Clean Obsessed Hoover Type Y HEPA Vacuum Bags, 9-Pack (WindTunnel / Tempo)

Clean Obsessed's Type Y HEPA bag, part CH309, is built for the Hoover WindTunnel and Hoover Tempo upright lines, sold nine to a box. Retailer listings for this bag are not consistent on the label: most carry it as Type Y and two of them list it as Type Z, so go by the bag your machine currently takes rather than by the label alone.

The HEPA-rated media (H-10) is meant to hold back finer dust and allergens than a standard paper bag before they reach the exhaust, which matters most in a WindTunnel or Tempo running daily in a home with pets or allergies.

• Part: CH309, 9 bags per box
• Fits: Hoover WindTunnel, Hoover Tempo
• Also listed as: Type Y (Type Z by some retailers)
• Filtration: HEPA-rated (H-10)

A HEPA bag that has reached capacity will often show reduced airflow well before it looks full through a clear bin, so a noticeably weaker pickup on a WindTunnel or Tempo is worth checking against the bag before assuming a filter or belt issue. Keep the collar fully seated on every change, since a partial seat lets dust bypass the media entirely.

If your manual calls for Type Z rather than Type Y, compare the collar on the bag you are replacing against this one before ordering rather than assuming the two labels interchange. What the sources confirm is the WindTunnel and Tempo fit and the H-10 rating, and the Type Z label is an addition that two of them make.
