3G Filtration Technology for Particles, Gaseous Contaminants

3G Filtration Technology

Awarded Innovation by LIFA Air, Invented Together with the World's leading IAQ Scientists and Professionals.

Groundbreaking solution, now available for everyone

Patented 3G air filtration technology is the cornerstone of Lifa Air's worldwide success. 3G stands for “3-in-1 GREEN filter“. The advantages are high efficiency for removing (1) fine particles, (2) bacteria & virus and (3) harmful gases together with massive dust holding capacity achieved in extremely low pressure drop. Standard 3G-filter removes >99,99 % of PM2.5 and >95 % of gases.

3G filtration systems can effectively collect particles, gaseous contaminants and organic compounds. The collected micro-organisms are destroyed daily by UV-radiation where as active carbon layers absorb gaseous contaminants, thus avoiding the risk of secondary pollution. 3G-filters offer comprehensive protection against Nuclear-, Biological- and Chemical threats.

Pre-filter – Protects the finer filter stages and therefore prolongs the filter change interval
UV-lamp – Frequent radiating of filter surface prevents microbiological growth
Air Ionization – Ionization of particles remarkably enhances the filtering capabilities of 3G-filters
Electret filter layer – High dust holding capacity meets superior filtration efficiency in this special electret filter layer. Continuous Ionization maintains high efficiency levels through the whole life span of the filter
Activated carbon layer – Non-woven layer with a big amount of evenly distributed active carbon protects against harmful gases and VOC's
Ionization After Filter – Optional ionization after the filters improves the circulation of particles in the room
Additional active carbon filter – An optional active carbon filter offers additional protection in demanding cases, such as heavily crowded smoking rooms

High class filtration for all particle sizes

The technology was developed by Lifa Air and the Finnish national technical research center (VTT) over several years, resulting in the discovery of an extremely advanced filtration solution. With unique materials and structure, 3G-filters are capable of filtering an wide range of contaminants. Standard 3G-filters can remove >99,95 % of PM0.3, >99,99 % of PM2.5 and >95% of gases & TVOC. All this comes with a very low pressure drop and energy consumption.

The 3G-filters are designed to be used in harsh, polluted and moist conditions. Official tests conducted by authorities show that no other filter can retain its filtration efficiency and low pressure drop after extreme loading with diesel particles. This guarantees huge energy savings and less frequent filter changes.
