Replacement Hepa Filters
The HEPA filter is an important component of filtration. If these directions are followed properly, then the fit score of the blower depends solely on the filtration efficiency of the filter.
In my experience, only Broad Air’s OEM replacement filters consistently score above 500 on fit tests. Other manufacturers make replacement filters for the Broad AirPro, and are to be used at your own risk and discretion. Tested fit scores ranges are posted here.
| Item | Where to buy | Fit Score Range | H13 (>99.95%) |
|---|---|---|---|
| BROAD AirPro PM 2.5 HEPA Filter | https://a.co/d/5YPByw0 | 500 - 10,000 | Often |
| H13 HEPA Filter, Suitable for BROAD AirPro | https://a.co/d/fWqDI7R | 100 | No |
| Nispira True HEPA Filter Replacement | AVOID | NA | NA |
