Filtration Technology

The TP04 uses a sealed True HEPA filter combined with an activated carbon layer to capture 99.97% of particles as small as 0.3 microns , including pollen, dust mites, mold spores, and fine pet dander. The carbon filter absorbs VOCs, gases, household odors, and smoke.

Compared to many competitors that use basic HEPA-type filters, Dyson's sealed filtration system is designed to prevent air from bypassing the filter entirely, which is a meaningful advantage for allergy sufferers.

CADR & Sound

Noise & Performance

Dyson doesn't publish traditional CADR ratings, which makes direct comparisons difficult, but the TP04 is rated for whole-room coverage using Dyson's proprietary Air Multiplier technology with 350-degree oscillation. At lower speeds the unit runs relatively quietly, though customer feedback is mixed , some find it perfectly fine for bedroom use while others note the airflow noise is more pronounced than dedicated whisper-quiet purifiers.

At higher speeds, expect noticeable fan noise typical of a tower fan.

Connectivity

Smart Features & Controls

This is where the TP04 shines. It connects via WiFi to the Dyson Link app, giving you remote control, scheduling, real-time air quality graphs, and filter life tracking from your phone.

Auto mode uses built-in sensors to detect pollutants and automatically adjust fan speed to match current air quality levels. It also includes a magnetic remote control that docks on top of the unit, night mode for dimmed display, and a sleep timer , a genuinely complete smart feature set.

Upkeep

Filter Maintenance

Dyson recommends replacing the HEPA and carbon filter approximately every 12 months depending on usage, and the app tracks filter life so you know exactly when a change is due. There's no washable pre-filter , the sealed unit is designed to be replaced as a single combined filter.

Replacement filters are available under Dyson's own part numbers and tend to cost more than third-party HEPA filters, though aftermarket options exist.

Who Is This Air Purifier For?

Ideal For

  • Allergy and asthma sufferers who need certified True HEPA filtration that auto-adjusts when pollen or dust levels rise
  • Pet owners dealing with dander and odors , the carbon filter neutralizes pet smells while HEPA captures fine dander particles
  • Smart home enthusiasts who want app-based scheduling, remote monitoring, and real-time air quality data on their phone
  • Anyone who wants a purifier and fan in one device to save space and get year-round use

Not Ideal For

  • practical buyers , even refurbished, the TP04 sits at a premium tier with premium replacement filters
  • Light sleepers who need near-silent operation , the fan-based design can produce noticeable airflow noise at lower speeds
  • Users who just need basic purification without smart features , simpler, entry-level HEPA purifiers deliver similar filtration

Setup is straightforward , remove the filter covers on the base, snap in the sealed HEPA/carbon filter, attach the tower loop to the base, and plug in. WiFi pairing through the Dyson Link app takes a few minutes and walks you through connecting to your network.

Run the purifier on a high setting for the first hour to clear any initial manufacturing odors from the new filter

Position at least 6 inches from walls to allow unobstructed 350-degree airflow and accurate sensor readings

As a refurbished unit, warranty coverage is typically shorter than Dyson's standard 2-year warranty for new products. Verify the specific warranty terms with the seller at the time of purchase, as refurbished warranty policies vary by retailer and refurbisher.

FAQ

Does the Dyson TP04 actually remove allergens and pet dander effectively?

Yes. The True HEPA filter captures 99.97% of particles at 0.3 microns, which includes common allergens like pollen, dust mite debris, mold spores, and pet dander.

The auto mode senses pollutants and ramps up when air quality levels drop, so it responds automatically during high-allergen periods.

How loud is the Dyson TP04 Pure Cool at night?

Customer feedback is mixed on noise. At the lowest speed and in night mode (which dims the display and limits airflow), it's reasonably quiet for most sleepers.

However, some light sleepers report it's still noticeable compared to purifiers without a fan function. If silent operation is critical, test it at the lowest setting before committing to bedroom use.

What does the Dyson TP04 app actually let you control?

The Dyson Link app provides full remote control including fan speed, oscillation, auto mode, and scheduling. It also displays real-time air quality data with graphs showing particulate matter, VOC levels, and pollutants over time.

You can monitor filter life and receive replacement reminders directly in the app.

How often do I need to replace the filter and how much does it investment?

Dyson recommends filter replacement roughly every 12 months with regular use. The app tracks filter life so you won't have to guess.

Official Dyson replacement filters typically run though compatible third-party filters are available at lower tier. There's no washable pre-filter , the sealed HEPA and carbon filter unit is replaced as one piece.

Is a refurbished Dyson TP04 worth buying over a new one?

Refurbished units offer significant savings on a premium product that retails at a high tier new. The core filtration performance is identical , you get the same True HEPA filter system, smart features, and app connectivity.

The trade-offs are potential cosmetic imperfections and a shorter warranty, so verify the return policy and warranty terms before purchasing.

Can the Dyson TP04 help with smoke and cooking odors?

Yes. The activated carbon filter is specifically designed to absorb gases, VOCs, smoke particles, and cooking odors, while the HEPA filter captures fine smoke particulates.

Auto mode will detect the rise in pollutants from cooking or nearby smoke and increase fan speed automatically to clear the air faster.
