Find a purifier for the room and the way you use it.

Personal-space models here include the LV-H128 at 47 ft², Core Mini-P at 53 ft² and LV-H132 at 54 ft² at 4.8 ACH. Their separate one-change headlines are not equivalent room ratings. Open plans and high ceilings can change practical fit. The Coway Airmega ProX publishes 2,126 sq ft at 2 ACH rather than a direct 4.8-ACH rating; its 885-sq-ft comparison value is calculated from that rate and is the only current record above the optional 750-sq-ft extra-large threshold. Coway lists 1,643 ft² at 2 ACH for the Airmega 450; its approximately 685-ft² 4.8-ACH comparison is rate-scaled, not a direct manufacturer rating. The Airmega 400 comparison is about 650 ft² and the ProX about 885 ft². Coway Airmega 250/250S list 465 sq ft at 4 ACH and yield a 387-sq-ft 4.8-ACH comparison floor; the Art lists 440 at 4 ACH and yields 366. Neither figure is a direct 4.8-ACH manufacturer rating. Coway Airmega 250/250S list 465 sq ft at 4 ACH and yield a 387-sq-ft 4.8-ACH comparison floor; the Art lists 440 at 4 ACH and yields 366. Neither figure is a direct 4.8-ACH manufacturer rating. Coway Airmega 250/250S list 465 sq ft at 4 ACH and yield a 387-sq-ft 4.8-ACH comparison floor; the Art lists 440 at 4 ACH and yields 366. Neither figure is a direct 4.8-ACH manufacturer rating. The Blueair Blue Pure Mini Max Auto is directly listed at 105 ft² at 4.8 ACH, so it fits only the personal tier and falls below the 140-ft² compact threshold. Blueair's Classic Pro CP7i page directly lists 609 sq ft at 4.8 ACH; its larger hero and FAQ one-hour/30-minute claims differ, so use the repeated-cleaning figure when that rate is essential. Honeywell HPA6000 is listed at 398 sq ft at 4.8 ACH, enough for the medium tier but short of the 606-sq-ft large tier; do not use its separate, inconsistent 1-ACH headlines as a substitute.

This asks for a purifier sold with a fan function, not just the airflow every purifier produces. Unknown function status does not meet an essential requirement. Honeywell HPA6000 documents vertical, stationary directional-fan and full-room circulation positions; this is one purifier with a fan function, not an added separate fan or an air conditioner.

A separate cooling fan is not the same as a purifier with a built-in circulation-fan function. Shark TF202SHP includes one HP072 purifier and one TF202SWH fan; only the purifier receives the one-ACH room rating.

A purifier can deliver filtered air while heating, but it is not automatically a heater-size air-cleaning rating. Check floor placement, clearances, direct-power rules and mode-specific controls in the exact manual.

Choose manual-only if you require a model with no app functions; an app-connected product may still have physical buttons. Leave the answer open if connected control is optional.

This is about buttons or controls on the appliance, not whether a phone app also exists.

This is about automatic air-quality response, not app or voice control. Some purifier manuals identify particle sensing; the C535 manual identifies an odor/gas sensor. If sensor type matters to you, select a target below. A temperature-target Auto function does not qualify.

A sensor target is confirmed only where a model source identifies it. The C535 manual identifies its Auto sensor as detecting odorous gas; it does not document particle-sensor Auto. Shark HP162 manufacturer copy identifies VOC/odor-aware automatic response; that does not by itself establish a numeric PM2.5 readout or a strict TVOC sensor label. Shark HP062 exact copy identifies VOC/odor sensors but does not resolve a strict TVOC label or a particle-responding Auto target.

This is an occupancy/movement response that can raise fan speed, not an air-particle or VOC measurement. If motion-linked changes would be distracting, leave this optional choice open and read the review's control tradeoffs.

This means a purifier operating mode, not a selectable night light. Heater-enabled devices may disable Night mode while heat is active; requirements must fit one operating arrangement.

This is a purifier with a wake-up clock, not a general night-light or a promise of a sleep benefit. Blueair Mini Restful requires its app for alarm setup; see the exact review.

The Vital 100S-P and Vital 200S-P use color indicators and app updates, not a documented numeric PM2.5 display on the unit. The Coway Airmega 250 family has color-only unit feedback; the 250S app may show numeric particle values, but the unit itself remains non-numeric. A particle sensor is not a gas sensor. Some appliances change the number display by operating mode; if a numeric PM2.5 reading must remain visible during heat, the selected operating plan must support it. The Blueair Classic Pro CP7i toggles its local display among PM1, PM2.5 and PM10 readings one at a time; it is not a TVOC meter. Shark HP162’s page describes air-quality/VOC/particle information, but no numeric PM2.5 value on the unit is confirmed; keep qualitative levels distinct from a PM2.5 concentration. Shark HP062 adds local air/VOC/particle information, but its guide-level pollutant bands do not confirm an on-unit numeric PM2.5 concentration. The HP072 manual evidence is an HP070-family guide with a suffix/edition caveat; its Clean Air % is not a numeric PM2.5 reading.

The EverestAir-P physical control cycles through 45°, 60°, 75° and 90°; app controls can choose intermediate positions. Outlet direction does not remove the need for front intake clearance.

Wheels can help reposition a purifier on one floor, but do not change its weight or make it easy to carry upstairs.

Oil on a scent pad adds fragrance; it is not a gas sensor or a substitute for particle filtration. Follow the exact manual and never put oil on filter media.

A selectable night light is not necessarily dimmable. Check that the exact manual describes the light option and its off state.

The Sprout manual documents five Baby Sleep Mode presets and a default 30-minute light/sound routine; its app lets you customize preset and duration. This is an operating option, not evidence of a sleep or health benefit.

The Vital 100S-P and Vital 200S-P manuals document a 15-minute-high / 60-minute-medium Pet Mode cycle. That is different from the Vital Pet Pro’s automatic pre-filter cleaning, and its manual does not document the same fixed fan cycle.

Blueair PetAir Pro includes a Quilt Bed on top of the purifier. Blueair advertises it for pets up to 25 lb; its manual also warns that objects over 1.1 lb may activate Smart Mode. That is not phrased as a structural load limit, so check the exact guidance if the pet-weight interaction matters.

The PetAir Pro box must be emptied by hand; a soft brush/vacuum for the pre-filter is not included. A fur box does not remove hair from floors or upholstery.

PetAir's product page calls this Pet mode, while its manual describes Smart Mode, pet-weight input, a Silent Mode response and a separate Pet Lock button. This is not a fixed high/medium Pet Mode cycle.

Some models offer several selectable modes, but the manual may describe them as alternatives rather than concurrent behavior. This asks whether both behaviors are supported together in one operating arrangement.

The Vital Pet Pro runs the cycle daily by default and lets you adjust it in the app. The tray still needs emptying, and Levoit still recommends cleaning the screen every 2–4 weeks.

A pet-oriented filter package is not the same as a dedicated Pet Mode or control/display lock. The Vital Pet Pro lists a washable pre-filter and an activated-carbon/main filter; it does not identify the named Pet Allergy Filter with ARC Formula. Unknown package configurations do not satisfy an essential requirement.

The Core P350-P calls its feature Pet Lock; the Vital Pet Pro calls it Display Lock. Both prevent accidental button changes, but the Pro’s app can still adjust settings while its display lock is on.

Turbo is the highest-output and loudest fan setting in these manuals.

These are separate compatible replacement filters, not four filters or modes included in the purifier box. The Blueair Mini Max Auto's exact page offers a base Particle & Carbon selection, but its dedicated Mini Max replacement page omits 'Auto' in the compatibility statement; specialty replacements are not an essential match without confirmation.

A two-unit package can serve two separate rooms. Do not add room-area ratings together into a larger single-room claim. Shark HP072B2 contains two HP072 units, each rated 250 sq ft at 1 ACH; HP062B2 contains two HP062 units, each rated 300 sq ft at 1 ACH. Shark HP162B2 contains two HP162 units, each with a 750-sq-ft-at-1-ACH figure; do not treat this as one 1,500-sq-ft room.

A scent cartridge is different from a carbon filter. If box contents are not itemized, treat absence as unknown rather than assume the aroma can be removed after purchase.
