Customers are impressed with the air quality improvement and quiet operation of this 22" air purifier tower. Many appreciate its ease of use and odor removal capabilities, along with the added benefit of a UV light. However, some customers express concern regarding the filter replacement cost and its coverage area.

    Purchased this item for cleaner air. At first the air was only coming out of the right side, but now it’s coming from both sides. It has my room hot. Might return

  • Failed to meet expectations...

    Functions acceptably for the price paid while on sale ($79). Starts off quiet and becomes loud in a matter of hours. The large vent on the front (output) is deceiving due to the fact it only blows filtered air to the very far left. No air comes from the center or right side at all (3/4 of the vent). Will be returning.

  • Pros mentioned:
    Uv light

    Purchased for our 14ftx14ft bedroom

    Overall happy with the purifier, works good. We like the blue light (an indicator that the UV light is turned on). It makes a good night light, but might be rather bright to some people. Fan noise is average, neither good or bad. We actually prefer the "white noise" it creates, When our old purified died (different brand), it was a little hard to fall asleep because the room was so quiet :)
