Levoit Sprout Air Purifier

Manufacturer: Levoit

The Levoit Sprout is a mid-sized air purifier built around multi-stage filtration and smart home connectivity. Designed to cover rooms of up to 59 m², it manages air quality automatically through onboard sensors while remaining compatible with Alexa, Google Assistant, and Apple HomeKit. At 2,900 g and running on just 18 W, it is light enough to reposition without hassle and unobtrusive in terms of energy draw. A dedicated smartphone app rounds out the control options, giving users a direct way to monitor the unit remotely, and auto mode adjusts fan speed in response to live air quality readings without requiring manual input.

Filtration runs through three stages — a pre-filter, a HEPA layer, and an active carbon stage — with the HEPA element achieving 99.97% efficiency at 0.3 microns and 99.9% at 0.1 microns. CADR figures are 152.9 m³/hr for dust, 185.2 m³/hr for pollen, and 144.5 m³/hr for smoke. The built-in sensors track PM1, PM2.5, and PM10 particle concentrations, and both an air quality indicator and a filter replacement indicator are included to keep maintenance straightforward. Audible noise spans 19 dB at the lowest fan setting up to 47 dB at maximum speed.

Pros
  • Covers rooms up to 59 m², making it suitable for larger living spaces
  • Three-stage filtration combining HEPA, pre-filter, and active carbon captures particles down to 0.1 microns at 99.9% efficiency
  • Compatible with Alexa, Google Assistant, and Apple HomeKit, offering broad smart home integration
  • Auto mode adjusts fan speed in response to live PM1, PM2.5, and PM10 sensor readings without manual intervention
  • Filter life tracking and a filter replacement indicator take the guesswork out of maintenance
  • Minimum noise level of 19 dB at low speed makes it unobtrusive in quiet environments
Cons
  • Pre-filter is not washable, meaning it must be replaced rather than simply rinsed and reused
  • Does not carry an Energy Star certification
  • Scheduling functionality is not available, limiting automated time-based control
  • Smart location-based on/off control is not supported
  • Maximum noise level of 47 dB at full speed may be noticeable in quiet rooms
Who is this for?

This air purifier is a solid fit for users who want whole-room air quality management in spaces up to 59 m², such as open-plan living areas, home offices, or large bedrooms. Those already embedded in a smart home ecosystem will find the compatibility with Alexa, Google Assistant, and Apple HomeKit genuinely useful, as it allows voice control and app-based monitoring without added friction. The built-in PM1, PM2.5, and PM10 sensors paired with auto mode also make it well-suited to users who prefer a set-and-forget approach rather than manually adjusting settings throughout the day.

Who is this NOT for?

Users who rely heavily on automated scheduling to manage their devices on a fixed daily routine will find this unit limiting, as that functionality is absent. It is also a less natural fit for those seeking energy-efficient, certified hardware, since the unit does not carry an Energy Star label. Additionally, people who prefer low-maintenance filtration — such as washable pre-filters — will need to account for recurring filter replacements, as none of the filter stages can be rinsed and reused.

Filtration is handled through a three-stage system combining a pre-filter, a HEPA layer, and an active carbon stage, achieving 99.97% efficiency at 0.3 microns and 99.9% at 0.1 microns. CADR ratings come in at 152.9 m³/hr for dust, 185.2 m³/hr for pollen, and 144.5 m³/hr for smoke, with an air change coverage of 58 m². A filter replacement indicator is included to signal when maintenance is due, though the pre-filter is not washable and will need to be replaced rather than rinsed.

The unit connects over Wi-Fi and works with Alexa, Google Assistant, and Apple HomeKit, and a dedicated smartphone app provides an additional control layer for remote management. Onboard sensors track PM1, PM2.5, and PM10 particle levels, feeding into an air quality indicator that reflects real-time conditions, while auto mode adjusts fan speed automatically based on those readings. Filter life tracking is also built in, helping users stay on top of maintenance without guesswork. Scheduling and smart location-based on/off control are not supported.

Final Verdict

The Levoit Sprout brings together meaningful filtration performance and broad smart home compatibility in a package suited to larger rooms up to 59 m². Its three-stage filtration system — anchored by a HEPA layer reaching 99.97% efficiency at 0.3 microns — combined with real-time particle sensing and auto mode, makes it a capable everyday air purifier for users who value automation and ecosystem integration across Alexa, Google Assistant, and Apple HomeKit. The absence of scheduling and the non-washable pre-filter do introduce some practical trade-offs, but for users prioritising responsive air quality control in a well-connected home environment, the Sprout represents a well-rounded and technically grounded option within its category.
