Hitachi Air Purifier EP-TZ50

Clean indoor air is essential for everyday comfort, especially in homes where dust, allergens, cooking smells, and pet odours can build up quickly. The Hitachi Air Purifier EP-TZ50 is built to deliver fast, effective purification for rooms up to 48 m². With a strong CADR of 402 m³/h, it can move large volumes of air in a short time, helping fill the space with fresher air in as little as 10 minutes under suitable conditions. Real-time PM2.5 detection, a multi-stage filtration system, and quiet operation make it a practical choice for bedrooms, living rooms, and other frequently used areas.

Key Features of the Hitachi Air Purifier EP-TZ50

Fresh air reaches every corner quickly thanks to a high CADR of 402 m³/h, delivering around 6,700 litres of clean air per minute. The unit is designed for spaces up to 48 m² and includes PM2.5 detection so you can monitor air quality as it changes.

The HEPA H13 filter captures 99.97% of ultrafine particles as small as 0.1 μm, including fine dust, pollen, pet hair, and many allergens. Combined with active carbon filtration, it also reduces cooking smells, pet odours, cigarette smoke, and certain VOCs for cleaner, fresher-feeling air.

Independent testing shows the purifier can inhibit more than 99% of common bacteria such as Escherichia coli and Staphylococcus aureus, as well as Candida albicans, supporting a more hygienic environment.

A true 360° air intake draws air from all directions, while 12 adjustable fan speeds and three main modes (Fast, Auto, and Sleep) give you flexible control. Sleep mode operates at a quiet 35 dB(A), making it suitable for overnight use. The digital LED display shows air quality in four levels and makes mode changes simple with a single touch.

Filter maintenance is straightforward — the basket is designed for easy removal and cleaning. For added convenience, the HomeDirect mobile app lets you monitor air quality and adjust settings remotely from your phone.
