Why Has Indoor Air Quality Deteriorated During The Pandemic?

Last March, as people around the world shuttered into their homes to limit their chance of contracting COVID, an unfortunate side effect began occurring… indoor air quality plummeted.

In fact, air quality monitors around Europe detected that between March and early May, levels of carbon dioxide and volatile organic compounds (VOCs) increased by 15 to 30 percent.

Fortunately, the warm summer months have given many of us a chance to get back outdoors and enjoy the benefits of fresh outdoor air.  But, as the fall approaches, it’s important to think about how to keep our indoor air quality from deteriorating again.

Why did the air quality in our homes deteriorate so much?

  1. Cooking. With restaurants closed and anxiety about the safety of takeout, many people opted to cook all their meals at home. Unfortunately, cooking is one of the biggest causes of indoor air pollution. The pollutants created by cooking can actually be so serious that, according to a recent article in Scope, Stanford Medicine’s publication, they “can cause health problems such as respiratory illness and asthma attacks.
  1. Cleaning products. In the spring, most experts were emphasizing the importance of keeping surfaces disinfected, leading to an increase in harsh cleaning products and overuse of chemicals.  From January to March of this year, the CDC reported a 20% increase in calls compared to the same period last year.
  1. Exposure to other indoor pollutants. The EPA has found that indoor air often has a concentration of two to five times more pollutants than outdoor air. Mold, radon, pesticides, dust, smoke, bacteria, viruses, and various volatile organic compounds (VOCs) all present health hazards, especially when we’re spending so much time indoors.

Can Indoor Air Quality Affect Your Risk Of Covid Complications?

While staying home can be a good way to keep from contracting the virus, if you were to get sick, being exposed to pollutants may make you more likely to be hospitalized for these reasons:

  1. Pollution can cause or aggravate respiratory illnesses like asthma or chronic obstructive pulmonary disease, which may make you more susceptible to the worst effects of lung infections.
  2. People exposed to air pollution are more likely to suffer complications from COVID.

How can we keep our indoor air quality high if there’s another shutdown?

There are a number of steps we can take to avoid another dip in our indoor air quality such as:

  • Ensuring that gas stoves are well ventilated
  • Reducing the use of harsh cleaners and scented products
  • Keeping windows and doors open as much as possible

While all of these measures can help reduce pollutants in your indoor air clean, perhaps the most important step we can take to improving our indoor air quality is to purchase an air purifier. A high-quality air purifier remove pollutants such as dust and smoke from the air.

How Tax is calculated

The amount of tax charged on your order depends on many factors including the following:


  • The identity of the seller
  • The type of item or service purchased
  • The time and location of fulfillment


The shipment or delivery address of your order
These factors can change between the time you place an order and when your shipment is complete. As a result, the tax calculated on your order may change. We display an “Estimated Tax” to be collected at Check Out when confirming an order. The amounts displayed as estimated tax may then be updated later when your order is finalized and completed.


The tax rate applied to your order will be the combined state and local rates of the address where your order is delivered to or fulfilled from. For example, if you live in a state that does not impose a sales tax, you may still see tax calculated on your order if shipped to another state. Moreover, the tax rates applied to your order may also be different for a variety of reasons, such as a shipment to a residential home versus a business address. Also, the total selling price of an item will generally include item-level shipping and handling charges, item level discounts, and gift wrapping charges. If applied at an order level, these charges, may be allocated to the individual items in an order.


If you are ordering from aeris and shipping to a country outside of the US, you may be charged the applicable country tax rate.
