Filtration System

Filtration system on Envion Therapure TPP240 model is extremely powerful. Thanks to the combination of ionization, UV light and HEPA filter this air purifier is capable of removing allergens, pollutants, bacteria, germs, fumes and bad odors.

UV Light is useful in killing germs, bacteria, and viruses. Bad odor, fungi, and mildew will be gone too. It uses photo Catalyst filter to remove chemicals, fumes, and odors from the rooms. The filtration system in this air purifier is powerful to remove air pollutants efficiently in a 200 square feet rooms.

CADR ratings for smoke are 137, dust 132 and pollen 155. These are good ratings which make allergens gone from the room at once. In the end, if you need even more filtration power, you can turn the ionization process on. Ionization will generate negative ions which will bond with airborne particles and in that way make them heavier and bigger. Heavy and big particles are quickly captured by the filter.

Energy Efficient and at The Same Time Luxurious
