Muddada beddelka ah ee lagu taliyey ee filtarrada shidaalka way kala duwan tahay iyadoo ku xidhan qaab-dhismeedkooda, hawl-qabadkooda, iyo isticmaalkooda loogu talogalay, lamana soo koobi karo. Baabuur-sameeyayaasha badankoodu waxay ku talinayaan in la beddelo 48,000 km si loogu dayactiro shaandhada dibadda, iyo 19,200 ilaa 24,000 km si loo dayactiro muxaafid ah. Haddii aadan hubin, kala tasho buug-gacmeedka milkiilaha gaarigaaga si aad u hesho muddada saxda ah ee lagu taliyey ee beddelka.
