Review: Amazon Air Quality Monitor | Worth it?

Sotirios Papathanasiou4 Comments

Amazon, the big and multinational technology company which focuses on e-commerce has decided to enter into the game of indoor air quality in a rather surprising way. I will explain why in a minute.

In November 2021, Amazon announced that they will build and sell an air quality monitor. I was the first to discover that the monitor will feature the brand new SEN54 Node by Sensirion which is an all-in-one sensor solution for the measurement of particulate matter, volatile organic compounds (VOCs), humidity, and temperature. Amazon offered a great deal to Sensirion because the Node isn’t available to others yet. 

By the way, back in 2018, I contacted Amazon for the development of an Indoor Air Quality Monitor, but they weren’t aware of the Indoor AQ situation then, however, in the pandemic they grasped the business opportunity. Indoor AQ is a huge deal and even though they didn’t collaborate with me (no hard feelings).

In & Out – Airthings & Airly

Countless times, I have said that it is very important to monitor our indoor air quality side by side with the outdoor air quality. A collaboration between Airthings and Airly brought the best of both worlds, ambient air quality and indoor air quality monitoring in one place. Unfortunately, this solution is available only to the business customers but we can always hope that the demand will drive the feature to the consumer clients as well.

Why in & out AQ monitoring is important?

Our indoor air quality depends on many factors like building material, furniture, and indoor activities (cooking in a home or printing documents in an office, the perfumes people wear, etc). All of these factors will determine indoor air quality from the inside but indoor air quality is subject to outdoor conditions too. Vehicle traffic, marine traffic (in case you live near a port), wood-burning, industrial activities in the area, and wildfires are some of the reasons that will affect indoor air quality as buildings need to breathe or ventilate if you want.

Someone may ask what more they can offer to an already saturated market of air quality monitors. The answer is simple: Experience! TSI Incorporated is a USA-based company with more than 60 years of experience and knowledge thanks to the 1000 researchers and engineers that work for the company worldwide. They hold more than 50 patents.

Recently, TSI released the AirAssure which is an IoT-enabled Indoor Air Quality Monitor (AQM) designed specifically for buildings that really need to have an in-depth and accurate view of the indoor air quality. The monitor comes in two versions the 4-gas and 6-gas variation. I am going to review the 4-gas AirAssure IAQM that comes with a Formaldehyde, Carbon Monoxide, Carbon Dioxide, and Total Volatile Organic Compounds sensors. Apart from the 4 or 6 gas sensors configurations, all versions come with a particulate matter sensor and a temperature/humidity/barometric pressure sensor. Also, a new CO2 and VOC model will be released this autumn.
