Review on TRUSTECH 215ft² Air Purifier for Home, H11 HEPA Filter, Removes 99.97% Allergens, Smoke, Pollen, Pets Hair, 20DB Desktop Air Cleaner, 3-Stage Filtration, Air Quality Sensor for Office, Bedroom (White) by Colleen Jackson

Fantastic gift for friends. The price is very high to buy a few products and we all love its design. I am happy with this purchase. Since my friends told me they use it every day and both work very well.1. Powerful This device is equipped with a 3-in-1 filtration system consisting of a True HEPA filter, a pre-filter and an activated carbon filter. This system can effectively remove dust, pollen, pets and pet odors. One of my friends who has a dog said that when she used this air purifier, the smell of pets and the smell of the old building disappeared.2. There is no noise. The seller stated in the description that this product has a sleep mode. My friend has insomnia. Before getting and using these air purifiers, she was worried that she would not be able to sleep well because of the noise. But even at night they hardly heard a sound. I am very happy with this purchase. You love my gift so much. Finally, I am satisfied with their customer service. Before purchasing I asked a few questions and they answered me very quickly. They promised me that if I had any questions or problems in the future, they would send me a new replacement soon. All in all, you won't regret the purchase.
