When discussing air quality, TVOC has always been the elephant in the room. Despite the importance of the topic, it seems that no one has done a great job explaining what it is and how it's measured, so we want to take a stab at it. Put on your seatbelt, because wrapping your head around TVOC can be a bit of a mental rollercoaster!

To begin our TVOC journey, let’s start off with a simple question: What is TVOC?

Jakarta, Indonesia, 9 July - Air pollution is linked to the loss of an estimated 24,000 lives in Delhi, India in the first half of 2020 despite a strict COVID-related lockdown, according to a new tool that uses live air quality data to track the cost of air pollution in real time. The counter, developed by Greenpeace Southeast Asia and IQAir AirVisual, reveals the impact of air pollution in 28 cities around the world since 1 January, 2020.¹

Outdoor air pollution usually makes all the major air quality headlines. 

A flight is canceled to Delhi because smog is too dense.¹ A red alert for outdoor air pollution is declared due to record levels of dangerous outdoor pollutants.² And nearly 7 million people die prematurely each year from causes linked to air pollution, including heart disease and respiratory conditions.³

In comparison, air pollution in your home or office doesn’t seem like breaking news. 

Understanding the relationship between outdoor and Indoor Air Quality (IAQ) is your strongest weapon against its effects on your health. Your behavior and environment both influence the interaction between indoor and outdoor pollutants, so changing both your habits and your home is crucial to minimizing outdoor air pollution’s effect on indoor air.

With the advent of accurate and reliable low-cost air sensors, economically developing countries experiencing the detrimental human, environmental, and economic impacts of air pollution can establish comprehensive air quality monitoring networks for the first time. Air quality managers in these regions can bypass the traditional notion that air quality data must come exclusively from federal reference method (FRM) or federal equivalent method (FEM) equipment to be useful. Adopting hybrid Air Quality Monitoring 2.0 networks that leverage data from both FRM & FEM equipment and properly-calibrated low-cost sensors allows them to leverage the low costs, high-resolution data coverage, and flexible network design offered by low-cost air sensors to rapidly and cost-effectively establish precisely-located air quality monitoring networks.

Here’s a riddle for you: What is so small that you can only see it from far away?

The answer, of course, is the particulate matter that makes up Beijing smog (or any city’s smog…it’s all pretty small). From a distance, the haze may look dense and thick, but when you’re actually close enough to breathe it, suddenly it’s gone. You can’t make any fine measurements just by looking. It’s not like counting apples in a basket.

We’re forced to make assumptions about the air we’re breathing based on how hazy and grey it looks outdoors, how scratchy our throat feels, or what our phone app says, but we can’t observe particulate matter directly—It’s too small!

The World Health Organization says asthma is the most chronic disease among children. When your child struggles to take a breath, we know you would do anything to take away their discomfort. Helping your asthmatic child live a normal life starts with managing their symptoms and proactively preventing them.

There are several asthma triggers that you can help minimize. It starts where your child likely spends the most time: in your home. Houses are full of allergens like dust mites, pet dander, and other pollutants. The Environmental Protection Agency says the air in our homes and workplaces can be worse than the air in large industrialized cities. Investing in a home air quality monitor will help you understand, track, and improve the air. With the Laser Egg, you can create the cleanest air possible in your house.  

We’ve all seen mold (even if it’s only on the blue cheese we had with lunch), but did you know that you may also be inhaling these tiny organisms?

Molds are a group of fungi often tucked away in warm, humid corners of your home. Despite their stationary appearance, molds have ways of getting airborne and into your lungs. To reproduce, these microscopic fungi release spores into the air. And if the mold dries out, fragments can break off and piggyback on existing dust in your air.

Once these molds enter the air, they can harm both your air quality and your health. Molds can prompt allergic reactions, and some toxic molds can even damage your immune system.

As with any contagious disease, many people are opting to keep their kids home from school or even stay home themselves to prevent exposure. In fact, in many parts of the U.S., schools have been sending students home to prevent the spread of the novel coronavirus. Restaurants and gyms have closed, and only essential businesses continue to operate. With everyone cooped up in the house, one invisible threat remains: poor indoor air quality.
