COSMO Delta vs SNDOAS Key Specs
Installation style
The COSMO Delta is an under-cabinet range hood designed to fit beneath standard kitchen cabinets. Its slim profile makes it suitable for condos, apartments, or tight spaces where overhead clearance is limited. The SNDOAS is a wall-mount chimney-style hood. It hangs freely on the wall above the stove. This design requires different mounting considerations and may protrude more into the room. You need to choose based on your kitchen layout. If you have cabinets above your cooktop, the COSMO fits neatly underneath. If you prefer a standalone look or lack upper cabinets, the SNDOAS wall-mount style is the better option. Each suits a different cabinetry setup.
Noise level
Quiet operation is important for many kitchens. The COSMO Delta lists a noise level of 40 dB on its lowest fan speed. This measurement is taken under optimal conditions with rigid ducting. The SNDOAS specifies a noise level of less than 55 dB at its highest speed. Comparing these two numbers directly is difficult because they measure different operating states. The COSMO is very quiet on low. The SNDOAS is reasonably quiet even on high. However, the SNDOAS does not list its noise level on low speed. You cannot be sure how quiet it is when running gently. The COSMO provides a specific low-speed metric. This gives you a clearer idea of its quietest performance.
Airflow power
Airflow determines how well a hood removes smoke and odors. The SNDOAS lists a maximum airflow of 450 CFM. This is a strong rating for a 30-inch hood. It suggests the SNDOAS can move a large volume of air quickly. The COSMO Delta does not list a CFM rating in its specifications. Without this number, you cannot compare its raw suction power directly. You must assume the SNDOAS has higher maximum airflow based on the data provided. If you do heavy frying or generate a lot of steam, the SNDOAS 450 CFM rating is a clear advantage. The COSMO focuses on efficiency and quietness rather than maximum power specs.
Filter design
Both hoods use reusable aluminum mesh filters to trap grease. The SNDOAS highlights a five-layer filter design. These filters are removable and easy to clean. The COSMO Delta also includes durable reusable aluminum mesh filters. It describes them as multi-layer filters that trap grease effectively. Both models require the purchase of a carbon filter kit for ductless operation. Neither kit is included in the box. The filter maintenance is similar for both. You will need to wash the mesh filters periodically. The SNDOAS explicitly mentions the five-layer count. The COSMO mentions multi-layer construction. Both offer effective grease filtration with easy cleaning.
Dimensions and height
Height affects how the hood fits in your kitchen. The COSMO Delta is very short, standing only 5.3 inches tall. This slim height is ideal for low cabinets. The SNDOAS is a chimney hood with adjustable height. It ranges from 22.8 inches to 37.8 inches tall. This allows you to customize the look and clearance. The depth is similar, with the COSMO at 18.8 inches and the SNDOAS at 18.3 inches. The width is effectively 30 inches for both. If you need a low-profile unit, the COSMO is the only choice. If you want a tall, statement piece, the SNDOAS offers adjustable height. The height difference is significant and changes the visual impact.
Choose Your Ideal Range Hood
Apartment dweller with low clearance
The COSMO Delta fits under cabinets with a slim 5.3-inch height. Its 40 dB noise level on the lowest speed ensures quiet operation in small spaces. The under-cabinet design saves overhead space, making it ideal for condos or tight kitchens where visibility and airflow matter without cluttering the room.
Chef needing strong ventilation
The SNDOAS delivers up to 450 CFM of suction to remove smoke and odors quickly. Its 6-inch round top vent supports robust ducted airflow. The 55 dB limit at high speed handles heavy cooking loads. This wall-mount hood is built for performance, ensuring your kitchen stays clear of grease and strong smells.
User wanting bright task lighting
The SNDOAS includes LED lamps for bright visibility while cooking. The COSMO Delta lists push-button controls for lights but does not specify the lighting type or brightness in the provided data. If clear illumination is a priority for your workspace, the SNDOAS offers a defined lighting solution for night cooking.
