1. The filter is connected properly, but it still smells.

Verification procedure:

  • Turn the extractor hood on in setting 1.
  • Can you see the filter? Look if the red light is burning. Can’t see the filter? Then look if you can notice some red glow of the light. If you can’t notice any red light at all, look if you can easily remove the shaft, and if you can observe some red light afterwards.
  • Is the blue light turned on? If not, put the extractor/cooker hood in a higher setting (e.g. 3 or 4). Is the light burning now, proceed to step 4.

3. I smell a fresh scent, which is too dominant.

We call this scent ionization / “fresh mountain air”.

  • The filter works.
  • We advise you to turn the extractor hood off, 15 to 20 minutes after cooking. This is also mentioned in the manual.

Tip: The time which the extractor hood is required to run also depends on the time used to cook and the size of the room.

Tip 2: You can always turn the extractor hood on for about fifteen minutes if it e.g. smells inside the house or if someone in the house is smoking, etc.

Tip 3: If you believe the air is clean enough, you can turn the extractor hood off at any time.

Note: ventilation is mandatory during recirculation.

4. The filter only works at a high setting.

  • You probably have an extractor/cooker hood with a low airflow.
  • Our advice is to tape the outer two rings of the filter. This way, the sensitivity of the sensor on the filter increases. The air passage will be approximately 100mm, which causes the filter to react in the case of a low airflow. The outer two rings can be located at the bottom of the filter.
  • Are the rings taped and is the filter still not working properly? Then it’s possible to exchange the filter for a new one.

5. Everything in house gets fogged up

You have a ventilation problem. The moisture goes through the filter, but it’s also blown back into the room.

Do you have windows in single glass? These condense very quickly. Our advice is to ventilate the room better, by e.g. opening a window. This also improves the entire indoor air climate.

New homes are usually equipped with a good ventilation system (CMRV).

6. I smell a fragrance resembling metal/ozone.

This isn’t ozone air. The filter produces plasma, but no ozone. What you are smelling is called ionisation, also see question 3. Our filter has been certified by the TÜV and meets the most stringent testing standards.

Note: ventilation is mandatory during recirculation.

7. Is recirculation mandatory (in new homes)?

Actually, this is not mandatory. However, since 2015 it is required to lower the EPC (Energy Performance Coefficient) of new homes from 0.6 to 0.4 in the EPC calculation. This is done when the extractor hood recirculates, increasing the energy efficiency of the residence.

The EU has determined that new homes may not discharge or drain any energy outdoors starting from 2021 (EPC 0).

When one recirculates, the heat also remains in the home. This means that less energy is required to heat the residence > thus improving the energy efficiency of the home. This will ultimately also be adapted into the NEN 7120 (Building Act).

8. The filter housing is broken.

If the filter housing is broken (all parts which are composed of plastic), you can return the filter and a new one will be sent shortly.

Caution: in this case, there can be no more than three months between the invoice and the report.

For other information concerning the exchange of a product, see the exchange warranty.

12. Where does the moisture go?

The moisture goes through the filter and remains inside the house, which is why it has to be ventilated sufficiently. (also see point 5).

Our filter has received an Appliance 3 certificate. This means that the filter withstand moisture. It will not break due to moisture and is fit to be placed inside humid rooms (e.g. a bathroom).

13. What is the yield of the filter?

  • At setting 1 – 200 cubic metres the yield is 100%
  • At setting 2 – 400 cubic metres the yield is 83%
  • At setting 3 – 600 cubic metres the yield is 67%
  • At setting 4 – 800 cubic metres the yield is 50%
  • 1000 cubic metres is also possible! But 800 is the most common for extractor hoods. 1000 cubic metres also has a yield of 50%.

It’s not necessary to configure the extractor hood in a higher setting. The time period remains the same; it only makes more noise.

Caution: the yield is calculated on scent. In the case of baking fumes, it is required to run the extractor hood a bit longer. This is different.

14. What does the filter do with fats?

Fat may go through the fat pre-filter of the extractor hood and is eliminated inside the filter. The fat is stored in a fiberglass pad which is located between the two electric cores.

If the fat accumulates between the electric cores, a little current will occur which destroys the fat (think of it as a kind of fly trap/lamp)

Small particles of fat are destroyed with plasma and the dust is blown out of the filter by the air pressure of the motor.

Caution: always use a fat pre-filter. Not only for the filter, but also to maintain (lifespan) the motor of the extractor/cooker hood itself.

17. I notice the smell of the food, not in the kitchen, but in another, different space.

This can be logically explained. The filter only cleans the room in which is it placed. If other scents/fragrances and smells escape to another room, they cannot be filtered. That’s why it’s important to cook in an enclosed space. Do you have an open kitchen? Then it’s important to turn on the filter well in advance so the airflow is already circulating before you start cooking. This way, you prevent odors from escaping.

18. What is the minimum size of the grid that is placed in the extractor for recirculation?

The passage must be at least around 150mm in area (pi x r2). It is best to enlarge the passage. For example, 2 times the area of the outlet nozzle of the engine. If the bore is too small, the engine won’t be able to release its air pressure and the filter will clog due to a lack of airflow. The consequence of this is that the filter becomes defective over time. We do not provide warranty for this issue.

19. Grease coming out of the extractor hood

The underside of the hood is greasy:

This has nothing to do with the PlasmaMade filter.
Hint: clean the underside of the hood.

There’s fat dripping out of the metal grease filters:

This has nothing to do with the PlasmaMade filter.
It may be that the default grease filters are quite thin, which is why the fat isn’t absorbed sufficiently.

If the grease isn’t hold back by the filters, it could damage the engine of the hood.
In the engine there’s a wheel, and if that wheel is full of fat, it will start to slip when it turns, allowing the grease to drip inside the seam of the engine housing.

Hint: frequently clean the grease filters in soapy water or in the dishwasher at a temperature of at least 70 degrees. Does the problem continue to occur? Then please contact the manufacturer of your extractor hood.

The PlasmaMade Airfilter is positioned on the outlet nozzle on the engine where there’s also an extra pipe/channel if you have an outdoors outlet. Our filter may remove the last grease particles; however, this is not possible when those are already held back before the engine.

20. No air coming out of the extractor hood

  1. First, check if there are slots in the shaft so that the air can be recirculated in the room.
  2. Check if the extractor hood is properly connected. Verify if all functions work and if the engine is running.
  3. Make sure that the check valve of the engine is removed. Some extractor hoods still have these, and if those are not removed, the air can’t go through because the tabs are pushed against the filter and therefore not open. Is it still there? Remove it.

Is the problem still not solved? Please contact the vendor of your extractor hood.

21. The ceiling or wall is dirty due to the air from the grid of the hood

This issue can have many causes. First, we recommend you to check if the PlasmaMade filter is correctly mounted and functions properly.  If you determined that with certainty, then check if the grid meets the following conditions:

  1. Is it 50 cm away from the ceiling or wall? And does it not blow the air directly against the wall, but into the room (see mounting manual)?
  2. Is the grid large enough to slowly blow the air from the shaft or extractor hood back into the room (see question 18)?
  3. Is the capacity of the engine in the extractor hood not too large so it does not blow the air too fast through the filter, not allowing it to be cleaned. Our advice: extraction at level 1 or 2 with approximately 200/300m3, which produces the best results.

We advise you to also install the carbon filters per question 22. The carbon filters do not need to be replaced and can just stay put. Of course, you can clean the wall or ceiling with some soapy water.

22. Is it necessary to use the standard carbon filters that are included with the extractor hood?

No, this is not necessary, our filter can be used without any of these supplied carbon filters.
However, it does not hurt to place these filters. In some cases, the air is distributed better, which benefits the overall operation.

You do not need to replace these filters every two months when they are used in conjunction with our PlasmaMade Airfilter. You can continue to use these filters for a long duration, just like our filter.

However, it is wise to occasionally (every 6 months) clean the carbon mat on the filter with some hot water.

You can reach this carbon mat by removing the metal grease filter from the hood. You will then most likely see the carbon filter and easily remove it. If this does not work, please contact the supplier of the extractor hood.

23. I do not have a stainless-steel shaft but a wooden valance. Should I protect it from moisture?

Please be aware that the air should be easily recirculated into the room whenever you mount a PlasmaMade Airfilter. Therefore, it is important that you ensure that the air vent (grid) is large enough (at least the size of the outlet nozzle of the engine). Our advice: twice as large or even larger if possible.

If you do not have a stainless-steel shaft, it is advisable to provide the interior of a good paint job or varnish it so that the moisture cannot affect the wood. Or make sure that the PlasmaMade Airfilter is placed in a metal or plastic box and that the air is subsequently blown back into the room.

25. The blue light blinks during operation.

This means that the maximum cleaning time of the filter has been reached. The filter can last up to 60 minutes. If you want to re-enable the filter, turn of the extractor hood, wait for 2 minutes and then re-enable the extractor hood.

Exchange warranty
