Clorox 11010 vs Winix 5510: Auto triggered by particles or higher maximum CADR, with neither guaranteeing both
Quick verdict
If you want PM2.5-triggered fan changes and the Clorox 11010’s 206 CFM maximum smoke rating fits your room, that is the one to get. The Winix 5510 suits a target above 206 CFM and no higher than 253 CFM at manual Turbo, and it also suits anyone who wants Auto triggered by ordinary odors. Neither Auto mode guarantees maximum output, and the Winix drops below Low in Sleep when the room is dark. Both need a dry, open spot that you can still service. Keep the Clorox away from grease, open fires and oil or chemicals, and the Winix away from heat, steam, oily residue and flammable gases. Neither proves quiet-setting output or hazardous-gas protection, and neither pairs particle Auto with capacity above 206 CFM.
Before you buy
Why, and what it costs you
The same room can point toward a different sensor
A 15 by 15 by 8-foot den with a chosen target of five filtered-air changes per hour needs 150 CFM. Both maximum ratings pass that sizing check, so the trigger you want can break the tie. Clorox follows PM2.5, and Winix follows odorous gas. Neither automatic mode proves that rate is held, and neither sensor certifies the room as safe. If you would rather run a fixed manual speed, the sensor difference stops mattering.
Where this comes from
In Clorox’s manual, the PM2.5 reading drives the Auto fan levels. Winix Control Panel 14 identifies odorous gas, and section 10 sets the Auto speed range. This reversal leaves the room and the maximum ratings as they were, so the only change is the control routine you want. It adds no second capacity claim.
The catch
Clorox Large Room True HEPA
206 CFM is a maximum-speed smoke rating. In PM2.5-triggered Auto the fan can slow down, so a room-wide target isn't guaranteed. The display is neither a gas detector nor a medical-grade monitor. The Alexa features in the shared manual belong to the 11011, not to this 11010.
The catch
Winix 5510
You only get the 253 CFM smoke rating at maximum speed. Auto tracks odorous gas and uses Low, Medium or High, and light-triggered Sleep runs below Low. Neither mode, nor operation with PlasmaWave off, has a verified maximum rating here. The sensor is not a gas-safety monitor.

Clorox Large Room True HEPA
Why pick it
You want PM2.5-triggered fan changes, and the Clorox’s 206 CFM maximum smoke rating is enough for the room. Auto varies output and does not hold a room target. The reading it shows is not room-wide or medical-grade monitoring. Put it in a dry, unobstructed spot with filter access, away from greasy kitchens, open fires and oil or chemicals.
The catch
206 CFM is a maximum-speed smoke rating. In PM2.5-triggered Auto the fan can slow down, so a room-wide target isn't guaranteed. The display is neither a gas detector nor a medical-grade monitor. The Alexa features in the shared manual belong to the 11011, not to this 11010.
Your smoke-CADR target is above 206 CFM but not above 253 CFM, and you are fine with running the Winix on manual Turbo and with the sound that comes with it. Auto and Sleep do not reach the rated maximum, and the CADR with PlasmaWave off is unverified. Pick a dry, clear spot with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.
Auto triggered by ordinary odors appeals to you, and you accept lower output even though a 253 CFM maximum smoke rating fits the room. Auto leaves out Turbo, and Sleep in a dark room drops below Low. Auto does not use PM2.5 sensing and offers no hazardous-gas protection. The CADR with PlasmaWave off is unverified. The spot must be dry and clear, with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.
The catch
You only get the 253 CFM smoke rating at maximum speed. Auto tracks odorous gas and uses Low, Medium or High, and light-triggered Sleep runs below Low. Neither mode, nor operation with PlasmaWave off, has a verified maximum rating here. The sensor is not a gas-safety monitor.

What this page compares
Clorox 11010 and Winix 5510 compared on smoke CADR, particle sensing versus odor sensing, the limits of their automatic fan modes, night behavior and filter care.
Either could filter particles in a dry living room, bedroom or den, provided the rate you need is below their maximum ratings. Two separate questions change the choice. Does the room need more than 206 CFM, and do you want particles or odors to trigger fan changes? Both control panels have Auto, but that does not make the routines interchangeable.
Which one fits
Pick the situations that sound like you
Both maximum ratings fit, and I want fan changes triggered by fine particles
Winix has no PM2.5 trigger, and Clorox does. Its 206 CFM maximum can be used to screen the room, but Auto varies output and the reading is not room-wide safety monitoring. Choose a dry, clear spot with filter access, away from greasy kitchens, open fires and oil or chemicals.

Not suitable
My smoke-CADR target is over 206 and no more than 253 CFM
On manual Turbo, with sound you can accept, Winix covers this sizing range. Auto and Sleep (which runs below Low) don't establish its 253 CFM maximum, and a separate CADR with PlasmaWave off is unverified. Give it a dry, clear spot with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.

Winix 5510
Better fit
Both maximum ratings fit, and fan changes should be triggered by ordinary odors
Unlike Clorox, which triggers on PM2.5, Winix follows odorous gas. Auto leaves out Turbo and darkness can set off Sleep below Low, so the 253 CFM maximum is no promise of automatic output. A separate CADR with PlasmaWave off is unverified. It gives no hazardous-gas protection and needs a dry, clear spot with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.

Both have manual speeds, so the sensor difference no longer decides anything. Being similar means both stay in the running. It doesn't mean equal noise, energy use, odor removal or low-speed output. Check the speed you will run, permitted placement, the filter-care routine and the complete current offer.

Neither pairs PM2.5 Auto with a rating over 206 CFM, and both fall short above 253 CFM. Neither protects against hazardous gases. Keep airflow clear. Clorox must be kept away from grease, open fires and oil or chemicals, and Winix away from heat, steam, oily residue and flammable gases. Source control, ventilation and a carbon-monoxide alarm are still necessary.

Differences you will notice
01
The same room can point toward a different sensor
A 15 by 15 by 8-foot den with a chosen target of five filtered-air changes per hour needs 150 CFM. Both maximum ratings pass that sizing check, so the trigger you want can break the tie. Clorox follows PM2.5, and Winix follows odorous gas. Neither automatic mode proves that rate is held, and neither sensor certifies the room as safe. If you would rather run a fixed manual speed, the sensor difference stops mattering.
How we worked this out
In Clorox’s manual, the PM2.5 reading drives the Auto fan levels. Winix Control Panel 14 identifies odorous gas, and section 10 sets the Auto speed range. This reversal leaves the room and the maximum ratings as they were, so the only change is the control routine you want. It adds no second capacity claim.
02
A bigger room can outweigh your control preference
With the chosen five-change target, an 18 by 20 by 8-foot room needs 240 CFM. Winix passes that calculation only at its 253 CFM maximum-speed rating, which means manual Turbo and sound you can accept. Auto and Sleep are unverified at that rate, and so is separate PlasmaWave-off operation. Clorox’s 206 CFM maximum falls short. This is filtered-air sizing. It does not cover fresh-air ventilation and is no health guarantee.
How we worked this out
To get required CFM, multiply room volume in cubic feet by the chosen filtered-air changes per hour, then divide by 60. Both products are compared on the same smoke pollutant at the highest speed. Real-world layout, mixing, sources, openings and filter condition still matter.
03
Some requirements eliminate both
If you need PM2.5 Auto together with capacity above 206 CFM, this pair is out. Clorox offers the particle trigger. Winix offers the higher maximum rating along with an odor trigger. Neither passes the sizing check above 253 CFM. Easing a room or control requirement may reopen the choice, but it cannot supply quiet-output proof or make a prohibited placement acceptable. Neither extracts grease or protects against hazardous gas.
How we worked this out
Capacity, the automatic trigger, verified quiet output and permitted installation each stand as their own requirement. Phone control and a cheaper offer can't make up for one that fails. There is no established gas-removal comparison or current price advantage.
Plug in your numbers
Can either purifier keep up with your room?
This checks hard limits only. Personal preferences are left out of the math.
Clorox Large Room True HEPA
Works with your numbers
206 CFM of verified clean-air delivery works out to about 5.2 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
Winix 5510
Works with your numbers
253 CFM of verified clean-air delivery works out to about 6.3 air changes per hour in this room. Hitting the 5 ACH target takes 200 CFM.
This uses each model’s pollutant-specific CADR at top speed and a target of five air changes per hour. Quieter settings clean less air. Raw airflow and one-change coverage claims are never swapped in.
Option A
11010
Clorox, 11010
Large Room True HEPA
Clorox 11010 has a maximum smoke CADR of 206 CFM, PM2.5-triggered Auto, four manual speeds and a separate light control. Reaching the filter at the bottom means unplugging it, disconnecting the adapter and turning it over. Greasy kitchens, open fires and oil or chemical areas are excluded.
Best for
You want PM2.5-triggered fan changes, and the Clorox’s 206 CFM maximum smoke rating is enough for the room. Auto varies output and does not hold a room target. The reading it shows is not room-wide or medical-grade monitoring. Put it in a dry, unobstructed spot with filter access, away from greasy kitchens, open fires and oil or chemicals.

Filter access and recurring care: Bottom access after unplugging, disconnecting the adapter and inverting
Winix 5510 has a maximum smoke CADR of 253 CFM, odorous-gas Auto and a slower Sleep mode triggered by light. Maximum output needs manual Turbo. Phone control is optional once compatible Wi-Fi and pairing are in place. Its prefilter needs cleaning, while carbon and HEPA get replaced.
Best for
Your smoke-CADR target is above 206 CFM but not above 253 CFM, and you are fine with running the Winix on manual Turbo and with the sound that comes with it. Auto and Sleep do not reach the rated maximum, and the CADR with PlasmaWave off is unverified.

In practiceSome room-volume targets are above Clorox’s maximum but within Winix's reach. Compare the same smoke-particle rating at the highest speed. These ratings measure clean-air delivery, not raw fan airflow or gas removal, and they say nothing about Auto or quiet-setting output.
What happens when the room darkens

In practiceOn Clorox, you can darken the panel without touching the fan selection. Winix's automatic night routine alters the fan along with the lights. Don't base a purchase that depends on capacity on reduced Sleep output, and don't mistake a dark panel for measured quiet performance.
Filter access and recurring care

Winix 5510Front access to a reusable prefilter and replaceable carbon plus HEPA
In practiceNeither is hands-off. Leave enough room to service the unit and be ready for the cleaning routine. A reusable prefilter doesn't make Winix's whole filter set washable. Clorox’s reminder is a prompt to inspect the filter, and it does not tell you to throw it out right away.
Placement and wall clearance

Winix 5510Hard flat surface and 12 to 18 inches from walls
In practicePlan around the space the unit needs once installed, which is more than the cabinet width. Winix gives a numeric wall clearance for maximum airflow. For Clorox no numeric clearance is verified here, though it still needs a clear air path and access to the bottom for service. Neither should go near grease, chemical fumes or blocked vents.
Trade-offs
What each pick costs you
With Clorox Large Room True HEPA
Set it on a level, dry indoor spot with clear airflow, away from greasy kitchens, open fires and oil or chemicals. For routine filter care, unplug the unit, disconnect the supplied adapter and turn it over. Follow the vacuum-cleaning instructions and replace filters according to their condition.
With Winix 5510
Place it on a hard, flat, dry surface with 12 to 18 inches from walls and room at the front, away from heat, steam, oily residue and flammable gases. Run it on 120V with no other appliances sharing the outlet or power supply. Clean the prefilter and replace the nonwashable carbon and HEPA filters.
Change of plan
When the answer changes
Particle-triggered Auto matters, and a 206 CFM maximum smoke CADR suits the room
Go with Clorox Large Room True HEPA. Clorox has that particle trigger, but Auto guarantees neither its 206 CFM maximum nor a room-wide target. Choose a dry, clear spot with filter access, away from greasy kitchens, open fires and oil or chemicals. Its reading does not count as safety monitoring.
The target is above 206 and at most 253 CFM, and manual Turbo is fine
Go with Winix 5510. Winix reaches its 253 CFM maximum only with manual Turbo, so the sound has to be acceptable to you. Output in Auto, in Sleep and with PlasmaWave off is not established at that rate. Choose a dry, clear spot with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.
Everyday odors should trigger Auto, and lower output in automatic mode is acceptable
Go with Winix 5510. Auto on the Winix tracks odorous gas and leaves out Turbo. It does not track PM2.5. Darkness can put it into Sleep below Low, so neither mode guarantees the 253 CFM maximum. CADR with PlasmaWave off is unverified. It gives no hazardous-gas protection. Give it a dry, clear spot with 12-to-18-inch wall clearance and filter access, away from heat, steam, oily residue and flammable gases.
Something is not met: the combined need for particle Auto and capacity, quiet-output proof or safe placement
Neither model fits. Neither combines particle Auto with capacity above 206 CFM, goes beyond 253 CFM, or proves quiet-setting output. Neither gives hazardous-gas protection. Airflow has to stay clear. Clorox rules out grease, open fires and oil or chemicals, and Winix rules out heat, steam, oily residue and flammable gases.
Decision guide
Before you buy
Work out the particle rate your room requires at a speed you will use. After that, choose what should trigger automatic fan changes, particles or odors.
Check these before you buy
Make sure the listing is the white US Clorox 11010 or the dark US 120V Winix 5510, and see which filters are really included. The Clorox 11011 is the separate Alexa model. The Winix 5500-2 is another model, and the 5510 manual is shared with the different-looking 5520. Review the current seller, condition, filter package and return terms. Nothing here claims a current price, availability, delivery, extra filter bundle or remote handset.
Stick to smoke CADR throughout this comparison, which is 206 CFM for Clorox and 253 CFM for Winix at the highest fan speed. The separate dust ratings are 219 and 252 CFM, and the pollen ratings are 232 and 247 CFM. Do not add the pollutants together or put dust in place of smoke. CADR measures filtered-air delivery. It is not raw fan airflow, gas-removal capacity or a medical outcome.
Consider an illustrative room that is 18 feet long, 20 feet wide and 8 feet high. It contains 2,880 cubic feet. Reaching a chosen target of five filtered-air changes per hour takes 2,880 times 5 divided by 60, or 240 CFM. The Winix’s 253 CFM maximum smoke rating passes that sizing check and the Clorox’s 206 CFM does not. The target of five is chosen for comparison and is not a medical threshold. This sizes filtered air and does not cover fresh-air ventilation.
A 15 by 15 by 8-foot room has a volume of 1,800 cubic feet, so the same chosen target requires 1,800 times 5 divided by 60, or 150 CFM. Both maximum ratings pass this check. Neither unit is established to deliver 150 CFM in Auto, Sleep or any other lower setting. Real results depend on layout, air mixing, open doors or windows, ongoing sources and filter condition. Connected rooms and whole homes are outside what these examples size.
To get particle-triggered changes on the Clorox, power it on and select Auto with the Fan button. A PM2.5 table sets the fan level from the onboard reading. Four manual speeds are available if you would rather choose one yourself. Because Auto can lower the speed, it does not establish a chosen room-wide target or continuous maximum output. The numeric display and the colors are not a medical-grade measurement, a gas detector or proof that the room is safe.
On the Winix, keep the odorous-gas Smart Sensor and the ambient-light sensor apart. Auto picks Low, Medium or High based on the gas reading, while Turbo is a manual speed of its own. According to the product page, darkness triggers Sleep and returning light brings Auto back. Sleep runs at a speed below Low and turns the air-quality LED off. No verified 253 CFM smoke rating is established for any of those automatic modes. Responding to odor is not the same as responding to PM2.5 or protecting against hazardous gas.
On the Clorox, the Light button offers On, Dim and Off and does not lower the fan you selected, although in Auto the particle reading can still change the speed. On the Winix, Sleep is triggered by light and deliberately slows the fan. When your room needs maximum-speed output, pick the operating mode you will really use and check it against that need. This comparison has no matched noise measurements and no verified lower-speed CADR.
Winix Smart phone control requires compatible Wi-Fi and app pairing, but local operation works without pairing. The Wi-Fi button toggles connectivity, and holding it for three seconds starts pairing. PlasmaWave gets its own on/off button, and Sleep turns it off at first, though you can turn it back on. Neither a separate PlasmaWave-off CADR nor an automatic return to a preferred setting after every restart is established. The shared manual does not give the Clorox 11010 the Alexa features of the 11011.
The Clorox belongs on a level, dry indoor surface with unobstructed airflow and no water nearby. Power it with the adapter that comes with it. It should not run in a greasy kitchen, near an open fire, or in a garage or any other area with oil, solvents, insecticides or other chemicals. Leave enough space to unplug it, disconnect the adapter and turn the unit over to reach the filter on the bottom. No numeric installed clearance is established here. When you install a replacement filter, take its protective packaging off first.
Set the Winix on a hard, flat, dry indoor surface out of direct sunlight, leaving 12 to 18 inches between it and the walls for maximum airflow and clear access to the filters at the front. Do not block the vents, lay the unit on its side or put it under an electrical outlet, and avoid heat, steam, oily residue and flammable gases nearby. It runs on 120V, and no other appliance should share its outlet or power supply. Remove the filter wrapping first, then install HEPA at the back, AOC carbon in the middle and the prefilter at the front.
Caring for the Clorox starts with turning it off, unplugging it and disconnecting the adapter before you turn it over. Each month, or more often if needed, vacuum the outside of the filter and the interior with a brush attachment. Stick with that method, since wet washing is not something to assume is allowed. Detergent, solvents and spray cleaners should not be used. Its roughly 4,380-hour reminder is a prompt to inspect the filter. It does not mean you should discard it automatically. Look for clogging, reduced airflow or odors, and follow the 6 to 12-month replacement guideline based on condition. When you replace it, fit a 12010 and reset the reminder.
To care for the Winix, unplug it and let it cool. The prefilter should be cleaned with a vacuum or soft brush every 14 days. If it is excessively soiled, and only then, rinse it in room-temperature water without soap or detergent and give it at least 24 hours to dry. The carbon and HEPA filters are not to be washed, and their roughly twelve-month replacement interval depends on the environment. Replacements are Filter Q, 1712-0123-00. Afterward, refit the prefilter, close the front and, with the unit on, hold Filter Reset for at least five seconds. A washable prefilter or the number of filters does not by itself tell you the annual running cost.
What this page can’t tell you
Published specifications and operating instructions for the exact models are the basis here. Noise, energy, reliability, sensor accuracy, odor removal and health outcomes were not tested hands-on.
A maximum smoke CADR promises nothing about output in Auto, Sleep, a quieter setting or another PlasmaWave state. And a sensor reading does not show that all the air in the room has passed through the filter.
Treat the stated room dimensions and the five-change target as illustrative assumptions. They do not set a safe-exposure threshold, guarantee a room-wide particle level or establish a fresh-air ventilation rate.
A PM2.5 display does not amount to medical-grade room monitoring, and an odorous-gas sensor is no gas-safety monitor. Neither purifier substitutes for source control, appropriate ventilation or a carbon-monoxide alarm, and neither makes a prohibited placement acceptable.
