Main trade-off
Clorox Large Room True HEPA
Auto follows a particle reading rather than a user-selected minimum room-air-change target.
Head-to-head
Clorox 11010 vs Levoit Core 300-P: Clorox adds particle Auto, both need maximum speed for rated CADR
The short answer
Choose Clorox 11010 for PM2.5-triggered fan changes or a smoke-CADR target above 143 and at most 206 CFM. Choose Core 300-P when 143 CFM suffices, manual control suits you and its complete original-filter kit costs less. Both ratings require maximum speed and clear airflow, not Auto or Sleep. Levoit needs 15 inches on all sides. Clorox excludes greasy kitchens, open fires and oil or chemical areas. Neither establishes hazardous-gas protection or the rated output at a quiet setting.
Before you choose
The reasoning and the trade-offs
A 300-square-foot study can separate these ratings
A closed 300-square-foot study with an 8-foot ceiling needs 200 CFM for a chosen five-air-change target. Clorox’s 206 CFM clears that calculation at maximum speed, while Levoit’s 143 does not. Auto or Sleep cannot be substituted. Below 143 CFM both qualify, and above 206 neither does. This is filtered-air sizing, not ventilation or a health guarantee.
What this is based on
Calculation: 300 × 8 × 5 ÷ 60 = 200 CFM. It compares manufacturer smoke CADR with an explicit sizing target, not a measured room result.
Main trade-off
Levoit Core 300-P
No automatic particle-triggered fan change is documented for the base Core 300-P.
Clorox Large Room True HEPA
- Choose it for
- Your smoke-CADR target exceeds 143 but not 206 CFM, and you will use Clorox at maximum speed with clear airflow. Auto does not guarantee that output. The dry, level location must exclude greasy kitchens, open fires and oil or chemical areas. If 143 CFM suffices, capacity alone stops deciding.
- You want PM2.5-triggered fan changes and accept variable Auto output, not a guaranteed room-air-change target. Clorox needs dry, level placement and clear airflow away from greasy kitchens, open fires and oil or chemicals. Its sensor adds little if you plan a fixed manual speed.
- Main trade-off
- Auto follows a particle reading rather than a user-selected minimum room-air-change target.
Levoit Core 300-P
- Choose it for
- The original-filter Core 300-P costs less as a complete kit, manual control suits you and 143 CFM at maximum speed meets your room target. Allow 15 inches on all sides with clear airflow. Sleep output is unverified. A need for more airflow or automatic particle response rules it out.
- Main trade-off
- No automatic particle-triggered fan change is documented for the base Core 300-P.
About this comparison
Compare rated particle airflow, automatic fan response and the placement space these two purifiers need before choosing for your room.
These are plausible alternatives for a bedroom or study where you want local controls rather than an app. The useful questions are how much rated particle airflow the room needs and whether the fan should respond to particles without a button press. They are separate decisions.
Winner by situation
Start with what you need it to do
My room needs 200 CFM for the target I chose
At a 200 CFM sizing target, Clorox clears the calculation only at its rated maximum speed with clear airflow. Levoit’s 143 CFM cannot. Auto is not a 206 CFM promise, and the Clorox location must stay dry and exclude grease, open fires and oil or chemicals.
- Clorox Large Room True HEPA
- Better fit
- Levoit Core 300-P
- Not suitable
I want the fan to respond to detected particles
Clorox adjusts its fan from the onboard PM2.5 reading. Levoit leaves speed selection to you. Accept changing airflow and a safe, clear location away from greasy kitchens, open fires and oil or chemicals, rather than treating Auto as a fixed room-air-change setting.
- Clorox Large Room True HEPA
- Better fit
- Levoit Core 300-P
- Not suitable
143 CFM is sufficient and I prefer manual control
Both remain candidates at a 143 CFM target, using maximum-speed ratings. Core 300-P becomes the saving only if its complete original-filter kit actually costs less, manual control suffices and 15-inch all-side clearance works. Sleep is not established at that rate.
- Clorox Large Room True HEPA
- Good
- Levoit Core 300-P
- Good
I need the rated airflow while it stays quiet
Neither maximum-speed rating establishes output at your required quiet or automatic setting. Seek measurements at that exact setting. A target above 206 CFM also exceeds both, and a particle rating or PM2.5 display does not establish protection against gases.

Only an enclosed narrow shelf is available
Levoit needs 15 inches of clearance on all sides. No evidence here establishes Clorox’s suitability inside the shelf. Do not block the inlets or outlet, and retain underside filter-service access. Find a different location before buying.

What matters in practice
The differences that matter
A 300-square-foot study can separate these ratings
A closed 300-square-foot study with an 8-foot ceiling needs 200 CFM for a chosen five-air-change target. Clorox’s 206 CFM clears that calculation at maximum speed, while Levoit’s 143 does not. Auto or Sleep cannot be substituted. Below 143 CFM both qualify, and above 206 neither does. This is filtered-air sizing, not ventilation or a health guarantee.
How we reached this conclusion
Calculation: 300 × 8 × 5 ÷ 60 = 200 CFM. It compares manufacturer smoke CADR with an explicit sizing target, not a measured room result.
An automatic fan is not an automatic room-size guarantee
Particle-triggered adjustments can spare trips to the Clorox controls, but the fan may slow as its PM2.5 reading falls. That makes Auto a different job from maintaining a fixed filtered-air target. If you prefer a steady manual speed, the sensor loses its value and a lower-priced Core 300-P remains relevant when its maximum-speed 143 CFM rating and placement fit.
How we reached this conclusion
The Clorox manual ties Auto to a particle sensor. Levoit’s exact base-model instructions offer manual speeds and Sleep, not the app and sensor features of 300S.
A small cylinder still needs open space
Levoit’s small body does not qualify it for a tight shelf: it still needs 15 inches on every side. Both need open airflow and underside filter-service access. No numerical Clorox clearance establishes that it fits a narrower opening. If neither can breathe or be serviced at the chosen spot, change the location before buying.
How we reached this conclusion
The exact operating and filter-care instructions take precedence over the closed cabinet dimensions.

Clorox Large Room True HEPA
Fits these inputs206 CFM of verified clean-air delivery gives about 5.2 air changes per hour here. The 5 ACH target needs 200 CFM.
Levoit Core 300-P
Does not fit these inputs143 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.
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
Clorox, 11010
Large Room True HEPA
Clorox 11010 offers 206 CFM rated smoke-particle airflow and PM2.5-based Auto control. Auto can reduce fan speed, so it is not a fixed-flow promise. Keep airflow clear and exclude greasy or chemical-storage locations.
- Best matched use
- Your smoke-CADR target exceeds 143 but not 206 CFM, and you will use Clorox at maximum speed with clear airflow. Auto does not guarantee that output. The dry, level location must exclude greasy kitchens, open fires and oil or chemical areas. If 143 CFM suffices, capacity alone stops deciding.
Checked facts
- Smoke-particle CADR: 206 CFM rated
- Who changes fan speed: PM2.5-based Auto or four manual speeds
- Placement and filter access: Level surface, clear airflow and room to turn over for filter care
Choice B
Levoit, Core 300
Core 300-P
Core 300-P provides 143 CFM rated smoke-particle airflow with manual speeds. It needs 15 inches of clearance on all sides despite its smaller body. Its original-filter rating does not establish Sleep-mode flow.
- Best matched use
- The original-filter Core 300-P costs less as a complete kit, manual control suits you and 143 CFM at maximum speed meets your room target. Allow 15 inches on all sides with clear airflow. Sleep output is unverified. A need for more airflow or automatic particle response rules it out.
Checked facts
- Smoke-particle CADR: 143 CFM rated
- Who changes fan speed: Three manual speeds and Sleep
- Placement and filter access: 15-inch all-side clearance, clear airflow and underside filter access
Meaningful differences
What changes the fit
| What changes | Clorox Large Room True HEPA | Levoit Core 300-P | Why it matters |
|---|---|---|---|
| Smoke-particle CADR | 206 CFM rated | 143 CFM rated | Compare the same pollutant rating. These numbers are not promises for Sleep or an automatically reduced speed. |
| Who changes fan speed | PM2.5-based Auto or four manual speeds | Three manual speeds and Sleep | Clorox can react to a particle reading. Levoit requires you to choose a speed. Auto does not hold a chosen room-air-change target. |
| Placement and filter access | Level surface, clear airflow and room to turn over for filter care | 15-inch all-side clearance, clear airflow and underside filter access | The 8.7-inch Levoit body still needs operating space. Neither should be selected by cabinet width alone. |
What you give up
Every choice has a cost
If you choose Clorox Large Room True HEPA
- Greasy kitchens and areas with oils or chemicals are excluded by the manual.
If you choose Levoit Core 300-P
- 15-inch all-side clearance matters more than the small cabinet when locating it.
Recommendation switch
The decision flips if...
Required rated airflow exceeds 143 CFM but stays within 206 CFM
Choose Clorox Large Room True HEPA. The extra capacity is useful only with maximum-speed operation and unobstructed airflow in a dry, level location away from grease, open fires and oil or chemicals. Clorox Auto cannot guarantee the 206 CFM maximum.
Particle-triggered fan changes matter more than steady airflow
Choose Clorox Large Room True HEPA. Its PM2.5-triggered Auto can spare manual adjustments, provided variable airflow is acceptable and placement is dry and clear, away from grease, open fires and oil or chemicals. It is not a fixed room-air-change control.
143 CFM meets the brief and lower-priced manual control is enough
Choose Levoit Core 300-P. The saving applies only to a lower-priced complete original-filter kit, with manual control, maximum-speed operation and 15 inches of clear space on every side. Sleep does not inherit the 143 CFM rating.
The required setting has no supporting airflow evidence
Choose neither. Look elsewhere for a target above 206 CFM, proven quiet-setting output or hazardous-gas protection. Neither particle CADR nor an onboard reading resolves those requirements.
What matters in practice
Before you choose
Size for the airflow you need, then decide whether a particle-triggered fan change is useful. Do not treat Auto as a guaranteed flow setting.
What this comparison cannot tell you
- No hands-on noise, purification-speed or sensor-accuracy testing was performed.
- Rated airflow is not verified for quiet or automatically changing settings. No gas-removal or medical outcome is promised.
- The manufacturer’s large-area marketing and rounded room labels use different turnover assumptions. The worked room calculation uses explicit volume instead.
