Weight and Dimension of Dyson Hp07 vs Hp09:

The Dyson Hp07 and Hp09 air purifiers are both slim, lightweight and designed for easy placement in any room. The Hp07 measures 30”H x 9.8”W x 5.12” L and weighs 12 lbs, while the Hp09 is slightly larger with dimensions of 30″H x 9.8″W x 5.12″L and a weight of 12.6 lb – a slight difference that may be beneficial if you need space to move around the unit or want something more discreet when placed on a countertop or shelf.

For those looking for an air purifier that takes up minimal space but still packs powerful cleaning performance, either model would be great options!

However, the lighter weight and smaller dimensions of the Hp07 make it an ideal choice for those who want to save space and don’t have much room. If you have limited space, the lightweight Hp07 is the best choice for less weight and size.

CARD of Dyson Hp07 vs Hp09:

The Clean Air Delivery Rate (CADR) of an air purifier tells you how effectively it can clean the air in a room. The Dyson Hp07 has a CADR of 81, whereas the Dyson Hp09 has a higher rating of 96. That means that the Hp09 is better at quickly and efficiently cleaning large spaces — up to 650 square feet — while still maintaining low noise levels.

The motor on both models is similarly powerful, so they both deliver similarly fast results, with the difference being that the Hp09 cleans more surface area than its predecessor.For larger areas, such as larger bedrooms or living rooms, we recommend opting for the Dyson Hp09 as it provides superior coverage and CADR ratings.

Noise Level of Dyson Hp07 vs Hp09:

The Dyson HP07 and HP09 air purifiers offer near-silent levels of operation. At its maximum setting, the HP07 produces a noise level of only 62 decibels (dB), while the HP09 produces an even quieter 58 dB.

With their integrated automatic mode, both devices adjust their running speed to ensure sufficient air quality without making a lot of noise. When you need extra peacefulness for sleeping, you can activate sleep mode on either device and reduce the max speed to Level 4 out of 10 as well as dimming the display light.

If you prefer quiet operation over large coverage area, then the Dyson HP09 is definitely your best choice – with its 58 dB at maximum settings it is one of the quietest air purifiers available, perfect for people who want to keep their home environment as tranquil as possible.

Filtration system of Dyson Hp07 vs Hp09:

The Dyson Hp07 and Hp09 air purifiers use different types of filtration systems to help remove dust, pollen, pet dander and other airborne particles from the air. The Hp07 uses a H13 HEPA filter, while the Hp09 uses an H13 HEPA Filter plus a catalytic filter.Dyson Hp07 vs HP09 Filters

  • Pre-Filter
  • H13 HEPA Filter
  • Activated Carbon Filter
  • Catalytic Filter


The Pre-Filter is a type of filter that is designed to capture large dust particles like hair and lint, keeping them from entering the other filters in the system. This helps protect the more delicate filters from getting clogged. The Dyson Hp07 and Hp09 air purifiers both feature pre-filters that can easily be removed and replaced when needed.

H13 HEPA Filter:

A H13 HEPA filter (also known as a sealed HEPA filter) is a type of air filter that uses specialized technology to remove particles from the air. This type of filter is designed to capture and retain airborne particles measuring 0.3 microns or larger in size, such as pollen, dust mites, pet dander, and mold spores.

The H13 HEPA filter has the highest level of efficiency among air filters and is the most effective for capturing these small particles, making it ideal for those who suffer from allergies or asthma.

Catalytic Filter:

The unique feature of the Dyson HP09 air purifier is its catalytic filter. This type of filter uses to continuously destroys formaldehyde. The catalytic filter uses a process called oxidation to break down VOCs, or volatile organic compounds. The filter is made from a combination of titanium dioxide and activated carbon, both of which are efficient at removing formaldehyde from the air. The filter has a life span of up to three months.

Activated Carbon Filter:

The activated carbon filter is a type of filter that utilizes absorbent material to remove gaseous pollutants from the air. It works by trapping these particles in microscopic pores on the surface of the filter, where they remain until they are physically or chemically removed.

The Dyson HP07 and HP09 both feature activated carbon filters made from porous carbon, which makes them highly effective at removing odors, smoke and other VOCs from the air. The filter should be replaced when it begins to lose its effectiveness, which typically occurs after about three months.

The Dyson HP09 air purifier is more effective than the Dyson HP07 due to its catalytic filter. The catalytic filter uses oxidation to break down VOCs and formaldehyde, making it better at removing these pollutants from the air than the H13 HEPA filter found in the HP07.

Heating Capability:

The Dyson HP07 and HP09 air purifiers are both designed to heat a room quickly and efficiently. The main difference between them is the size of area they can heat, with the HP09 being able to heat up to 450 square feet while the HP07 can only reach 376 square feet.

When it comes to heating, both purifiers do an excellent job. They draw in cold air from outside, filter it through their advanced HEPA filters, and then release warm air into your home or office.

This means that you get the benefit of clean air while also heating your space with minimal energy usage. HP09 has a larger capacity, it will provide more consistent and powerful results than its smaller counterpart.

Sensors of Dyson Hp07 vs Hp09:

The Dyson HP07 and HP09 air purifiers both use three types of sensors to monitor the quality of the air in a given space

  • PM 2.5 sensor
  • PM 10 sensor
  • Gas sensor

The Dyson HP 09 has 1 more sensor

  • Solid-state formaldehyde sensor

PM 2.5 & PM 10 Sensors:

First two sensor are PM 2.5 & PM 10 measure the level of Particulate Matter present in the air. The PM 2.5 sensor is designed to detect particles smaller than 0.3µm, while the PM 10 sensor is used to detect particles larger than 0.3µm, such as dust mites and pollen grains. These sensors work together to provide a comprehensive view of the air quality in a given space, allowing the air purifier to adjust its settings to suit your needs.

Gas Sensor:

The gas sensor is used to detect Volatile Organic Compounds (VOCs). These gases can range from simple household cleaners and paint fumes, to more dangerous substances like formaldehyde or carbon monoxide. The gas sensor can identify these compounds and alert you when the level of VOCs reaches an unsafe level.

Formaldehyde Sensor:

The Dyson HP09 has one additional solid-state formaldehyde sensor which helps it distinguish between different types of VOCs and provide even greater accuracy in detecting formaldehyde levels in the air. This extra layer of protection ensures that you have clean and safe air in your home or office at all times.

The sensors in both models are highly sophisticated and give you a comprehensive view of the air quality in your environment, but formaldehyde sensor make Dyson Hp09 superior than Dyson Hp 07 air purifier.
