- Built-in air quality monitor shows real-time particle levels
- Whisper-quiet operation from 22 dB to 68 dB
- Multiple fan speeds and timer settings
- App control via smartphone
The housing has a squared-off, boxy design with a Swiss industrial aesthetic. The controls are fairly simple to use directly on the unit. IQAir systems range from $799 for a small room purifier up to $899 for a large 1,125 sq ft purifier. The filters need replacing every 4-5 years.
Overview of Dyson
Dyson air purifiers utilize HEPA filtration to capture 99.95% of particles down to 0.1 microns. This includes most pollutants like dust, mold, pet dander and smoke. Key features include:
- Coverage for rooms up to 800 sq ft
- Uses Air Multiplier technology for higher airflow
- Very quiet operation from 4 dB to 77 dB
- Real-time air quality monitoring with LCD display
- Sleek and modern design
- App control, Alexa and Siri voice control
- Tower shape maximizes filtration
- No replacement filters needed
Dyson air purifiers have a signature sleek, futuristic design. The HEPA filter is fully sealed within the tower-shaped housing. Controls are located at the base, with an LCD screen displaying current air quality. Models range from $449 for small rooms up to $699 for large rooms. A key advantage is the filters never need replacing – just occasional washing.

Key Differences Between IQAir and Dyson
Up until this point, we’ve covered the fundamental information. Now, let’s analyze and contrast them based on their crucial characteristics.
· Filtration Technology
The biggest difference between IQAir and Dyson is the filtration technology used. IQAir uses a HyperHEPA filter that can remove particles down to 0.003 microns with 99.5% efficiency. This includes ultrafine particles and allergens.
In contrast, Dyson uses a standard HEPA filter that captures particles down to 0.1 microns at 99.95% efficiency. While effective for most pollutants, it may not catch the smallest nanoparticles. Those with allergies or sensitivities may benefit more from IQAir’s HyperHEPA filtration.
Both brands have tightly sealed filters that prevent leakage, ensuring all air passes through the filter medium. IQAir’s modular design also lets you add components like gas/VOC filters for a more comprehensive clean.
· Room Coverage
For room coverage, Dyson air purifiers are rated for spaces up to 800 sq ft which is suitable for large living rooms and open floor plans.
IQAir systems can cover 322 to 1,125 sq ft depending on the model. The larger options can easily purify extra-large rooms over 1,000 sq ft. Those with big indoor areas to clean may prefer IQAir’s greater room capacity.
· Noise Level
In terms of noise, both IQAir and Dyson run at very low decibel levels so they won’t disturb you. Dyson purifiers operate from near-silent 4 dB on the lowest setting up to 77 dB on max.
IQAir has a comparable range from 22 dB to 68 dB depending on fan speed. Both brands allow adjusting the fan to minimize noise as needed. At lower speeds, they are extremely quiet and can even run while sleeping.
· Air Quality Sensors
Both IQAir and Dyson systems have built-in air quality sensors and particulate monitors. They display real-time readings showing PM2.5 levels, VOCs, allergens and other data.
You can see at a glance if indoor pollution is high, and adjust the fan speed accordingly. The sensors also detect when air is cleaner and automatically decrease the speed. This monitoring allows the purifiers to respond intelligently to conditions in the room.
· App Control
The IQAir and Dyson apps allow controlling the purifier remotely via smartphone. You can change speeds, set schedules, monitor air quality, and more. This allows turning on the purifier even when away from home to start cleaning the air before you get back.
Both apps are user-friendly with intuitive interfaces. Dyson also supports Alexa voice controls through compatible devices. The connectivity options make it simple to control these high-tech purifiers.

· Design
In terms of design, IQAir units have a squared-off, boxy shape with a Swiss industrial look. The controls are fairly basic and located on the device itself.
Dyson purifiers feature a sleek, modern tower design. The HEPA filter is built into the hollow center of the tower for smooth, efficient airflow. The LCD display and controls give it a high-tech minimalist aesthetic.
It’s mainly an issue of personal taste – IQAir aims for function over form, while Dyson has a striking contemporary style.
