Current market
Each line carries its own check date because price, software, specifications, and product cycle do not age at the same speed.

Core 400S-P is coherent for a medium room when its 231 cfm smoke CADR and VeSync controls fit, after confirming current stock, exact filter and whether app benefits justify cloud dependency.

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.
Core 400S-P 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 direct-stock continuity, pm2.5 readings, app behavior, fan sound and exact cartridge cost 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.Owners discuss PM2.5 readings, app behavior, noise, filter life and direct-stock gaps across varied rooms. The reports are self-selected.
Confirm current authorized inventory and filter stock, then compare the sensor and sound at the speed needed for 4.8 ACH.

Levoit identifies exact model Core 400S as a 360-degree purifier with 231 cfm smoke CADR, PM2.5 display, VeSync automation and a bonded particle-plus-carbon cartridge.
$219.99 current VeSync U.S. price was retained for exact model Core 400S. Levoit direct has shown sold-out states while VeSync retains stock; verify seller, exact model and current delivery before paying
The model uses a Core 400S-P 3-stage bonded cartridge, with separate Original, Pet Allergy and Smoke Remover versions; the exact filter suffix and carbon loading matter Current ENERGY STAR data gives 231 cfm smoke, 240 dust, 259 pollen and 236 PM2.5 CADR with a 358-square-foot room basis. The maker's 1,718-square-foot figure is one ACH Levoit specifies about 22 to 52 dB, 38 W active and under 2 W standby; these are range endpoints, while annual energy depends on speed, auto behavior and runtime A laser particle sensor reports PM2.5 and drives auto mode. It cannot detect CO, CO2 and most gases and needs a clean sampling port
The Original 400S cartridge is commonly listed around $49.99 with six-to-twelve-month guidance; specialty media and current stock can raise annual cost Vacuum the outside of the cartridge, keep the circular intake and sensor clean, never wash bonded media, unplug for replacement and follow the reset procedure VeSync supplies remote control, schedules, history and voice integration through an account and cloud; review data handling and basic local behavior without Wi-Fi Levoit maintains the exact manual and genuine filters plus two-year limited warranty and 30-day return language; verify stock at both Levoit and VeSync
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.
The common-method table retains Core 400S exact performance, sound, energy, filter-cost and app columns and allows comparison without relying on room-size marketing.
Owners discuss PM2.5 readings, app behavior, noise, filter life and direct-stock gaps across varied rooms. The reports are self-selected.

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.
