Winix 5500-2 vs Winix AM90
Bottom line
In our scoring the Winix 5500-2 scores higher at 5.8/10 versus 4.6/10 for the AM90, both in our Limited band. The gap is value: the two clean air at the same verified CADR, but the AM90 costs nearly double per year in filters ($100 vs $55) and $235 more over five years, which in our view makes it the weaker five-year buy for the same cleaning performance. The AM90's genuine edge is its Wi-Fi connectivity and built-in air-quality sensor, features the 5500-2 does not offer. Both carry the same defeatable ionizer, which floors safety to 0.0/10 in our rubric unless you turn PlasmaWave off.
These two Winix units share the same engine on the data: an identical 246 cfm AHAM-verified CADR, the same 360 sq ft rating, the same True HEPA filter, and the same defeatable PlasmaWave ionizer. The real split is running cost. The 5500-2's filters run about $55 a year (~$435 over five years with the device), while the AM90's run about $100 a year (~$670 over five years). The AM90 adds Wi-Fi and an air-quality sensor the 5500-2 lacks.

- Which Winix is the better value?
- In our scoring the 5500-2, at 5.8/10 against the AM90's 4.6/10. Both deliver the same 246 cfm AHAM-verified CADR and the same 360 sq ft rating, but the 5500-2's filters cost about $55 a year versus $100 for the AM90 - roughly $435 over five years against $670. For the same cleaning power, we rank the cheaper-to-run unit ahead.
- Is the AM90 worth the extra money?
- That depends on whether you want Wi-Fi and the built-in air-quality sensor, which the 5500-2 lacks. On cleaning, the data shows no difference: identical 246 cfm verified CADR and the same 360 sq ft rating. In our view, paying a higher up-front price and double the annual filter cost for connectivity is a hard case to make if air-cleaning is your priority.
- Do both units really cover 360 sq ft?
- Both are rated for 360 sq ft, and that figure is backed by their AHAM-verified CADR (246 cfm pollen, 232 smoke, 243 dust) in our scoring, giving about 4.8 air changes per hour at that size. The room claim holds up against the verified test data for both units, which is why each earns 8.0/10 on practical fit.
