A DIY Ventilation Solution for Renters

Sotirios Papathanasiou2 Comments

Renting an apartment often means limited control over modifications, especially when it comes to essential systems like ventilation. Poor indoor air quality can significantly impact health and well-being, but drilling holes for traditional ventilation systems is usually out of the question. This article presents a simple, affordable DIY project using a standard air purifier to bring fresh, filtered air into your rented space without any permanent alterations.

The Problem: Stale Indoor Air and Renting Restrictions

Old apartments but also modern, energy-efficient apartments can sometimes suffer from poor ventilation, leading to a buildup of indoor pollutants like CO2, volatile organic compounds (VOCs), and particulate matter. While opening windows is a simple solution, it’s not always practical due to weather, noise, or outdoor air pollution. Renters often face the added challenge of not being allowed to make structural changes, ruling out traditional ventilation installations.   

The DIY Solution: Air Purifier Ventilation

This project uses a standard standalone air purifier in a novel way to introduce fresh, filtered outdoor air. The key components are:

  • A Standard Air Purifier: Choose one with a HEPA filter for particulate matter and a carbon filter for gases. Programmable models are highly recommended for automation.
  • Flexible Tubing and Window Adapter: These connect the air purifier’s intake to a slightly opened window. You can find suitable tubing and adapters at most hardware stores for around €15.

Heart Month: Understanding the Link Between Air Pollution and Heart Disease

Sotirios Papathanasiou1 Comment


February is American Heart Month and Saint Valentine’s Day, a good time to raise awareness about cardiovascular health. While many factors contribute to heart disease, air pollution is a significant and often overlooked risk factor.

The Link Between Air Pollution and Heart Disease

Air pollution is a complex mixture of gases and particulate matter, some of which are particularly harmful to human health. When we breathe in polluted air, these particles can enter our bloodstream and trigger a cascade of negative effects on the cardiovascular system.   

  • Inflammation: Air pollution can cause inflammation in the blood vessels, which can lead to plaque buildup and hardening of the arteries.   
  • Blood Clots: Exposure to air pollution can increase the risk of blood clots, which can lead to heart attacks and strokes.   
  • Arrhythmias: Air pollution can disrupt the electrical activity of the heart, leading to irregular heartbeats.   
  • Heart Failure: Long-term exposure to air pollution can weaken the heart muscle and contribute to heart failure.

Air Quality Data & Ownership

Sotirios PapathanasiouLeave a comment

In an age where information is power, the question of who owns the data generated by air quality monitors and sensors has become increasingly important. This is especially true for air quality monitors that provide crucial insights into the air we breathe. While these devices offer valuable information, users should be aware of potential issues related to data ownership and accessibility.   

The Risks of Changing Terms and Closed Systems

In some cases, companies have sold air quality monitors with “unlimited” data storage, only to later change their terms of service and require users to pay for continued access to their own data. This bait-and-switch tactic leaves consumers feeling betrayed and exploited, as they are forced to pay for something they thought they already owned.

Alveolar Sacs and Particulate Matter: A Deep Dive into Respiratory Health

Sotirios Papathanasiou1 Comment

The respiratory system is a complex network responsible for the vital exchange of oxygen (O2) and carbon dioxide (CO2). At the heart of this system lie the alveoli, tiny air sacs where this gas exchange occurs. However, these delicate structures are also vulnerable to the intrusion of harmful particles, which can have serious health consequences.   

The Journey of Inhaled Particles

When we breathe, we inhale a variety of particles, including dust, smoke pollutants, and pathogens. The size of these particles plays a crucial role in determining how far they travel into our respiratory system. Larger particles are typically trapped in the upper airways, while smaller ones can penetrate deeper into the lungs.
