Austin Air Small Pre-Filter

  • Sale
  • Regular price $23.49

As the first stage of filtration for any Austin Air purifier, the large particle prefilter is a non-woven polyester barrier that traps visible particles like hair and dust while filtering some smaller particles and extending the life of the HEPA filter. This filter can be vacuumed, or blown out periodically to maintain proper air flow and remove debris that this filter attracts and holds.

Genuine Austin Air Permafilt Pre-Filter replaces the pre-filter that comes with Austin Air air purifiers. Long-life pre-filter traps large-sized particles that can easily be seen with the eye during the first stage of Austin Air's multi-stage filtration process. In performing this role, the pre-filter helps to prolong the life of the inner filters, especially the HEPA filter. Pre-Filter lasts for years under normal operating conditions and with regular care. Package contains one (1) Permafilt Pre-Filter. Available in two colors, the white Austin replacement pre-filter goes with White and Sandstone Austin air purifiers units, while the black pre-filter pairs with Black, Silver, and Midnight Blue units. Available in both Standard and Junior sizes, replace annually or as needed depending on unit usage. Always refer to your owners manual for filter changing instructions.
