Dyson Purifier Cool

The Dyson Purifier Cool combines a bladeless fan with a fully sealed HEPA H13 and activated carbon filtration system, capturing 99.95% of particles as small as 0.1 microns while also cooling the room using Dyson's Air Multiplier technology. A built-in laser particle sensor continuously monitors air quality and automatically adjusts purification intensity, displaying real-time pollutant levels including PM2.5, PM10, VOCs, and NO2 on the LCD screen or the Dyson Link app. Auto mode reacts to changing air quality throughout the day, while Night Mode dims the display and runs at a quieter airflow setting for undisturbed sleep, and the bladeless design is safer around children and pets than traditional fan blades.

Frequently asked questions

What is the difference between a HEPA filter and an activated carbon filter in an Air Purifier?

A HEPA filter captures 99.97% of particles as small as 0.3 microns, including dust, pollen, and bacteria. An activated carbon filter, on the other hand, is designed to capture gases, odors, and chemicals. Some Air Purifiers combine both filters for comprehensive air cleaning.

How often should I replace the filter in my Air Purifier?

The frequency of filter replacement depends on the model and usage. Typically, filters need to be replaced every 6-12 months. Check your Air Purifier's manual for specific guidelines, and consider models with washable filters for cost-effective maintenance.

Can an Air Purifier help with pet allergies?

Yes, an Air Purifier can help alleviate pet allergies by removing pet dander, hair, and odors from the air. Look for models with HEPA filters and high CADR ratings for effective pet allergen removal.

Are Air Purifiers noisy?

Some Air Purifiers can be noisy, especially when operating at high fan speeds. However, many modern models are designed to be quiet, with noise levels as low as 20 decibels. Look for models with silent or whisper-quiet operation if noise is a concern.
