7 Best Dyson Vacuums for Asthma Relief in 2025

For asthma and allergy sufferers, the Dyson Purifier Cool PC1 is a breath of fresh air, quite literally. Its standout feature is the fully sealed HEPA H13 filtration system, which doesn’t just have a filter, but seals the entire machine to prevent pollutants from leaking back out. This system masterfully combines activated carbon to tackle bothersome gases and odors with a HEPA layer that captures an impressive 99.97% of microscopic allergens and particles down to 0.3 microns. It’s a powerful ally in maintaining a cleaner indoor environment, directly addressing common triggers like pollen, dust mites, and pet dander.

Beyond just filtering, the Dyson Purifier Cool PC1 leverages Dyson’s signature Air Multiplier technology, projecting over 76 gallons per second of smooth, consistent airflow.
