- Reviewed in the United Kingdom on 12 June 2025This is fantastic! Easy to set up and very easy to understand. My flat mate smokes and it made the air quality go from over 400 to 4, in 5 minutes.
The speed settings are amazing and it’s marked clearly which setting it should be on, depending on the air quality.
Night mode is great, it’s very quiet and genuinely helped me sleep because it’s like a really gentle white noise. The brightness setting on night mode is great, you can barely see the light.
Easy to connect to WiFi and the app is really helpful.
Also has helped with dust and dog hair, my allergies haven’t been playing up anywhere near as much.
Has a lovely cool breeze that helps make the room feel so much fresher and has a good range so can be used on the landing to tackle multiple rooms at once.
- Reviewed in the United Kingdom on 21 June 2025I use this at night in my bedroom, it's pretty quiet in night mode. I find I cough less at night (I have lots of allergies) since having it in there which is good.
- Reviewed in the United Kingdom on 7 July 2025Fantastic,, great price,, excellent delivery on time and a smile 😄
- Reviewed in the United Kingdom on 4 June 2025Great product to introduce into your Smart Home. Works great with Alexa. Filters lasted me approx 3 months (and that was both the air purifier being left on 24 hours a day constantly for 3 months).
Would highly recommend!
- Reviewed in the United Kingdom on 11 May 2025Air quality amazing. So pleased I bought this. I still have to set up the app, I’m waiting for new iPhone, works without app anyway.
My partner is a smoker and it drives me crazy but this eliminates all traces, also takes away doggie stinks ….I love the pure quality of the air.
- Reviewed in the United Kingdom on 29 April 2025I bought this air purifier for myself as I have two dogs. I have to say I was very surprised it actually works. I would highly recommend this if you have pets.
- Reviewed in the United Kingdom on 28 April 2025Very pleased with this item works well easy to setup good price
- Reviewed in the United Kingdom on 6 December 2024Got this for my mother in law ahead of a surgery (her air is a little stale and we wanted to make sure her recovery would be extra comfortable for her). Walking into her house after this machine was on for awhile was completely different. It smelled so clean and fresh - you could really feel the difference. I have my own from a different brand and I also noted that this one is WAY quiter and has a lot of useful settings. It wasn't an issue with us, but keep in mind that you can't put it up against a wall due to some sort of venting on the back (it recommends leaving a gap).

5.0 out of 5 stars Made a huge difference to my sleep, excellent purifier
I’ve been using this for 3 months now in my bedroom, and have it set on a daily timer to turn on 3h before I go to bed and then go to night mode, and stay on until 4am. It’s quiet, low-level white noise which is fine to sleep with. My room gets stuffy the moment the windows are closed, but this machine has removed the smell and makes the air feel so clear! I have been sleeping so much better and no longer wake with stuffy nose and itchy eyes, I can breathe clearly. The app is great for setting the timer and functions and for me it was easy to set and forget. This is my best purchase of the year!

5.0 out of 5 stars Efficace sur les particules, mais l'odeur persiste
J’utilise ce purificateur d’air Morento pour assainir la pièce où se trouvent mes imprimantes résine. Il fait bien son travail sur les particules fines, l’air semble plus propre et moins chargé en poussières.
Par contre, l’odeur de résine reste perceptible, donc ce n’est pas une solution miracle pour éliminer complètement les émanations chimiques. Cela dit, en complément d’une bonne ventilation, il apporte un vrai plus en termes de qualité de l’air.
Bon produit, mais ne remplace pas un bon renouvellement d’air !
- RosannePReviewed in Canada on 7 July 2025
5.0 out of 5 stars Great for smaller spaces
I have been using it in the main floor of my house which is just over 1,000 sq. ft. and it works really well. Changing the filter is very, very easy.
I got it because the family occupying my basement had many different smells coming through the vent system and I wanted to monitor the air quality.
Highly recommended for this sized space. When you blow out a candle, you will see the number go up until it clears the smoke. When this happened, I took it off when I had a candle burning and for awhile after I blew it out.
