About LevoitReview.com
LevoitReview.com is an independent product-review site focused entirely on Levoit air purifiers. We started in 2023 after struggling to find honest, technical comparisons of Levoit's expanding Core lineup. Every unit we cover lives in our test space for at least four weeks before we publish.
Editorial independence
We buy every Levoit unit we review at full retail from Amazon, Costco or Vesync's direct store. We do not accept free hardware from Levoit, Vesync or any competitor brand. Our editorial team is based in the United States; we have no corporate or marketing relationship with Vesync.
Affiliate disclosure
When you click an Amazon link on this site and buy something, Amazon pays us a small commission (typically 1-4% of the sale). This is at no extra cost to you. We make money from those commissions regardless of which Levoit (or competitor) you buy - so we have every incentive to be honest about which model actually fits your situation.
Testing methodology
Each Levoit purifier we cover goes through five tests:
- CADR sanity check - we measure smoke CADR using the ANSI/AHAM AC-1 clean-room procedure with KCl aerosol and a Laser Egg 2+ PM2.5 reference sensor. We do not claim our tests are AHAM-certified; we use them to validate manufacturer claims to within 10%.
- Decibel curve - measured at 1 metre using a Reed R8050SD Class 2 sound-level meter, calibrated with a Reed CA-94 acoustic calibrator. Ambient floor measured before each session.
- Power draw - Kill-A-Watt P4400 at each fan speed, integrated over 30 days of continuous run to project annual electricity cost.
- Real-world placement - every unit is rotated through three rooms: a 220 sq ft bedroom, a 380 sq ft living room and a 1,200 sq ft open-plan ground floor. Two weeks per room.
- Filter cost tracking - we log Amazon and Vesync-direct prices for genuine filters quarterly and compare against current third-party generics.
Our writers
The LevoitReview editorial team is anchored by two long-time consumer-tech writers (combined 15 years at outlets like Wirecutter, Engadget and CNET) plus a mechanical engineer who handles the AHAM-style testing. We name individual reviewers in each post byline.
