Key features
The IQAir Atem X features advanced HyperHEPA filtration, capturing 99.5% of ultrafine particles down to 0.003 microns. Its energy-efficient design reduces power consumption with an optimized fan system. The purifier includes smart technology integration, allowing remote monitoring and control via the IQAir AirVisual app. Additionally, it offers automatic adjustment with three smart modes that adapt filtration levels based on real-time air quality data.

3 HyperHEPA filters effectively remove ≥99.5% of all airborne particles
Impactors - Stage 1
The Atem X features three Impaktor units, each equipped with 195 precision-engineered blades. These blades are designed to intercept larger airborne particles such as coarse dust, hair, and fibers before they reach the main HyperHEPA filters. This pre-filtration step helps prevent premature clogging of the primary filters, thereby extending their lifespan and maintaining optimal airflow.
HyperHEPA HF Filters - Stage 2
The HyperHEPA technology has been tested and shown to remove ≥99.5% of all airborne particles, including those particles down in the ultra-fine particle size range (<0.1 µm in diameter). Special laboratories equipped with extremely precise measure equipment (some measuring down to 0.003 µm) verified performance beyond the requirements of HEPA.
Our most energy efficient and quietest room air purifier
Removes allergens, bacteria, viruses, mold spores, harmful dust, smoke, PM2.5, PM10, and other fine and ultrafine particles and particle-bound odors.
Each Atem X is individually tested and certified for ultra-fine particle removal.
Patented architecture allows for slimmer, quieter and more energy-effective air purification.
Calibrated Active Laser Particle Sensor

FAQs
Atem X
What makes the Atem X air purifier a standout choice for both large and small spaces, and how does it ensure ultra-quiet operation?
The Atem X air purifier distinguishes itself as one of the most silent, compact high-performance air purifiers available today, catering to a wide range of spaces from extra large rooms to smaller individual areas. Equipped with 8 adjustable fan speeds, it offers unparalleled flexibility in operation. For expansive spaces, the Atem X boasts the capability to purify up to 1650 sq. ft. (approximately 154 m2) in just 30 minutes when set to the highest fan speed. Conversely, for more intimate spaces such as bedrooms and personal offices up to 330 sq. ft., it can complete two air purification cycles per hour on lower settings, maintaining a whisper-quiet operation level of merely 32 dB(A). This dual capability ensures that the Atem X is a versatile solution for various needs, providing efficient air purification without disrupting the tranquility of your environment.
How does the Atem X air purifier leverage technology to provide an automated, energy-efficient air purification experience, and what unique features enhance user convenience?
The Atem X air purifier is designed with a sophisticated, smart sensor-based operation that elevates the air purification experience through automation and efficiency. It incorporates advanced air quality sensors that continuously monitor the environment for fine dust particles (PM2.5), CO2, temperature, and humidity levels. These sensors enable the Atem X to adjust its fan speed dynamically and the level of purification needed, optimizing energy usage by reducing fan speed when high levels of air cleaning are not necessary. An innovative feature, the AQGlow air quality indicator, emits a soft glow behind the unit to visually communicate the current air quality, with this feedback directly informed by the air purifier's internal sensors. Additionally, understanding the user's preference for minimizing electronic disturbances, the Atem X offers a scheduled Wi-Fi off feature. This allows users to designate a specific time window to disable all radio frequency activity, ensuring a restful environment, with the option to automatically re-enable Wi-Fi connectivity at a chosen time. These features underscore the Atem X's commitment to not only improving air quality but also enhancing user comfort and convenience through intelligent design.
How is the Atem X air purifier designed to effectively purify the air in extra large rooms, and what innovative features does it offer to enhance air distribution and cleaning efficiency?
The Atem X air purifier is expertly engineered for high efficiency in extra large rooms, capable of delivering up to two air cleaning cycles per hour in spaces as large as 1650 sq. ft. (154 m2). It incorporates Flexible Air Rotation (FAR) technology, a cutting-edge feature that ensures clean air is propelled further into the room, thereby improving overall room circulation and the efficiency of air cleaning. This technology plays a crucial role in maintaining a uniformly clean air environment across expansive spaces. Additionally, for even larger areas or to achieve superior air distribution, multiple Atem X units can be synchronized in a Constellation setup. This innovative approach allows for the creation of an optimal air distribution network, ensuring that every corner of a large room benefits from purified air. This makes the Atem X an ideal solution for environments requiring comprehensive air purification coverage with enhanced efficiency.
What level of effectiveness does the Atem X air purifier demonstrate in removing viruses, including those responsible for common respiratory illnesses?
The Atem X air purifier showcases a highly effective capability in neutralizing harmful viruses, evidenced by its independently verified removal rate of 99.99%. This impressive efficiency extends to a range of viruses, including the human coronavirus (HCoV-229E), which is commonly associated with the cold; the influenza A virus (H1N1), responsible for the seasonal flu; and the enterovirus 71 (EV71), which leads to hand, foot, and mouth disease. Such a high level of performance in virus elimination underscores the Atem X's role as a critical tool in maintaining a healthy indoor environment, offering peace of mind and protection against common respiratory illnesses.
How effective is the Atem X air purifier in eliminating bacteria, allergens, and mold spores, according to testing?
The Atem X air purifier demonstrates remarkable effectiveness in the removal of airborne bacteria, allergens, and mold spores, ensuring a healthier indoor environment. Through rigorous testing, it has been shown to eliminate 99.94% of E. coli and 99.92% of white staphylococcus bacteria, both of which can cause significant health issues. Additionally, the Atem X has proven to remove 99.94% of Aspergillus niger, a common fungus responsible for mold growth and a variety of allergic reactions. This high level of efficiency in purifying air from harmful microorganisms positions the Atem X as an essential appliance for maintaining clean, safe, and breathable air, effectively protecting inhabitants from various health risks associated with bacteria, allergens, and mold spores.
