Replacement cooker hood filter reducing airflow

[Bertie78]

I bought a WPRO Type 145 cooker hood filter from espares. The new filter has a thin paper material over one side of the filter, and the airflow is drastically reduced from what it was with the original filter that came with the unit. Is this a bad thing? It feels to me on the exhaust vents at the top that only a small amount of air is coming out. I have posted a photo of the old and new filters side by side. The old one doesn't have the paper material at all.

It is listed as the correct part for the Indesit H361 cooker hood but I'm baffled why they would design a part that reduces airflow so much. It makes me wonder if Whirlpool have made a generic part for different models that doesn't take into account the power of the fan unit in the Indesit H361.

That looks like a grease filter over the carbon filling so I would imagine that it would restrict the flow. But these type of recirculating hoods are next to useless, can you exhaust to outside. Also can I see the aluminium slot in section underneath -- I periodically put mine in the dishwasher keeps the grease down although they do look clean

I looked at the H361 cooker hood, and it does seem it can be either a simple filter or it can expel cooking fumes outside, as to if this alters the filters used I don't know, but the ones shown with internet hunt

do not seem to have that paper on them.

I use electric cooking, so don't need a flue, with gas clearly you do, but I have never even looked to see if there is a filter in the hood, I see the vent lift outside so I know it works, but I have never even looked to see air flow.

Thanks. If I had known the grease filter reduced the airflow I would have gone with the ones in the photo above as I cannot filter outside in the flat I am in. Yes, I cleaned the aluminium section recently. I might get third party ones the next time.

Wondering - can you rip off the paper filter or will all the carbon grit fall out if you do

Surely if you only have the fan recirculating - not ducted to outside - then you want the grease filter.

That it reduces the flow is obvious but unimportant.

Seems like it will fall out.

Well, this is what I needed to know. In my ignorance I thought it might not be good for what seems like a powerful fan unit. I'll see how it performs when cooking and go for the other type if I need to.

There is that but the grease filter is the aluminium slot in and out sections I mentioned earlier seen in the OP photo

Fair enough but Bertie did say:

Fair enough but Bertie did say:

I think that is the problem with these spare part places, they are listed as fitting but not always the same design.

@Bertie78 Just a thought - can you take apart both of them and swap the internal carbon beads.
Actually should be a thing to be able to buy spare bags of carbon.

Why would you need to filter the expelled air, to the outdoors?

Yes, I was about to say that. II bought a heating element for an oven from one spares company which had listed it as the correct part when it wasn't. They only removed the model number from their compatible list when ebay refunded me. They had the nerve to tell me to modify it to make it fit. You can't always trust these sites.

The less the recirculated air is filtered, the more pointless the unit becomes.

When use as discharged to outside you leave the filters off.
