Frequently Asked Questions
1. What is baffle filter?
Range Hoods’ Charcoal filters use a series of inverted cup shaped "baffles", which cool the moist greasy air as it flows though, condensing/catching oil and then allowing the grease and moisture to flow down into the lower trough (where it is held until cleaning). Recent popularity of the commercial look in residential kitchens has created a very high demand for baffle filters. The extra expanse of stainless steel underneath the ranger hoods does make for a more professional, industrial appearance. Performance wise, baffle filters allow much better air flow at the expense of trapping a bit less grease.
 
2. What Size and CFM is recommended for residential kitchen range hoods?
The majority of people purchase the same width range hoods as the range, but interior designers are increasingly pairing larger range hoods with smaller ovens. The extra expanse of stainless steel of range hoods lend a more "serious" commercial flare to any design. Smoke and steam plume as they come off the cooktop, so installing a wider range hoods make perfect functional sense, allowing lower fan speeds to be more effective. A good rule of thumb for any gas or electric range is 50CFM per square foot of cooktop. Thus, a 36 inch wide range would require at least a 300CFM range hoods and all non-recirculating.
 
3. How far can I run my ductwork?
You want the ductwork as short as possible and with as few 90 degree bends as possible. The longer the ductwork and the more the duct changes direction the more air pressure that builds up in the ductwork and the effective CFM is reduced.
 
4. Can I duct the Range Hood into my attic or crawl space?
No. You should never exhaust air into spaces within walls, ceilings, attics, crawl space or garages. The humidity and grease collect in this space.
 
5. What is the difference between a ducted range hood and ductless range hood?
Often called a re-circulating range hood a ductless hood will filter the air, generally through carbon filters, and return the air back into the kitchen area. Ducted Range Hoods do not use or need charcoal filters because they remove the air to the outside of the house through “ductwork” this ductwork is normally 6″-10″, depending on the size and requirement of air to be removed. Obviously the fully ducted type of range hood is preferred but this is not always possible.
 
6. What type of electrical connection do I need?
Range Hoods should not be direct wired. All XtremeAIR brand range hoods are wired with a standard grounded plug. The electrical connection a standard 110v/60hz grounded outlet is used.
 
7. What caution should I take when cleaning interior of range hoods?
Interior cleaning, Warning! Be sure the range hoods are turned off before you clean them. Also avoid spraying cleaner directly onto the light bulb or light bulb socket. Keeping the interior of range hoods clean can help the motor to run smoother
