One of the absolute worst things about cooker hoods, in my view, is the
noise they make. Have been looking around and seen, for example, some
Bosch ones are claimed to be super-quiet.

What I have been wondering is whether this is classic marketing - sure
you can cut the noise, you turn the fan down so low it is useless. And
at the other end, I suspect all of them are noisy at full speed.

I also like the idea that some don't end up with sharp corner, foreheads
for the gouging of. And if they are going to have lights, LEDs with
decent colour rendering.

Suggestions of how to choose a decent, quiet cooker hood - without
completely busting the bank - including specific makes and models.

Whatever you get, do the usual thing & mount motor, fan assy and whole hood on rubber tap washers. Add damping material onto the sheet metal.

One thing to note - if you do a lot of frying then oil/fat will go through
the filter and into the extractor fan and ducting. At least, that is what
happens with out metal mesh "washable" filter.

If the fan and ducting (or at least the ducting) are, for example, over a
kitchen unit away from the hood then the fats tend to stay in the ducting.
[This does, of course, potentially store up problems in the long term.]

If not, they tend to accumulate directly above the extractor, and after a
while start to drip back down onto the filter, run through the filter,
then drip back onto the hob (or whatever is currently on it).

Temporary measure is to add some kind of disposable filter above the mesh
(such as a J cloth). Keep forgetting to change it, though :-(

So orientation of the fan and ducting can be important, and the filter
type as well.

In my limited experience metal mesh filters which you can stick in the
dish washer do have a long life but are not really that effective at
cleaning the extracted air.

The tap washer trick is pretty easy. It's normally well worth trying to
decouple shower pumps, and make sure that pipes are not touching battens
or panels.

It's easy to do and has made a big difference to noise levels IME. I've done it many times on various motors & fans. Jim is a bit short of content as ever.

Not big on frying - though I do some so it is important.

It will be directly above the hob and vented straight out through the wall.

Very largely it is because the house is so well sealed compared with our
present location, I expect general cooking smells, oil, steam, etc. to
hang about a bit more.

If the house is really well sealed you may need to install a vent to provide make-up air to replace that being extracted.

It seems to be pretty good but not totally air-tight. And there will be,
for example, an extractor fan in the utility, off the kitchen, through
which air can come - as well as the possibility (shock!) or opening a

Unless that fan is also running, in which case your house will implode :-)

If it's direct through the wall just use a 12" wall fan. A bit noisy while running but will clear the air in a typical kitchen in about 2 minutes.

What we really want is something very quiet that keeps the levels of
steam, smell, oil/grease, and so on nice and low over longer periods.

Two minutes of jet engine ain't going to cut the mustard - even if it

Sorry for late post, I don't get much time at the moment.

I have a Bosch Exxcel DWB09E752B Chimney Hood.
It is pretty quiet, certainly on the lowest setting, which is powerful enough for 3 pans boiling away merrily.

Mine currently makes an interesting noise before the 2 gravity back-draught flaps pop open - I think there's a bit of grease in there. ! So it seems to be able to generate a bit of pressure.
I've also mounted it quite high so I don't bang my head on it.

I've seen some horrendous hoods rattling away about 2 feet above the stove where you can't even see into the rear pans. Eventual project is to replace the halogens spotlights with LEDS.

Now where are those nappies ...

The thread was started by me asking about choosing a cooker hood - by
implication, but not expressly stated, a new one.

I actually wanted to find a suitable hood that doesn't need this sort of
fettling. I know this is a D-I-Y forum, but in this case, it will be
fitted by a kitchen fitter. It isn't easy to explain to someone 200
miles away that he should do all sorts of unusual things to something
that I will never have seen. It needs to be quiet when fitted according
to the manufacturer's instructions.

That's what I thought when reading the bunkum about taking new
cooker hoods apart and re-engineering them with tap washers
between various components, never mind the fact that most hood
fans and motors are combined (IME - dunno bout Nige's...) ;-)


I suppose the ultimate would be a remote fan setup but I suspect
budget and space would preclude that?

So I would be looking at larger hoods with greater filter surface
area and larger motors, and thinking to use their lower fan
speeds (so reduced noise) to do the necessary venting. I expect
the fitter will have some ideas if what and what not to do (and
how many tap washers he would need :-D)

I once looked at the noise issue, just by going through specs and
brochures. It was a few years ago. My conclusion was that noise was
proportional to wattage, regardless of cost or quality. You could
however with some models mount the motor elsewhere, like on the outside
wall, and then you got a lot less noise.

the filter and into the extractor fan and ducting. At least, that is what

How often do you (dish)wash it though?
The metal filters are just grease filters. They won't catch it all
so a film on the inside of ducts & fans would be
expected.

If the fan and ducting (or at least the ducting) are, for example, over a
kitchen unit away from the hood then the fats tend to stay in the ducting.
[This does, of course, potentially store up problems in the long term.]

If not, they tend to accumulate directly above the extractor, and after a
while start to drip back down onto the filter, run through the filter,
then drip back onto the hob (or whatever is currently on it).

Bleurgh! Too late with the cleaning shurely?

Temporary measure is to add some kind of disposable filter above the mesh
(such as a J cloth). Keep forgetting to change it, though :-(

An airpath with some 90 degree turns can greatly reduce noise. The more such turns the better. The baffles used to contruct need to be stiff or damping enough to not transmit the noise straight through them.

Or you need a foam filter like you get in some vacuums, and a higher
pressure fan to keep the air moving, but his does then make it essential
that the is easy to remove and clean.
