Filtration Technology
The PC1 uses a 2-stage filtration system starting with an H13 HEPA filter , medical-grade filtration that captures 99.95% of particles as small as 0.3 microns, including pollen, dust mites, mold spores, and fine smoke particles. The second stage is an activated carbon filter designed to absorb household gases, VOCs, odors, and cooking smells.
While many entry-level purifiers use basic HEPA or HEPA-type filters, the H13 grade here matches what you'd find in hospital-grade units, and the carbon filter adds meaningful odor and gas protection that HEPA alone cannot provide.
Noise & Performance
The Dyson PC1 covers 101 sq ft, which positions it firmly in the small-room category , suitable for a home office, nursery, or small bedroom but not for open living areas. The measured noise level of 61.4 dB is roughly equivalent to normal conversation volume, which is notably louder than many competitors that achieve 25-35 dB at their lowest fan speeds.
For bedroom use, this noise level may serve as white noise for some sleepers but could be intrusive for those who prefer silence.
Smart Features & Controls
This is where the PC1 punches above its size class. It includes WiFi connectivity with the dedicated Dyson app for remote monitoring, scheduling, and air quality tracking , a feature found in only about 13% of purifiers on the market.
Voice assistant compatibility lets you control the unit hands-free through Alexa or Google Assistant, and the included remote adds convenience for quick adjustments. The built-in air quality indicator provides real-time feedback, though the notable absence of an auto mode means you'll need to manually adjust fan speeds even when air quality changes.
Filter Maintenance
Dyson typically recommends filter replacement every 12 months with average use, though actual life depends on usage hours and local air quality. The unit features a filter change indicator to alert you when replacement is due, removing the guesswork from maintenance scheduling.
Filter installation is designed to be tool-free and straightforward, consistent with Dyson's user-friendly approach , check Dyson's website or app for the specific replacement filter model number for this unit.
Who Is This Air Purifier For?
Ideal For
- ✓ Small-space dwellers and apartment residents who need targeted filtration in rooms under 100 sq ft like home offices, nurseries, or studio corners
- ✓ Smart home enthusiasts who want WiFi-connected air quality monitoring, app scheduling, and voice control through Alexa or Google Assistant
- ✓ Allergy and asthma sufferers in small rooms who need H13-grade HEPA filtration to capture 99.95% of pollen, dust mites, and pet dander
- ✓ Pet owners in compact spaces who need both the HEPA filter for dander and the carbon filter to neutralize pet odors and gases
Not Ideal For
- ✕ Large room or whole-house users , at 101 sq ft coverage, this purifier is insufficient for living rooms, open floor plans, or any space over 10x10 feet
- ✕ Light sleepers who need whisper-quiet overnight operation , the 61.4 dB noise level is louder than most competing bedroom purifiers at their lowest setting
- ✕ Set-it-and-forget-it users who want auto mode to automatically respond to changing air quality without manual fan speed adjustments
Setup is minimal , remove the outer shell, insert the sealed HEPA and carbon filter unit, snap the housing back into place, and plug in. WiFi pairing through the Dyson app typically takes under five minutes and unlocks remote control, scheduling, and air quality history.
Run the purifier on high for the first 30-60 minutes to clear any initial manufacturing odors and circulate air through the new filter
Place the unit at least 12 inches from walls to ensure unobstructed airflow for optimal filtration performance
Dyson typically offers a 2-year warranty on their air purifier products covering defects in materials and workmanship, with support available through the Dyson app, website, or phone. Verify specific warranty terms for the PC1 model directly with Dyson, as coverage details may vary by region and retailer.
FAQ
What size room can the Dyson Purifier Cool PC1 cover?
The PC1 is rated for 101 sq ft, which is roughly a 10x10 foot room. This makes it ideal for small bedrooms, home offices, nurseries, or dorm rooms.
For larger spaces, you'd need to step up to a higher-capacity Dyson model or use multiple units.
Does the Dyson PC1 remove odors and smoke smell?
Yes, the 2-stage filtration system includes an activated carbon filter specifically designed to absorb odors, smoke, cooking smells, VOCs, and other gases. The H13 HEPA filter also captures fine smoke particles.
Customers generally report good results with odor reduction, though heavy smoke may require a unit with a larger carbon filter capacity.
How loud is the Dyson Purifier Cool PC1?
The PC1 measures at 61.4 dB, which is similar to the volume of a normal conversation or a running dishwasher. While some customers describe the operation as quiet relative to its airflow, others note it's louder than expected.
For context, many competing purifiers achieve 25-35 dB at their lowest speed setting.
Can I control the Dyson PC1 with Alexa or Google Assistant?
Yes, the PC1 supports voice assistant control through both Alexa and Google Assistant when connected via WiFi. You can also control it through the Dyson app on your smartphone, which provides additional features like air quality monitoring, scheduling, and filter life tracking.
A physical remote is also included.
Does the Dyson PC1 have an auto mode that adjusts fan speed automatically?
No, the PC1 does not include an auto mode despite having a built-in air quality indicator. You'll need to manually adjust the fan speed based on the air quality readings.
This is a notable omission compared to many competing purifiers in this category that offer automatic speed adjustment.
How often do you need to replace the filter on the Dyson PC1?
Dyson generally recommends replacing filters every 12 months under typical use conditions, though this varies based on daily runtime hours and local air quality. The PC1 includes a filter change indicator that notifies you when it's time for a replacement, so you won't have to guess or track it manually.

Bottom Line
The Dyson Purifier Cool PC1 is a premium small-room air purifier that delivers genuine H13 HEPA filtration and best-in-class smart connectivity in a compact, well-designed package. It's the right choice if you want Dyson build quality, app-based monitoring, and medical-grade filtration for a space under 100 sq ft. However, the limited coverage area, absence of auto mode, and higher-than-average noise level mean practical buyers or those with larger rooms should explore alternatives.
Best for smart home users who want premium H13 HEPA filtration with full app and voice control in a small room or personal space
Consider alternatives if you need coverage beyond 101 sq ft, require whisper-quiet operation for sleeping, or want auto mode to adjust fan speed based on air quality
