Waste of money. I bought it to reduce pet hair. Long haired cat and short haired dog constantly shredding. This item does almost nothing to trap fur, even when placed where they spend most of their time. Save your money and electricity. Show details

Efficient and Quiet Air Purifier – The air purifier is excellent, the sleep mode is nearly silent, maintaining a quiet ambiance even on the lowest in fan speed. When fan speed set to turbo, it efficiently clears odours, and it's definitely worth purchasing. Show details

Plug it in and it’s done!! – Amazing!! This machine is very quiet and does exactly what I need it to do - clean the air. I suffer from airborne allergies and have mild asthma. This machine makes my life so much easier now that I’m breathing clean air. Hopefully to be purchasing another one for our bedroom. Show details

I am so glad I purchased this air purifier. My breathing and sleep have improved immensely as my allergy symptoms have almost gone. I love coming home knowing my air is clean. It's so quiet that I can sleep easily with it running and it even has an automatic night mode. Show details

I love it! My daughter and I both have dust mite allergies and asthma. This machine gives me peace of mind. I put it on every night as we go to sleep and use the 1 or 4 hour timer. Can't hear anything. Show details

Very impressed. I bought two, one for upstairs and one for downstairs. It makes the air in the house smell like fresh air. We mainly use it at night while sleeping and have found that the quality of our sleep has improved and we do not wake with allergies. It is also extremely quiet in the night mode. An added bonus is that it eliminates odours… Read more

A good purchase – I have had only had the air purifier for a few weeks, but so far I am definitely glad I made the purchase. The unit is quiet to operate and seems to be helping with my allergies. I will be purchasing another unit for my daughter to replace a cheaper brand of air purifier which doesn't seem to be helping her asthma & allergies. Show details

No regrets – This is my 3rd purchase from ausclimate with all 3 units running and performing well in various sized rooms. Keeps air fresh and clear when using candles and a godsend in rooms that have limited ventilation. They run 24/7 and never skip a beat. Easy to replace filters and sleep mode fantastic where necessary. Absolutely recommend these air purifiers. Show details

works well and is quiet – seems to sense when to speed the fan up and slow down, very efficiently. I open the fireplace door to stoke it or add wood, and it quickly senses the increase in particulates and speeds up. I bought mainly it due to fireplace particulates being bad for health, so this works well and the countdown timer is handy. I only have it on intermittently, as one doesn't open the fireplace door every 10 minutes of course. Show details

Great air purifier! – We purchased 2 air purifiers from AusClimate. This one and a smaller version too. They both work extremely well and we often move the bigger one around the home if we are doing Reno’s or cooking, it really helps with smell, air quality and dust particles. We don’t regret purchasing 2 units as they are good quality def easy to clean & use. Show details ·  1

Great Quality – Purchased for $649.00 in 2022. Very happy with the performance. I can operate it without my glasses because the control pad is intuitive. Does what it should quietly and efficiently. Show details

Much better than the 5 stage and much cheaper too – After a very disappointing experience with the more expensive 5 stage model where the cardboard carbon filter became saturated and started to smell after 2-3 weeks, I decided to try the 4 stage that has a proper carbon pellet odour filter (as any decent air purifier should) and have found it to be vastly superior. It's been 5 months running 24/7… Read more

and the air coming out is still fresh. I remain sceptical about the plasmawave function, as neither my air monitor nor my sinuses can tell any difference between it on and off, but for dust it's a great buy.

Quiet Protection. By Jennifer G. 3 November 2021 – Because of the possibility of mould in our home, we engaged an Environmental Engineer to investigate. She suggested an Air Purifer, favouring the Winix.. The mould is no longer problematic. After our own investigation, and The Choice Magazine recommendation, we bought the Winix brand. With Covid, the presence of our Winix enhanced our feeling… Read more

of protection within the home. The quietness, efficiency and ease of maintenance is amazing. We feel well protected against the possibility of airborne ‘nasties’ and have recommended the Winix to several of our friends. Finally, we would rate your service and customer relationship as Outstanding. Thank You

A staple in our home – I originally bought 1 winix after seeing them at Costco. We have floorboards and a dog so the dust and fur was everywhere and I’d had a bad cough. After a few weeks we noticed the house was less dusty. We have now bought 3 including one in the bedroom which has helped my breathing. Great quite machine. Show details

It’s quiet and so effective – I’ve been using the air purifier since May this year. I suffer from allergies (mostly dust) and this has been really useful in keeping our bedroom air clear. It’s super sensitive. So much so that if I spray dry shampoo on the other side of our very big bedroom, in a matter of seconds the unit senses it and cleans the air! It’s extremely light… Read more

weight which makes it easy to move from room to room. Maintenance is easy too. Just vac the filter every few weeks and replace the main filter each year. Bonus being they send a text to notify (I haven’t had to replace yet but I’m told I’ll be send a reminder)! Highly recommend.

My faith in air-purifiers has been restored – Previously used a Phillips purifier, which was OK but has had to change each filter 2-3 times/year despite regular cleans and resets. Overall, reasonably expensive appliance to maintain. In my search for an upgrade in May this year, I came across Ausclimate on the Sensitive Choice website (not an asthmatic, live in an ancient house with stale… Read more

air) and was shocked by the reviews! I contacted the company the same day and within 2 hours was bringing it home with me like a proud mother. I’ll cut to the chase- it’s brilliant! So quiet, it does a brilliant job spreading the airflow smoothly around the room, even on the lowest setting (which feels cooling and fresh). I even sleep better! I clean the front filter every few weeks and haven’t had to change the HEPA filter yet. I honestly love the Ausclimate Winix - I wish I had one in every room :).

Great product for a healthy house – We purchased the Winix Zero 4-Stage air purifier from Ausclimate as we were getting a lot of dust in our home from a nearby construction site. Since we have been using the purifier the air quality in our home has drastically improved. We have also noticed that the unit removes unwanted odours and in general our house feels cleaner.

is great and it's easy to operate and replace the filters. The unit runs super quiet and has an automatic feature that adjust the fan speed depending on the air quality. I'd definitely recommend this air purifier to anyone wanting to improve the health of their home and family.

Don't even notice it. Great for a small apartment, quiet and does the job – Product is easy to use and assemble. While I don't suffer from any health conditions, my apartment gets so dusty so am always sneezing when the dust piles up. Since I purchased this product, I keep it on 24/7 and noticed I don't sneeze anymore. I think it's also helped me sleep better. Anyway, great product - glad I bought it. Show details

Excellent product – The Winix Zero 4-Stage is fantastic for allergy/hay fever sufferers, I can breathe so much better with it. It also helps to eliminate pet and food odours in the house. I leave it running all the time and it is very quiet and efficient. If there has been a power outage while I'm not home ( so the air purifier is not running), I'll know as soon as I… Read more

Great unit we just bought a second one – We bought a Winix ZERO 4-stage air purifier two years ago for our bed room and found it has done a fabulous job. We cant believe how much dust it captures from the air. Have just purchased a second one to put in our kitchen and dining area at the other end of the house. Great units and great value for money.

Appears to do what it says on the box – Very quiet especially in auto mode which is ideal for use in a bedroom at night. Very cost effective to run 24/7. Easy to operate. Easy to clean filters. I purchased the product through Ausclimate and would highly recommend their after sales. Russell seemed happy to spend time answering all my questions and concerns - not that I had any particular concerns. A top product I would highly recommended to anyone. Show details
