GermGuardian AC5350 vs Winix AM90

Analysis:

The GermGuardian AC5350 and Winix AM90 make for good, if unremarkable, Air Purifiers at their respective budgets.

With that said, while they both should serve reasonably well, you might want to look into other options at the $140 and $230 price points - it's likely that there are some better alternatives available.

If you want to learn more about the GermGuardian AC5350 and the Winix AM90, however, we prepared a summary of the information that we have:

The reviewers at TechGearLab have featured the GermGuardian AC5350 in their The 5 Best Air Purifiers roundup. However, it fell short of making it to the top of their list.

Taking a look at the Winix AM90, it got featured in roundups from two reliable sources that conduct their own testing - Wirecutter and Popular Mechanics - but it fell short of earning a top spot in either.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like breathequality.com, and learned that they all showed a preference for the Winix AM90.

Then we took a look at the highest review scores that these two Air Purifiers received. We found that the GermGuardian AC5350 managed to earn a rating of 9 from TechGearLab, whereas the Winix AM90 got its highest, 9, score from reviewers at breathequality.com.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Air Purifiers on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Air Purifiers being 7.7 out of 10, whereas the GermGuardian AC5350 and Winix AM90 managed averages of 7.8 and 9.0 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct GermGuardian AC5350 vs. Winix AM90 comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
