Our outdoor and indoor air is filled with particulate matter (PM) that consists of tiny solid and liquid particles that are often invisible to the naked eye. 

But just because we can’t always see these particles, doesn’t mean they aren’t there and negatively affecting our health. In fact, the tinier the particle, the deeper into our bodies it can go! 

The good news is there are steps you can take to improve your indoor air quality.

Be sure to check out this interview to learn more about how everything from your gas stove to your humidifier can be contributing to poor indoor air quality and how you can take steps today to improve the air inside your home!

Indoor Air Quality Monitors – Comparison List 2023 Q3

Sotirios Papathanasiou9 Comments

I know, I know I haven’t updated the list for quite a long time. The main reason is the lack of innovation lately. Also, many companies have shifted their attention and they have removed their products from the market as they don’t have the desirable sales. It doesn’t make sense for new companies to reproduce the same air quality monitors with the same sensors and technology inside over and over again.

I feel the saturation is noticeable nowadays. However, a change is happening and I see it unfolds in front of my eyes.

Anyway, remember there are two tabs; Air quality monitors for consumers (B2C) and for businesses (B2B). As always, I stay away from knockoffs and cheap products. An air quality monitor needs to function properly for 5 to 10 years depending the sensors − gas sensors tend to have a shorter lifespan. Keep in mind, it doesn’t matter how many sensors an air quality monitor has as long as the implementation has be done correctly.

Understanding ASHRAE Standard 241: Control of Infectious Aerosols

ASHRAE, the American Society of Heating, Refrigerating and Air-Conditioning Engineers, is a global professional organization committed to advancing the arts and sciences of heating, ventilation, air conditioning, refrigeration and their allied fields. They have recently introduced a new standard, ASHRAE 241-2023, which focuses on the ‘Control of Infectious Aerosols.’ This new standard is a significant step forward in addressing the transmission of airborne diseases in non-healthcare settings.

The Genesis of ASHRAE 241

The genesis of ASHRAE 241 was during the COVID-19 pandemic, where there was a widespread realization that ventilation rates in non-healthcare settings were not designed to mitigate airborne disease transmission. The pandemic highlighted the inadequacies of our buildings’ ventilation systems, and organizations scrambled to upgrade their systems without a clear understanding of ‘how much’ ventilation was needed.
