The Dyson Purifier Cool PC1 (model TP11) is the model Dyson now sells in place of the Purifier Cool TP07, which Amazon US carries only through third-party sellers. It is a purifier and a bladeless fan in one tower: a sealed filter of glass HEPA and activated carbon, 350° oscillation, ten speeds, and an app that reports air quality.
Our verdict: buy it if you want a fan for summer and like Dyson's design, not if clean air per dollar is the goal. Dyson does not publish a clean air delivery rate, and no Dyson model is in the AHAM Verifide directory, so there is no certified way to compare its purifying power with a Blueair 211i Max or Levoit Core 400S-P that cost less.
Dyson PC1 vs TP07: what changed
The TP07 (Purifier Cool, 2021) and the PC1 share the same idea: a loop-shaped tower that pulls air through a cylindrical HEPA and carbon filter in the base and pushes it out as a fan stream. Both appear on the California Air Resources Board's list as mechanical air cleaners, the TP07 under certification G-22-187 and the TP11 under G-24-288. Dyson's current US range lists the PC1, while the TP07 is available on Amazon only from third-party sellers at higher prices, so the PC1 is the model to buy new.
Dyson describes the PC1's filter system as fully sealed, with the whole machine sealed to HEPA H13 grade, meaning air should not bypass the filter through gaps in the body. It lists 350° oscillation, ten fan speeds, a magnetic remote, and app control through MyDyson with schedules and air quality reports.
The CADR problem
Every other purifier we review is compared on clean air delivery rate, the cubic feet of filtered air per minute measured by AHAM's standard test. Dyson does not publish one. When we searched the AHAM Verifide directory on November 3, 2026, it listed no Dyson models. Dyson instead describes its own whole-room tests run in Auto mode and states that its machines capture 99.97% of particles down to 0.3 microns, which describes the filter, not how fast the machine cleans a room.
Dyson's listing quotes "over 76 gallons per second" of airflow, about 610 cubic feet per minute, but that is the fan stream it projects, mostly room air entrained around the loop, not filtered air. It cannot be compared with a CADR. Without a certified figure we cannot tell you what size room the PC1 cleans properly; for anything over a large bedroom, an AHAM-listed purifier is the surer bet on paper. Our CADR guide explains why this number matters.
Filter and running cost
The PC1 takes Dyson's 360 Combi Glass HEPA + Carbon filter, part 965432-01, which Dyson's parts page lists at $79.99. Dyson recommends replacing it every 12 months or when the machine and app say so. That is a reasonable yearly cost, similar to a Blueair or Levoit mid-size filter.
| Item | Cost |
|---|---|
| Filters, one a year for 3 years | $239.97 |
What you get for the money
- A real fan. In summer the PC1 doubles as a cooling fan, which no ordinary purifier does well. If you would buy a tower fan anyway, part of the price is the fan.
- Sealing and build. A fully sealed machine means the filter's rating is not undone by leaks around it.
- Air quality reporting. The app and display report air quality; that is useful but not a substitute for a dedicated air quality monitor.
- Odor control. Dyson claims the carbon layer captures 97% of odors such as cooking smells and smoke, a claim based on Dyson's own testing.
Dyson PC1 vs the alternatives
| Model | Smoke CADR | Room size | Also a fan? |
|---|---|---|---|
| Dyson Purifier Cool PC1 | Not published | Not published | Yes |
| Blueair Blue Pure 211i Max | 435 cfm | 674 sq ft | No |
| Levoit Core 400S-P | 234 cfm | 363 sq ft | No |

Who should buy the Dyson Purifier Cool PC1
- Buy it if you want one machine to cool a bedroom or office in summer and filter it all year, and you value Dyson's design and app.
- Buy it to replace a TP07: same concept, current model, same yearly filter cadence.
- Skip it if you want the most clean air per dollar; AHAM-listed purifiers give certified airflow for less.
- Skip it for wildfire smoke or a large open plan room, where a high certified CADR is what you need. See our wildfire smoke picks.
- Need heat as well? See the Dyson Purifier Hot+Cool HP1.
Frequently asked questions
Is the Dyson PC1 the same as the TP07?
No, but it is the model Dyson now sells in its place. Both are bladeless purifier fans with a HEPA and carbon filter; the PC1 is model TP11. Amazon US now carries the TP07 only from third-party sellers.
What is the CADR of the Dyson Purifier Cool PC1?
Dyson does not publish one, and no Dyson model was in AHAM's Verifide directory when we checked on November 3, 2026. Dyson's 76 gallons per second airflow figure describes the fan stream, not filtered air.
How often do you replace the Dyson PC1 filter?
Dyson recommends every 12 months or when the machine notifies you. The 360 Combi Glass HEPA + Carbon filter, part 965432-01, is listed at $79.99 on Dyson's parts page.
Does the Dyson Purifier Cool PC1 produce ozone?
California lists the TP11 as a mechanical air cleaner, meaning it filters without an ionizer or other electronic stage. Mechanical purifiers are not an ozone source.
Is a Dyson worth it compared with a regular air purifier?
Only if you will use the fan. For purifying alone, AHAM-listed purifiers such as the Blueair Blue Pure 211i Max (435 cfm smoke CADR) deliver certified airflow for less money.
What size room can the Dyson PC1 clean?
Dyson does not give a square-footage rating; it describes whole-room tests run in Auto mode. Without a CADR, we would use it in a bedroom or office rather than a large open plan room.
