Which model should I get?

Generally, the main difference between air purifiers is the effective range. Other important factors to consider are noise level, unit size, and features like auto mode, sleep mode, and timer. Consider which allergens you would like to target, as well as your room size; our team at would also be happy to provide some recommendations!

My room is bigger than the recommended room size—will the air purifier still be effective?

Yes, if the air purifier is running, it is filtering pollutants from the air. Air change per hour (ACH) is used to measure how many times all the air in a room can be purified (or “changed”) by the air purifier in 1 hour. Generally, ACH is the measure of the efficacy of an air purifier. Five changes per hour is recommended for more intense purification, but this number may be less for larger rooms because it takes more time to filter a bigger space.

What is the benefit of a Wi-Fi-compatible air purifier?
Smart air purifiers are compatible with Wi-Fi and can connect to the free VeSync app. This allows you to adjust the fan speed remotely, check your air quality, set a fan timer or schedule, view filter life, pair your smart appliance with Alexa or Google Home, and more. When you’re out running errands, you can look forward to freshly filtered air when you get home! Non-smart air purifiers cannot connect to the VeSync app and can only be manually operated. Wi-Fi-compatible models include:
  • Core 200S
  • Core 300S
  • Core 400S
  • Core 600S
  • LV-PUR131S
Note: You do not have to use smart air purifiers while connected to the VeSync app. All smart air purifiers can also be manually operated.
