The COSMO COS-5MU30 range hood measures 30 inches wide, 19.75 inches deep, and 5.5 inches high. It's a compact size that's quite suitable for many kitchen spaces and still offers good ventilation.

If you're thinking about using it in a ductless setup, you'll need to get some charcoal filters separately since they're not included. The manufacturer specifically mentions a Carbon Filter Kit, part number CFK4, that's meant for this model.

Having these filters is pretty important to help with odor reduction when you're recirculating air back into your kitchen. So, if you plan on going ductless, grab that filter kit for the best experience.

Some folks have run into issues finding these filters, so to avoid any hiccups, it's a good idea to order the CFK4 Carbon Filter Kit from COSMO's website or a trusted retailer. This way, you're sure you get the right filters for your range hood.

Hey, if you're looking into the COSMO COS-5MU30 range hood and wondering about the carbon filters for ductless installation, here's the scoop.

According to our research, this model can definitely be set up for ductless use, but it doesn't come with the carbon filters you need out of the box. You'll have to get the Carbon Filter Kit, Part # CFK4, separately.

The manufacturer's description mentions that the ductless option is super handy for kitchens where you can't vent to the outside. This setup helps with circulating and managing cooking odors and fumes, but the fact that the filters aren't included can be a bit of a surprise.

Our research shows that a lot of folks have pointed this out, and it can be disappointing if you don't know beforehand.

On a positive note, having the ductless option gives you a lot of flexibility. It works well for apartments or any kitchen layout where traditional venting is a no-go. Yes, buying the filter separatel

The COSMO COS-5MU30 range hood is pretty good at managing noise across its fan speeds. According to our research, when it's on the lowest setting, it makes a soft humming sound—kind of like gentle background noise you can easily tune out.

Bump it up to medium, and it gets a bit more noticeable, but you can still hold a conversation without really shouting over it.

Now, when you crank it to the highest speed, you'll definitely hear it more, but that's expected since it's working harder to clear out smoke and odors. It's louder, sure, but it’s still within a reasonable noise range. The manufacturer mentions that it ranges from about 50 to 65 decibels, and that lines up with what a lot of people mention—especially that it's quite tame on the lower settings.

Oh, and if you're thinking of setting it up without ducts, remember that you'll need to buy the Carbon Filter Kit (Part # CFK4) separately. This filter is crucial for the ductless setup becaus
