Clorox 11010 vs Honeywell HPA300 Compared: Clorox offers particle Auto, Honeywell offers more smoke CADR at its manual Turbo

Check these before you buy

• Verify that the listing is the white US Clorox 11010 or the black US Honeywell HPA300, and check which filters come with it. The Clorox 11011 is a separate Alexa-enabled model, and the Honeywell HPA5300B is another model with different controls. Because the HPA300 manual also covers the smaller HPA090, HPA100 and HPA200, follow its HPA300 filter count and control instructions.
• Look at the exact model in the current offer, plus the seller, condition, included filters and return terms. Honeywell Store lists its own HPA300 as discontinued, but that says nothing about production status across the manufacturer or whether another seller has stock. This comparison makes no claim about current price, availability, delivery or an extra-filter bundle.
• The examples here all use smoke CADR. At the highest fan setting, Clorox publishes 206 CFM and Honeywell publishes 300 CFM. Dust ratings are 219 and 320 CFM respectively, and pollen ratings are 232 and 300 CFM. Do not add the three ratings together or put a dust figure in place of smoke. All of these describe particles and say nothing about gas removal.
• Take an illustrative room that is 18 feet long, 20 feet wide and 8 feet high. Its volume is 2,880 cubic feet. With a chosen sizing target of five filtered-air changes per hour, you need 2,880 times 5 divided by 60, or 240 CFM. The HPA300’s published maximum smoke CADR is above that figure and the Clorox’s is not. Five is a comparison target chosen for this example. It is neither a medical threshold nor a guarantee of clean air. The math sizes filtered air and does not cover fresh-air ventilation.
• In a second room that is 15 feet long, 15 feet wide and 8 feet high, the volume is 1,800 cubic feet. The same five-change target needs 1,800 times 5 divided by 60, or 150 CFM, which is under both maximum smoke ratings. Both units stay in the running, though this says nothing about how either performs at a lower speed. Results can shift with air mixing, room layout, open doors or windows, ongoing particle sources and filter condition. Neither example covers several connected rooms.
• Turn the Clorox on and use the Fan button to select Auto. The sensor then picks a fan speed based on the measured PM2.5 level. A manual speed is available instead. The published maximum is neither an Auto average nor a guaranteed minimum. The onboard reading does not certify the air in the whole room as safe, and it is not a gas detector. The shared manual’s Wi-Fi and Alexa instructions apply to the 11011 only.
• To run the HPA300 at its maximum speed, power it on and then choose Turbo, because the manual says it starts on Low. A second tap on Turbo goes back to the previous cleaning setting. Judge for yourself whether that operating sound is acceptable in the spot where it will sit. No matched noise measurements and no smoke CADR for quieter settings are part of this comparison.
• If you want the panel dark, use the light controls, which are separate from the fan. The Clorox light has On, Dim and Off, and Honeywell’s dimmer can turn its lights off while the purifier keeps running. The Clorox 11010 has a 1, 4 or 8-hour shutoff and the HPA300 a 2, 4 or 8-hour shutoff. Leave the timer unset if you want continuous operation. Neither timer schedules a later start.
• Set the Clorox on a level indoor surface with its air path unobstructed and away from water. It should not run in a greasy kitchen, near an open fire, or in a garage or any area with oil, solvents, insecticides or other chemicals. Use the adapter that comes with it. You also need room to unplug it, disconnect the adapter, turn it upside down and open the filter cover on the bottom. No numeric installed clearance is established here.
• The HPA300 should stand upright on a firm, level, flat indoor surface. Point the front away from the nearest wall or furniture and leave every grille unblocked. Bathrooms, laundry areas and other damp locations are off limits, as are spots near combustible gases or vapors. Plug it straight into a working wall outlet, never an extension cord or power strip, and leave room to take off the front grille and pull the filters. Before you run it, strip the wrappers from all filters and the prefilter, put in all three Type R HEPA elements with the tabs facing out and fit the Type A prefilter at the front.
• Start Clorox care by switching it off, unplugging it and disconnecting the adapter, and only then flip it over and open the bottom cover. Once a month, or more often if needed, vacuum the outside of the filter and the interior with a brush attachment. That is the documented cleaning method, so do not assume the filter can be washed with water. Detergent, solvents and spray cleaners are off the table. Look for clogging, reduced airflow or odors. The reminder appears after about 4,380 hours and asks you to inspect the filter. It does not mean you should throw it away automatically. The manual’s replacement guideline is a 6 to 12-month range, depending on condition. Use the specified 12010 replacement filter and reset the reminder once you have swapped it in.
• Before opening the Honeywell’s front grille for care, switch it off and unplug it. Its filters cannot be washed. Inspect them from time to time. The Type A prefilter is due for replacement about every three months and the three Type R HEPA elements about every twelve months, though condition and use set the real interval. Do not breathe in the collected dust. After you replace a filter, reset its matching reminder. Keep the area around the unit clean and wipe the exterior with a dry cloth. Filter cost and the number of pieces alone do not tell you the total annual running cost.
