The short version

Xiaomi wins on performance, smart features, and CADR-per-dollar. Levoit wins on price, simplicity, and voice-control compatibility (Alexa/Google). For most buyers, the Xiaomi Mi Air Purifier 4 Compact ($219) is the best overall value. For budget-focused buyers who want a no-frills purifier, the Levoit Core 300 ($105) is unbeatable.

The head-to-head

1. CADR: Xiaomi wins

ModelCADR (dust)Coverage
Xiaomi 4 Compact~400 mยณ/h~517 sq ft
Xiaomi Smart 4 Compact~360 mยณ/h~517 sq ft
Xiaomi H13~420 mยณ/h~538 sq ft
Levoit Core 300~141 CFM (~220 mยณ/h)~219 sq ft
Levoit Core 300S~141 CFM (~220 mยณ/h)~219 sq ft

The Xiaomi models have 2x the CADR of the Levoit models. This means they clean a room faster and can handle larger spaces. If you have a room over 300 sq ft, the Xiaomi models are the better choice.

2. Noise: Levoit wins (slightly)

ModelLow (dB)High (dB)
Xiaomi 4 Compact2055
Xiaomi Smart 4 Compact2050
Xiaomi H132255
Levoit Core 3002448
Levoit Core 300S2450

The Xiaomi Smart 4 Compact ties the Levoit models at 20 dB (the quietest). The standard Xiaomi 4 Compact is 20 dB on low, which is also excellent. The Levoit models are 24 dB, which is still very quiet but not quite as silent.

For most buyers, the difference between 20 and 24 dB is negligible. Both are quiet enough to run all night.

3. Smart features: Xiaomi wins big

Xiaomi’s Mi Home ecosystem is the standout. It’s the most complete smart-home platform in the world, with 200+ compatible devices. Your air purifier can work with your lights, thermostat, security camera, and smart speaker โ€” all in one app.

Levoit’s advantage: Direct Alexa/Google integration. If you’re in the Google Home or Alexa ecosystem (and not in Mi Home), the Core 300S is the better choice.

4. Filter cost: Levoit wins

ModelFilter costIntervalAnnual cost
Xiaomi 4 Compact~$40โ€“506โ€“12 months$40โ€“100
Xiaomi Smart 4 Compact~$406โ€“12 months$40โ€“80
Xiaomi H13~$456โ€“12 months$45โ€“90
Levoit Core 300~$306โ€“8 months$60โ€“80
Levoit Core 300S~$306โ€“8 months$60โ€“80

The Levoit filters are cheaper per unit, but they need replacing more frequently. Over 3 years, the total filter cost is similar:

  • Xiaomi 4 Compact: $120โ€“300 (3 years)
  • Levoit Core 300: $180โ€“240 (3 years)

The Xiaomi 4 Compact has the best 3-year filter cost if you can stretch the interval to 12 months.

5. Price: Levoit wins

ModelPriceCADR per dollar
Xiaomi 4 Compact$2191.83
Xiaomi Smart 4 Compact$1991.81
Xiaomi H13$2491.69
Levoit Core 300$1052.10
Levoit Core 300S$1501.47

The Levoit Core 300 has the best CADR-per-dollar ratio. You get more clean air per dollar. But the Xiaomi models have more CADR in absolute terms.

The verdict by use case

Best for a bedroom (200โ€“300 sq ft)

Winner: Levoit Core 300 ($105)

You don’t need 400 mยณ/h of CADR for a 200 sq ft bedroom. The Core 300’s 141 CFM is plenty, and it costs half as much as the Xiaomi models. If you want smart features, step up to the Core 300S ($150).

Best for a living room (400โ€“600 sq ft)

Winner: Xiaomi Mi Air Purifier 4 Compact ($219)

A 500 sq ft living room needs at least 330 mยณ/h of CADR. The Levoit models can’t handle this space. The 4 Compact’s 400 mยณ/h is the right size, and the Mi Home app is a bonus.

Best for open-plan spaces (600+ sq ft)

Winner: Xiaomi Air Purifier H13 ($249)

The H13’s 420 mยณ/h is the highest CADR in our comparison. For an open-plan living + dining area, this is the right size.

Best for smart-home integration

Winner: Xiaomi (all models)

If you’re in the Mi Home ecosystem, the Xiaomi models are the clear winner. The Mi Home app is more complete than Levoit’s, and the Xiaomi purifiers integrate with 200+ other devices.

Best for Alexa/Google users

Winner: Levoit Core 300S ($150)

If you’re in the Google Home or Alexa ecosystem (and not in Mi Home), the Core 300S is the only model in our comparison with direct voice-control integration.

Best budget pick

Winner: Levoit Core 300 ($105)

At $105, it’s the cheapest True HEPA purifier you can buy. No smart features, no app, no Wi-Fi โ€” just a purifier that cleans the air. For a small room, it’s the best value.

The bottom line

Xiaomi is the better brand if you want performance, smart features, and a complete ecosystem. The 4 Compact ($219) is the best overall value in the compact/medium size range.

Levoit is the better brand if you want simplicity, affordability, and direct voice control. The Core 300 ($105) is the best budget pick, and the Core 300S ($150) is the best smart pick for Alexa/Google users.

For most buyers: The Xiaomi Mi Air Purifier 4 Compact is the best choice. It has the best CADR, the best smart integration, and a price that makes sense. The only reason to choose Levoit is if you’re on a tight budget or you’re firmly in the Alexa/Google ecosystem.
