AllerAir 4000 Replacement Filters

AllerAir logo

Most AllerAir 4000 air purifiers are sold as both regular models (sometimes referred to as Exec models) and Vocarb models, depending on the type of activated carbon they contain. Simply choose the appropriate carbon filter (i.e., Exec or Vocarb) in the dropdown menu for your unit, or contact us if you are unsure. The letters UV merely indicate that your air purifier is equipped with an optional ultraviolet lamp and does not affect the replacement filters required.

Recommended AllerAir 4000 Filter Replacement Schedule


  • HEPA or Super-HEPA filter - every 3 to 5 years
  • Carbon filter - every 2 to 3 years
  • Pre-filter - vacuumed occasionally or changed every 3 to 4 months
  • Optional UV bulb - every year
