Diode sources of UV radiation are used for air purification, which makes the filter compact and increases the service life from 10,000 to 30,000 hours.
For the hydrofilter, a new method of saturating water with oxygen was used, which does not require the use and renewal of reagent fillings.
For the biological method of purification from PCBs, vegetable raw materials were used, which do not give repeated toxic compounds.
