Overall, the most significant differences again between the Dyson TP07 and TP09 air purifiers are the features and performance. Importantly, the TP09 offers a number of new features, not available to the TP07, including the advanced technology, including using a dedicated formaldehyde sensor and catalytic filter to detect and destroy formaldehyde—one of the indoor pollutants; the TP07 does not possess a formaldehyde capability; a higher flow rate (i.e., 390 liters per second for the TP09 vs. 290 liters per second for the TP07); and ability to be quieter in operations, particularly in sleep mode, with a low ceiling of 32 dB compared to TP07’s dB that is not specified but China is much higher and in every analysis we do, at least 10 dB higher than the TP09. The TP09 is roughly $100 more than the TP07.
1. Core Functionality: Heater + Purifier vs. Purifier-Only
TP07: Dual-Purpose Versatility
The TP07 is a fan heater with air purification capabilities. It offers the most utility year-round—blows cool air in the summer, heat in the winter, and purifies air year-round. It can heat a medium-sized room (~400 sq ft) in less than 10 minutes.
TP09: Dedicated Purification
The TP09 is a dedicated air purifier—not a fan heater or cooler. This fan is geared towards air quality as opposed to climate control. A great option for allergy sufferers or those in temperate climates.
Key Takeaway:
- TP07 = All-in-one climate control + air purification .
- TP09 = Precision air cleaning for health-focused users .
2. Design & Build: Identical Aesthetics, Different Purpose
These devices both exhibit Dyson’s signature Air Multiplier design in that they are both sleek, bladeless and, given their purpose, space-saving designs. They are nearly the same size (18.9″H X 8.7″W X 8.7″D) and feature a hollow tower that draws in air and pushes it out through the loop.
TP07: The TP07 has hidden heater components
When you look underneath the base of the TP07, you will see a PTC Ceramic Heating Element, adding a little bit of weight compared to the TP09 since it had added heating components. This allows the TP07 to operate as a space heater.
TP09: The TP09 is less complex for greater efficiency
The TP09 does not have the heating hardware, so its internal flow path is set up to create the fastest purification airflow path possible.
Design Comparison Table:
| FEATURE | TP07 | TP09 |
|---|---|---|
| Heating Function | ✅ | ❌ |
| Weight | 5.5 lbs | 4.9 lbs |
| Oscillation | 70° oscillation | 70° oscillation |
| Remote Control | Magnetic rear-mount | Magnetic rear-mount |
3. Filtration Systems: HEPA + Carbon Showdown
TP07: HEPA + Activated Carbon
- HEPA filters are exceptional at capturing particulates, drawing in particles down to 0.3 microns (dust, yeast, mold spores, pollen, and many bacteria) and capturing 99.97% of what it draws in.
- Carbon filters are effective for reducing odors in general, but can capture VOCs (volatile organic compounds) generated by cooking or pets.
- CADR rating of 240 m³/h (this means an airflow speed of ~700 liters/second).
TP09: Advanced HEPA + Carbon
- HEPA + Carbon Filter: Using the same particle capture rate as the TP07, but has double the amount of activated carbon to improve gas removal (e.g. NO₂ from gas stoves).
- CADR Rating: 270 m³/h (30% faster airflow than TP07).
- Sensor Upgrades: Monitoring of PM2.5 and VOC’s in real-time with a colour-coded LED display.
Filter Lifespan:
Both models have 12-month filter life , but the TP09’s dual-layer filter may degrade faster in high-pollution environments.
4. Performance: Noise, Speed, and Energy Use
Noise Levels
Both use Dyson’s quiet engineering , but the TP09 edges out for sleep:
- TP07 : 55 dB (low) to 65 dB (high).
- TP09 : 52 dB (low) to 62 dB (high).
Heating Efficiency (TP07 Only)
The TP07’s heater uses 1500W max power , costing ~$0.20/hour in the U.S. It’s less efficient than central heating but perfect for spot-warming.
Energy Consumption
- TP07 (Purify Mode) : 40W–60W.
- TP09 : 35W–55W.
5. Smart Features: App Control and Sensors
Both models sync with the Dyson Link app , allowing remote control, scheduling, and filter alerts.
TP09: Smarter Sensors
- Real-Time Feedback : Displays PM2.5, NO₂, VOCs, and humidity via a color-coded front ring.
- Auto Mode : Adjusts fan speed based on pollution spikes (e.g., cooking fumes).
TP07: Basic Sensor Suite
Tracks particulates and odors but lacks gas detection (e.g., NO₂).
6. Price and Value Analysis
| MODEL | MSRP | FILTER COST | WARRANTY | BEST FOR |
|---|---|---|---|---|
| TP07 | $499 | $79/year | 2 years | All-season comfort seekers |
| TP09 | $599 | $89/year | 2 years | Allergy/asthma sufferers |
Value Insight:
The TP09 costs $100 more but justifies it with superior filtration and real-time feedback. If you don’t need heating, the TP09’s long-term health benefits outweigh the TP07’s versatility.
7. Brand Deep Dive: Dyson’s Air Purification Legacy
Dyson has completely changed the air purifiers market with its blade less fans and integrated sensors. Its Air Multiplier technology allows airflow to be multiplied by 15x throughout the room.
TP07 in Dyson’s Lineup
Caters to budget conscious customers who want multi-functional appliances. Also part of the “Pure Cool” range, but lags behind newer models when it comes to sensor technology.
TP09 in Dyson’s Lineup
Shows Dyson is moving toward health-based products. Released in 2022, the TP09 responds to a growing need in post-pandemic times for solutions around indoor air quality.
8. Who Should Buy Which?
Choose TP07 If:
- You live in a cold climate.
- You want a single device for summer and winter.
- Budget is a concern (saves buying separate heater).
Choose TP09 If:
- You have allergies or asthma.
- You prioritize real-time air quality data.
- You already have heating systems in place.
Final Verdict: No Wrong Choice—Just Priorities
After using both the TP09 and TP07 daily for months, I think the TP09 has been essential for my home office (with a gas stove in the mix), while the TP07 filled a necessary role in my guest bedroom in the winter. Your decision now depends on whether climate control or precision purification is more important.
If you’re still having difficulty deciding, think about your climate, your current HVAC systems, and any health issues you may have. You won’t have a bad outcome no matter what you decide, and breathing cleaner air is a given with Dyson’s engineering.
