Hello
I have a newly built, 5-year-old passive house equipped with a ventilation system.
Lately, I have been thinking a lot about cleaning the ducts installed inside the building structure, since these are not accessible for removing construction dust and accumulated dirt.
I have now taken some photos with an inspection camera, showing about a 1 cm (0.4 inch) layer of dust inside the exhaust duct, which is not ideal.
After much consideration, I have found a partner with whom I have solved this problem.
We offer efficient cleaning using a cleaning pig. However, before we enter the market (planned for 1.1.2019), I wanted to hear some feedback regarding new buildings with ventilation systems.
This concerns systems installed with distributors and plastic ducts.
We would like to limit our service initially to the NRW area, but here I am interested in a realistic assessment from owners of such systems.
I have one myself and want to continue breathing clean air, not dirty, dusty air...
The method we offer is truly effective and efficient.
So, let’s hear your thoughts.

As mentioned, dust in the supply and exhaust air ducts must be removed.
VDI 6022 recommends cleaning the ducts every 3 years. It is in your own interest to clean both exhaust and supply air ducts.Use an F7 filter in the supply air.
Mottenhausen is right. If the product is really that great and new, the better idea would be to sell the cleaning method and equipment to specialized companies. Then your life would take place at trade shows as a salesperson instead of in a service van at new construction sites. A completely different job that requires different skills.

Luftikuss22 Oct 2018 07:54Hello Mottenhausen,
For controlled residential ventilation systems, this is exactly what we do—starting with North Rhine-Westphalia, since for me this is initially a part-time activity. It can be expanded later on, but it also needs to remain affordable for the customer.
Yes, there are disinfectants that have a natural scent, which lasts a maximum of about an hour. After that, it dissipates. The customer can decide whether they want that or not. I have spoken with many companies that install controlled residential ventilation systems, and none offer a really effective cleaning solution. Moreover, these companies don’t have the time to provide such services.
For example, I installed my own system myself, and I am definitely not the only one doing so.
From 2019 onwards, according to the EU directive, only passive houses are to be built. Therefore, more and more controlled residential ventilation systems are being installed. So this is a constantly growing market.

The fact that exhaust air and supply air are not mixed, and therefore the supply air is not “contaminated,” contradicts your statements but is subtly ignored.
In the end, a problem is supposed to be solved that does not exist or is only very minor.

In the end, a problem is being addressed that either doesn’t exist or is very minor.So a heat recovery ventilator extracts energy, meaning heat, from the exhaust air. Practically, it does this by passing the exhaust air through the unit.
The recovered heat is then transferred to the fresh air. From my point of view, this is also how fine dust particles end up in the fresh air. Otherwise, how do you explain the dust in the fresh air duct, which is naturally very thin like a film? I would say that the fresh air is indeed contaminated.
Take a look at the exhaust air filter when changing it; at least in my case, it is completely full and must be replaced after 6 months.
The filter is supposed to prevent the dusty exhaust air from reaching the heat recovery unit.
