Whole-house air purifier repair costs $175 to $795 for most homeowners, with HomeAdvisor putting the average at $461.[2] Angi, HomeAdvisor’s corporate sibling, puts the average at $457 with most homeowners spending $175 to $789.[1] The sibling pages publish near-identical figures that diverge slightly, and both versions are reported here as published; matching figures alone do not establish independent corroboration. A new whole-house air purifier installed runs $400 to $4,000 according to HomeGuide.[3]

Angi and HomeAdvisor are corporate siblings. Their figures here are near-identical but diverge slightly on the average ($457 versus $461) and the typical range ($175 to $789 versus $175 to $795); both versions are reported as published, and matching figures alone do not establish independent corroboration. Neither page states a project-count basis for these figures.
Repair cost by repair type
A filter swap is the cheapest job at $25 to $200, while motor work reaches $790.[1]
| Repair type | Angi (per repair) | HomeAdvisor (per repair) |

| Filter replacement | $25 – $200 | $25 – $200 |
| Electronics / circuit board repair | $123 – $450 | $125 – $450 |

Whole-house air purifier repair cost by repair type, from Angi and HomeAdvisor. The sibling pages label the rows differently: Angi lists “electronics repair” at $123 to $450 where HomeAdvisor lists “circuit board repair” at $125 to $450, and Angi’s motor row covers “repair or replacement” where HomeAdvisor’s covers “replacement”. Each label and figure is reported as published.
Filter costs by type
Filters are the recurring consumable: a flat filter runs $5 to $25 in materials, while pleated or extended filters run $30 to $125.[1]

Labor and related fees
Both Angi and HomeAdvisor put labor at $100 to $250 per hour, with HomeAdvisor noting some professionals charge a flat fee instead and that a routine maintenance call averages $120.[1][2] Angi cautions that in-duct installation locations can add labor time, and that underlying HVAC problems discovered during the visit can add $130 to $2,000 to the bill.[1]
Ongoing maintenance costs
Angi puts filter changes and regular cleanings at $25 to $250 annually.[1] HomeAdvisor recommends replacing the filter every 12 months on average and cleaning the mesh pre-filter every two to four weeks, and puts a home air quality test at $420 on average for homeowners unsure whether the purifier is working.[2]
Repair or replace the purifier
HomeAdvisor’s position is that repair is often more cost-effective than replacement, but that a less expensive unit may be better replaced when problems arise.[2] For context on that decision, HomeGuide puts a new whole-house air purifier installed at $400 to $4,000 with a national average of $1,300, and HEPA filter systems at $1,000 to $4,000 with installation.[3]
DIY or hire a pro
Angi is explicit that repairing a whole-house system is not a DIY option, since these units sit inside the ductwork, and that professional work also keeps manufacturer warranties intact; it considers filter changes and cleaning acceptable DIY.[1] HomeAdvisor likewise limits DIY to simple jobs like a dirty filter.[2] For filter swaps, the Air Filters category at Home Depot carries flat and pleated filters by size and MERV rating (non-affiliate link, provided for convenience).
