Head-to-head

Levoit Core 300-P vs Levoit Core 300S-P: 300S changes the fan automatically, 300 keeps manual control

The short answer

Choose the Core 300S-P for automatic fan changes, schedules and lower rated power. The Core 300-P suits people who only want local controls.

Before you choose

The reasoning and the trade-offs

Compare room size at the same turnover

At five air changes per hour and an eight-foot ceiling, Levoit Core 300-P calculates to about 215 square feet and Levoit Core 300S-P to 212.

What this is based on

Area = CADR × 60 / (ceiling feet × air changes per hour). Inputs are 143 and 141 CFM, 8 feet and 5 changes. Generic published CADR is used at maximum speed. Air mixing, furniture, open doors and filter loading affect real conditions.

Main trade-off

Levoit Core 300-P

It has no air-quality sensor, Auto mode or Wi-Fi.

Main trade-off

Levoit Core 300S-P

RTINGS does not classify the current filter as formally HEPA-certified.

About this comparison

Choose the Core 300S-P for automatic fan changes, schedules and lower rated power. The Core 300-P suits people who only want local controls.

The smart model is not a room-size upgrade

Winner by situation

Start with what you need it to do

  • The room is large enough to need extra airflow

    The same five-change, eight-foot-ceiling calculation gives about 215 and 212 square feet. That tiny difference is not a useful reason to choose one. App control and automatic sensing are more relevant distinctions.

  • The cabinet has to fit beside furniture

    Allow 8.7 inches of width and 8.7 inches of depth for Levoit Core 300-P, or 8.7 by 8.7 for Levoit Core 300S-P. Intake clearance is extra, so measure the gap in both directions.

  • I want control from another room

    Levoit Core 300S-P has app control. Levoit Core 300-P uses local controls, which suits a fixed routine but cannot meet a remote-control requirement.

  • The ceiling is ten feet high

    At ten feet and five air changes, the modeled room areas fall to 172 square feet for Levoit Core 300-P and 169 for Levoit Core 300S-P. That is 20% less floor area than the eight-foot example because the purifier has more air to move.

What matters in practice

The differences that matter

Compare room size at the same turnover

At five air changes per hour and an eight-foot ceiling, Levoit Core 300-P calculates to about 215 square feet and Levoit Core 300S-P to 212.

How we reached this conclusion

Area = CADR × 60 / (ceiling feet × air changes per hour). Inputs are 143 and 141 CFM, 8 feet and 5 changes. Generic published CADR is used at maximum speed. Air mixing, furniture, open doors and filter loading affect real conditions.

Measure the cabinet before buying

Levoit Core 300-P occupies a 75.7-square-inch cabinet envelope versus 75.7 for Levoit Core 300S-P. A shallower shape can still need more wall width.

How we reached this conclusion

Width × depth: 8.7 × 8.7 = 75.7 in² and 8.7 × 8.7 = 75.7 in². These are cabinet bounding rectangles, excluding required air clearance.

Same space, substantially lower rated input

The Core 300S-P cuts rated input by about 59% while keeping the same cabinet footprint as the Core 300-P.

How we reached this conclusion

(56 - 23) / 56 × 100 = 58.9%. Both are 8.7 × 8.7 inches. This compares nameplate power, not measured power at equal sound or airflow.

Try your real numbers

Will either purifier move enough clean air?

The result checks hard limits only. Preferences stay out of the calculation.

Levoit Core 300-P

Does not fit these inputs

143 CFM of verified clean-air delivery gives about 3.6 air changes per hour here. The 5 ACH target needs 200 CFM. Use the original filter at maximum speed. Sleep and other replacement filters are not rated here.

Levoit Core 300S-P

Needs a manual check

No comparable verified smoke CADR is stored for this exact model.

This uses maximum-speed, pollutant-specific CADR and a five-air-changes-per-hour target. Quieter settings deliver less clean air. It does not substitute raw airflow or a one-change coverage claim.

Choice A

What you give up

Every choice has a cost

If you choose Levoit Core 300-P

  • The internal prefilter is vacuum-cleaned rather than removable and washable.

If you choose Levoit Core 300S-P

  • Airflow at its quietest settings is limited, so a smoky room needs a higher and more audible speed.

What matters in practice

How to make the call

01

The smart model is not a room-size upgrade

Levoit lists 143 generic CADR for the 300-P and 141 for the 300S-P. Their stated 4.8-change room sizes are 222 and 219 square feet, so automation is the practical reason to choose S.

02

Schedules and Auto mode solve separate problems

Schedules turn the purifier on around your routine. The particle sensor changes airflow when room conditions change. The plain Core 300 has neither function.

03

Rated power can affect an all-day choice

The two models use the same 8.7-inch square placement envelope, while rated power falls from 56 to 23 watts. At full rated input for 24 hours, the difference is 0.792 kWh per day.

Check these before buying

  • Measure the room and ceiling before choosing the target airflow.
  • Check the exact US model, complete replacement-filter set and seller on Amazon.

What this comparison cannot tell you

  • CADR uses the maximum rated fan speed. Minimum noise and maximum airflow are different operating points.
  • These calculations compare particle-cleaning capacity. They do not promise health outcomes or removal of a specific gas.
