Winix Zero N Air Purifier (Allergies, Odours, Dust, with HEPA Filter, Carbon Filter, up to 45 m²)

I decided to upgrade to a larger air purifier, as my smaller one didn’t seem to do much and was overly noisy.This Winix Zero N is a sizeable unit, but the payoff is having a much larger air intake and fan. The larger the fan, the quieter they are in my experience.On sleep mode I cannot hear it, even when positioned 1.8m away from my bed. It also features a particulate sensor (that requires periodic cleaning) to analyse dust in real time. So the unit will increase or decrease it’s suction based on environmental contains of the room.The colour changing light (blue: good, amber: fair and red: poor) indicates the quality of the air. But do not that this light is quite bright. But when set on auto mode, that light will turn off (with the exception of a dim mode led light/s when the room is fairly dark) because it has a ambient light sensor.Performance so far seems excellent. Less allergens in my room means less asthma symptoms. The activated carbon filter (four included - lasts three months each) removes food smells and outdoor odours that creep into my bedroom. So overall my room feels and smells fresh. I would really recommend this air purifier - it’s one of the quietest and best performing one to date.

I’ve trialled two purifiers previously (check my older reviews), both went back for pumping plastic and cardboard smells into the air, or the ‘plasmawave’ [on the Fellowes dx95] actually inducing my asthma (which is the reason I didn’t opt for the larger Winix Zero unit despite thinking the extra oomf would be a better fit for my space). I’m finally happy with this one, with some caveats regarding the night mode (see below).I have allergies to many things, my dog, hay-fever, dust, house mould, and the one that was making me suffer the most recently, tree pollen. I was getting up at 4am with awful itching eyes and sneezing fits lately, but when I began using this it vanished overnight. I went from taking the maximum allowed dose of antihistamines and eye drops to needing none the day after I began using this purifier. This is during coronavirus lockdown when trips outside are once daily so hay-fever exposure is still occurring, but limited. I know this to be the machine working and not the pollen count lowering because opening the window closest to the accursed nearby tree brings on sneezing fits and an itchy throat within seconds.The air doesn’t feel different, it’s not like you’re suddenly walking through a field of clover on a Swiss mountain. Maybe the top speed causes a slight cooling effect and that’s what people are confusing with it feeling crisp and fresh. It definitely clears the allergens out that affect me, that’s indisputable. Today though, for some reason it has stayed on red all day even with all the windows closed (maybe the liberal amounts of bleach I’m spraying around door handles to combat the coronavirus threat).I’ve had it roughly a week so far. I ran a lint roller over the outer cloth cover today after hoovering it yesterday, and it’s surprising how much fluff it accumulates in so short a time.So, the basic design problem with auto night mode:It activates in dim light and reduces noise/power/efficiency considerably. Unfortunately in hot weather you might draw the curtains to keep the room cool thus plunging your purifier into night mode where it barely works. I’m not convinced it’s worth leaving on at all on this setting. Why not have an auto mode that isn’t affected by dim light for dim rooms and/or those like myself who are comfortable with fan (white) noise even with it within arm’s reach of my bed so it can still reach the speeds it needs to clean the air?The workaround is to leave it on a manual setting and block out the lights with something placed over them if they bother you at night, but that obviously costs more to run than an automatic adjustment throughout the night.That’s the only problem so far. It’s not insurmountable so I’m keeping it, and mostly happy but slightly wish I’d bought the larger unit for greater coverage.Also, it’s worth noting that top manual speed seems to be stronger than top auto speed. And regarding the noise it generates, if you like a little white noise for sleeping to, I’ve discovered that the fan on setting 2 does a brilliant imitation of distant rain. It’s brilliantly relaxing.

I kept this product on in the living room continuously - it's where we spend most of our time except for sleeping, and as I use a CPAP machine anyhow which has it's own filters, I thought the bedroom wouldn't be a sensible place for it.The first thing that struck me is that the product is large, you can't easily fit it on the sideboard or behind the sofa or anything like that. it's got to sit on the floor somewhere. Not a problem or a criticism, just a comment as I wasn't quite sure when I ordered it!Assembly was simple and the instructions clear except for one of the tags which was pictogram-only, and I could not figure out what it was meant to say until after I'd already done what it said to do (take the filter out the bag before installation). Everything just clicks together, and no special tools or knowledge is required. Removal for cleaning or replacement is just as simple, and the unit came with 2 spare charcoal filters and one spare cover for the front panel.In auto mode, the unit generally runs quietly to itself in the corner, with occasional periods where the fan ramps up as it detects dirtier air. It's never obnoxiously loud but it's noticeable when it really ramps up. it switches to night mode automatically and turns right down.I live in London within the South Circular area, so expected it to pick up a lot of dust from the air. After a few days of it running, I removed the front filter and scraped my fingers across the surface. It was immediately obvious how much dust had been removed by this filter alone.Overall, I'm impressed. I don't notice any obvious difference when I walk in the room and I don't think I ever expected it to change my life. However, I can clearly see that it is working and removing dust/dirt from the air, so I am happy to keep it running and see if there are longer-term effects.

El aparato tiene un funcionamiento muy sencillo y me gusta que tiene el pre filtro lavable, además permite cambiar el filtro HEPA y el de carbón de manera separada, alargando así la vida útil del filtro HEPA (en cada pack de filtros vienen 4 de carbón y uno HEPA, siendo que el de carbón se posiciona ANTES del HEPA). Para mi esto es importante por que aunque el pack de filtros es un poco más caro que el de otras marcas del mismo rango, hace con que sean necesarios menos cambios a lo largo del año frente a una opción no modular y sin el pre filtro lavable. Por otro lado también quiero destacar que el filtro HEPA que lleva es, según el fabricante, un H13, que filtra 99,97% de las partículas (hay marcas cuyo HEPA es un H11, inferior en poder filtrante).El sensor el muy sensible a partículas en el aire y la verdad es que estamos muy contentos con su resultado, además en elModo nocturno disminuye solo la intensidad de los led, y en muy silencioso. Cuando lo compré parece que Amazon había publicado una oferta que solo estaba vigente en UK y por supuesto no me llegó, pero el vendedor ha sido muy atento y se ha comprometido en hacérmelo llegar, así que un 10 en servicio de atención al cliente.

Mittlerweile hatten wir fünf Lüfter bestellt. Den Großen von Levoit haben wir behalten und eben diesen hier. Das ist ein richtig guter Lufter. Der Levoit war ja nochmal €80,- teurer, aber dieser hier kann absolut mithalten! Ich hoffe nur, dass es auch möglich Filter nachzukaufen!

Super facile à utiliser petite notice facile a comprendre. Et indispensable en ville et pour les terrains allergiques.

Cumple sus funciones, en modo nocturno, no se aprecia que esté encendido. Su funcionamiento es muy bueno, por lo que recomendaría adquirirlo.Le vendría bien, en la parte inferior, unas ruedas para su transporte y movilidad, aunque no llegue a ser un peso exagerado al tener que cambiarlo de ubicación, facilitaría mucho su manejo con unas pequeñas ruedas. Aún así, repetiría, sin lugar a dudas.

Marche bien et reste discret selon le mode choisi. Ne refroidit pas la pièce mais rend l’air mais lourd et humide.
