Range Hoods

Now I'm picking out an exhaust hood to go over the stove. The higher the CFM/lower the noise the better. It seems at this level, there are a few candidates -- namely from Sakura and Zephyr. Can anyone tell me about their experience with these products?

    Is your stove gas or electric? With electric you can get by with lower CFM ratings. Not so with gas or high BTU output gas. You should consult a professional with a gas appliance in mind.


    1. I can't comment on those brands, but there are some range hoods (mine is a Thermador, but there are others) that have a separate blower that's mounted outside of the house, at the other end of the exhause duct. Much quieter, and because it doesn't have to fit inside the hood it can provide more CFM.

      1. I'm very happy with my Zephyr. The hood vents out the roof of the house. I had an issue for a while in that only the replacement light bulbs available only directly from Zephyr would fit...they are a fraction of an inch longer than the everyday bulbs of the same model. But, they must have realized this as they sent me instructions with the last bulbs I ordered on how to adjust the sockets to accept the more easily available bulbs.

        1. I am an exhaust fan nut. I love to use very high heat for grilling and woking and it really throws off some cooking effluvia. As you may have observed there is an inverse relationship with CFM and noise. Flyfish is correct, an outdoor mounted fan solves the problem nicely. I have a Thermador that will suck the cat right off the floor! I also opted for the accessory SS back wall with dropdown shelves and warming lights. Very handy! And go for the more expensive but sturdier and easier to clean louvered filters.

          1. It's a gas stove. I'm wondering if I can get away with a 4" duct, or at least a 6" that steps down to 4" (the size of the hole in the wall.)

              Within reason, and with the room to fit adapters, you can run with just about any size duct, but if it's not properly sized for the capacity of the fan (not just diameter, but maximum length and number of bends as well) there will be a penalty in decreased CFM. The specs for the hood (or blower) should state the recommended duct size. My Thermador 48" hood pulls up to 1000 CFM and uses a 10" duct, which has a cross-sectional area over 6 times larger than a 4"duct. I don't have any numbers in front of me, but my sense is that 4" is much too small for any hood that's worth having.

                My thoughts exactly. I am almost certain that building codes will not allow anything smaller than a rectangle of 3x10 or a 6" round. Bigger ducts will take up more room and potentially cost more, but even for "regular" home appliances will perform better.
