Rank #8 in Best Air Purifier 2026: 10 Ranked on Real Air Changes
Morento HY4866-WF Smart Air Purifier, CADR 300 m3/h, Plus 2 HEPA Filters
Price and rating as shown on Amazon when we collected them. Both change.
The MORENTO comes with a spare-filter offer built in: the listing names one pack plus two HEPA filters, on a machine quoting a CADR of 300 cubic metres per hour with Wi-Fi and Alexa control, four fan speeds, an auto mode, double-side air intake and real-time air quality monitoring, at 50 watts in a 3.61 kilogram body with a 24 decibel noise figure.
The two extra filters are the practical difference, because replacement filters are the running cost that people forget to add to the purchase price. Double-side intake is the airflow approach that lets a compact body move more air. At the time of collection it carried 1,565 ratings at 4.3 stars. Everything here comes from the Amazon listing rather than our own testing.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“It works perfectly and keeps the air clean. Very easy to control with the app. Quiet and effective”
Verified purchase“I’m very happy with this air purifier. Setup was quick, and connecting it to Wi-Fi was simple. The unit feels well built and has a clean, modern design that fits nicely into the room.I suffer from dust allergies, and after using this purifier regularly, I noticed a real improvement. The air feels cleaner, there’s visibly less dust settling around the room, and my allergy symptoms have reduced significantly. It’s made a noticeable difference, especially when running in auto mode.The Wi-Fi control is very convenient, allowing you to adjust settings, monitor air quality, and turn it on or off remotely. Noise levels are excellent — it’s almost silent on lower settings and still very manageable on higher speeds, even at night.Overall, this air purifier does exactly what it’s meant to do. It’s effective, easy to use, and genuinely helpful for anyone dealing with dust or allergy issues. Highly recommended.”
