The set of filters includes a HEPA filter (art. 195277), or a fine filter, sponge motor protection filter (art. 195280), which in the XT series models is mounted on top of the HEPA filter and protects it from moisture. The kit also includes an MCA microfilter (art. 195273) designed to retain dust that flies from the motor brushes.
The manufacturer recommends changing all filters in XT series vacuum cleaners once a year, and the MKA filter once every six months. But the frequency of replacement directly depends on many factors: the degree of contamination, area, operating conditions, etc.
