The PureZone personal air filtration system can be called an effective natural allergy and asthma treatment because in clinical trials it was proven to:

• Relieve symptoms of the nose and eyes
• Improve sleep, allowing the user to awake rested and alert
• Enhance the quality of life

The FDA compliant, randomized double-blind placebo-controlled clinical trial conducted by allergists demonstrated the PureZone system to eliminate >99.97% of allergens in the breathing zone.

As a natural air filtration therapy, the PureZone personal air filtration system delivered better symptom relief than other allergy avoidance products, relief that was comparable to commonly used allergy medications such as antihistamines and nasal steroids.

“Our vigorous double blinded randomized clinical trial showed that the PureZone personal air filtration system is the first air purification device clinically proven to significantly reduce nasal and ocular allergy symptoms together with providing and improved quality of life.”
