Choose the Hauslane UC-PS18 if you need three vent paths and 6 speed settings; choose the COSMO COS-QS75 if its 7.5 in round top duct fits and you want a remote. This Cosmo vs Hauslane range hood comparison turns on airflow, duct fit and the controls you’ll use.

The UC-PS18 has a stated capacity of 860 CFM, compared with 500 CFM for the COS-QS75. Hauslane says its Power Control Technology caps airflow below 350 CFM, so consider that detail alongside the rated capacity.

Both are 30 in under cabinet hoods with stainless steel baffle filters. The slimmer COSMO COS-5MU30 is a third option if cabinet clearance is tight.

Cosmo vs Hauslane range hood: which fits your duct?

The Hauslane UC-PS18 offers more vent paths; the COSMO COS-QS75 uses a 7.5 in round top vent. Check the existing duct before you choose either hood.

The UC-PS18 supports vertical 6 in round, vertical 3-1/4 x 10 in rectangular, or horizontal 3-1/4 x 10 in rectangular venting. Its adapters for these paths are included.

The COS-QS75 requires a 7.5 in round top vent. It includes flexible ducting, while rigid ducting is sold separately.

A duct that does not line up can add work during installation. Measure its shape, width and direction, then compare those measurements with the hood’s vent options.

When does the Hauslane’s three-way venting help?

The UC-PS18 gives you more ways to connect to existing ductwork. That can help when your outlet is rectangular or exits through the wall rather than the ceiling.

The three adapter options are vertical 6 in round and vertical or horizontal 3-1/4 x 10 in rectangular. Confirm that the connection you need matches the hood’s available paths and your installation plan.

Our guide to ducted under cabinet range hoods covers what to compare when you vent outdoors. If you're deciding between venting outside and recirculating air, read what changes between convertible and ducted hoods.

When does the COSMO top vent make sense?

The COS-QS75 can suit a kitchen already set up for a 7.5 in round top duct. It vents outside, away from the home.

If your duct does not match, check whether adapting it is practical before buying. A duct adapter does not guarantee that the finished setup will meet your home's ventilation needs.

How do their airflow and fan settings compare?

The UC-PS18 has the higher stated CFM capacity, while the COS-QS75 offers 4 speeds and the UC-PS18 offers 6. More settings can give you finer control over fan speed, but duct fit and cooking needs still matter.

The COS-QS75 is rated at 500 CFM and has a 4-speed fan. COSMO gives a lowest-speed noise level of 40 dB under optimal conditions with rigid ducting, which is sold separately.

The UC-PS18 is rated at 860 CFM. Hauslane describes its dual motor and duct system as designed to reduce airflow noise, but the product details here give no comparable decibel figure.

Hauslane also says Power Control Technology caps airflow below 350 CFM. That is an important limitation to consider if you are comparing the hood’s stated CFM with your ventilation plan.

For a closer look at airflow needs, see how many CFM a range hood needs. Our sones vs decibels guide explains how to interpret noise measurements.

Which controls and lights suit your routine?

Choose the COS-QS75 for touch controls plus a wireless remote; choose the UC-PS18 for a 6-speed touch screen and delay shutoff. Think about where you stand while cooking and which controls you will reach most often.

The COS-QS75 touch panel operates power, lights and fan speed. Its wireless remote can help when you want to change settings without reaching the hood.

The UC-PS18 has a touch screen, 6 fan speeds and delay shutoff. Its swappable GU10 LED bulbs let you match the light color to your kitchen.

Both hoods use LED lighting. Check the control layout and bulb details against your preferences before ordering, especially if you want a specific light color.

Which hood is easier to fit under a cabinet?

The COS-QS75 is 10 in high; the UC-PS18 is 8-1/8 in high. Their widths and depths are close, so height and duct alignment may decide which fits your space.

The COS-QS75 measures 29.5 in wide, 22 in deep and 10 in high. The UC-PS18 measures 29-3/4 in wide, 22 in deep and 8-1/8 in high.

Measure the available cabinet opening and the path from the duct to the hood. Check the installation instructions for clearances and mounting requirements before you commit.

For help measuring your space, use our under cabinet range hood size guide. If you’re replacing an existing hood, our guide to replacing an under cabinet range hood covers the planning steps.

How do the filters and upkeep compare?

Both models have dishwasher-safe stainless steel baffle filters. The COS-5MU30 differs with reusable aluminum mesh filters.

The COS-QS75 has permanent ARC-FLOW stainless steel filters that COSMO describes as dishwasher-safe. The UC-PS18 includes dishwasher-safe stainless steel baffle filters.

The COS-5MU30 uses reusable aluminum mesh filters and is 5.5 in high. Its shorter profile may help where cabinet clearance matters, though its 3-speed motor and 5 in round duct are different from the two main contenders.

Choose a filter type you can clean on a regular schedule. Our baffle vs mesh filter guide explains the practical differences.

Can either model work without an outside duct?

The COS-QS75 can convert to ductless use with a separately sold carbon filter kit; the supplied UC-PS18 details describe ducted venting. Check the exact setup before choosing if you cannot vent outdoors.

The COS-QS75 needs the CFK5 carbon filter kit for ductless conversion, sold separately. The COS-5MU30 can also convert with its optional CFK4 carbon filter kit.

The UC-PS18 details list three ducted paths. They do not describe a recirculating conversion, so confirm with Hauslane if your kitchen needs a ductless configuration.

Ductless hoods recirculate air through filters instead of sending it outdoors. Read how recirculating range hoods work to understand what that setup involves.

Which range hood should you buy?

Pick the Hauslane UC-PS18 if its three vent paths fit your kitchen and you want 6 speed settings; pick the COSMO COS-QS75 if its 7.5 in round top duct fits and you want the included remote. The COS-5MU30 is worth considering when a 5.5 in hood height is the key constraint.

Our score weighs specs, features and buyer feedback against what you’re shopping for. The Hauslane scores 9.1, the COS-5MU30 scores 8.9, and the COS-QS75 scores 8.7.

Before you buy, match the vent to the duct, compare the hood’s dimensions with your cabinet, and check whether you need a separate filter kit. For broader options, see our best 30 inch under cabinet range hoods and COSMO COS-5MU30 review.

Frequently asked questions

Is Cosmo or Hauslane better for an under cabinet range hood?

Hauslane suits you if its three vent paths fit your ductwork and you want 6 speed settings. The COSMO COS-QS75 suits you if a 7.5 in round top vent fits and you value its wireless remote.

Measure the opening and check the hood dimensions before choosing.

Which has more airflow, the COSMO COS-QS75 or Hauslane UC-PS18?

The Hauslane UC-PS18 has a stated airflow capacity of 860 CFM, while the COSMO COS-QS75 is rated at 500 CFM. Hauslane also says Power Control Technology caps airflow below 350 CFM, so review the model’s setup details and your ventilation needs before deciding.

Can the COSMO COS-QS75 be used without outside ducting?

Yes, COSMO says the COS-QS75 can convert to ductless operation with a separately sold CFK5 carbon filter kit. The UC-PS18 details here describe three ducted vent paths; check with Hauslane about a recirculating setup if you need one.

What is the main difference between the COS-QS75 and COS-5MU30?

The COS-QS75 is 10 in high, has a touch panel, 4 speeds and a wireless remote; the COS-5MU30 is 5.5 in high, has push buttons and 3 speeds. Their duct requirements also differ: 7.5 in round for the QS75 and 5 in round for the 5MU30.

What should I measure before buying either range hood?

Measure the cabinet opening, hood width and depth, and the duct size and direction. The COS-QS75 measures 29.5 x 22 x 10 in and has a 7.5 in round top vent.

The UC-PS18 measures 29-3/4 x 22 x 8-1/8 in and supports three vent paths.
