Clean air has become a luxury, but it shouldn’t be – Respiray’s mission is to make it accessible to everyone. 



The Respiray stOry.

Our background.

The early days.

Respiray was born in early 2020 when the COVID-19 pandemic struck. Respiray’s first product, the Respiray Wearable Air Purifier, was developed to provide protection from airborne viruses.

The success of this product earned Respiray multiple global awards including the Financial Times and Seedstars Challenge – Top 30 Health Start-Up 2021, the Healthcare Innovation World Cup 2021, and more.


The Respiray Wear A+.

Now, Respiray’s team of scientists, engineers and designers has developed a groundbreaking new device that helps its users fight allergies: Respiray Wear A+. This exciting and unique wearable air purifier eliminates 99.9% of airborne allergens, including pet dander, dust, pollen and mold. The product’s official launch is in January 2023.

Product 2: Respiray Wear A+

According to the World Allergy Organization (WAO), around 400 million people globally are affected by allergic rhinitis caused by airborne pollutants such as pollen, dust mites and mold. In the US, 10–30% of the population suffers from this condition, and this number is only growing. In response to this global health concern, Respiray Wear A+ was created to make it easy for people to reduce symptoms

“Respiray Wear A+ came to life from my own personal struggle with airborne allergies. We optimized the airflow and speed in order to create an allergen-free zone around the users’ faces. It has taken us over 2 years, 117 prototypes, and many tests to launch a product that really works. The product is also lightweight (8.8 oz), easy to use, comfortable to wear and most importantly affordable”.
