IQAir Atem X

The AHAM certified directory of October 2023 lists the Atem X with a tobacco smoke CADR of 415, a dust CADR of 436, a pollen CADR of 450 and an optional PM2.5 CADR of 425. IQAir's own airflow per fan speed runs 65, 115, 162, 206, 265, 324, 383 and 471 cfm.

AHAM certified room size, derived under ANSI/AHAM AC-1. IQAir also markets the Atem X for rooms up to 1650 sq ft (154 m²), a figure at a lower air-change rate.

Eight manual fan speed levels set from the touch slider, plus three smart mode profiles (Quiet, Balanced and Max) that drive the speed from the sensors.

Sound pressure at 3.3 ft across the eight fan speeds: 15, 18, 24, 33, 37, 43, 48 and 58 dB(A).

Draw at fan speed 8. The eight speeds are rated at 6, 7, 9, 12, 21, 34, 57 and 86 W, with networked standby below 1.8 W.

Smart mode sets the fan speed from the live sensor readings. Three profiles are selectable in the app: Quiet caps the fan at speed 5, Balanced at speed 7, and Max leaves it uncapped.

The user manual documents no timer on the control panel or in the app: everything time-based is handled by app schedules.

Control panel lock, set from the app. With it active every button is deactivated and touching one only flashes the indicators blue.

Schedules created in the app turn the purifier on at chosen times, each slot carrying its own fan speed or smart mode, and the power button shows a yellow indicator during a scheduled standby.

IQAir states that the Atem X provides advanced air quality data and usage statistics through the AirVisual app, which also pairs indoor readings with outdoor data from the nearest monitoring station.

IQAir AG is licensed to participate in the AHAM Portable Electric Room Air Cleaners Certification Program, and the October 2023 directory lists the Atem X with certified dust, tobacco smoke and pollen CADR figures and a certified room size of 644 sq ft.

IQAir states Energy Star rated efficiency on the Atem X product page, and the AHAM certified directory of October 2023 marks the model Yes in its Energy Star column. The EPA's current ENERGY STAR certified room air cleaner list holds only IQAir's Atem E.

Purely mechanical filtration with no ionizer and no UV stage, and the AHAM certified directory marks the Atem X as meeting the ozone limits.

The Atem X user manual lists a 2.4 GHz Wi-Fi network as a prerequisite for pairing the purifier with the AirVisual app.

The user manual notes that only some Atem X models carry an Ethernet socket, and neither the US nor the UK specification sheet for this retail model lists one.

IQAir lists the Atem X as Bluetooth enabled with smart app capabilities, alongside Wi-Fi and the AirVisual app.

Touch control panel on the rear rim, with a power button, a smart mode button, a filter warning, a fan speed slider, a light dimming button and a Wi-Fi button, each with its own lit indicator.

The panel is a lit touch surface rather than a graphic display: the manual describes indicators lit white, blue, yellow or red, and a row of dots that counts out the selected fan speed.

IQAir calls it AQGlow. The fan speed slider reverts after about five seconds to showing the current air quality index as a color, readable against the US or Chinese AQI scale.

Three HyperHEPA HF filters, rated by IQAir at 99.5% or better for airborne particles down to 0.003 microns.

The Atem X HyperHEPA Filter Set is particle filtration only, and IQAir offers no activated carbon or gas-phase cartridge for this model. Gas and odor filtration is the job of IQAir's GC series.

Three Impaktor units sit ahead of the HEPA filters and collect large particles, fibers and lint. The manual has them cleaned with a brush or a vacuum, and rinsed under running water when needed.

IQAir rates the three HyperHEPA HF filters at up to 36 months. The filters carry RFID tags, so the purifier tracks each one's remaining life from real pollutant levels and fan speed rather than from a fixed calendar.

IQAir names the AirVisual app and the on-device control panel as the only control methods for the Atem X, and publishes no Google Home integration.

IQAir publishes no Alexa skill for the Atem X: the product page and the user manual list only the AirVisual app and the touch control panel.

The IQAir Cloud custom integration for Home Assistant authenticates against the IQAir account and covers the devices connected to it, exposing the fan and its speed, smart mode, the smart mode profile, the control panel lock and the display light. Its author built it against a GC MultiGas XE, the sibling model already in this catalog.

IQAir claims no Matter support for the Atem X, and a search of the CSA certified products database returns no IQAir entries.

A particulate matter sensor reports live PM2.5 and drives the smart mode's automatic fan speed.

IQAir lists an on-board CO2 sensor, which is unusual on a room air purifier: it reads ventilation rather than filtration.

The integrated sensor set covers PM2.5, CO2, temperature and relative humidity.
