The set of intelligent sensors carefully monitors the indoor air quality in real time. Their high accuracy is granted by the laser technology. No maintenance is required. You can always check your home air status in just one glance, thanks to the 4 colors of the Air Quality LED Ring that indicates air quality immediately, while the details of the different polluting agents are visible on the product display or via the hOn App.

The Multi-Sensor System detects:



Particulate (PM) Sensor is useful for a real time monitoring of PM 10 and PM 2.5*, detected once per second. Particulate Matter (PM) are minute particles that could be very harmful for health, penetrating deeply into the human body. They are so small and light that tend to stay longer in the air, affecting the respiratory system and the bloodstream.

*PM 10 have a size up to 10 µm and are capable of penetrating the upper respiratory tract. PM 2.5 have a size up to 2.5 µm and they can reach our lungs, thus penetrating deeper into our body.

Temperature and humidity

CO Sensor and Alert

Useful to get an always-on monitoring of Carbon Monoxide presence. CO may come from combustion processes, like the ones originated from heaters, hobs and cookers. The CO Sensor alerts you through an acoustic signal and via the hOn App, to grant a safer home living.

Gas (VOC)

Gas (VOC)

This sensor detects GAS (Volatile Organic Compounds), that can be originated from detergents, solvents, cosmetic and furniture, once every 20 seconds.

CO Sensor and Alert

Temperature and humidity

Specific sensors help having a continuous monitoring of temperature and relative humidity in your home.


H-TRIFILTER is the exclusive Hoover system of filtration for H-PURIFIER, featured with the combined action of 3 different layers of filtration, with a specific function for each layer, to always grant you protection from all the indoor pollutants up to 0.1 micron.


1. The outer layer

It works as a primary filter, intercepting the largest particles such as human and pet hair and dust.


2. The HEPA (H13) filter

This second layer removes 99.97% of up to 0.3μm size particles: such as pollen, dust mites, spores, bacteria and outdoor pollution, but also captures PM 10 and PM2.5. Furthermore, the Hoover HEPA filter has a unique treatment to inhibit pollens once captured by the filter and make them harmless, allowing allergic subjects to manage the filter in complete safety.


3. The Active Carbon filter

The third layer removes harmful gasses and odors. It is composed by active carbons which, thanks to their porosity, adsorb organic volatile compounds (VOC) odors, fumes, cigarette smoke and NO2. GASSES VOC (Volatile Organic Compound) are volatile chemical compounds (such as formaldehyde), that usually come from detergents, glues, solvents, cosmetic, electronic equipment and even by furniture. They are potentially harmful to our health in case of prolonged exposure. NO2 (Nitrogen Dioxide) is typically originated by traffic pollution.


Thanks to H-PURIFIER’s round shape and its 360° Airflow system, purified air is spread evenly in every direction, first toward the ceiling and then across the room to reach every spot in a fast and efficient way. In just about 10 minutes, it purifies a room of 20m2*.

*Time for one-time cleaning of a 20 m2 room (assuming 2,4 m height) based on product max CADR.
