The most important differences between the Dyson TP07 and TP09 air purifiers lie in their features and performance. The TP09 includes advanced technology to detect and destroy formaldehyde—a common indoor pollutant—using a dedicated sensor and catalytic filter, while the TP07 lacks this capability. Additionally, the TP09 offers a higher airflow rate (390 liters per second vs. 290 liters per second) and operates more quietly, especially in sleep mode (as low as 32 dB compared to the TP07’s unspecified but likely higher level), though it comes at a higher price point, typically around $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 . It’s ideal if you want year-round utility: blow cool air in summer, heat in winter, and clean air all year. Its heating function is powerful enough to warm a medium-sized room (~400 sq ft) in under 10 minutes.
TP09: Laser-Focused Purification
The TP09 is a dedicated air purifier —no heating or cooling. It prioritizes air quality over climate control, making it perfect for allergy sufferers or those in consistently 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
Both models share Dyson’s signature Air Multiplier design—sleek, bladeless, and space-saving. They’re nearly identical in size (18.9” H x 8.7” W x 8.7”), with a hollow tower that draws in air and expels it through the loop.
TP07: Hidden Heater Components
Inside the TP07’s base, you’ll find a PTC ceramic heating element , adding slight heft compared to the TP09. This component allows it to function as a space heater.
TP09: Streamlined for Efficiency
The TP09 lacks heating hardware, so its internal airflow path is optimized for purification speed.
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 Filter : Captures 99.97% of particles down to 0.3 microns (dust, pollen, mold).
- Carbon Filter : Reduces odors and volatile organic compounds (VOCs) from cooking or pets.
- CADR Rating : 240 m³/h (airflow speed: ~700 liters/second).
TP09: Advanced HEPA + Carbon
- HEPA+Carbon Filter : Same particle capture as TP07 but with double the activated carbon for enhanced gas removal (e.g., NO₂ from gas stoves).
- CADR Rating : 270 m³/h (30% faster airflow than TP07).
- Sensor Upgrades : Real-time PM2.5 and VOC monitoring with color-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 revolutionized air purifiers with bladeless fans and integrated sensors . Their Air Multiplier tech amplifies airflow by 15x, ensuring even distribution.
TP07 in Dyson’s Lineup
Targets budget-conscious buyers wanting multi-functional appliances . It’s part of the “Pure Cool” series but lags behind newer models in sensor tech.
TP09 in Dyson’s Lineup
Represents Dyson’s push into health-centric appliances . Released in 2022, it aligns with growing demand for indoor air quality solutions post-pandemic.
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
Having used both daily for months, I’ve found the TP09 indispensable in my home office (gas stove nearby), while the TP07 shines in my guest bedroom during winter. Your choice hinges on whether you value climate control or precision purification more.
If you’re still torn, consider your local climate, existing HVAC systems, and health needs. Either way, Dyson’s engineering ensures you’re breathing cleaner air.
