Levoit Core 300S vs Core 300P

The Levoit Core 300S-P is the better pick for most bedrooms and home offices: it is quieter at every fan speed, uses less than half the power, and adds app control plus a real-time air quality sensor that the plain Core 300-P does not have. The Core 300-P costs $50 less to buy, but its higher rated power means it can end up costing more to run over three years than the smart model it is meant to undercut.

Both units share the same 3-stage filter, the same CADR rating within 2 CFM of each other, and the same 2-year limited warranty from Levoit’s parent company, VeSync. The real differences are noise, power draw, and whether you want the purifier on your phone or just on your nightstand.

Core 300-P vs Core 300S-P: the numbers

Where the Core 300S-P wins

The Core 300S-P is quieter at both ends of its range: 22 dB on low against 24 dB on the Core 300-P, and 50 dB on high against 54.5 dB. That 4.5 dB gap on top speed is the difference between a purifier you can sleep next to on boost mode and one you cannot.

It also runs on a 23W rated power draw, less than half the Core 300-P’s 56W, and it is the only one of the two with Levoit’s AirSight Plus sensor, which reads the room and shows a live air quality color indicator on the control panel. Pair that with VeSync app scheduling and Alexa or Google Assistant voice control, and the 300S-P is the one built to run unattended on a schedule.

Where the Core 300-P wins

The Core 300-P is $50 cheaper to buy and needs no app, no WiFi network and no account to run. Press a button and it works. For a closet, a small home office, or anyone who wants a purifier that never needs a firmware update, that simplicity is worth something the spec sheet does not capture.

Its CADR of 143 CFM is technically the higher number of the two, though the 2 CFM gap against the 300S-P’s 141 CFM is inside rounding error and not something you would notice in a real room. Treat CADR as a tie.

The 3-year cost, including power

Both purifiers use the identical Levoit Core 300 Series filter at $29.99 a filter, and Levoit’s own guidance is to replace it every 6 to 8 months, so the filter cost is the same on both: about $179.94 over three years at two filters a year. The gap shows up in electricity. Assuming 24 hours a day of runtime at $0.17 per kWh, the Core 300-P’s 56W draw adds about $250 in power over three years, against about $103 for the 300S-P’s 23W draw. Add it up and the cheaper-looking Core 300-P totals close to $530 over three years, while the pricier Core 300S-P lands near $433. The $50 you save on day one can turn into a $97 loss by year three if you run the purifier around the clock. Run it fewer hours a day and that gap narrows, but it does not flip in the Core 300-P’s favor at any normal usage pattern, since its rated power is still more than double.

Choose the Core 300-P if

• You want the lowest purchase price and do not care about app control.
• You do not want another device on your home WiFi network.
• The purifier will run only part of the day, where the power gap matters less.

Choose the Core 300S-P if

• You want to see live air quality readings and schedule the purifier from your phone.
• You are running it in a bedroom and want the quietest setting available.
• You plan to run it most of the day, where the lower power draw pays back the $50 price gap.

FAQ

Is the Levoit Core 300S-P worth $50 more than the Core 300-P?

If you want app control, voice control, or a live air quality reading, yes. If you just want a purifier that runs at the push of a button, the Core 300-P covers nearly the same room size for less money up front.

Do the Core 300-P and Core 300S-P use the same filter?

Yes. Both use the Levoit Core 300 Series Original Filter, listed at $29.99 on Levoit’s site, with the same replacement window of every 6 to 8 months.

Which one is quieter?

The Core 300S-P, at 22 to 50 dB against the Core 300-P’s 24 to 54.5 dB across the same speed range.

Does the Core 300-P have an app?

No. It has touch button controls for fan speed, sleep mode and a 2 to 8 hour timer, with no WiFi or app connectivity. The Core 300S-P is the smart model in this pair.
