Pros and cons

Venta LW25 Comfort Plus

  • No wick at all - over ten years that alone is several hundred dollars of filters not bought
  • Eight watts at full speed; the running cost is close to nothing
  • 24 dBA on speed one is genuinely inaudible in a bedroom
  • Venta publishes the ceiling height behind its coverage claim, which nobody else here does
  • No published output rate anywhere in the manual or on the product page, which leaves the 485 sq ft claim unverifiable
  • $400 is a large amount of money up front for a bedroom-sized appliance
  • The disc stack and basin need a proper clean every couple of weeks, and it is a hands-in-the-water job
  • Venta's own cleaner and hygiene discs are an ongoing recommended cost
  • The Original and Comfort Plus versions carry different coverage claims for the same hardware, which does not inspire confidence in either

Venta LW45 Comfort Plus

  • No wick at all, so years of ownership add up to no filters bought
  • Eight watts at full speed; the running cost is close to nothing
  • Whisper quiet on speed one
  • Venta states the 8-foot ceiling behind its coverage figure, which almost nobody else here does
  • No published output rate, on the product page or in the manual, so the 645 sq ft claim cannot be checked
  • $530 puts it among the most expensive units here, and the payback is measured in years, not seasons
  • The disc stack and basin need hands-in-the-water cleaning every couple of weeks
  • At $530 there is still no app, no timer and no display beyond the humidity dial
  • Thirteen pounds empty and awkward to carry full
