In this video I show why activated carbon belongs on a fresh‑air intake and how pairing it with a basic energy recovery ventilator (ERV) keeps the benefits of ventilation while stripping out harmful gases (odors/VOCs)

We’ve been told that opening windows is enough to clean up indoor air. And sometimes, it is. But not for most people, and not without tradeoffs.

Lüften, the practice of opening windows fully for 15 to 30 minutes a day, is widely recommended as a way to bring in fresh air. But in modern buildings and especially for sensitive individuals, it often doesn’t work the way people think it does.

Are you aware that household products like air fresheners, cleaners, and paints are now a major source of air pollution in cities? In this video, I dive into how volatile chemical products (VCPs) contribute to outdoor pollution, surpassing even cars and factories in many industrialized areas. These products release volatile organic compounds (VOCs), which escape from our homes and react with pollutants, forming harmful particles and ground-level ozone.

This video features a step-by-step DIY installation of an energy recovery ventilator (ERV).

In this video, I'll tell you how my DIY HRV performed long-term, and explain why I eventually chose to buy an energy recovery ventilator (ERV) instead.

I built a heat recovery ventilator (HRV) from only sheets of corrugated plastic and adhesive.

This video will feature a step-by-step fresh air intake system build.

In this video, I'll explain how kitchen exhaust systems work, and how not having one can negatively impact indoor air quality and in turn, health.
