    Overview

    The Winix Zero Compact Four Stage Air Purifier is seriously powerful, going through four unique filtration stages to purify rooms of up to 29.5 meters squared.

    Portable, compact and minimalist in appearance, this air purifier reduces the prevalence of smoke, pollen, dust, pet dander, mould, bacteria, and chemicals. Whilst these aren’t good for anyone, those with allergies, breathing issues or chemical sensitivities can really benefit with this additional protection.

    The Fine Mesh Pre-Filter begins the filtration process, capturing pet dander and hair. Next, the Activated Carbon Filter reduces Volatile Organic Compounds (VOCs) and unpleasant odours that emerge from cooking, pets or smoke. The 360° All-In-One Hospital-grade True HEPA filter then traps 99.97% of airborne pollutants, before the final stage of PlasmaWave Technology, which neutralizes all chemical vapours, bacteria and viruses.

    While this air purifier is packed with advanced filters and sophisticated technology, the user-friendly design makes it a breeze to operate. Enjoy smart features such as ‘Set and Forget’ or ‘Sleep Mode’, and reap the rewards of healthy, fresh air using this Air Purifier from Winix.
    Smart Sensor Technology

    Smart Sensor technology does the work for you, reactively adjusting settings for optimal air quality in the room.

    Set and Forget

    Enjoy the ease of the Set and Forget, an Auto Mode feature which enables continuous filtration, eliminating airborne contaminants and odours.

    Sleep Mode

    Sleep soundly, thanks to Sleep Mode, which operates at a minimal noise level and disables lights whilst purifying air throughout the night.

    Three Fan Speeds

    If you do wish to make alterations yourself, select one of three fan speeds as desired, by navigating the control panel and LED indicator lights.

    Questions & answers

    Dumb question but have to ask. The machine comes with a filter in the first place I assume which could last up to 12 months depending on usage and environment? Mark · 2025-07-28
    Hello Thank you for your product question; it's never a silly question. Yes, a filter is included. It's best to watch the video on our website that demonstrates the filter and how it works. I hope this information will assist you when shopping with us at Appliances Online. Our Sydney-based team is available 24/7 to assist you at Ph: 1300-000-500. Colin Jones, Appliances Online
    Can you please advise where I purchase the filters and how easy are they to change. I assume the machine gives an indication when a filter needs to be removed. Thanks so much Cheers Joan Joan B · 2024-01-07
    Hi Joan, there is an indicator light to let you know when to change the filter. You can purchase them directly from Winix's distributor, AusClimate. You can find them on their website by searching the SKU: GQ-FILTER. Hopefully this helps =) Cheers, Adam from Appliances Online. AdamD, Appliances Online
    ozone* does this 'technology' in your air purifier (Winix Compact 4 Stage air purifier aus-0850aapu) produce ANY ozone at all? Does it have a built-in ionizer or something similar? Thanks, Mark Mark · 2023-05-17
    Good Morning, Thank you for this product question, I have reached out to the supplier to assist with this question, and here is their response this morning: Fortunately, all air purifiers from WINIX with PlasmaWave technology are well below the CARB industry standard, which requires ozone emission concentrations of less than 0.05 parts per million. A number of key air purifier brands have similar technology to PlasmaWave and they should all follow the guidelines of CARB standards I hope this information will assist you when shopping here with us at Appliances Online.
