Wein Personal Air Supply models

AS180i (battery model, 60hrs continuous use)



'The best thing I have done about my perfume sensitivity ever' – Sue Dengate

UPDATE AFTER 6 MONTHS: 'I bought my Wein Air Supply AS180i about six months ago when I was recovering from extreme perfume and chemical sensitivity that had been triggered by an overdose of perfumey body lotion from the passenger in front of me on a small plane. I love my Wein Air Supply and never leave home without it - it is always in my bag, with my wallet. Looking back, I think I made a mistake the first time I used it by not turning it on until I got into the room with a smell. It takes about a full minute to build up a bubble of purified air so now I usually turn it on before I need it. I would now recommend to others to turn your Wein AS on and get used to it at home for half an hour before your first trial in the real world. I now use mine regularly for Tai Chi classes and in the gym - especially when running on the treadmill, where I used to hate having to stop when someone perfumey hopped on the treadmill next to me. During weightlifting classes I have it on the lanyard around my neck but also tuck it in my croptop during bending exercises. My sensitivity to perfumes seems to have improved and I no longer always need to use it during visits to a shopping mall or supermarket although I always have it handy just in case. I wouldn't go to the cinema without it. I also use it sometimes when visiting restrooms and in some motel rooms while travelling. Most recently I was extremely grateful for it while helping our daughter to move house - when we walked into the house for the first time, we found someone had thoughtfully (!) left it closed up for several days with fragrance diffusers and air freshener, so I wore my Wein non-stop for the first few days' - Sue Dengate.

'I decided to give my new Wein Air Supply AS180i a try at the Dusk shop ("Australia's premium retailer of Candles, Home Decor, Home Fragrance ...") as if it will work there it will work just about anywhere! I switched it on upon entering and within about a minute the smell began to recede. I walked around the store for about 10 minutes and could only smell a faint smell. It is usually overpowering. When I came to 8 vaporisers lined up on the shelf working full-tilt the smell came through strongly so I put the Wein up to my nose and the smell receded completely! I was pretty impressed. So if necessary, I probably could have held the Wein up to my nose for the entire time and not smelt anything. Then just before leaving the store I switched it off to compare the difference. Within about 15 to 30 seconds the smell was appalling again and I quickly left. Great product. Would recommend it to anyone having problems with smells' - Barbara

'I have used my new Wein Air Supply AS180i on a couple of occasions now & find it very effective & am so pleased I bought it. I do, however, find it leaves me with a slight metallic taste in my mouth which is a little annoying but so worth it as it means I can now get out and about without feeling headachy or nauseous etc' - Sharyn

'I've used the Wein AS180i quite successfully in 'smelly' shops that would normally affect me and it's also good in crowds of people where there's lots of perfume odours. I didn't need it on two recent short 3hr flights. I keep it ready in my handbag all the time. There is a discernible slight odour and a sensitive person would be nervous that it would cause a reaction but I don't think it does. As you say, it takes a while to adjust but is better than not wearing it' - Brenda

'I have debilitating reactions to fragrances (breathing difficulties, brain fog, migraines) and I had been looking for something like the Wein for some time. My reactions are quite obvious (I sound like Darth) and I have been lucky to have successive work teams that have stopped wearing perfumes as they are aware of how it affects me. But I work in a large, open-plan office and I have a lot of external meetings...

'The Wein AS180i is not bullet-proof, but I have found it to be a good, non-intrusive first defence. For example, I managed to get through a two-day work induction course in a small room; but then I have had two reactions in the past week to strong fragrance-wearers in the office. I would compare the benefit to wearing a mask – with the key advantage of not having to wear a mask...

'One of the less obvious benefits is it opens a discussion (if people notice it at all). My big boss asked earlier in the week what it was. Today he wrote to all staff to explain what it was and request that everybody take care with what they use. A senior manager responded that it would be doing us all a favour – he reacts to fragrances, but thought he was alone...

'So is the Wein worth it? I don’t want to be without it, so for me it’s a yes...

'P.S. Today I just started really feeling the effects of perfume in the office particularly acutely. I looked down and the Wein had run out of battery. That has happened a few times, which I think speaks to it making a difference' - Mel

UPDATE AFTER 6 MONTHS: 'The Wein was great on an international flight last week and to be honest, I am not sure if I would have attempted the trip without it. On the return trip the woman right behind me sprayed her perfume about 45 minutes before landing, which was not pleasant but I was able to hold the Wein up to my nose and escape without a several-day reaction, which would have been the case otherwise. Thank you again for advertising and selling this product' - Mel

'I already own one Wein Air Supply AS180i and don't leave home without it. To be honest I would not be able to work as I now have an allergic reaction to fragrances. The little machine means that I have a barrier to some of the reactions it gives me a chance to get out of the room as my voice box immediately starts to close and I lose my voice, turn red and start breaking out in a rash. If I turn the machine on before I hop out of the car then I can now walk into shopping centres, still can't go in shops like Dusk or Things or walk down the toiletry isle in the supermarket but it has made so much difference to my life' – Dee

[1536] Wein personal air supply helps with MCS, fibromyalgia, migraines - feedback after 1 year "It’s been a brilliant addition to my life" - Lesley


'Unfortunately the Wein Air Supply AS180i was ineffective against my severe level of fragrance and chemical intolerances. I was so disappointed that it couldn't help me. I found I reacted badly to whatever smell (chemical) was coming out of it. The first time I used it I came down with an unusual headache and weakness and felt so unwell I had to go to bed quite early. I go to a weekly meeting which is full of perfumed people. I tried it there holding up it to my nose but I couldn't sit in the main hall and cope with the perfumes. I started coughing after 5 days and by the 7th day the cough was really constant and I was noticing a strong chemical taste in my mouth and throat. I just couldn't stand the positive ions from the Wein anymore and decided to stop using it. It was worth trying. Maybe something will help me one day' - Suzie

AS300R (USB rechargeable, 30hrs continuous use)



‘I was a little sceptical when I first turned the Wein Personal Air Supply (rechargeable model AS300R) on because the force of air coming from it didn't seem powerful enough to make a difference. But I was surprised. It has helped a lot. When entering areas with strong fragrance I do lift the unit up to my nose to better filter out those fragrances. It seems to work a lot more effectively on natural fragrances from flowers, rather than chemical smells like the cleaning aisle in Coles’ – Jen

‘I'm finding the Wein AS300R very helpful. It has definitely helped lift a lot of my brain fog (I've been diagnosed with MCS which has a huge impact on my diet and food tolerance). I did find the Wein smelly from VOCs (unwearable) when I first received it and put it outside in the fresh air and wrapped in carbon fabric overnight which helped a lot and it's now wearable. I can see how others might struggle. It has also helped in the car. I use an air purifier in the car but I was still struggling. Wearing the Wein as well while in the car, means I arrive at work after my morning commute with a clear head and start my day able to think. At work I have a small office, also with an air purifier in it and I do reasonably well in that room. However, every time I leave that room I'm exposed to building VOCs, cooking smells from a cafe in the building, air "freshener" smells in the toilets, food smells where people prepare lunches and general perfume, laundry powder, deodorant smells - the typical stuff that causes problems for us sensitive folk. Here the Wein really works well. I do notice it struggles with any of these if they are very strong. My husband is thrilled with my improvement so far. Thanks for making this great tool available. I can see I'll be using it a lot and I plan to buy a second one as back up’ - Frances

‘I’ve used the original Wein Air purifier model AS-1500B for many years and it still works perfectly fine. The latest new model AS-300R that I purchased recently is about 1.5 times smaller than the AS-1500B, has rechargeable battery, silent (AS-1500B produced some noise), seems to provide stronger output that I can feel at 18-20 cm (7-8 inches) distance from the nose and looks so cute.

‘Note that Wein Air Purifiers are not negative ion generators. They purify air by destroying pathogens with corona discharge and streaming purified air to the nose. They are supposed to produce some ozone but emission of ozone is minimal. I am sensitive to ozone and I could feel a bit of ozone smell keeping old model close to the nose. However, I can’t smell ozone keeping the new model just next to the nose (I believe the recommended distance from the nose is 15 – 20 cm or 6-8 inches).

‘I purchased AS-300R at Food Intolerance online shop. I had great experience with them: excellent support, quick delivery and competitive price! Thank you for your care and cooperation and for selling it in Australia’ – Boris


‘Unfortunately I have not been able to use the Wein Personal Air Supply AS300R since I am sensitive to using it and it creates symptoms. I am extremely sensitive to everything so it’s not that unusual for me to get symptoms from things that I shouldn’t, however, I wasn't even aware that people could be sensitive to air purifiers. So I guess the only feedback I can offer is, maybe it could be helpful for other super responders/ severe chemical responders like me to have a small disclaimer in the product description outlining the possibility of having reactions to ionic air filters. Just for context. I am not just a little extra sensitive, I have chronic fatigue and MCS and I can’t tolerate anything at ALL. Finding pants is a nightmare. Lol. I can currently only eat 5 foods in the strict column without symptoms and I have to limit them too’ – Amanda

‘The WEIN air supply AS300R arrived today and I tried it at home before going out for about 45 minutes and then also when I went to pick my children up from preschool and school. Unfortunately, I found that it was causing a burning sensation in my nose, as well as an irritated feeling in my airways (even at home where I have no perfumes or chemicals). I would desperately love for this Wein Personal Air Supply to work for me as I have severe perfume and chemical allergies, often leading to anaphylaxis. I have three young children and my perfume allergies are making life extremely challenging at the moment - just recently I had 6 anaphylactic reactions in one month requiring epi pens. I am a long time follower of your website and the failsafe diet has helped me for nearly 20 years now’ - RR

Both the above people tried the battery AS180i version which has a far lower ion output - 1.5 versus 50 million ions/cc - to see if that helps. Feedback:

The battery powered Wein air supply AS180i has been working really well for me and I am not reacting to it like I did the rechargeable AS300R - which is really, really wonderful! - RR

Wein Room Ionic Air Purifier VI3500

download Vortex manual (10 pages)



We have been running our Vortex air purifier ever since it arrived and have been surprised - we thought the air inside our house wasn't too bad, but we can feel the difference and see for ourselves the ash and soot precipitated by the negative ions, as you can see here in a sealed room after one day. Two days later there was no more "soot", showing that the air had been cleared - Sue Dengate


I am impressed with it.  I have it stationed downstairs (approx 15 square metres) and I notice it is working upstairs as well which is approx 15 square metres too.  We had a damp smell downstairs and the vortex complete eliminated that smell.  The amount of stuff I am wiping surround the unit is black!  The recent smoky days we had, it worked so effectively - Teresa
