Very good deumerant filter covers 2 slots for ventilos 120mmm. BUT not wide enough and long to 140mm 2 then that is the purpose of my purchase, I am on the rabatre 2 DEMCiflex filters 140mm square that covers them perfectly throughout the area concerned ... so this purchase will do for a double filter 120mm, considering the price I liked to be notified of exact dimensions is: length = 278 Ext / int = 248mm - width = 138 ext / int = 112mm 140mm while a simple fact ext: 152mm / int : 128mm; Find the mistake! SO be careful to cover the dimensions, knowing that the rim is 14 to aimenté 15mmm.
