Winix 5500-2 Air Purifier - 360 Square Feet and 70 W

Winix 5500-2 Air Purifier is a black tower unit with a four-stage filtration system, a remote control, and a room rating of 360 square feet. Its tall profile fits medium rooms, while the front panel opens for filter maintenance.

Four-Stage Filtration System

The system combines a washable fine-mesh pre-filter, a washable AOC carbon filter, a True HEPA filter, and PlasmaWave technology. Winix says the True HEPA filter captures 99.99% of airborne allergens, contaminants, and pollutants as small as 0.003 microns in independent laboratory testing.The four-stage filtration details describe how the washable carbon element handles household odors and volatile organic compounds.

The manual lists one pre-filter, one washable AOC carbon filter, and one True HEPA filter in the package. The carbon filter can be washed, while the True HEPA filter cannot be washed and uses Filter H, SKU 116130, as its replacement part.The user manual lists the included filters and replacement part.

Room Size and Controls

The US manual specifies 15 inches in width, 8.2 inches in depth, and 23.6 inches in height. It lists a weight of 15 pounds, AC 120 V at 60 Hz, and a maximum power rate of 70 W.The US specifications and warranty are stated in Winix documentation.

The unit provides Auto and Sleep modes, four manually selected fan speeds, a timer with 1-hour, 4-hour, and 8-hour settings, and a color-coded air-quality indicator. Its smart sensor detects odorous gas, and Auto mode adjusts fan speed according to the detected air quality.

US Status and Practical Fit

Winix discontinued the 5500-2 in the United States and Canada in 2025, with the Winix 5510 serving as its successor. The 5500-2 remains a relevant reference for existing owners and remaining US retail inventory, especially because Winix lists replacement Filter H for the model.

The device suits a medium room with a 360-square-foot rating and uses a physical remote rather than Wi-Fi or an app. Its 15-pound body and 70 W power rate keep the specification set straightforward, while the washable carbon filter reduces the number of disposable filter components.

Verdict for Medium Rooms

Winix 5500-2 is best placed as a medium-room tower purifier for bedrooms, living rooms, and home offices within its 360-square-foot rating. The main limitation is its discontinued US status, while the two-year limited warranty and replacement-filter designation support current owners.
