Levoit Core 300 vs Core 300P vs Core 300S
Levoit’s Core 300 product page now opens the Core 300-P listing, and the smart model in the family is sold as the Core 300S-P. Both ship with the same 3-stage Original filter and move almost the same amount of air.
Get the Core 300S for app control and lower power draw. Get the Core 300P to spend less.
Levoit lists two Core 300 models today. The Core 300-P delivers 143 CFM of clean air and the Core 300S-P delivers 141 CFM, both through the 3-stage Original filter. The 300S works with the VeSync app, Alexa and Google Assistant and is rated at 23 W. The 300P has button controls only, is rated at 56 W, and costs roughly 40 percent less on Amazon.

Which Model Is the Core 300?
Levoit’s original product address for the Core 300 (levoit.com/products/core300-true-hepa-air-purifier) now opens the Core 300-P listing, and that listing’s spec table gives the model as “Core 300” (checked October 2026). The smart model in the same family is the Core 300S-P. Amazon titles use the same names, Core300-P and Core300S-P.
Levoit’s current pages publish no separate specifications for the earlier Core 300, so the table above compares the two models Levoit lists today. If you own an earlier unit, the filter section below covers replacements.
What the Two Models Share
Both ship with Levoit’s 3-stage Original filter installed. Levoit lists a pre-filter for hair, dust and large particles, a main filter rated to remove 99.97 percent of particles down to 0.3 microns, and a high-density activated carbon layer for gases and odors.
Their airflow is within 2 CFM. At 4.8 air changes per hour, Levoit rates the 300S for 219 sq ft and the 300P for 222 sq ft. Both product pages list Sleep Mode.
Where the 300S Has the Edge
The 300S is the smart model. Levoit’s Core 300S-P page lists VeSync app control with schedules and a 1 to 24 hour timer, plus voice control through Amazon Alexa and Google Assistant.
Its rated power is 23 W against 56 W for the 300P. Running at full rated power around the clock for a year, that 33 W gap comes to about 289 kWh. The 300S is also rated at 22 dB on its lowest speed, two decibels under the 300P, and weighs 5.95 lb against 7.9 lb.
Where the 300P Has the Edge
The 300P costs roughly 40 percent less on Amazon for the same filter and 2 CFM more airflow. You set it with the buttons on the unit, so there is no app to install and no Wi-Fi network to join. For one room where you pick a speed and leave it, the 300P delivers the same filtration for less money.
Filters for Any Core 300 Model
The Core 300-P page lists four Levoit filters: the Core 300 Series Original Filter, a 3-Stage Pet Allergy Filter, a 3-Stage Toxin Absorber Filter and a 4-Stage Smoke Remover Filter. The Core 300S-P page lists the same optional Pet Allergy, Toxin Absorber and Smoke Remover filters.
Levoit’s Original filter page names different compatible models in different places. Before you order, match the compatibility line on the filter listing to the model number printed on your unit.
I own an earlier Core 300. Do I need a new unit?
Levoit has not published current specifications for the earlier model, so this page makes no performance comparison against it. If your unit runs and a replacement filter lists your model number, a new filter costs far less than a new purifier. The Core 300S-P is the upgrade if you want the VeSync app and voice control.
The Products
Levoit Core 300S
Best for buyers who want schedules and speed changes from a phone or a voice assistant, and for a room where the purifier runs all day at a 23 W rating. It ships with the 3-stage Original filter, and Levoit lists the Pet Allergy filter as an optional replacement.
Levoit Core 300P
Best for buyers who want the lower price and button controls with no app. It is the model Levoit’s Core 300 page now opens, and it ships with the same 3-stage Original filter as the 300S.
Frequently Asked Questions
How do the Levoit Core 300 and the Core 300P differ?
Levoit’s Core 300 product address now opens the Core 300-P listing, whose spec table gives the model as “Core 300”. Levoit’s current pages do not publish separate figures for the earlier version, so no CADR or wattage comparison is possible from Levoit’s own data. The 300-P is rated at 143 CFM and 56 W.
Can I use a Core 300P filter in my original Core 300?
Check the compatibility line on the filter listing against the model number on your unit. Levoit sells a Core 300 Series Original Filter, but its own filter page lists compatible models inconsistently.
Does the P in Core 300P mean it comes with a pet filter?
No. Levoit’s Core 300-P and Core 300S-P listings both show the 3-stage Original filter as pre-installed. The Pet Allergy filter is sold separately for either model.
Which model is best for a bedroom?
Both list Sleep Mode. The 300S is rated at 22 dB on its lowest speed against 24 dB for the 300P, and its app adds schedules and a timer you can set from bed. If the price gap matters more than the app, the 300P covers a room of the same size.
Which is best for allergies?
Both use the same Original filter, with a main stage rated to remove 99.97 percent of particles down to 0.3 microns, and their CADR differs by 2 CFM. Choose on price and app control. Levoit’s Pet Allergy filter is an optional replacement for both models.
