Winix Plasmawave 5300 air cleaner review

The Winix Plasmawave 5300 removes odors and indoor air pollutants in 3 stages: a pre-filter, HEPA filter, and the Plasmawave ionizer. It removes pollutants without producing ozone or other harmful by products. The air sensor automatically adjusts the fan speed in reaction to the air quality so there is no need for a remote control. This air purifier is for large rooms up to 350 square feet. It is Energy Star approved and comes with a 1 year warranty from the manufacturer.

It has an auto mode that automatically adjusts to the air quality in the room. The ionizer helps break about chemical-vapors, allergens, odors, and other air pollutants to completely eliminate them from the room.

The fan has four speeds including a turbo mode for high performance and a whisper mode for constant use. The sleep mode dims the lights on the machine and slows the fan so there is no sleep disturbance.
