Dyson sells air purifiers that look nothing like the boxy filter units most people picture. The company builds them as bladeless fans on a tall stand, so one machine can sit in a living room, filter the air it draws in, and also move air around like a fan. If you are searching for the best Dyson air purifiers, the real question is which of the current lines suits your room, your season and your tolerance for a premium purchase.
This guide walks through five current models from the Purifier Cool, Hot+Cool and Humidify+Cool families. We explain what separates them, who each one fits, and where a Dyson is probably more machine than you need. We stay with what the maker lists on its product pages and avoid any promise about air quality, because results depend on your home and on how the unit is used.
You will also find a short buying framework, notes on filter replacement, and answers to the questions shoppers ask most often.

How These Options Were Chosen
We built this list from the maker’s own product pages, manual summaries and published specifications. We have not tried these machines ourselves, so nothing here describes a personal experience with them. We limited the field to models Dyson currently lists for the US market and left out older generations that now appear mostly as used or leftover stock. Where a detail matters, such as coverage, noise or filter life, we point you to the listing rather than quote a figure we cannot confirm.
The Best Dyson Air Purifiers You Can Buy Now
Dyson Purifier Cool TP07
The TP07 is the plain, fan-only version of Dyson’s tall purifier family and the usual first stop for anyone new to the brand. It draws air through a combined filter stage, then sends it out through the loop at the top, so you get gentle airflow rather than a visible stream.
It suits a bedroom or a medium living room where you want one quiet-looking appliance instead of a purifier and a separate fan. It connects to the MyDyson app, and a remote clips onto the top of the body, so you can adjust it from the sofa.
The trade-offs are simple. It has no heater, so it does nothing for you in January, and it costs more than conventional filter boxes. Check the listing for the filter type, oscillation range and compatible replacement filter before ordering.
Skip it if you only want filtration at the lowest outlay; a plain tower from another maker will do that for less.
Dyson Purifier Cool Formaldehyde TP09
Think of the TP09 as the TP07 with a longer feature list. Dyson adds a formaldehyde sensor and a catalytic filter layer, and the display reports what the sensors detect. Whether that matters to you depends on your home, so read the maker’s description closely and treat it as a feature, not a promise about results.
It is the sensible step up for someone who likes watching live readouts and wants the machine to adjust itself automatically. Newer homes, freshly furnished rooms and renovation projects are the situations where shoppers tend to ask about this sensor.
The cost is a higher purchase figure and the same fan-only limitation as the TP07. Replacement filters for this generation are a separate part from the TP07’s, so confirm the part number before buying spares.
Skip it if the extra sensing does not interest you; the TP07 shares the same look and basic layout.
Dyson Purifier Hot+Cool HP07
The HP07 answers a common complaint: a purifier that sits idle in winter while a separate space heater does the work. This model combines both jobs in the same tower, with a fan mode for warm weather and a heating mode for cooler rooms.
It fits a study, a nursery-sized bedroom or a living area where floor space is limited and you would rather own one tall appliance than two. Dyson lists a thermostat-style control for the heating side, and the app and remote give you the same adjustments as on the cooler models.
The downside is that you are paying for a heater you may use only part of the year. If your winters are mild, the TP07 may serve you equally well. Electrical load is also worth a thought: follow the manual’s guidance on outlets and extension leads.
Skip it if you already own a heater you like or live where heating is rarely needed.
Dyson Purifier Hot+Cool Formaldehyde HP09
Take the heating tower, add the formaldehyde sensor and catalytic filter set, and you reach the HP09. It is the most complete answer in the Hot+Cool line for someone who wants the screen readouts and a heater in one body.
It makes the most sense in a colder region where the machine will earn its place across several seasons, and where the household appreciates automatic adjustment. A home office or main living room is the natural spot.
It is also among the larger purchases in Dyson’s range, so be honest about how much of that feature set you will use. The heating mode draws real power, so read the electrical notes in the manual and avoid sharing a circuit with other heavy appliances.
Skip it if you want the lower-cost HP07 or just a quiet fan with filtration.
Dyson Purifier Humidify+Cool Formaldehyde PH04
The PH04 is the outlier in the group because it adds humidification. It carries a water tank, and the machine releases moisture into the room as well as filtering and moving air. It targets homes where winter air feels dry and the owner would otherwise buy a separate humidifier.
Because it combines three jobs, it asks more of you. The tank needs filling, and the maker’s instructions for cleaning and descaling should be followed to the letter. If you are not willing to do that routine, a simpler model is wiser.
Check the listing for tank capacity, water type recommendations and the cleaning cycle. Placement matters too: keep it off delicate wood surfaces and away from electronics.
Skip it if your home is already humid, or if you dislike regular water-tank upkeep.
Best for First-Time Dyson Buyers
The Purifier Cool TP07 is the cleanest entry point. It has the signature design, the app, the remote and the combined filter, without the extra sensors, heater or water tank to learn. If you later find you want more, the other lines follow the same basic logic.
Best for Cold Climates
Choose between the Hot+Cool HP07 and HP09. The HP07 is enough if heating is the goal, while the HP09 is the pick if you also want the added sensing. Both replace a separate heater only if the room is modest in size, so read the heater details on the listing.
Best for Dry Winter Air
The Humidify+Cool PH04 is the only model here that adds moisture. It fits a bedroom in a region with long heating seasons, provided you keep up with tank cleaning as the manual directs.
Best for Quiet-Looking Living Spaces
The TP09 is a strong match for a main living room where a screen readout, tidy form and automatic response appeal. The tall bladeless shape fits beside a sofa or shelf and avoids the visual weight of a large filter box.
How to Choose Between Dyson Models
Begin with the season, not the brand. If your main need is filtration plus a fan, the Cool models cover it. If a heater would otherwise be running in the same room, a Hot+Cool model combines the two. If dry air is the concern, only the Humidify+Cool does it.
Next, decide whether you want the formaldehyde sensing. Dyson positions it as an added feature in specific models, and it is the main difference between the TP07 and TP09, and between the HP07 and HP09. Read what each listing says it detects and how the catalytic stage is described, then decide if that justifies the step up.
Think about room size. Dyson does not market these as whole-house machines, and the tower shape is built for one room at a time. Check the listing for the maker’s recommended room size guidance rather than relying on a number from a review, including this one.
Consider ongoing cost. Every Dyson purifier uses a combined filter that needs replacing on a schedule set by the maker, and the part numbers differ by generation. Look up the replacement filter for the model you are considering before you buy, and keep that cost in mind alongside the machine itself.
Finally, weigh the alternatives honestly. Other brands sell conventional towers that filter air at a much lower outlay. A Dyson makes sense when design, the built-in fan, heating or humidifying matter to you. If they do not, a simpler purifier from another line is a reasonable choice.
- Fan and filter only: TP07 or TP09
- Heater included: HP07 or HP09
- Humidifier included: PH04
- Extra sensing: TP09, HP09 or PH04
Setup, Safety and Placement Notes
Follow the manual that comes with the unit. Dyson supplies assembly and placement guidance, and it should override anything you read online. Keep the machine on a flat, stable surface with clear space around the air intake and the loop, and keep cables out of walkways.
For the heating models, do not drape fabric over the unit, and keep curtains, bedding and furniture away from the outlet. Plug it directly into a wall outlet if the manual says so. If your outlet seems loose, scorched or overloaded, have a licensed electrician look at it rather than working around it.
The humidifying model has its own safety rules around water and cleaning. Check local rules about appliances in rental properties if your lease limits portable heaters or humidifiers.
Care and Troubleshooting
Filter replacement follows the maker’s instructions and the prompts on the machine or app. Use genuine or maker-approved filters for the exact model, since the housings differ between generations.
| Symptom | What to check |
|---|---|
| Unit will not power on | Outlet, plug seating, and whether assembly is complete |
| App will not connect | Wi-Fi band, router distance and the app version |
| Filter reminder appears | Order the correct replacement for your model |
| Noisy or uneven airflow | Clear the intake and wipe dust from the loop |
If a fault persists, contact the maker’s support rather than opening the body yourself.
Frequently Asked Questions
Which Dyson air purifier is the best entry point?
The Purifier Cool TP07 is generally the entry point in the current lineup. Check the listing for the latest figure, since Dyson sometimes changes its range.
Do all of these models also work as fans?
Yes, the bladeless design moves air as well as drawing it through the filter. The Hot+Cool models add a heating mode, and the Humidify+Cool adds moisture.
Can I use a Dyson purifier all night in a bedroom?
The makers list night and sleep-style settings on several models. Check the listing for the noise information and for how the display behaves in the dark.
Do I need the app?
No. The remote and on-body controls handle everyday use. The app adds scheduling and live readouts.
Are replacement filters expensive to run?
They are a recurring cost, so look up the replacement part and the maker’s suggested interval for your model before buying.
Is a Dyson better than a standard HEPA tower?
It depends on what you value. A Dyson offers design, a built-in fan and extra functions. A standard tower often costs less to buy and to run.
Bottom Line
For most buyers, the Purifier Cool TP07 is the simplest way into the range, and the TP09 is the upgrade for those who like extra sensing. The Hot+Cool pair makes sense where a heater would be running anyway, and the PH04 is for dry homes with owners who accept tank upkeep. Check each listing for current details and filter parts before you buy.
