Levoit Core 400S vs Koios EPI810

The Levoit Core 400S got praised by TechGearLab and Wirecutter - two highly trusted sources that perform in-depth hands-on testing. It was awarded the "Best Bang for the Buck: Smart Air Purifier" title from TechGearLab and "Great performance plus voice control" from Wirecutter in their respective Air Purifier roundups.

As for the Koios EPI810 - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.

We couldn't find any sources that tested both of these Air Purifiers, so we only analyzed how they performed in reviews from different sites.

We first examined which sources rated each of these best and found that the Levoit Core 400S got its highest, 9.6, rating from Modern Castle, while the Koios EPI810 earned its best, 5.6, score from breathequality.com.

Lastly, in order to better compare them to their competition, we averaged out their review scores and found that the Levoit Core 400S got received considerably better than the majority of other Air Purifiers - it earned an average of 9.2 out of 10 points, compared to the 7.7 overall rating of other Air Purifiers - while the Koios EPI810 performed worse than most of its competitors, with its average review score of 5.6.

It's worth keeping in mind, however, that a direct Levoit Core 400S vs. Koios EPI810 comparison might not be realistic since they're priced differently and some sources have a tendency to review more expensive products better than cheaper ones.
