$219.99
Buy on Amazon USA
For the size of room most people actually have, the Levoit Core 400S-P is the smarter buy and the lower priced of the pair, since both carry the same H13 True HEPA and activated carbon filter, the same PM2.5 auto mode, the same Energy Star and ozone-free certifications and the same Alexa, Google Home and Home Assistant support. The Levoit Core 600S-P earns its higher price only through scale: 391 CFM and a 606 sq ft AHAM rating against 231 CFM and 358 sq ft, with a remote on top. Pick the Levoit Core 400S-P for a normal living room or a large bedroom, and the Levoit Core 600S-P only when the room is genuinely open plan.

What the differences mean

Room size

This is the real fork. The Levoit Core 600S-P is AHAM rated for 606 sq ft at 391 CFM, sized for an open living area or a basement, while the Levoit Core 400S-P covers 358 sq ft at 231 CFM, which is a normal living room or a large bedroom. Put the smaller one in a big space and it runs near its top speed to keep up.

Size and weight

The Levoit Core 400S-P stands 520 mm tall and weighs 11 lb, so it moves between rooms without effort. The Levoit Core 600S-P is taller and heavier at 599 mm and 13.7 lb, a cabinet that tends to stay where it is placed.

Remote control

The Levoit Core 600S-P ships with a physical remote, which matters if the purifier sits across the room and you would rather not reach for a phone. The Levoit Core 400S-P has no remote and is controlled from its panel or the VeSync app.

Power at full speed

The Levoit Core 400S-P draws 38 W at its top speed and the Levoit Core 600S-P 66 W. Both are Energy Star certified, so neither is costly to leave on, but the larger fan is the one that shows on the bill over a year.

Noise at the top speed

Rated 52 dB for the Levoit Core 400S-P and 55 dB for the Levoit Core 600S-P, the gap is small; both are quiet at their lowest settings and both are clearly audible at full blast.

Which one to buy if

What owners say

Owners of both Levoit Core models tell the same story about the app and the sensor: auto mode spins up the moment a pan starts smoking and settles back down, sleep mode is quiet enough to forget, and the VeSync app handles schedules and filter life without fuss. Where they part is scale and upkeep. Levoit Core 400S-P owners describe a living-room purifier they can move around, but warn that the top speed is audible and the sealed cartridge cannot be washed, so the whole filter is replaced roughly every eight months. Levoit Core 600S-P owners talk about a machine that clears smoke, cooking and pet odours from a large open space, and they single out the remote and the stronger airflow, with the same filter cost and the same top-speed noise as the trade-off.

Upgrading from the Levoit Core 400S-P?

Moving from the Levoit Core 400S-P to the Levoit Core 600S-P buys airflow and very little else. The H13 True HEPA and carbon filter, the PM2.5 sensor and its auto mode, the VeSync app and the smart home support are identical, so a Core 400S-P that already keeps its room clean has nothing to gain. The step up is worth it only when the purifier has moved into a space past roughly 400 sq ft, or when it now runs at its top speed most of the day. If that is not your situation, the Levoit Core 400S-P remains the better value.

Frequently Asked Questions

Which is better overall: Levoit Core 400S-P or Levoit Core 600S-P?

For a normal room, the Levoit Core 400S-P. It carries the same H13 filter, PM2.5 auto mode and smart home support as the Levoit Core 600S-P for less, and its 358 sq ft rating fits a living room or a large bedroom. The Levoit Core 600S-P is the pick only when the space is genuinely large.

What is the difference between the Levoit Core 400S-P and the Levoit Core 600S-P?

Room size and airflow. The Levoit Core 600S-P is AHAM rated for 606 sq ft at 391 CFM, while the Levoit Core 400S-P covers 358 sq ft at 231 CFM. The bigger model also adds a remote and draws more power at full speed.

Do the Levoit Core 400S-P and the Levoit Core 600S-P use the same filter?

They use the same design: an H13 True HEPA layer with activated carbon, rated for about eight months. Neither has a separate washable pre-filter, so the full cartridge is replaced at that interval.

Do the Levoit Core 400S-P and the Levoit Core 600S-P work with Apple Home or Matter?

Neither does. Both work with Alexa, Google Home and Home Assistant through the VeSync app, and neither supports Apple Home, SmartThings or Matter. Both use 2.4 GHz Wi-Fi only.

Which is quieter, the Levoit Core 400S-P or the Levoit Core 600S-P?

They are close. Levoit rates the Levoit Core 400S-P at 52 dB and the Levoit Core 600S-P at 55 dB at their top speeds, and both drop to a quiet low setting. Neither top speed is meant for sleeping.

Who should buy the Levoit Core 600S-P?

Anyone cleaning an open living area, a basement or a large bedroom where a 231 CFM purifier would have to run flat out, and buyers who want the remote that the smaller model lacks.
