The verdict
The Core 300-P is a compact 143 CFM air purifier for a bedroom or home office up to 222 ft². Its $29.99 filter lasts 6 to 8 months, so filters run about $45 to $60 a year. The catch is thin data: one CADR figure, one power rating and no AHAM, CARB or Energy Star listing that could be confirmed.
The trade-off
Levoit publishes one CADR and one power figure, and no independent listing for it could be confirmed.

About this price
Regular price on Levoit's Core 300-P Black listing. The regular price shown was the same, so there was no sale, and the page had an Add to cart button on Oct 13, 2026. Levoit's main Core 300-P listing is $99.99 but doesn't name a color. Shipping is free. Price is before tax.
A GOOD FIT FOR
A bedroom or home office up to 222 ft² where floor space is tight.
- A bedroom or home office up to about 220 ft²
- A tight spot; it's 8.7 in square and weighs 7.9 lb
- You want simple controls on the unit, with a sleep mode and timer
- You want the option of a pet, smoke or toxin filter
- You're fine with filter costs of about $45 to $60 a year
THINK TWICE IF
- A living room or open-plan space; the 1,066 ft² figure assumes one air change an hour
- You want app control or an air-quality readout; the Core 300-P's feature list has neither
- You want an AHAM, CARB or Energy Star listing for it that you can check before buying
- You want to know its power draw or noise at each speed before you buy
What still needs checking
- Whether AHAM's Verifide directory lists it, and with which smoke, dust and pollen CADR
- Whether CARB certified it; the readable part of CARB's list didn't reach it
- Which pollutant the 143 CFM figure refers to
- Power draw at each fan speed and in standby
- Noise at each fan speed
- Clearance and pre-filter care advice, because the manual PDF has no readable text
- How the Pet Allergy filter differs from the standard filter
- Which color ships from the $99.99 main listing
- Whether opened filters can be returned
The practical details.

|---|---|
| CADR | 143 CFM; Levoit gives one figure, not separate smoke, dust and pollen ratings |
| Room size | 222 ft² at 4.8 air changes an hour; 1,066 ft² at 1 |
| Noise | 24 to 54.5 dB; 26 dB or less in sleep mode, per the filter pages; no per-speed figures |
| Power draw | 56 W rated at 120 V; no high, low or standby figures |
| Filters | One 3-stage filter: pre-filter, main filter and activated carbon |
| Filter life and price | 6 to 8 months; $29.99 standard, $35.99 Pet Allergy or Toxin Absorber, $39.99 Smoke Remover |
| Controls | Sleep mode, a 2 to 8 hour timer and a check-filter indicator; the feature list has no app or air-quality sensor |
| Size and weight | 8.7 × 8.7 × 14.2 in; 7.9 lb |
| Dimensions | 8.7 × 8.7 × 14.2 in, or 22 × 22 × 36 cm. It weighs 7.9 lb (3.6 kg). |
| Materials | It has three stages: a pre-filter for hair, dust and large particles, a main filter, and a high-density activated carbon filter for gases and odors. All three come as one replaceable filter. Levoit says the main filter removes 99.97% of ultrafine particles down to 0.3 μm. Its HEPA claim covers sleep mode only and cites an unnamed independent lab test to IEST RP C001.7. Levoit doesn't name the main filter's media. The product pages call it ozone free. |
Before you buy

No installation. It's a freestanding unit that plugs into a 120 V, 60 Hz outlet. Levoit lists an operating range of 14 to 104°F and humidity below 85%. The product pages give no clearance advice, and the linked manual PDF has no readable text.
Warranty2 years from the original purchase date, covering defects in materials and workmanship
2 years from the original purchase date, covering defects in materials and workmanship. In California the period starts on delivery or pickup. Registration isn't required, and the warranty doesn't transfer to a later owner. Filters count as wear items and aren't covered, and neither is commercial or rental use. Units from unauthorized sellers don't qualify. Claims go through support.levoit.com and need proof of purchase with the invoice or order ID. The warrantor, Arovast, chooses whether to refund, repair or replace it.
ReturnsLevoit offers a 30-day money-back guarantee on direct purchases, counted from delivery
Levoit offers a 30-day money-back guarantee on direct purchases, counted from delivery. The unit must go back in its original condition and packaging, with all accessories and a copy of the invoice. Excessively worn, used or altered items are refused. Levoit sends a prepaid label and an RMA number once it approves the return, and you have 15 days to ship it. Refunds go to the original payment method within 30 days of receipt. The policy doesn't mention filters or restocking fees.

Recorded recurring parts and refills:
- Core 300 Series Original Filter: $29.99 every 8 months. One 3-stage filter, part Core 300-P-RF. Levoit recommends replacing it every 6 to 8 months. That's $44.99 a year at 8 months, or $59.98 at 6. Levoit lists it as compatible only with the Core 300-P, Core P350-P and Core 300-P-RAC. Other text on the page also names the Core 300S-P. A 2-pack lists at $54.99 but was sold out.
- Core 300-P 3-Stage Pet Allergy Filter (optional): $35.99 every 8 months. One filter. Levoit describes its three stages the same way as the standard filter's and gives the same 6 to 8 month advice. At 8 months it costs $9 more a year than the standard filter.
- Core 300-P 3-Stage Toxin Absorber Filter (optional): $35.99 every 8 months. One filter, part Core 300-RF-TX, sold for smoke, smog and VOCs. Same three stages and the same 6 to 8 month advice. At 8 months it costs $9 more a year than the standard filter.
- Core 300-P 4-Stage Smoke Remover Replacement Filter (optional): $39.99 every 8 months. One filter, part Core 300-RF-SR, with 2 extra dual-sided pre-filters. It adds a fourth stage and a carbon blend Levoit calls ARC Formula. Same 6 to 8 month advice. At 8 months it costs $15 more a year than the standard filter.
- Purchase is the $104.99 regular price on Levoit's Core 300-P Black listing, with no sale shown. Levoit's main Core 300-P listing is $99.99 and doesn't name a color.
- Filters come to $44.99 a year. That's one $29.99 standard filter every 8 months, the long end of Levoit's advice. Three years of purchase and filters comes to $239.96 before electricity.
- Changing the filter every 6 months raises filters to $59.98 a year. Three years then comes to $284.93.
- Watts is Levoit's 56 W rating. Levoit doesn't give draw at each speed or say how many hours a day to run it. For scale, 56 W around the clock is about 1.34 kWh a day, or 491 kWh a year. Energy cost isn't estimated.
- Levoit lists no subscription or other recurring fee. Its filter pages offer a recurring-delivery option, but these figures use the one-time price.
Evidence & sources.
Do air purifiers work? Our evidence review grades the research as Strong. That grade is about the claim, not about this product.
- Manufacturer claimLevoit rates the Core 300-P at 143 CFM, for a 222 ft² room at 4.8 air changes an hour.12 Levoit's own figures. The product pages name no test lab and give no smoke, dust and pollen split. The 1,066 ft² figure is the same airflow at one air change an hour.
- Manufacturer claimLevoit's filter pages say the main filter removes 99.97% of particles down to 0.3 μm, and that the purifier reaches HEPA-level efficiency in sleep mode.356 The footnote cites an independent lab test to IEST RP C001.7. The lab isn't named and no report is linked. Filter efficiency isn't the same as CADR, which measures how fast the unit cleans a room.
- Manufacturer claimLevoit's product pages say the Core 300-P is CARB compliant, FCC certified and ETL listed.12 The main listing shows CARB and Intertek logos but gives no executive order number. Neither page mentions AHAM Verifide or Energy Star.
- Regulator recordThe readable part of CARB's list of certified air cleaning devices showed five Levoit entries, none of them a Core 300 model.9 The Levoit entries were LAP-P201S-WUS (EO G-26-121, Jun 2, 2026), LAP-P501S-WUSR (G-26-117, May 18, 2026) and three LAP-C171 models (G-26-118, May 18, 2026). The page text cut off mid-table, and the part read held entries notified from October 2025 to June 2026. The Core 300-P may be listed further on, so its CARB status is unconfirmed rather than missing.
- Regulator recordA search of ENERGY STAR's certified room air cleaner data for Levoit returned 10 models, none of them a Core 300 or Core 300-P.10 No record mentioned Core 300, 300-P or C301. Without a listing, there are no certified smoke, dust and pollen CADR or yearly energy figures for it.
- CertificationAHAM's Verifide directory couldn't be checked for the Core 300-P.11 The directory loads by JavaScript, and the page text was only a notice saying so. Levoit doesn't claim AHAM Verifide for this model, so its listing status is unknown.
