Last year alone around 70 million tons of pollution were emitted into the United States atmosphere, these all play a vital part in the air quality across the country. However, some states are worse than others when it comes to air quality. 

Utah has an air quality index of 51.2 with the main reason for its high air quality index being it’s mountainous ranges, causing a pollution build-up near the surface. In contrast, the state with the best air quality was Hawaii with an air quality index of 21.2, sitting well within the ‘good’ air quality index range. Although it’s not all doom and gloom, anything above an index of 50 is considered ‘moderate’ quality***, so nearly all of the US states have good quality air. 

In addition to the air purity data, surveyed 3,000 Americans and asked them to assign a signature scent to the state they currently call home. Participants were asked to select from a range of different smells, but also had the option to add their own. New Yorkers were possibly the most unkind, giving NYC’s aroma as chicken wings and garbage, along with residents in Kentucky who chose Bourbon and horse manure. Virginians chose a state scent of gunpowder, while Georgians decided road works and peaches best represented them. is the number one platform for all dehumidifier and air purifier needs. The platform, founded by Oliver Perryman, was born from the desire to help individuals find the right appliance for them, after discovering that a dehumidifier was the cure to his chronic health complications.

Oliver Perryman, founder of, said,

“Well, 2020 stinks! So we thought it might be fun to find out just what America stinks of in 2020, and decided to ask the people who would know best. I must admit I’m fairly sure that some of these scents are based around stereotypes, but some are quite entertaining nonetheless!

“Less exciting, however, is the thought of air quality index scores going up across the country. We hope that by highlighting the issue of air pollution again, we can bring further awareness of it and remind people that even the smallest change can make a difference. We can all do our part to keep American air pure and safer for all our benefits.”
