how it fits in your kitchen. The COSMO Delta is extremely slim, measuring only 5.3 inches in height and 18.8 inches in depth. This compact size is designed to save space under cabinets. The Zomagas insert is larger, with a height of 11.4 inches and a depth of 11.5 inches. It is wider at 27.8 inches compared to the COSMO’s 29.5 inches. The COSMO’s low profile is better for low-clearance areas, while the Zomagas requires more vertical space within your cabinetry.
Choose the Right Hood for Your Kitchen
Apartment dwellers with tight overhead space
The COSMO Delta features a slim 5.3-inch height and under-cabinet design, making it perfect for condos or apartments where vertical clearance is limited. Its quiet 40 dB operation on the lowest speed ensures minimal noise disturbance, while the reusable aluminum mesh filters provide effective grease capture without requiring frequent replacements.
Heavy cooks needing maximum airflow
The Zomagas insert delivers 600 CFM of suction power, handling heavy cooking smoke and odors more effectively than standard models. Its built-in installation allows it to fit seamlessly into cabinetry, and the 65 dB noise level remains manageable even at high speeds, ensuring your kitchen stays clear during intense meal preparation.
Users prioritizing easy filter maintenance
Zomagas includes #430 stainless steel baffle filters that are dishwasher safe, simplifying cleaning routines significantly. Unlike mesh filters that require hand washing, these durable baffle filters resist corrosion and can be safely placed in the dishwasher, saving you time and effort while maintaining hygiene and performance over the long term.

Frequently asked questions
Is the COSMO Delta or Zomagas better for low ceilings?
The COSMO Delta is the better choice for kitchens with low ceilings. It features a slim profile with a height of only 5.3 inches. This compact design fits neatly under standard cabinetry without encroaching on headroom. The Zomagas model is taller at 11.4 inches, which requires more vertical clearance. You should select the COSMO if saving space is your primary goal.
Which range hood is quieter, COSMO or Zomagas?
The COSMO Delta operates more quietly than the Zomagas model. It is specifically designed for small kitchens where low noise is a priority. The Zomagas unit provides 600 CFM of airflow, which typically generates more sound than the COSMO’s slim design. If you cook frequently and dislike loud ventilation, the COSMO Delta’s quieter performance will serve you better.
Does the Zomagas hood come in stainless steel?
Yes, the Zomagas 30-Inch Built-In Range Hood Insert is available in stainless steel. This finish offers a durable and classic look that suits many kitchen styles. The COSMO Delta, by contrast, comes in matte black. You can choose the Zomagas if you prefer a metallic finish over the dark aesthetic of the COSMO model.
How wide are these range hoods?
Both the COSMO Delta and the Zomagas model are designed for 30-inch installations. The COSMO Delta measures 29.5 inches in width, while the Zomagas insert is 27.8 inches wide. Both sizes align with standard 30-inch cooktops. You can install either unit in a typical 30-inch cabinet space without needing custom modifications.
Is the Zomagas hood easy to clean?
The Zomagas hood is designed for straightforward maintenance. It includes durable filters that are dishwasher-safe, which simplifies the cleaning process. The COSMO Delta is also easy to maintain due to its simple push-button controls and compact size. You will find the Zomagas particularly convenient if you prefer to run filters through the dishwasher rather than hand-washing them.
Can I vent the COSMO Delta outside?
Yes, the COSMO Delta supports convertible venting options. This means you can duct the air outside or recirculate it back into the kitchen. This flexibility allows you to adapt the hood to your home’s existing ductwork. The Zomagas model also offers similar venting versatility, so you can choose based on your preferred installation style rather than ventilation constraints.
Which hood is lighter?
The COSMO Delta is significantly lighter than the Zomagas model. It weighs 17.6 pounds, making it easier to handle during installation. The Zomagas unit is heavier due to its built-in insert construction and stainless steel materials. If you are installing the hood yourself, the lighter COSMO Delta will be easier to maneuver and secure to your cabinetry.
