An Important Alert for Our Chinese Customers

We have identified a number of websites that are selling and marketing fraudulent AllerAir products and replacement filters. Please note these products are not manufactured by AllerAir Industries and are not made in Canada.

All AllerAir products are manufactured in Canada with specific quality assurance checks for your health and safety, including new filters. We caution customers that unauthorized products may contain recycled filters with contaminants, inefficient motors for the size and use of the units and other serious defects which may compromise your health and air quality.  

Each AllerAir unit is also specifically marked with serial numbers and other identifiers for warranty purposes. Units without these security features that correlate to our records will not be serviced or warrantied by AllerAir. Units with counterfeit markings shipped to us for repair may also be seized under Canadian  law.

These are some of the sites identified as misrepresenting product with the AllerAir name, logo and labeling:

About Carbon Blends

Our standard “EXEC” carbon blend has a very large internal surface area and works exceptionally well for a wide range of air pollutants. 


The “Vocarb” carbon blend is our most recommended and best-selling specialty carbon blend. Vocarb stands for Volatile organic compounds or VOCs and this include a variety of chemicals that can cause a range of health problems including shortness of breath, headaches, fatigue, nausea, dizziness and eye, nose, lung and throat irritation. Some VOC's are suspected to cause cancer in humans and have been shown to cause cancer in animals. The long-term health effects caused by VOC's would depend on the concentration and length of exposure.


Some chemicals adhere better to different types of carbon materials and carbon blends. Over the years we’ve sourced and developed over 40 carbon blends. If you have an odor or chemical you need to remove, we have a blend to target it
