Quiet and efficient
Brilliant! Cleans the air and on low setting you wouldn't even know it is on. So good we purchased a second one for another room.

Clean air and a nice breeze
I purchased this via Amazon as it was on offer, so significantly cheaper the John Lewis. Honestly, the quality and air purification is incredible. Before this, members of my household were continuously sick. Now, we see very few problems. The dust and fluff it picks up weekly, shocks me. The purifier has 3 settings. Sleep mode, medium and high. We set the purifier to high when away and use sleep mode during the night. The noise is barely noticeable in sleep mode but I still wake up feeling fresher than before. It’s energy efficient too. I never turn it off and I’ve seen near enough no change in my energy bill. This purifier only works across the space of a standard room. You would require around 1 purifier per room to clear the house/apartment. The product is far cheaper than other mainstream purifiers and does a fantastic job. I would say the outer filter needs cleaning fortnightly and the main filter every 6 months. The blue air purifier does warn you that the main filter requires changing by showing a solid red light on the top console.

Great Air Purifier
Seems to be working great, keeps the room cool and smelling fresh. Very easy to use, only two touch sensitive buttons. It’s bigger than I anticipated but feel like that’s good value for the price. I can hear the lowest setting at night but it’s like a low white noise so i don’t mind.

Brilliant!
Call me middle aged but i have quite the collection of air purifiers now. And i have been taken in over the years with smart this and smart that and app functionality and honestly its all useless. However! This is brilliant, its aesthetic and simple and just does its thing. There was an absolute and immediate relief to my hayfever. Just use it properly, close the windows and keep the door closed, designate the room you have it in and you will have an instant “hayfever relief room”

Hundred or Zero
Half and half either loud and works very well, makes the room colder as the fan at the top lets out a lot of cold air. Or put the speed slower and cannot tell it’s on, may still be working but it’s rated to do a room of 16m2 that’s what is stated on the box when you receive and as my room if around 32 hence why I ordered this for it to work it would have to stay on max as the power is around 16w which would be good for a small room kids but struggle in a master bedroom or large room

Good filter, very poor controls.
These do filter the air really well judging by how dirty the filters are when you come to replace them. Only down side, the buttons are shocking and trying to reset after a filter change is very frustrating 🤬

Good product.
Was recommended this air purifier by my son in law . I’m having building work done and this really helps keep my rooms dust free . I ended up buying a second one as it was on offer at the time. On the lowest setting it’s quiet enough to leave running. On the highest setting the noise is noticeable, but handy to use to have the air feel and smell fresh quickly. It’s portable and actually easy enough to move from room to room. I have one in the bedroom and one in the living room. The rest of the house smells quite dusty at the moment with the ongoing renovations , the this air purifier works well enough to keep the rooms it’s in smelling fresh and dust free.

Efficace, silencieux la nuit, je l’adore, sauf pour le bouton du dessus
Le but de cet achat était initialement destiné à purifier l’air de ma chambre l’hiver, lorsqu’il fait très froid et que les fenêtres sont collées, ou à certaines périodes du printemps, lorsqu’il y a trop de pollen dans l’air pour pouvoir aérer. J’ai reçu cet article parfaitement protégé et avec un emballage du fabricant que j’ai trouvé astucieux. Une fois reçu, j’ai immédiatement mis en fonction ce purificateur d’air, afin de vérifier s’il était en état de marche. Mise en marche : Grâce au mode d’emploi redirigé aussi en français, la mise en marche s’est faite facilement. Je suis satisfaite d’avoir pu lire les explications dans ma langue (je suis francophone). En appuyant une fois sur le bouton situé sur le dessus, c’est le mode silencieux pour la nuit ou le repos; en appuyant deux fois, c’est le mode normal; en appuyant trois fois, c’est le mode à toute puissance. Observation de ce processus : Il n’y a pas de bouton qui semble s’enfoncer, donc parfois je frôle le dessus et je parviens facilement à changer de mode, parfois il faut davantage appuyer. Je n’ai pas réussi à comprendre où se situe le « capteur » s’il y en a un. Ce serait le seul point négatif que j’aurais à signaler. Pas de télécommande pour ce premier prix, cela me convient parfaitement pour ma chambre. C’est suffisant pour mon usage. Résultat de la filtration : J’ai laissé fonctionner le purificateur environ 1h ou 2h (durée au hasard), puis je suis retournée dans ma chambre. C’est incroyable la sensation de frais que j’ai ressentie! J’ai senti immédiatement la différence, au point que j’ai décidé de m’en servir encore dès maintenant (pas uniquement pour l’hiver), tant j’ai été contente, ravie et impressionnée du résultat. Usage en mode silencieux : Bien que je sois très sensible au bruit en général, j’ai dormi plusieurs nuits avec le purificateur d’air en action en mode silencieux. Et cela s’est très bien passé, à ma grande surprise. Mon confort respiratoire s’est nettement amélioré grâce à cet appareil. Autres modes : Le mode normal est supportable en journée, mais peut-être pas de nombreuses heures consécutives si la personne reste dans la pièce. Très bonne efficacité rapide. Le mode en toute puissance est très bruyant, donc à utiliser lorsque c’est temporaire. Personnellement, je l’ai utilisé lorsque j’ai changé mes draps pour les laver, tout en ayant aéré avant ou après. Si je l’utilise, je ferme la porte de la chambre. Par contre, bien que je sois ravie de mon achat, j’ai faussement cru qu’il y avait un affichage de la qualité de l’air avec un voyant lumineux. Je me suis mélangée avec les photos que j’ai consultées. Donc il serait souhaitable d’indiquer qu’il n’y a pas de télécommande, ni de connexion avec le téléphone, ni d’affichage de la qualité de l’air. Cet appareil me convient parfaitement, à ceci près que j’aurais peut-être préféré investir dans le modèle juste au-dessus qui a le voyant de la qualité de l’air. Conclusion : Je suis très satisfaite de mon achat, en dépit de la difficulté que j’ai parfois à savoir appuyer correctement sur le dessus (j’y parviens toujours). Selon notre budget, nous investisserons possiblement dans un second modèle de cette marque spécialisée, qui aurait un voyant indiquant la qualité de l’air. Je dois préciser quand même que j’ai choisi cette pour ses « compétences », et ce modèle parmi la gamme selon la superficie de ma chambre et le prix abordable du Vendredi fou. Bref, merci à la marque d’exister au Canada. Soyez bien alertes sur les comparaisons de modèles. Enfin, je dirais que ce modèle serait parfait dans une chambre, que ce soit pour un enfant ou un bébé ou des adultes, ou bien dans une petite pièce destinée au télétravail. Bon magasinage!

DO NOT BUY - NO CUSTOMER SERVICE SUPPORT - STOPPED WORKING AFTER 1 YEAR
I bought this item about a year ago. It stopped working. I contacted the manufacturer who, besides taking 1 month to respond, directed me to the local dealer. The local dealer does not respond... I highly recommend you NOT to purchase this. What type of equipment fails after 1 year? And the customer service is one of the worst I faced to date. My advice is to find another brand/supplier.

Appears only option is a UK plug
Excited when it arrived, but quite disappointed when we opened it. Delivered to Australia with a UK plug and because it is a transformer plug I can't just swap it for an Aust plug. Re-checked the post and found no mention of plug type or an option to change. Prob a bit naive, but expected products sold in Australia to have Australian plugs. Apart from that, the product appears OK but can't used it until I get an adapter, may upgrade another star if it works.

Reliable and effective air purifier for allergies
It has been a great addition to my workspace. I’ve been using it at work, and it has noticeably helped with my allergies by improving the air quality around me. It runs quietly and efficiently, making it easy to keep on throughout the day without being distracting. Overall, it’s been a reliable and effective air purifier that has made a real difference in my comfort.
