This article has basic misreading errors.

It assumes that everything the Wirecutter says about the IKEA filters and non IKEA filters is a reflection of the difference between HEPA filters and non HEPA filters. But the wirecutter article does not imply that. It mentions the IKEA filter is not a true-HEPA filter and mentions other stuff about the IKEA filter which may or may not have derived from the true-HEPA claim.

However, it’s likely true because the IKEA spokesperson they spoke to confirmed this and said it was a deliberate design decision.

I also want to point out that this article makes a big deal of having found something on the IKEA website about its filtering capacity, but seems to miss the fairly obvious point that in the line it highlights, IKEA never states that it’s filters meet the E12 standard. It only states that it’s tested against that standard.
