StudioAir is a complete range of products developed by AllerAir to ensure a safe and healthy studio environment for artists. Vocarb models feature double impregnated carbon for VOC absorption of all types of chemical toxins in turpentine, acrylics, xylene, spray adhesives and most other paints, cleansers and mediums. These are the models we recommend for most studios. If your studio is in a basement or a very moist environment we recommend a model with a UV element, which will kill molds. All units will get out common dust, and the big 500 and 600 units will do an extremely effective job on pastel dust. If you have allergies this type of filtration system is essential for your health considerations.
