iRobot HEPA3 Filter (4639161) Compatibility Finder
iRobot’s Roomba e-Series, i-Series, j7, and the Combo i5/j5 all share the same high-efficiency filter, part number 4639161, sold as a 3-pack. One important exception: this filter does not fit the newer Combo j7+/j9+ models — check the table below before buying.
Which iRobot Models Use the HEPA3 Filter?
| iRobot Model | Filter |
|---|---|
| Roomba e Series, i Series, j7, Combo i5, Combo j5 | 4639161 High-Efficiency Filter, 3-Pack |
This filter is NOT compatible with Combo j7+ or Combo j9+ — those newer self-emptying models use a different filter housing. If your Roomba is a Combo j7+ or j9+, do not buy this filter; check iRobot’s own parts lookup for your specific model instead. (Confirmed against iRobot’s official Combo j7+/j9+ filter page, part 4785883 — Combo j7+/j9+ use that separate part number, not the 4639161 covered here.)
How Often Should You Replace the HEPA3?
Replace every 2 months under typical use — robot vacuums run more frequent, shorter cycles than upright vacuums, so their filters saturate faster on a calendar basis even though total runtime may be similar. If your Roomba’s app shows a “clean filter” or “replace filter” alert, treat that as the more reliable signal over the 2-month estimate.

Frequently Asked Questions
Does the HEPA3 filter fit the Roomba Combo j7+?
No. The Combo j7+ and j9+ use a different filter housing — this filter is confirmed compatible only with the e Series, i Series, j7 (non-plus), Combo i5, and Combo j5.
How often should I replace my Roomba’s filter?
Every 2 months under typical use, or sooner if your Roomba’s app shows a filter-replacement alert.
Is the HEPA3 filter washable?
No — it’s a disposable filter designed for replacement on a fixed schedule, not rinsing and reuse.
