Levoit Eleva 300X

AHAM Verifide CADR of 161 CFM (274 m3/h) for smoke, dust and pollen, per the Levoit product page.

Levoit rates the ideal room size at 250 sq ft with 4.8 air changes per hour, which is one full clean every 12.5 minutes. The larger 1200 sq ft figure quoted on the box is measured at a single air change per hour.

Levoit rates the purifier at 20 to 50 dB, with Sleep Mode at the quiet end of that range.

Auto Mode reads the AirSight Plus 2.0 sensor and steps the fan from speed 1 to speed 4 as the air quality worsens. The VeSync app adds a Quiet Auto Mode that caps the fan at speed 2.

Sleep Mode runs the fan below the lowest speed, at around 20 dB, and turns the display off after 3 seconds.

Timers and schedules are set in the VeSync app.

Display Lock, set by holding the Display Off button for 3 seconds, stops the panel responding to taps.

No physical remote is included; control is by the top panel, the VeSync app or a voice assistant.

The VeSync app creates and customises schedules, and Auto Mode reacts to the sensor on its own.

The VeSync app keeps 4 weeks of air quality history, adds weekly and monthly reports, overnight air quality trends and an event history, and tracks remaining life for both filters.

Levoit publishes an AHAM Verifide CADR of 161 CFM, and the Amazon listing states the purifier is third-party certified by AHAM and recognised by ECARF.

LAP-C341S-WUSZ is listed in the ENERGY STAR certified room air cleaners database under the v3.0 specification.

Purely mechanical 3-stage filtration (pre-filter, HEPA and activated carbon) with no ionizer or UV-C stage, and ENERGY STAR v3.0 certification, which requires compliance with the CARB ozone limit.

The FCC grant for this model (FCC ID 2AB22-LAPC341S) authorises 2412-2462 MHz, the 2.4 GHz band.

The FCC grant authorises no 5 GHz band, only 2.4 GHz.

The FCC grant lists a second radio at 2402-2480 MHz and 0.0066 W alongside the Wi-Fi range, the low-power Bluetooth band VeSync uses to pair the purifier with the app.

A digital display on the top panel shows the current AQI and cycles through the PM1.0, PM2.5 and PM10 readings, and can be switched off entirely.

An Air Quality Indicator Ring around the control panel changes colour with the reading: blue for very good, green for good, orange for moderate and red for bad.

Fully sealed system-level HEPA filtration that traps at least 99.97% of airborne particles 0.3 microns in size, per the user manual and the Levoit product page.

A High-Efficiency Activated Carbon Filter ships pre-installed and is replaced independently of the HEPA filter under what Levoit calls DuoShield. Four carbon variants are sold: Essential, Premium, Pet, and Smoke & Cooking.

The pre-filter is bonded to the HEPA filter and is cleaned with a soft brush or vacuum hose every 2 to 4 weeks. The user manual states it must not be cleaned with water or other liquids.

Levoit rates the Pre-Filter / HEPA filter for 18 to 24 months and the activated carbon filter for 6 to 12 months depending on which carbon variant is fitted.

The Amazon listing states you can connect to Alexa and Google Assistant from the VeSync app, and lists Google Assistant under Controller Type.

Levoit documents only Alexa and Google Assistant, and neither Levoit nor Vesync appears in the CSA certified-product database, so there is no Matter path into Apple Home either. Levoit purifiers reach Apple Home only through third-party bridges such as Homebridge, which do not count as support.

No SmartThings integration is documented by Levoit or Samsung, and the automatic Works with SmartThings grant does not apply because the model is not Matter certified.

Home Assistant reaches Levoit purifiers through the VeSync integration, whose device support comes from pyvesync. Its device map matches exact model strings and does not yet list LAP-C341S, so this model is not exposed today. That is an absence of evidence rather than evidence of absence, and it should be re-checked once pyvesync adds the model.

Neither Levoit nor Vesync (US) Corporation appears in the CSA certified-product directory, and no Levoit source claims Matter.
