Scientifically Tested & Certified: Alen Air Purifiers Stand Alone To Meet the Highest Air Quality Standards

Recognized by Quiet Mark, Asthma & Allergy Friendly® Certification Program, SleepScore Labs, and ENERGY STAR® for superior performance

Alen, a leading innovator in the air purification industry, today announced its air purifiers have earned multiple prestigious certifications that further validate its position of providing the “best in class” features all air purifiers should have: a 99.9% removal of airborne allergens, maximum energy efficiency, and ultra quiet operation. Alen’s air purifiers have earned certifications from Quiet Mark, the Asthma & Allergy Friendly® Certification Program, SleepScore Labs, and ENERGY STAR®, ensuring its trusted name among discerning consumers who demand high-performance air purification solutions.

“Not all air purifiers meet industry certification guidelines. Alen’s air purifiers do,” said Alen CEO Warburg Lee. "Savvy consumers know us, and we’re pleased that a new generation understands the importance of third-party validation to help make the best decision to ensure the well-being of their families, friends and customers.”

Alen’s top industry certifications include:

• Asthma & Allergy Friendly® Certification – Certified by Allergy Standards and the Asthma and Allergy Foundation of America. Alen’s purifiers are independently tested against strict standards and proven to reduce airborne allergens, helping the more than 100 million people living in the U.S. affected by asthma and allergies annually to breathe clean air. "By removing 99.9% of airborne allergens—such as pollen, dust, and pet dander—Alen’s purifiers help support a cleaner, healthier indoor environment."
• Quiet Mark Certification – Alen’s air purifiers are engineered to deliver ultra-quiet operation, earning recognition from Quiet Mark for providing powerful purification without disruptive noise. Since loud air purifiers are often turned off, this certification ensures Alen’s models help maintain clean air while supporting a peaceful environment. Quiet Mark is awarded to the top 10% to 20% of the quietest products in each category.
• ENERGY STAR® Certification – ENERGY STAR-certified room air purifiers use 25% less energy, on average, compared to standard models, leading to significant cost savings and reduced environmental impact. Most Alen purifiers operate using the equivalent energy of a lightbulb per day or less, with maximum wattages of 55W for the 75i, 50W for the 45i, and 40W for the 35i; however, because Alen owners rarely run their units continuously on the top fan speed, actual energy consumption can be significantly lower than these maximum values.
• SleepScore Validated – Scientifically validated to improve sleep quality, Alen air purifiers create cleaner indoor air for a healthier and more restful sleep environment. SleepScore Labs studies show study participants who used Alen air purifiers experienced improved sleep quality, including falling asleep faster and waking up less frequently during the night. Alen purifiers help mask disruptive sounds, promoting deeper, uninterrupted sleep and enhancing overall sleep quality by utilizing pink noise.

Additionally, the TITAN Innovation Awards named Alen a Gold winner in the 2025 TITAN Innovation Awards, recognized in the Innovation in Technology and Consumer Technology category. The TITAN Innovation Awards received over 3,000 entries from more than 30 countries, reinforcing its reputation as a leading international competition for technology and design excellence. The award reflects Alen’s strong commitment to advancing product innovation and technology.
