Verdict

The Ufesa PF4500 is a compact 35 W air purifier with a CADR of about 95 m³/h for small to medium rooms. Its three-stage pre-filter, activated-carbon and HEPA system is complemented by an ion function, three fan speeds, touch controls, an up-to-8-hour timer, filter indicator and a quiet night mode around 30 dB(A). It is easy to use in bedrooms and smaller living spaces, but its modest airflow, recurring filter cost and lack of smart app control limit it for large rooms.
