Overview of Coway Air Purifiers
Coway air purifiers feature a distinctive slim, oval tower design. Inside each model is a 4-stage filtration system:
- Pre-filter – Catches large particles like hair and dust
- Carbon filter – Removes odors and volatile organic compounds (VOCs)
- True HEPA filter – Traps 99.97% of particles 0.3 microns, including pollen, mold, bacteria
- Vital Ion – Charges particles to enhance filtration
The combination of HEPA and activated carbon gives Coway air purifiers strong performance for removing both particles and odors.
Coway’s air purifiers cover rooms up to 361 square feet, with Clean Air Delivery Rates (CADR) ranging from 233 – 303 cubic meters per hour. This measures the unit’s effectiveness at removing dust, pollen, and smoke. The higher the CADR, the faster it can clean the air.
One handy feature is the air quality indicator, which displays the real-time air quality and changes color based on pollution levels. Coway models also have filter change indicators to alert you when it’s time to replace filters.
Operating noise ranges from 24.4 decibels on the lowest setting up to 53.8 dB on the highest setting. For comparison, 30 dB is a quiet library and 60 dB is normal conversation. So Coway purifiers run very quietly.
Coway air purifiers range in price from about $100 to $400 depending on the model and coverage size. The company provides a 3 year limited warranty. Overall Coway offers affordable, efficient, and smart air purifiers.
Overview of Dyson Air Purifiers
Dyson air purifiers feature a distinctive round, futuristic tower design. The main filtration is provided by HEPA filters that capture 99.97% of allergens and pollutants as small as 0.3 microns.
Models also include activated carbon filters to help remove household odors and some VOCs. However, Coway includes larger carbon filters for enhanced odor reduction.
Dyson air purifiers have Clean Air Delivery Rates up to 240 m3/hr, covering rooms up to 248 square feet effectively. So the performance is similar to Coway, though some Coway models provide greater coverage and airflow.
Dyson purifiers operate at noise levels up to 64 dB on the highest fan setting. That’s noticeably louder than Coway models which can run as low as 24 dB.
Smart features are lacking on Dyson air purifiers. They do not have air quality monitors or filter change alerts. You need to manually check the filters and replace them about once a year.
Dyson air purifiers range from $400 to $650, making them significantly more expensive than comparable Coway models. Dyson provides a 2 year limited warranty on parts.
