Hi

I'm currently living in a big kitchen/living room area (88m2: 8m x 11m). When we cook deep fry foods (in normal pan), the smoke is lingering overnight.

I currently have a rangehood with max airflow spec of 760m3/hr.

Do you think I should:
- replace it with a bigger airflow capacity (I heard German rangehood brand schweigen has a big outside motor that can make it a silent operating)
- buy an air purifier instead, as I heard it can circulate and filter the food smoke
- buy a deep fryer to 'retains' the food smoke within it

Update: current rangehood: Technika TB10900SS-2

Thanks

    Rangehood and window.

      You can't just have a window. You need to know how-to open it too.

    • BigLeviathan on 29/04/2020 - 16:13

      Thanks, currently I have 3 x small awning window type.

      I guess not circulating air as much

    We have a Whispair (Same concept as a Schweigen) and can vouch for the quiet operation.
    I'd guess Speed 3 is around the same audible level as speed 1 on my old unit. Speeds 1 and 2 you can barely hear.

    It gets fairly noisy on high speeds, due to the rush of air, but it pulls way more air than my previous Rangehood and is also far quieter… We rarely use speed three and never use speed 4.
    My Vegetarian Sister-in-Law is sold on getting one cause we cooked bacon (for us) and she couldn't smell it cooking!

    I doubt an air-purifier would cope.. It would certainly take a considerable time.
    And I'm not sure that a deep fryer is going to solve a smoke problem.

      Thanks for your feedback and thanks to let me know how quiet and effective it is when you are cooking.

      Would you be able to let me know:
      - Your kitchen size
      - Whispair model (including the max airflow if possible) as a comparison

        60cm Whispair Zurich with 1140m3 motor unit
        The motor unit is selectable separately from the internal unit, I chose to upsize it (can't recall what the default package size was), which in hindsight was unnecessary. There's not enough outlet area in a 60cm to require the extra airflow.

        Our kitchen is reasonably large, a bit over 5x3m with 2.6m ceilings (or higher, we knocked out a wall and one ceiling is lower than the other but there's an LVL separating the 2 ceilings so not really noticeable) so around 39 cubic metres

        • BigLeviathan on 03/05/2020 - 21:53

          Thanks for this

          I have a 2.4m height kitchen, thus it'll be 211.2 cubic (8W x 11L x 2.4H)

          By comparing that, I have a strong feeling that I would need a higher rangehood speed than the current one

          • ESEMCE on 04/05/2020 - 10:17

            @BigLeviathan: The intention is not to suck all the air out of the room… It's to suck up the fat and odours from your cooking.
            As such, it shouldn't really matter the volume of your kitchen, I only added that info cause you asked.

            The only thing that matters really is how wide is your preparation area and is the airflow through that area sufficient to pull all the cooking odours and fats up the flue?
            Unless you're in a commercial kitchen with cooking going on around all 4 walls, I suspect that something in the 1000m3 range will be more than sufficient.

    Or use an oil that doesn't smoke as much. Rice bran oil.

    if you cook asian food, i would recommend the rangehood brand Robam

    • BigLeviathan on 29/04/2020 - 16:16

      Thanks, I'll check it out; hopefully, it runs quiet :)

    • BigLeviathan on 29/04/2020 - 21:27

      Wow! The advertisement looks so convincing, I might check it out if the installation not too expensive

      Are you using it yourself? how big is your kitchen size? is it very loud?

        U shaped kitchen, not big but not small (enough for 2 people to cook together in it). On level 6 (which is full power), it can be quite noisy but on level 3, it’s fine

        When we were redoing our kitchen, we looked at Schwiegen but couldn’t justify the price. Friend of ours recommended Robam, went to their location in Oakleigh (not sure where you’re located but in Melbourne) and they did the 8kg block test and it was legit.

        • BigLeviathan on 30/04/2020 - 19:55

          Have you been dealing with their support/after sales care? Saw this review post and got bit worried

            @BigLeviathan: never dealt with them, but ours was purchased in 2017 (CXW200A822 90cm Canopy Rangehood with 1800m³/hr air flow.) and haven't had any issues. There's definitely a difference between level 3 and level 6 though in terms of suction

  • Caped Baldy on 29/04/2020 - 09:52

    Buy an air fryer.

    The question is, does your rangehood simply recirculate, vent into the wall cavity, ceiling cavity or outside at the moment? Everybody automatically will guess 'Outside', but I think a lot of people will be shocked to find out.

    • BigLeviathan on 29/04/2020 - 16:11

      Mine goes out (I can see the exhaust pipe on top of my roof).
      For your reference, the rangehood that I have is Technika TB10900SS-2

    Have you checked you've got a filter in your rangehood? It helps to filter out the grease etc in the air rather than just redistributing it to elsewhere in your kitchen.

    If so, does that need replacing & does your rangehood need cleaning?

    • BigLeviathan on 29/04/2020 - 18:58

      I've cleaned the filter by soaking it in soap and a little bit of vinegar, I also done the cleaning (outside and around the filter), I didnt touch the inside bit just afraid of the electrical shock

      • Love a bargain on 29/04/2020 - 21:11

        Sorry for using the wrong terminology. When I said filter, I was actually thinking about a filter pad (something like this but you can probably find some specifically cut to the size of your specific model) rather than the metal filter.

        The pad helps to filter air and absorb odours, and you simply replace it when it gets too yucky

        • BigLeviathan on 29/04/2020 - 21:26

          Thanks for the suggestion! I just checked mine and was able to change the metal filter mesh myself (I felt like superman now, as I'm not so much a handyman but felt that I can do DIY stuff now haha), it was just a small screw that holds the metal mesh and just wiggle it to pop it open

          But one thing though, the fact it sucks the air out of the kitchen to the outside (mine has a small chimney on the roof where the rangehood is located), why do I need to extra filter it to make it 'cleaner'?

            @BigLeviathan: well… because I didn't know what type you had when I first responded and assumed you'd a recirculating type as they're very common these days (esp in units) and a common reason for lingering cooking odours

  • Capo93 on 30/04/2020 - 20:04

    That unit is not a recirculation unit, recirculation units normally come with extra charcoal filter so first thing I would do is remove the flu cover off the existing range hood and ensure that the flu goes into the ceiling space or outside.

    I have seen plenty of dodgy range hood installation where you take the flu covers off and the flu cover and gyprock is just covered in oil and crap because its not venting outside, its basically just recirculating.

    • BigLeviathan on 01/05/2020 - 13:43

      When I run the rangehood in the house, I can hear the slight noise outside (near the chimney thingy), plus when I cleaned the metal mesh filter, I can see a couple of dead flies, I would imagine it does, even though it might not come with the drafter (I hope I'm using the right terms here) to stop the inbound cold air during winter (thus the flies trapped on the motor side)

      • Capo93 on 03/05/2020 - 00:20

        Sometimes the motors have no return flaps on them that open with the force of the air being pushed out. Sometimes the flap can get caught and not open or only one flap opening which can obviously result in reduced suction.

        Get a A4 piece of paper, put the range hood on low speed and see if it holds the paper up against the filter.

        • BigLeviathan on 03/05/2020 - 21:49

          Thanks for the suggestion, really appreciate it!

          I tested this with A4 paper and it does stuck on a low fan.

          I wonder whether now I should get a kitchen appliance store to get someone assess the current rangehood, whether it works as expected or getting a different brand

            @BigLeviathan: Some other points to check:

            Check to make sure it’s actually ducted outside, as I mentioned previously I’ve seen range hood not ducted outside, just blowing into the flu cover so it’s basically only recirculating(I’m a Applaince repair tech)

            Check to see if it’s ducted to just in the roof cavity or outside. Is outside vent blocked or something.

            Next time you cook something oily or Smokey run the range hood with no filters in it and see if it clears the smoke out better, if it does I would be looking at giving the filters a good degrease or replacing them as they are dirty.
