QiHome® Air Study: Does It Protect Cells? Lab Results

The QiHome® Air study is a lab study on human cell cultures, published on June 1, 2026. Next to the device, nerve cells closed an artificial gap much faster within 10 hours. The gap that remained was less than half the size of the gap without the device, which the study reports as 53.3 percent better regeneration. Under strong cell stress, more nerve cells survived, and certain immune cells produced 16.4 percent fewer oxygen radicals. Most people who see the study for the first time ask one thing: what does this mean for me and my home? Four explanations help. What a gap experiment says about regeneration. How strong the stress in the lab was. Why the work concerns the peripheral nervous system. And how a distance of 2 meters (about 6.6 feet) in the lab fits a device designed for a radius of up to 160 meters (about 525 feet). The short answer: the study measured a clear, repeated effect on cells. There is no study of the QiHome® Air in people yet.

What did the QiHome® Air study examine?

An in vitro study is an experiment on living cells outside a body, in a culture dish kept at 37 °C (98.6 °F). The QiHome® Air study comes from Peter C. Dartsch of Dartsch Scientific GmbH in Dießen am Ammersee, Germany, and appeared in the journal “Neurodegenerative Diseases: Current Research” (Dartsch 2026).

The study used two cell types. The first is the human nerve cell line SH-SY5Y. The second is the cell line HL-60, whose cells mature in the lab into functioning immune cells of the blood. Both lines come from the Leibniz Institute DSMZ cell collection in Braunschweig, Germany (Dartsch 2026, section 2.2).

Experiment	Cells	Time next to the device	Result next to the QiHome® Air
Gap closure (regeneration)	SH-SY5Y	10 hours	Remaining gap 11.8 instead of 25.2 percent of the area
Oxidative stress	SH-SY5Y	24 hours	34 percent more living cells at 1 mM hydrogen peroxide
Immune cell metabolism	HL-60, matured	last 3 days of maturation	Baseline activity 20.7 percent higher, radical production 16.4 percent lower

Values from Dartsch (2026), sections 4.1 to 4.3. All differences are significant at p ≤ 0.01, tested with the Wilcoxon-Mann-Whitney test.

All three measurements point in the same direction. That is the most important finding of the paper, more important than any single number. The full study and the original PDF are on the QiHome® Air study page.

How was the QiHome® Air experiment set up?

A control group is a comparison sample that is handled exactly like the test sample, only without the factor under study. In the QiHome® Air study, test cells and control cells sat in two identical mini incubators at 37 °C (98.6 °F) in the same culture medium (Dartsch 2026, section 2.1).

The QiHome® Air stood about 2 meters (about 6.6 feet) from the incubator with the test cells. The control cells were in a different house, about 1.5 kilometers (about 0.9 miles) away in a straight line. Dartsch gives the reason for this distance in the paper.

“The mini incubators were located in two houses about 1.5 km linear distance apart so that a mutual influence between the cell cultures could be excluded.” (Dartsch (2026), section 2.1)

The large distance matches how the device is built. According to the Qi Blanco product page, the QiHome® Air is designed for a radius of up to 160 meters (about 525 feet). A control in the next room might well have been exposed too.

The experiments ran over several weeks. Dartsch measured gap closure in 4 independent test series with 3 replicates each, and the other two experiments in 3 independent series each (Dartsch 2026, sections 2.3 to 2.5). Independent means on different days and with freshly prepared cells. A lucky hit on a single lab day is therefore largely ruled out.

What does 53.3 percent better cell regeneration mean?

Cell regeneration in this experiment means that cells repopulate an empty area by migrating and dividing. Researchers measure it with a gap experiment, known in the lab as a migration or scratch assay. Liang, Park and Guan describe the method in one sentence.

“The in vitro scratch assay is an easy, low-cost and well-developed method to measure cell migration in vitro.” (Liang, Park and Guan (2007), Abstract)

In the QiHome® Air study, the gap was made without a scratch. A silicone insert with walls 500 micrometers (about 0.02 inch) wide kept a strip free while the cells attached. After the insert was removed, the nerve cells migrated into the gap for 10 hours (Dartsch 2026, section 2.3).

After that, the open area next to the device had shrunk to 11.8 percent, and without the device to 25.2 percent (Dartsch 2026, section 4.1). Next to the QiHome® Air, the remaining gap was less than half as large. This gives the figure of 53.3 percent better regeneration, with a spread of 6.4 percentage points. Image analysis software measured the area at 4 spots per sample.

The 53.3 percent is a relative difference between two remaining areas (Dartsch 2026, section 4.1). The cells did not grow 53.3 percent faster. The figure says that of the gap left open without the device, more than half was already closed next to the device.

What does the hydrogen peroxide experiment measure?

Oxidative stress is a state in which cells produce more reactive oxygen compounds than their own defense systems can neutralize. Labs often reproduce it with hydrogen peroxide, because the substance is itself such an oxygen compound.

A comparison shows how strong the stress in the experiment was. Sies describes 1 to 10 nanomoles per liter as the range of normal signaling by hydrogen peroxide and speaks of damage to biomolecules from about 100 nanomoles (Sies 2017, Abstract). Dartsch used 0.5 to 1.5 millimoles per liter in the culture medium (Dartsch 2026, section 2.4). One millimole is a million nanomoles. A culture medium and a human body are not directly comparable, but the order of magnitude makes the point: the cells were under very strong stress.

After 24 hours, Dartsch measured how many cells were still alive. The measure was the activity of their mitochondria, the power plants of the cell. At 1 millimole, 34 percent more cells were alive next to the QiHome® Air than in the control. At 1.5 millimoles, it was more than 80 percent more (Dartsch 2026, section 4.2). At the lower doses, the study found a small increase that was not significant.

For you, the pattern is this: the stronger the stress, the clearer the difference. In the culture dish, that is what a protective effect looks like when it holds up exactly where it is needed.

What do the immune cell measurements show?

Neutrophils are immune cells of the blood that act as the front line of innate immunity (Dartsch 2026, section 5). For the experiment, HL-60 cells matured into neutrophils over 6 days. For the last 3 days, they sat beside the QiHome® Air (Dartsch 2026, section 2.5).

The study measured two values. The first is baseline metabolism, meaning how active the cells are at rest. Next to the device it was 20.7 percent higher than in the control, with a spread of 8.0 percentage points. The second is the production of superoxide, a reactive oxygen radical that immune cells release in response to a trigger. It was 16.4 percent lower, with a spread of 4.1 percentage points (Dartsch 2026, section 4.3). Both directions appeared in all 3 test series.

The HL-60 line is a standard model for these measurements. Teufelhofer and colleagues call these cells excellent targets for a rapid superoxide test on a microplate (Teufelhofer et al. 2003, Abstract).

What does the combination mean? The cells were more active and at the same time released fewer radicals. The author reads this as an anti-inflammatory effect at the cell level and as a sign of livelier innate immunity (Dartsch 2026, section 5). Both readings refer to cells in a dish.

Why does the study only concern the peripheral nervous system?

The peripheral nervous system includes all nerves outside the brain and spinal cord, for example in the arms, legs and organs. Nerve research has a clear finding on how it differs from the central nervous system.

“Injured peripheral nerves but not central nerves have the capacity to regenerate and reinnervate their target organs.” (Gordon (2020), Abstract)

The gap experiment in the QiHome® Air study measures exactly this capacity to regrow. Dartsch therefore places his model clearly.

“This in vitro model is only related to the peripheral nervous system.” (Dartsch (2026), section 2.3)

The study makes no statement about the brain or the spinal cord.

The choice of cells fits this. SH-SY5Y is a cell line that keeps dividing and has been in lab use since 1970. Mature nerve cells from tissue no longer divide and cannot be grown in large numbers (Kovalevich and Langford 2013, Abstract). A cell line makes experiments repeatable, but it is a model, not a nerve in a body.

What does the QiHome® Air study mean for your home?

Transferability is the question of whether a lab finding shows up the same way under everyday conditions. For the QiHome® Air, it helps to put the study and everyday life side by side.

• Distance: In the experiment, the device stood about 6.6 feet (2 meters) from the cells (Dartsch 2026). According to Qi Blanco, it is designed for a radius of up to 160 meters (about 525 feet). The study did not measure greater distances.
• Duration: The cells were next to the device for 10 hours up to 3 days. At home, it runs continuously.
• Subject: The measurements were made on cells in a dish, not on people.
• Technology: The QiHome® Air uses the same Gitterchip technology as the QiOne® 2 Pro and the QiBracelet®, in the QTA-U-5000 version with a rock crystal as amplifier. According to Dartsch, its system output is about 100 times stronger than that of the QiOne® 2 Pro (Dartsch 2026, section 2.1).
• Funding: Qi Blanco paid for the study and provided the device (Dartsch 2026, section 6).

Peter C. Dartsch sums up his results in the conclusions of the abstract.

“As demonstrated in the cell-based assays presented here, exposure to the QiHome® Air has beneficial properties that might counteract environmental disturbances leading to neurodegeneration, neuroinflammation and the associated functional disorders in a complex organism […]” (Dartsch (2026), Abstract, Conclusions)

The limit belongs to the result. This is a lab study on cell cultures. It says nothing about how the device acts on a living person, and its model refers to the peripheral nervous system, not to the brain and spinal cord. What it shows is a clear direction, repeated in every test series. The next step would be a repeat in a second lab and an observation of people in their own homes. All of Qi Blanco’s studies are listed in the study overview, and the device itself is on the QiHome® Air page.

Frequently asked questions about the QiHome® Air study

Is there a study of the QiHome® Air in people?

No, not yet. The published research so far was done on cell cultures in the lab (Dartsch 2026). It measures nerve cells and immune cells in a culture dish.

How far was the QiHome® Air from the cells?

Roughly 6.6 feet, or 2 meters, from the incubator with the test cells. The control cells were about 1.5 kilometers (about 0.9 miles) away in a different house (Dartsch 2026, Materials and Methods).

How long did the experiments take?

Gap closure ran for 10 hours and the stress experiment for 24 hours. The immune cells spent the last 3 days of their maturation next to the device. The whole series of experiments took several weeks (Dartsch 2026).

How does the QiHome® Air differ from the QiOne® 2 Pro?

Both use Qi Blanco’s Gitterchip technology. The QiHome® Air works with the QTA-U-5000 version and a rock crystal as amplifier. According to Dartsch, its system output is about 100 times that of the QiOne® 2 Pro (Dartsch 2026, experimental setup).

Who paid for the study?

Qi Blanco funded the study and provided the device for the experiments. This is stated in the funding section of the publication (Dartsch 2026, section 6).
