The First Thing You Put in Your Mouth in the Morning – and What's Really on It

What the Bremen Environmental Institute, a TV report on Kabel 1, and a well-known investor have in common: They all came to the same uncomfortable conclusion about German bathrooms

Tomorrow morning. You go to the bathroom. You reach for your toothbrush. You start brushing.

 

A completely normal scene – which you might imagine differently in the future.

 

Because the moment you put the toothbrush in your mouth, the surface of the bristles has already absorbed something you can neither see nor smell.

 

Every toilet flush creates an aerosol cloud of microdroplets. These droplets contain fecal bacteria – including E. coli and enterococci – and rise up to 1.5 meters into the room air at the moment of flushing.

 

Without active countermeasures, they remain suspended there for between 20 and 90 minutes. During this time, they settle on everything left exposed. On the soap dispenser. On the towel. On the toothbrush.

 

This is not scaremongering. This is physics.

 

And it's the starting point for a question that surprisingly few people ask themselves: What can we actually do about it? 

What happens in your bathroom after every toilet flush – minute by minute

 

Here's the exact sequence of events in an average German bathroom without active odor neutralization:

 

0–2 Minutes: The aerosol particle cloud rises from the bowl. The standard fan – if present – begins to react. It exchanges room air but does not extract particles at the source. The cloud spreads horizontally.

 

2–8 Minutes: Particles settle on surfaces within a radius of up to 1.5 meters. Toothbrushes. Towels. Contact lens cases. The next user enters the room.

 

8–25 Minutes: Remaining particles stay suspended. Anyone entering the bathroom and breathing normally inhales these particles into their respiratory system. The fan is still working to improve the situation.

 

After 25 Minutes: Only now does the concentration normalize – assuming there is adequate ventilation.

This doesn't happen once a week. It happens multiple times a day. In every household. Unnoticed.

Why air freshener doesn't solve the problem – but physically worsens it

 

At this point, the vast majority reach for the solution found in every drugstore: room spray, toilet rim blocks, fragrance diffusers.

 

The Bremen Environmental Institute – one of Germany's leading research institutions for indoor air quality – has investigated the effect of commercially available air fresheners on actual indoor air quality. The result is clear:

 

Aerosol room sprays do not remove odor molecules or biological particles from the air. They mask odors with more intense odors. Olfactory perception changes – air quality does not.

 

Furthermore: The compressed air blast from spraying actively disperses already suspended particles throughout the room. Anyone who uses room spray after going to the toilet is not carrying out a hygiene measure from a physical point of view – but the opposite.

 

The institute also points out that synthetic fragrances release volatile organic compounds (VOCs) into the indoor air, which, if inhaled regularly, can cause headaches, mucous membrane irritation, and allergic reactions in sensitive individuals.

 

In summary: You have a hygiene problem. You reach for the standard solution. The standard solution makes it measurably worse – in two different ways at the same time.

The Real Problem: All Previous Solutions Tackle the Wrong Issue

 

This is the fundamental design flaw that permeates all common bathroom hygiene products.

 

Air fresheners, toilet rim blocks, plug-in air fresheners, ozone devices, ceiling fans – they all have one thing in common: they react to odors and particles that are already in the room air.

 

This is reactive combat. One waits until the problem has arisen – and then tries to manage it. With limited success, as the experiences of millions of households show.

 

The logical counter-question is: What if one prevented particles from entering the room air in the first place?


 

This is not a theoretical concept. It is the basic principle behind the technology that the AirCube employs.

The Technology: Three-Phase Ionization

 

The AirCube does not use activated carbon. Not fragrances. Not passive filtering.

It uses active ionization – a three-phase process that does not filter odor molecules, but destroys them at a molecular level:

 

Phase I – Ionization: The device directs millions of positively charged ions directly into the toilet. These ions react with odor molecules and break down their molecular structure through oxidation.

 

Phase II – Filtering: The broken down odor molecules are passed through the AirCube's specially designed filter and neutralized without residue. What leaves the filter is chemically neutral air.

 

Phase III – Cleaning: The same oxidation process that destroys odor molecules simultaneously eliminates harmful microorganisms and impurities in the toilet. Automatically. After each use.

 

A comparison that makes the dimension of this process tangible: The oxidation power of the positively charged ions is more than 3,000 times that of chlorine. Chlorine is considered one of the most effective disinfectants in the industry.

 

And this entire process takes place before odors reach the room air. Not after.

What the Bremen Environmental Institute says about this process

 

The functionality of the AirCube has been officially tested and certified by the Bremen Environmental Institute – an accredited testing body for indoor air quality and chemical pollution in residential areas.

 

This is not a marketing statement. It is an external, independent confirmation that the process delivers on its promise: the complete neutralization of toilet odors without the use of chemicals or fragrances.

 

For all who make decisions based on verifiable data: This certification exists. It was issued by an institution that has no commercial interest in the product.

Kabel 1 was there – from the very beginning

Kabel 1 closely followed the founding phase of the Berlin start-up Bellaria and the entire development of the AirCube. The broadcast report provides insights into the product's genesis – from the initial idea to market readiness.

This is not a retrospective press release. It is documented coverage by a public medium throughout the entire development process.

Carsten Maschmeyer – and what his investment means

On September 8, 2025, Bellaria founder Giuseppe Leo appeared on "Die Höhle der Löwen" (Shark Tank).

 

The result: A deal with Carsten Maschmeyer.

For those familiar with Maschmeyer's investment principles: He invests in products with a real, measurable problem, a technologically superior solution, and a market large enough to justify scaling. He does not invest in good ideas. He invests in proven functionality.


 

The fact that he made a deal for the AirCube is not a recommendation in the classic sense. It is a due diligence-based capital decision – with everything that says about the actual substance of the product.

 

What users report

 

 

"I'm an engineer. I wanted to understand the mechanism before buying. Ionization as an active destruction of odor molecules – that's a different approach from anything I knew before. Three months in operation. Works precisely as described. No filter changes, no repurchasing, no hassle." — Thomas R., 47, Hannover

 

 

"I was skeptical – because I've tried everything in this category. Scented sprays, toilet blocks, an ozone device. None of them solved the problem, they only postponed it. The AirCube works differently. You notice that after two days." — Andreas M., 53, Stuttgart

 

 

"What convinced me: the certification by the Bremen Environmental Institute. It's not the manufacturer saying it works – but an external institution that has tested it. That's enough of a reason for me." — Dr. Sabine K., 44, Frankfurt

What this means for your bathroom – in concrete terms

 

From the moment the AirCube is operational, the routine in your bathroom changes fundamentally:

Ionization starts automatically. No manual operation required. Odor molecules are broken down at their source – before they reach the room air. The toothbrush on the shelf remains what it should be: clean.

 

No spray. No stone. No diffuser. No filter change. No consumables to repurchase. The AirCube's filter system is designed for durability – a purchase, not a routine.

 

The device is hung on the toilet rim using an Easy Click-In bracket. No tools. No drilling. No installation.

For those who don't equate hygiene with fragrance
