The HL 400 air purifier is a mobile air filter unit. Air is drawn in from the environment and passed through a 7-stage filter system. The design air purifier filters viruses, bacteria, odors, pollen and dust. With the help of the filter system, the room air is filtered and pollutants are incorporated. The standard filter box consists of pre-filter, cold catalyst filter, activated carbon filter, antibacterial filter, main filter H10 (according to EN 1822), sterilizing UV-A light and ionization.

The HL 400 V with virus filter box (including certified H14 filter) additionally reduces the concentration of viruses (such as currently the Corona virus) and bacteria.

Stages of the filter system:

1st stage:

Pre-filter
An aluminum filter is used as a pre-filter. The pre-filter filters coarse dust particles of more than 5 micrometers, such as house dust, dandruff, pollen. The filter can be washed out with water and can therefore be used several times. HEYLO recommends replacing the pre-filter annually.

2nd + 3rd stage:

Cold catalytic decomposition filter
The catalytic decomposition reaction of the cold catalyst does not require UV rays, high temperatures or high pressure. Under normal temperature conditions, the catalytic reaction can remove formaldehyde, benzene, Xylene, TVOC and other harmful gases. The reaction produces water and carbon dioxide. It does not cause secondary pollution. It is a safe and environmentally friendly product on the cutting edge, suitable for a healthy home. During the catalytic reaction, the cold catalyst itself is not directly involved in the reaction. The functionality does not change and is not lost. For this reason, you can assume a service life of about 5 years.

Effective formaldehyde filter
The formaldehyde filter with active carbon cleans the air from unwanted odors, gases and substances. It also cleans the air from harmful formaldehyde in a very short time. The substances are absorbed by the activated carbon and when the filter is saturated, it must be replaced. HEYLO recommends this every 6 months.
In case of Stark odor pollution, such as cigarette smoke, more frequent replacement may also be advisable.

4th + 5th stage:

Antibacterial cotton filter
The antibacterial filter is a precision filter that filters particles with a diameter of 5 micrometers. The special filter material also has an antibacterial agent that can effectively kill 99% of all bacteria.

Highly efficient EPA filter (particulate air filter).
The EPA filter filters airborne germs, smoke and dust particles up to 1μm in size at a rate of 99% or more. Combined with the multifunctional filter, the EPA filter can filter out microscopic particles larger than 20 nanometers in diameter, including bacterial molds, dust, allergens and some viruses. According to the World Health Organization, the Corona virus, avian flu virus, influenza virus and Legionella bacteria are larger than 20 nanometers.

6th stage:

Sterilizing UV light
UV sterilization with 365 nanometer UV wavelength light can kill a variety of airborne bacteria. UV disinfection lamp is usually used for air, surface and water disinfection. It can purify the air, eliminate musty odors as well as produce a limited amount of anions. This makes the air fresh and avoids the spread of viruses in the air or on surfaces.

7.stage:

Ionization
By applying strong electric fields, ionizers can electrically charge individual air particles, increasing the concentration of ions in the room air. The charged particles are more reactive and can thus destroy odor molecules and other pollutants. At the same time, differently charged particles attract each other and form larger clumps that sink to the ground more quickly and are easier to filter out of the air.
