At present, Parry Paint's negative ion paint uses high-quality mineral materials that are naturally charged in nature. In addition, it uses its own PURITI+ formaldehyde removal technology and an air purification circulation system composed of nanodiatom technology. Effectively purifies air odors, and because the product's high-quality mineral materials can react with water molecules in the air, it can continuously release oxygen negative ions. It has been experimentally proven to be effective.
