Top 3 Best Remote Blower Range Hoods

Why Install A Inline Blower Range Hood?
Inline blowers, also known as remote blowers, are a great way to get a nearly silent range hood. Inline blower fans are installed in either an attic, basement, or sealed crawlspace.
The existing range hood stays in place, but the blower is removed, so when you turn on the hood only the inline blower turns on. This is pretty much the only way you can remove most of the noise from a range hood. It won't be 100% silent just because moving air flow still creates a sound, but it will be significantly quieter.
And the loud noise from range hoods is probably the number one complaint among homeowners.

How Do The Control Work For Inline Blowers?
Most inline blowers can simply be wired to the existing hood, and you don't need to change the control buttons.
However, other range hoods have separate controls that you will have to mount to the existing range hood.
What Is The Sizing (CFM) Of Inline Blower Range Hoods?
Inline blower fans range from around 200-cfm and all the way up to 1000+ cfm. CFM stands for cubic feet per minute and is a measurement of exhaust capacity or speed.
Inline external blowers tend to have more than the average range hood CFM just because they make less noise.

However, homeowners should be aware that if a range hood exhausts over 400 cfm, they may need to buy an additional automatic makeup air system. A makeup air system will bring in fresh air to the home in order to prevent a negative air pressurization problem in the home.
If there are gas appliances in the home, an overly powerful CFM hood can cause hazardous back drafting which can lead to carbon monoxide poisoning. Back drafting is a phenomenon when the exhaust gases from a gas appliance don't properly exit to the outside, but are pulled back into the interior of the home.
