Madzix4 years ago000Hi, does the Miele Triflex HX1 has HEPA filter (do we need to replace it after some time?) or Maintenance-free Hygiene Lifetime Filter?siddharathgupta4 years ago000I think miele says lifelong. I have been using it the vacuum for sometime and do think its wise to change the filter once a while 1 yr or so. You van tap the filter clean but still some dust staysComment
