Levoit Core 300S vs Dreo Air Purifier 530S
One row in the table below does most of the work here, and it is not a number. The Levoit Core 300S does not use a True HEPA filter; the Dreo 530S does. Levoit's cartridge is a capable high-efficiency filter that performs well in practice, but if you are buying because someone in the house has asthma and a doctor said HEPA, that single distinction is the whole comparison and you can stop reading now.
Everything else is closer than the spec sheet makes it look. Both are small tower units aimed at a bedroom or a home office, both are rated here on the same AHAM basis, and both makers advertise a coverage figure roughly three times larger than the one shown below. Those headline numbers are calculated at one air change per hour, which describes a room the machine can eventually influence rather than one it can actually clean. This table uses the stricter convention, which is why the coverage looks modest here and enormous on the box.
Where the two genuinely diverge is intelligence and honesty, and they trade places. The Dreo has an air-quality sensor and an Auto mode; the Levoit has neither, so it runs at whatever speed you last selected and nothing will change that but you. In exchange, Levoit publishes its power draw and its filter life, and Dreo publishes neither. You can work out what the Core 300S costs to run for a year before you buy it. You cannot do that for the 530S at all.
So the choice is a dumber machine you can budget for against a smarter one you cannot. Neither is the wrong answer. They are wrong for different people, and the score column beside them will not tell you which one you are.
Editor’s note
I would point most people at the Dreo, and I want to be honest about why that recommendation is softer than it sounds. The 530S is the better-specified unit on paper by a clear margin, but Dreo's documentation is genuinely poor: no power draw, no maximum noise figure, no stated filter life. You are buying a machine whose consumable costs you cannot work out until you own it, from a maker still establishing itself in this category.
The Levoit is the opposite kind of product. It is fully documented, cheap to run, and deliberately simple. That simplicity is a real limitation rather than a charming one. With no sensor it cannot respond to cooking, or a candle, or a bad-air day outside. You either run it continuously, which its low draw makes affordable, or you accept that it will be sitting idle at exactly the moments you wanted it working.
The missing True HEPA label on the Levoit will probably get more weight than it deserves. Its filter is a competent high-efficiency cartridge and for household dust and odour it is fine. But it is a label people shop by, and if that is how you shop, the Dreo settles this without any further argument.

Key real-world differences
The spec sheet pulls in both directions. These are the gaps big enough to shape the decision — with the actual figures, and what each one means in real-world use.
- True HEPA filterFiltrationNo vs Yes — only the Dreo Air Purifier 530S has it
A certified HEPA filter captures 99.97% of 0.3-micron particles.
- Air quality sensorSmart featuresNo vs Yes — only the Dreo Air Purifier 530S has it
Measures particle levels to show and react to air quality.
- Auto modeSmart featuresNo vs Yes — only the Dreo Air Purifier 530S has it
Adjusts fan speed automatically based on measured air quality.
- Min noise levelNoise & power22 dB vs 18 dB — 18% less for the Dreo Air Purifier 530S
The lowest-speed noise output; quieter suits bedrooms.
- Coverage areaPerformance219 sq ft vs 201 sq ft — 8% more for the Levoit Core 300S
The room size the purifier is rated to clean effectively.
On paper this is a win, but a gap this small is unlikely to be noticeable in daily use.

What reviewers say
The bottom line
Take the Dreo 530S if the purifier will live in a bedroom and you want it to manage itself. It has the sensor, the Auto mode, the lower noise floor and the True HEPA cartridge, and for most households that combination matters more than knowing the exact annual filter bill.
Take the Levoit Core 300S if you would rather set a speed once, leave it running, and know precisely what that costs. It moves more air, it weighs less, and it is the only one of the two whose running costs you can actually calculate before buying.
The deciding question is not which is better equipped, because that one is settled. It is whether you want a purifier that thinks for you, or one you can account for.
