Austin Air "it" Replacement Filters (FR100 Series)

Genuine Austin Air replacement filters for the compact "it" Personal HEPA Air Purifier. The "it" uses a small filter you can configure to your needs—choose Medical-Grade HEPA on its own, add a VOC Carbon Wrap for odors and light chemicals, or grab the wraps and pre-filter separately. All are genuine Austin Air parts, sized for the "it", and install by hand with no tools.

Choose your configuration

  • HEPA with VOC Carbon Wrap (part FR100C) — Medical-Grade HEPA plus a wrap of activated carbon for odors and light chemical exposure
  • HEPA with Pre-Filter — Medical-Grade HEPA with a large-particle pre-filter for everyday particle filtration
  • VOC Carbon Wrap — the carbon wrap on its own, to refresh odor/chemical control between HEPA changes
  • Large Particle Pre-Filter — the outer pre-filter on its own, to extend the life of your HEPA

Compatibility — does it fit my unit?

  • Fits: Austin Air "it" Personal HEPA Air Purifier
  • Genuine part numbers: FR100 series (the HEPA + VOC Carbon Wrap configuration is FR100C)
  • Not interchangeable with full-size Austin Air filters—the "it" is a compact personal unit with its own filters

When to replace

The Medical-Grade HEPA lasts up to 5 years under normal use. The VOC Carbon Wrap is a wear item—replace it roughly every 3 months for consistent odor and chemical control. The large-particle pre-filter can be replaced as it loads up to protect the HEPA.

Why choose the genuine filter

  • Exact fit for the "it" cabinet, with the proper seal for rated performance
  • Genuine Medical-Grade HEPA and carbon media—not a reduced-media substitute
  • Tool-free installation; configure it to your space

Frequently asked questions

Which configuration should I choose?
For particles only, choose HEPA with Pre-Filter. For odors and light chemicals too, choose HEPA with VOC Carbon Wrap (FR100C). Buy the VOC Wrap or Pre-Filter on their own to refresh those layers between HEPA changes.

How often do I replace the VOC wrap?
About every 3 months; the HEPA lasts up to 5 years.

Is installation hard?
No—the "it" filters install by hand, no tools required.
