Who it is for
- · Large living rooms and open-plan spaces
- · Anyone sensitive to ozone, or with asthma or allergies
Who should skip it
- · Buyers who want independently verified (AHAM) performance
- · Large rooms - its real coverage is smaller than the box claims
What to know before buying
- · The HE601 uses the HE6FKPET Anti-Allergen HEPA filter with Advanced Odor Lock, which Shark says to replace every 6 to 12 months.
- · Shark does not publish an AHAM CADR rating for this model, so it cannot be directly compared on CADR with units that list one.
- · It uses a six-fan design rather than a single fan and is rated by Shark for spaces up to about 1,200 sq ft at the lower cleaning interval.

FAQ
- What replacement filter does the HE601 use?
- It uses the HE6FKPET combined HEPA and Advanced Odor Lock filter, which Shark recommends replacing every 6 to 12 months depending on use.
- Does the Shark Air Purifier 6 have a CADR rating?
- Shark does not publish an AHAM-verified CADR for the HE601, so coverage is stated as a room-size figure rather than a comparable CADR number.
