Airmedic Pro 4 Series (Formerly the 4000 series)

If you have occasional pollutants in your home or office for a given space of 1,200 sq. ft. based on an 8 foot ceiling, then AllerAir's Pro 4 Series is the right fit for you. If you are still looking for a portable and lightweight air filtration system for residences and offices but with a larger carbon treated filter that can clean larger spaces of up to 1,500 square feet based on an 8 foot ceiling, then you may be interested in our Pro 5 series air filtration unit.

To help you choose the right AirMedic Pro 4 air purifier, we need to learn quickly what the carbon blends mean. The choices of activated carbon are Exec Blend, Vocarb Blend and Custom Blend

  • Our Exec carbon filter is our general purpose blend, ideal for trapping a wide range of airborne chemicals, gases and odors
  • The Vocarb carbon is our booted blend, offering a more aggresive removal of hard to trap airborne chemicals, gases and odors. This blend is best suited for newly renovated environments, unknown contaminants and/or formaldehyde.
  • Maybe you have an unusual dilemma. Let us customize the perfect carbon blend for your solution. 

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
