Winix Smart Zero 4-Stage Air Purifier Black 5520
Create a cleaner and safer home environment for your family with the Winix Smart Zero 4-Stage Air Purifier. This innovative unit uses a fine mesh pre-filter, carbon deodorisation, and True HEPA filter to conveniently purify air in rooms up to 99m². The hospital-grade True HEPA filtration captures 99.99% of allergens and viruses, while PlasmaWave technology safely neutralises bacteria and stubborn household odours. Managing your air quality is also easy thanks to its intelligent smart sensors and seamless Wi-Fi connectivity via the Winix Smart app, Alexa, or Google Home.

We may allow change of mind returns if your product is in ‘new’ condition. It must be unopened, undamaged, and unused and returned to us within 30 days of the product being delivered to you. A $15 restocking fee which includes the return label is deducted per item returned. Once the item has been received and assessed by the returns team, we will proceed to refund the amount of the product, (excluding the original delivery charges).
Change of mind refunds for clothing, footwear and accessories will only be accepted if items are returned unworn, unused, and in saleable condition with the original tags attached. They must be returned in their original packaging, including sealed boxes, plastic bags, and shoe boxes.
