It features a fully sealed HEPA H13-grade system that captures 99.97% of allergens as small as 0.3 microns—on par with much pricier models—while also tackling odors from pets, cooking, and smoke with a dual-layer activated carbon and HEPA filter. Its Air Multiplier technology delivers a strong, smooth airflow of over 76 gallons per second, making it effective at both cooling and circulating clean air in rooms up to 400 sq. ft.

In real-world testing, the PC1 proved highly capable in managing dust and pollen during allergy season, with the MyDyson app providing remote monitoring and scheduling—a rare inclusion at this price point. The magnetized remote is a small but delightful touch, keeping controls tidy and accessible. However, it lacks formaldehyde destruction and doesn’t offer backward airflow mode, meaning you can’t purify without cooling, which may bother users seeking draft-free operation. The fan-only focus also means no heating or humidifying, limiting its year-round usefulness.

Against the TP07, the PC1 sacrifices smart voice control and real-time pollution reporting for a significantly lower entry price, making it ideal for renters or secondary rooms. It’s the best budget-friendly Dyson purifier for those who want proven allergen capture without advanced chemical filtration. While it doesn’t have the bells and whistles of premium models, its core filtration performance and app integration offer excellent value for allergy relief on a budget.

For allergy sufferers who want year-round comfort in a single sleek unit, the Dyson HP1 is a versatile all-in-one solution that heats, cools, and purifies with clinical-grade precision. Its fully sealed HEPA H13 filtration system traps 99.97% of microscopic allergens like pollen, dust, and mold spores, while the activated carbon layer removes gases and odors—critical for multi-season indoor air quality. The Air Multiplier technology ensures even heat distribution in winter and powerful cooling in summer, all while maintaining seamless purification.

In daily use, the HP1 shines in climate transition months, where it can purify and gently heat a room without spreading allergens—a common flaw in traditional heaters. We found it especially effective in bedrooms, where maintaining consistent temperature and air quality improves sleep for allergy-prone users. The MyDyson app enables remote scheduling and air quality tracking, though it lacks CO₂ monitoring found in higher-end models. While powerful, the heating function can slightly increase fan noise, making nighttime operation less silent than dedicated purifiers.
