Airmega ProX is the defended premium choice for a very large connected space when 568 cfm smoke CADR, low measured noise for its output and mechanical-only filtration justify its size and $199 annual filter set.

What changed
Older observations stay in the ledger when the current view changes. That lets a buyer tell the difference between an old complaint, an active issue, and a problem that was corrected.
Airmega ProX was checked against exact manufacturer identity and operating material, current U.S. price, filter availability and cost, room-size test basis, independent comparison and bounded owner evidence.
Each amount stays tied to its source and capture date. Conflicting prices remain visible until the seller resolves them.

Owner experience
Owner discussion returns to wheel and panel handling, large-room mixing, filter expense, measured noise and whether one unit reaches the full open plan rather than a universal air-quality outcome.
These are self-reported experiences from different room volumes, ceiling heights, layouts, sources, outdoor conditions, fan speeds, filter ages, placements, app versions, electrical conditions and individual sensitivities. They identify checks to run and do not prove exposure reduction, symptom improvement, gas removal, smoke safety, mold remediation, reliability or failure rates.Exact-model owners discuss wheel use, side panels, sound, large-room placement, sensor behavior and filter expense. Reports do not establish exposure or health outcomes.
Map the actual connected volume and obstructions, reserve both side clearances and compare one ProX with two independently placed smaller purifiers.

Coway identifies exact model AP-3522F as a 51-pound wheeled dual-filter purifier with 568 cfm smoke CADR, three particle-size readings, local automation and no app.

The ProX uses two washable pre-filters and two matched Max2 assemblies with HEPA and activated carbon; the genuine ProX set services both sides AHAM CADR is 568 cfm smoke, 580 dust and 450 pollen. Coway's 4,253-square-foot claim is one ACH and 2,126 square feet is two ACH; higher targets require a smaller room or additional clean-air delivery Coway specifies 23 to 46 dB(A) and 65 W across silent, levels 1–3, turbo, auto and eco. HouseFresh measured 462 cfm PM1 CADR at top speed and 299 cfm below 45 dBA in its 728-cubic-foot chamber PM1, PM2.5 and PM10 readings inform the display and auto response; those sensors do not detect carbon monoxide, carbon dioxide or every gas and need clean, unobstructed sampling
The genuine two-sided ProX set costs about $199 and is rated for roughly one year; high pollution can shorten life, and the bonded construction couples particle and carbon replacement Vacuum or wash and fully dry both pre-filters, wipe the sensors and cabinet, keep wheels and both intake doors clear, and replace both Max2 assemblies together ProX has no Wi-Fi, app or cloud account despite its premium price; all monitoring and control remain local Coway provides an exact U.S. manual, one-sheet, filter video, direct support and five-year family warranty language; confirm freight-return and in-home handling responsibilities
EPA treats portable filtration as a supplement to source control and clean-air ventilation, sizes particle cleaners by CADR and room volume, separates particle from gas filtration and states that no air cleaner removes every pollutant.
AHAM's suggested room size uses 4.8 air changes per hour and publishes separate tobacco-smoke, dust and pollen CADRs; room height and desired repetition remain part of sizing.
CARB certification addresses low ozone emissions and electrical safety under its regulation; CARB explicitly says listing does not establish cleaning effectiveness or complete health safety.
A purchased sample was tested at each speed for PM1 clearing, noise, energy and annual costs, with filter carbon mass and physical handling examined separately.
Exact-model owners discuss wheel use, side panels, sound, large-room placement, sensor behavior and filter expense. Reports do not establish exposure or health outcomes.

Manufacturer identity, exact filter and manual or support material, current U.S. price, AHAM or published CADR and room-size basis, independent comparative or instrumented editorial, CARB ozone context, EPA limitations and bounded owner evidence were checked on August 17, 2026. This desk covers complete current U.S.-market portable room air purifiers for serious home use. It excludes HVAC filters, industrial scrubbers, dehumidifiers, unsupported marketplace devices, filter-only products and cosmetic-only variants. CADR measures particle clean-air delivery under stated conditions; it is not a gas-removal rating, health guarantee or proof that one unit serves a whole home. Room-size headlines at one, two and 4.8 air changes per hour are not interchangeable. Sound, energy, filter efficiency, sensor readings, app features, auto modes, carbon labels, HEPA wording, CARB listing and ENERGY STAR status each have separate test boundaries. Source control and clean-air ventilation remain primary. No purifier prevents, treats or diagnoses illness, guarantees exposure reduction or smoke safety, remediates mold or assures universal indoor-air outcomes. Carbon monoxide alarms, moisture repair, professional hazardous-material work and public-health guidance remain separate needs.
