 1 HEPA filters---  A  ----HEPA filters (High Efficiency Particulate Air filter) True HEPA air filter remove 99.97% of particles that have a size of 0.3 µmBut HEPA filters cannot remove smells,harmful gases     

                                       B---HEPA filters + Activated Carbon filters.--- Eliminate toxic gases and bad odors       

                                       C---Pre-filters (Add-on filter for large particles)---- these are  additional filter to collect human hair, petshair, large particles and dust..
