WINIX ZERO-S

I did a lot of research before buying this and I'm glad I did, I have severe heyfever and this unit has helped tremendously. The reason I picked this particular purifier is: 1. It has a very effective sensor which means you can leave it on all the time and it will spin up and down automatically to remove any pollutants present as and when required. This means it's quiet and energy efficient and just gets the job done without you even knowing it's there. 2. When you turn your light out at night, it automatically goes into nighttime mode, turning off the majority of it's lights (and dimming the remaining two) whilst slowing the fan down to the point where it is virtually silent (I can't hear it anyway). 3. It has a proper carbon filter not a impregnated sheet like many other machines. 4. It's filters are in the correct sequence to get the most life out of them and it also has an easily removable, cleanable (like a tumble dryer) pre filter to protect the main HEPA and carbon filters. Many competitors omit this reducing filter life. 5. Its just the right size. Big enough to be able to run very quietly during normal operation and clear a room quickly if you had to (for example burnt toast setting off the smoke alarm) and yet not too big to be crazy expensive. The consensus seems to be if you need a more powerfull unit than this you are probably better off buying two units than a bigger single one. 6. It is properly certified and Winix have a good reputation for building solid high performance machines which are great value. The thing that stunned me the most was just how sensitive and quick reacting it is. My partner had been in the garden and walked in the room and it pretty much instantly detected the pollen coming off her clothes and ramped up for a few seconds to clear the air then span down again. If I had to say anything bad about it, it's that it doesn't have a way to run in auto mode without having nighttime detection on. Because it's so hot at the moment we are closing the curtains which is sometimes leading it to prematurely go into night mode.

Do not buy the smaller air filters. I have A1AD, which is basically COPD. I'm very sensitive to pollution now, both outdoors and indoors. I used to have an older 2014 model plasma wave and it's still working strong but I couldn't take it with me when I moved. Being broke from moving I decided to buy a cheap £30 air filter with apparently HEPA and carbon filter (V important). However it became noisy, and the carbon filter got saturated very fast as there wasn't much of it. Aka waste of money and my health suffered. This is expensive but, like the last one I bought, as soon as I plugged it in, fresh beautiful oderless air. I'm not sure how effective the air monitor is compared to my older model it doesn't scream red and blow like crazy when I fart or anything, kinda disappointing. But it works and the design is nicer, smaller and more user friendly when changing filter or moving it. It's also quieter. This is a top piece of equipment. Looks it and feels it. The blue light also goes off at night and you can turn off the plasmawave for germs. Practically 0 noise even on normal mode. Very pleased.

The sleep mode is silent. It still does the job, but with my dust allergies I prefer to have it on a bit more powerful during the night. So I have it on setting 2 or 3. Setting 4s sound is not noticeable during the day but at night its probably too loud to sleep with on the full power. But even with full power, it's quieter than a floor or ceiling fan. If you choose automatic setting, which is brilliant, then at night, when you turn your lights off, its sensors pick this up and it goes to sleep mode (the machine doesn't go to sleep like a computer, it just goes to the lowest setting which is silent, plus the indication lights turn off so there's no distractions). The sensors are amazing on this machine. Red lights is when the air is bad. Then amber which is still bad in my opinion. Then it goes to blue (why not green? Lol traffic lights? Lol) . Now this is where the machine really shows how good it is. So your sat in the living room and the machine is on automatic setting, it's cycled through your dusty room and it's gone to blue. Pure air. But if you get up and walk into the kitchen, walk past it, open a door, breathe near it lol it senses it straight away and goes to amber and starts purifying again. Because the single bit of dust you've created by brushing past or treading in the carpet or opening a door , that dust has made its way to the machine within seconds. It's a really clever price of kit. It's helping me cut down on the dust in my home. And aesthetically it's very pleasing to the eye. It's a really good looking unit. It looks like you've spent a few hundred pounds on it, which you have. And it's worth every penny. I'm very happy with it.

Owned for only 2 days so make of my review what you will. Appearance is cosmetically pleasing. Looks modern, high tech, and fits in well with my decor, furnishings etc. Noise is whisper quiet. On Auto the air quality it senses in my house is blue for good. So the fan hasnt kicked in above 2. I barely hear it. On night mode its barely audible and I have had it in my bedroom with no disturbance at all. Ease of use is simple. It defaults to Auto on power up which senses air quality and adjusts fan speed accordingly. The colder air blows from the top so its not blasting from the front. At night if its dark the optical sensor turns it to night mode, the main lights go off and it runs at minimum speed. You can barely hear it. If the TV is on then you wont. Its quite large so isnt light, nor too heavy. It has a handle and well designed. I trust its effective but after only 2 days I can only speculate as it feels and looks a quality product. At the time of purchase this new Zero S isnt on the Winix website yet. Seems a bit odd? Overall satisfied with my purchase. Thinking of buying another for upstairs.

The Winix Zero S Air Purifier is a mid-to-high-performance home air cleaning unit designed to handle spaces up to around 100 m², making it suitable for living rooms, bedrooms, and open-plan areas. It uses a four-stage filtration system with a pre-filter, activated carbon layer, a True HEPA filter that captures tiny particles like dust and pollen, and Winix’s PlasmaWave technology that aims to neutralise viruses and bacteria without producing harmful ozone. The unit also includes automatic mode and sleep mode features that adjust fan speed based on air quality and reduce noise and light output at night, which many users find convenient for everyday use. Air Appliances +1 On the other hand, while the Zero S generally receives positive feedback on its performance and quiet operation, there are varied user experiences regarding the accuracy of its air quality sensor and how it displays real-time readings, with some owners reporting inconsistent indicators. Like many HEPA purifiers, its effectiveness also depends on room placement and regular filter maintenance, and it doesn’t offer advanced smart integrations such as app control. Overall, it’s a capable unit for improving general indoor air quality but may not satisfy those looking for fully automated or premium smart features. reddit.com

I purchased the Winix Zero-S Air Purifier in June 2024 to help manage my severe hay fever. Initially, the unit worked well, but by January 2025—just 8 months later—the light began blinking constantly. We maintained the machine properly, regularly cleaned the filter, and even purchased a new replacement filter in March 2025, but the problem persisted. Customer service eventually agreed to a replacement. However, the process was slow and frustrating—it took nearly 3 months to receive the new unit, despite explaining the urgency during hay fever season. We even paid for the return postage ourselves. The replacement unit has been a major letdown. It fails to clean a small 6m² bedroom effectively and never displays the blue “clean air” light, even after running for hours. In fact, I had to turn it off at night because the airflow made my symptoms worse. We live in a clean, dust-controlled environment, so this performance is unacceptable. The original machine was far more effective. This entire experience—early product failure, poor after-sales service, and an ineffective replacement—has been very disappointing. Given the cost of the unit, the extra filter, and return postage, I expected much better quality and support. I cannot recommend this product or brand and feel let down by what was initially a trusted name.

Bought due to my 10 month old and I having allergies. Moved into a new house felt like there was so much pollen, dust and smell of smoke from previous tennant that no amount of cleaning could shift, me and baby were up all night every night she was coughing to the point of vomiting for the past two months! After extensive research I bought the WINIX and I can not tell you the difference it has made we have had it for 5 days and she has slept through the night for the first time every single night no coughing at all. Can feel a massive difference in air quality and could not recommend enough!

Works great, very quiet in nighttime operation and I've had it on 24/7 since I bought it with zero issues. However, there are no filter replacements available for delivery to Ireland and this for me is a real pain and hence the removal of 2 stars, it would otherwise be a 5 star review but I'm essentially stuck with a dead and unusable product once the filters need to be replaced.

I did extensive research to find the most quite, medium sized air purifier and landed on this. However, on 'sleep mode' my specific one makes a tone of noise. I've resorted to running it on the first/second fan speed which I can barley tell its running at night still. I'm giving them the benefit of the doubt that this specific one out of a couple thousand is defected on 'sleep mode'. On the other hand overall I'm very happy with the build of this purifier, It's built to last and the filter system is extremely easy to replace/clean. Also this purifier has the washable activated carbon filter over the disposable one which is a big bonus. To top it off the design is nice and modern but not too modern so this guy should fit classic style homes, modern ones and the in-between. I would recommend this to a friend if I was compensated for the defect, allbeit I haven't chased up amazon that hard yet though.

This filter informs us our air quality in Dubai is not good, we keep doors and windows closed because of it. Even when fitted in a somewhat contained corner, it still detects particles fairly quickly when the door or window is open. Also when cooking, especially oil frying, this filter indicates the particles. I believe we need 2 more throughout the house to obtain complete 'clean' air. It has a big filter with activated charcoal, but does not really remove odors from cooking or other sources.

Pros: - not a s loud as many people say even on highest setting - removes the smell of dampness well Cons: - doesn't deal with dust as hoped. Therefore, allergies same as without it - no dehumidification I have no way to measure pollen and never smoke at home so didn't try that either
