What we like about LEVOIT LV-H135

  • Equipped with built-in wheels making the large unit very easy to move between rooms
  • Provides quick and highly effective air purification for large spaces, apartments, and studios
  • Noticeably improves allergy symptoms and removes smoke, dust, pet dander, and cooking odors
  • Extremely quiet operation when running on Sleep Mode or lower fan speed settings
  • Intuitive touch control panel with a dimmable or completely turn-offable display light for night use
  • Smart Auto Mode automatically adjusts the fan speed based on real-time air quality sensor readings
  • Features a very simple, tool-free cylindrical filter replacement process

What we don't like about LEVOIT LV-H135

  • The maximum turbo speed setting can be quite loud and noisy for some users
  • Replacement filters carry a relatively high ongoing cost
  • Lacks advanced smart features like Wi-Fi app connectivity or an included remote control
  • The power cord is reported by some users to feel somewhat thin or weak
  • The large physical footprint can feel bulky or like overkill for smaller rooms

Verdict

The LEVOIT LV-H135 is a console air purifier featuring an energy-efficient 40W motor and a 3-stage cylindrical filtration system comprising a nylon pre-filter, a True HEPA filter capturing 99.97% of particles down to 0.3 microns, and a custom activated carbon filter. Designed for large rooms, it covers 463 sq ft (43 m²) every 15 minutes, operating with a maximum noise range of 26 to 54 dB and an on-board infrared particle sensor that provides real-time air quality color rings. Main advantages include its high CADR rating, convenient built-in caster wheels for mobility, an automatic fan-speed mode, and a sleep mode with a completely dimmable display. However, it lacks smart home app connectivity, is somewhat noisy on its highest turbo setting, and carries a high ongoing filter replacement cost.
