At ENVION, we know how important it is to give your family a healthy home environment. After all, we have families too. That’s why we pulled out all the stops when we created our Therapure TPP230H home air purifier – to help you ensure the air your family breathes is free of allergens, pollutants, irritants, and toxins. Our TPP230H tower air purifier is engineered for maximum effectiveness and because of this, we outpace the competition. The TPP230H is a triple-action powerhouse of air purification, using HEPA-Type, UV Light, and Photo Catalyst technologies to deliver maximum protection.
