Pros and cons of Internal, External Blowers and Ductless Hoods.

 It is critical to do some research on different types of ventilation systems when buying a new cooking range online. There are three main types of ventilation systems: internal blower, inline/remote blower, and ductless hoods. By weighing the pros and cons of each type of hood, you can make the smartest choice for your project. 

• Ductless Conversion

Recirculating hoods use a fan with filters to recycle air back into the kitchen after removing grease and cooking odors.

Pros 

It is super easy to install and remove the ductless range hoods as you don’t need to have it  connected to any duct.

Generally, they are more affordable than duct-ed range hood. 

Cons

It only filter grease and cooking odors from the air and re-circulates clean air into the room. This means that your kitchen might get humid.

It requires regular maintenance and the hood filter should be removed and cleaned in the dishwasher.

• Internal Motor

Range Hoods have blowers mounted inside the hood. The range hood cover, the blower motor, baffle filters, fan controls and lighting all come in one unit.

Pros

It is easier to install and access the internal motor. Well functioning and lower budget than remote blower and are most selected for most kitchens

Cons

Large CFM internal blowers tend to be noisier than the other types.

• Remote Blower

Motor is located outside of the range hood. You can either mount the blower outside of the house,on an outside wall /on the roof, or you can place it inside the house, in the attic.

Pros

They usually has high-efficiency output,ranging from 800 to 1200 CFM rating.

You can also benefit from its quiet operation since the blower is located outside of the hood,and not inside the kitchen.

Cons

Installing a remote blower is a new trending and it might takes more time and effort for labor to install the blower. Also it is higher budget.
