Overview
Filtering air through a washable fabric pre-filter and a HEPA activated carbon filter, this tower draws in dust, pollen and pet dander. An app and an auto mode adjust the fan without a manual reset each time.
Compact size, app control and a washable pre-filter make it easy to live with in a bedroom. The limitation is that coverage claims differ across the listing, so room size should be matched to the spec table.
Who it's for
Allergy sufferers, pet owners and smoke-sensitive sleepers in bedrooms or offices can use it. Buyers with large rooms should check coverage before buying.
Pros and cons
- HEPA and carbon filter
- App and auto mode
- Compact tower shape
- Coverage claims conflict
- Replacement filter model not listed
- Needs WiFi for app features
- Air flow rate not listed
Performance notes
Air passes the washable pre-filter first, then the HEPA activated carbon filter, which captures fine particles and odors. Real clearing speed depends on room size and fan setting rather than the headline coverage number.
