Catalytic filters, UV treatment, Ionization and photo-catalysis are only some of the technologies which can be used to improve air quality and eliminate atmospheric pollutants, fine dust and particulates, chemicals and COVs. While technology can help to eliminate pollutants, we suggest plants and photosynthesis to provide in addition an enriched air, to re-equilibrate the amount of ideal oxygen concentration. Plants like the Epipremnum aureum or Dracena Deremensis help to eliminate Formaldeyde; Guzmania lingulata eliminates COVs; Sanseveria eliminates CO2 and produces O2 during night. BioWalls and Spirulina cultures are efficient solutions for air quality improvement.
Technologies greatly help also for water treatment. The latest generation pools and spas, instead of using aggressive chlorine, use natural salt electrolysis to purify water and to disinfect from bacteria and fungi. They also employ ultraviolet light to dechlorinate water so that the disinfected water is not irritant for skin and mucosa and not aggressive for bath suits. Used in shower heads, red tourmaline ceramics invigorate the bath with a Spa effect, projecting far infrared waves; germanium black ceramics produces negative ions and has a cleaning action on the skin by neutralizing dirt, grease and odors, and greatly reduces the use of soap and shampoo; antibacterial white ceramics prevent the formation of pathogens in stagnant water in the shower. Hydrogenated water, according to several studies, works as an antioxidant, neutralizing free radicals and fighting against degenerative processes, skin ageing, wrinkles and other types of oxidative stresses. Water rich in molecular hydrogen, obtained by electrolysis, is used since more than ten years in Japan for multiple purposes like diabetes reduction, elimination of lactic acid for sportsmen and as antiaging.
 New composite materials with air traps and 3D structures are used to decrease noises; smart textiles insulate from electromagnetic fields; catalytic fabrics and nanotechnologies are used to eliminate odours, while aromas and essential oils diffusers are used to create stimulating and fortifying, or relaxing and soothing environments; essential oils  also offer antibacterial properties which are already greatly used in hospitals, nurseries, veterinary clinics and pet shops.
