Clorox Medium Room True HEPA Air Purifier (11030J) review

Clorox’s Medium Room True HEPA Air Purifier is the 11030J, a compact floor-standing model whose most useful combination is a 225-square-foot five-change rating with particle-sensor Auto and a numeric PM2.5 display. Clorox also lists 1,000 square feet at one change per hour. That larger figure is a slower circulation rate; it should not be used as if the purifier can deliver five changes across 1,000 square feet. The product page says its room areas assume a closed room with an eight-foot ceiling and the highest speed. For this site’s 4.8-ACH comparison, 225 square feet is a conservative lower bound drawn from the stricter five-change rating, not a separate manufacturer claim.

Compact footprint, medium-room ceiling

The three listed CADRs are 148 CFM for smoke, 154 for dust and 160 for pollen. The 8.74-inch-square body stands 14.65 inches tall and weighs 5.97 pounds, so it is easier to reposition than the larger Clorox tower models. The five-change rating is still the boundary: a 300-square-foot room is above the page’s 225-square-foot fast-cleaning claim, even though the slower one-change number is much larger. If the room or open-plan area is bigger, compare the 11010 or a model with a more suitable repeated-cleaning rating rather than choosing from a headline maximum.

Automatic feedback and three filter layers

The 11030J uses a 360-degree three-stage filter: an outer pre-filter catches larger dust and pet hair, True HEPA captures 99.97% of particles as small as 0.3 microns, and active carbon reduces general odors. Clorox describes the filter as reducing viruses and bacteria as air passes through; that is not the same as killing them. The page cautions that results vary and does not support a medical promise.

Four fan speeds and sensor-based Auto let the purifier respond to the air-quality sensor instead of relying on manual speed changes. Its top display shows a PM2.5 reading, while the color light gives a six-level qualitative cue. The listing also documents a filter reminder, timer and child lock. A product-page caption claims the quiet setting is as low as 30 dB, but gives no measurement method or maximum level; treat it as a manufacturer claim for that setting, not a complete noise profile. The controls are on the unit; the exact listing does not identify app control, a UV-C stage or a dedicated Night mode. It is possible to dim or switch off the display/light at low speed, but that is not a separate automatic night program.

Filter planning and the 11030J identity

The box includes one filter, which Clorox estimates at six to twelve months depending on air quality. A filter-reminder light is a prompt to inspect service needs, not a live measurement of remaining media life. The 11030J product page itself does not name the cartridge, but Clorox’s separate 12030 filter page explicitly lists 11030J alongside 11030 and 11031. That is a manufacturer compatibility crosswalk, not an inference from the purifier’s model number. The filter page currently shows no availability, and no replacement price is established. This matters if you want to buy a used purifier or need a predictable supply of consumables.

The exact category card and BigCommerce product record identify SKU 11030J and UPC 040094110308; its product-page image label shortens the model to “11030.” The exact page itself presents the 11030J item, and the category shows Web Availability “ACTIVE” at capture. That establishes the observed identity and listing state, not current stock or price. If comparing search results, use the complete 11030J SKU/UPC rather than assuming every listing labeled 11030 is this exact configuration.

Where it sits in the Clorox range

Against the 11070 Medium Room Turbo, the 11030J gives up the explicitly timed Turbo function but adds sensor Auto and a numeric PM2.5 readout; their five-change areas are 225 and 215 square feet respectively. The Turbo+ 11071 adds Auto and a color indicator, but the reviewed listing does not document its numeric on-unit PM2.5 display. The 11030J is therefore a more informative small-room choice when seeing a particle value is important. Step up to the 11010 if its room rating is too small, or choose the 11070 if timed Turbo and a simple manual layout better fit. The 11030J works best for one modest room, an owner who values automatic particle response and local readings, and someone who checks the 12030 compatibility and seller availability before a purchase. Its room claim, replacement availability and low-speed noise caveats should be part of that decision, not hidden by the “medium room” label.
