After trying this portable purifier, my home feels fresher and healthier .The compact size makes it easy to move from room to room and the silent operation doesn't disturb my daily routine. The scent-free design is perfect for ALLERGY sufferers, and the filter lasts a long time. The only downside is that it doesn't cover a large area, but it's great for personal use. Overall, a great investment for cleaner air in your home..
