Top complaints
Blueair Blue Pure 211i Max
- Short filter life
Wirecutter says filters last 6-9 months instead of the typical year. Blueair lists the Particle & Carbon filter at $69.99 and up to 9 months of life.
Source: Wirecutter, Blueair official product page - Stops working after a few months
Amazon's review summary says reliability is concerning, with multiple customers reporting it stopped working after three months. It has a higher Amazon 1-2 star share (10%) than the Coway and Levoit picks.
- Fabric cover gets shaggy and loses stretch
In Wirecutter's long-term testing the washable fabric prefilter collected hair and dust and lost its elasticity after a few washes, so it needed replacing.

Levoit Core 600S Smart Air Purifier
- Loud or rattling at high speeds
Wirecutter heard a persistent rattle on medium-high and high that repositioning didn't fix. HouseFresh measured 62.3 dBA at top speed and an annoying whir on speed 1.
Source: Wirecutter, HouseFresh review - Filter not HEPA as first advertised
HouseFresh says the filter is HEPA-grade only in sleep mode and that Levoit dropped its HEPA claims in 2023 after a BBB challenge brought by Dyson. Particle filtration is still excellent.
Source: HouseFresh review - Bonded filter and running cost
HouseFresh notes the bonded filter must be replaced whole when the carbon is spent ($59.99, 6-12 months; about $173/year to run). Amazon shoppers are split on whether it's worth the price.
