2026 verdict
If you value sensing and running cost over raw airflow, the Levoit Eleva 300X wins this pairing of Wi-Fi air purifiers.
Its three-channel AirSight sensor reads PM1.0, PM2.5 and PM10 separately, its HEPA and carbon filters are replaced on their own schedules under Levoit's DuoShield design, and it draws just 25 W at full speed. The Winix 5520 is the stronger filter of the two on paper, with a 253 CFM AHAM Verifide CADR for rooms around 392 sq ft, a washable pre-filter and a True HEPA layer that moves far more air than the Levoit's 161 CFM. Neither supports Apple Home, SmartThings or Matter, and both stay on 2.4 GHz Wi-Fi. Pick the Levoit Eleva 300X for a bedroom where quiet running, detailed sensing and low power matter, and the Winix 5520 for a larger room that needs the extra airflow.

What the differences mean
Airflow and room size
The Winix 5520 moves 253 CFM and is AHAM Verifide for rooms around 392 sq ft. The Levoit Eleva 300X moves 161 CFM for about 250 sq ft, so it is a one-room purifier while the Winix is built for a living room or a large bedroom.
Sensing
The Levoit Eleva 300X uses a three-channel laser sensor that reports PM1.0, PM2.5 and PM10 separately and shows them on a display. The Winix 5520 senses PM2.5 only and shows it as a colour light, with the detail left to the app.
Filter design
The Levoit Eleva 300X splits the HEPA and carbon filters so they are replaced on separate schedules, and its pre-filter is bonded rather than washable. The Winix 5520 uses a single stack with a washable pre-filter, so it is rinsed rather than replaced.
Power draw
At full speed the Levoit Eleva 300X draws 25 W and the Winix 5520 draws 50 W. Both are meant to run for long hours, so the difference shows on the electricity bill over a year.
Smart home support
Both work with Alexa and Google Home, and the Winix 5520 adds a community Home Assistant integration. The Levoit Eleva 300X pairs over Bluetooth and its Home Assistant support is not confirmed yet, and neither supports Apple Home or Matter.

Frequently Asked Questions
Which is better overall: Levoit Eleva 300X or Winix 5520?
For a bedroom, the Levoit Eleva 300X, with its three-channel sensor, lower power draw and lower price. The Winix 5520 is the better machine for a larger room, where its 253 CFM AHAM Verifide airflow and washable pre-filter matter more.
What is the biggest difference between the Levoit Eleva 300X and the Winix 5520?
Airflow and sensing. The Winix 5520 moves 253 CFM for rooms around 392 sq ft, while the Levoit Eleva 300X moves 161 CFM for about 250 sq ft but reads PM1.0, PM2.5 and PM10 separately.
Which one is quieter?
The Levoit Eleva 300X is rated from 20 to 50 dB with a sleep mode below its lowest speed. The Winix 5520 does not publish a noise figure, so the Levoit is the safer bedroom choice.
Do either work with Apple Home or Matter?
No. The Levoit Eleva 300X and the Winix 5520 both work with Alexa and Google Home over 2.4 GHz Wi-Fi, but neither supports Apple Home, SmartThings or Matter.
Do these have a washable pre-filter?
The Winix 5520 does, which is why it is rinsed rather than replaced. The Levoit Eleva 300X bonds its pre-filter to the HEPA element, so it is cleaned with a brush or vacuum and never with water.
Who should buy the Winix 5520?
Anyone cleaning a larger living room or open kitchen who wants verified airflow and a washable pre-filter, and does not need the finer particle detail of the Levoit Eleva 300X.
