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.

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.

Understanding the Link Between Indoor Ventilation and Radon Levels: Insights from Recent Measurements

Sotirios Papathanasiou3 Comments

January marks Radon Awareness Month, a time when public health officials and environmental agencies emphasize the importance of monitoring and mitigating radon gas, a known carcinogen that can accumulate in buildings. Recent measurements taken in my residential setting have revealed a clear pattern linking radon (Rn) levels to indoor ventilation practices, providing valuable insights into how we can manage this health risk effectively.

Short-Term Analysis (7 Days)

The first screenshot presents data for a 7-day period, from January 1 to January 7, 2025. Here, we observe a significant spike in radon concentration on January 5, where levels reached a peak of 114.0 Bq/m³. This short-term data suggests that there was an event or condition on January 5 that caused an unusual increase in radon levels, possibly due to changes in weather, ground conditions, or indoor activities that disturbed the soil or building structure.
