The market is full of air purifiers that offer ample protection against airborne contaminants but Dyson has made a name for itself thanks to its innovative features and thoughtful devices.

If you’re looking for a Dyson air purifier you might have considered the HP02 and the HP04 largely because they share a lot of Dyson’s proprietary features, but it is the differences that help one take the lead over the other.

So, What is the difference between Dyson HP02 vs HP04?

Dyson HP04 looks more attractive on the spec sheet as it brings almost 360-degree rotation, LCD display, carbon filters, and the ability to throw out air through the back. Whereas, the Dyson HP02’s extra features include Dyson app connectivity but it cuts corners when it comes to the carbon filters and the innovative backflow mode.

While the spec sheet looks painfully similar for both these purifiers, we understand that some features are difficult to understand. This guide will help you understand what each purifier offers in detail, so you can make an informed decision.

Dyson HP02 vs HP04: The Brief Comparison

Dyson air purifiers are specially designed to deal with air pollutants, pet hair, microbial organisms, pollens, allergens, and other impurities that may flare up allergies and both the HP02 and HP04 serve this purpose well.

The Achilles heel for the HP02 is smoke, as the purifier struggles against dense smoke or odors because of the absence of dedicated carbon filters. More on this later here is a brief comparison between these two amazing models:

As you might have noticed that there is a huge difference in power consumption of the two purifiers and both use a very different combination of filters to bring about air purification.

The higher power consumption on the HP04 is not because of efficiency but offers a whole house purification experience. Here are the differences and similarities in detail.

Dyson HP02 vs HP04: The Differences

Let’s start with the differences:

Angle Of Rotation

The Dyson HP02 and HP04 have different angles of rotation. The HP02 rotates at an angle of 180 degrees while the HP04 has an adjustable oscillation angle of 350 degrees which circulates air in the whole room, making use of the additional power that the purifier offers.

Carbon Filters

The HP02 does not have carbon filters while the HP04 model has carbon filters. Carbon filters equip the HP04 with the ability to remove odors, VOCs, and other harmful gases to provide you with clean, safe air.

LCD display

The HP04 has an LCD display that indicates the room temperature, humidity, and air quality while the HP02 does not have this feature so you can only monitor these things through the Dyson link app.

Backward Airflow Mode

The HP02 is not equipped with the backward airflow mode while the Dyson HP04 air purifier is. This allows it to allow air purification for a larger space regardless of whether you want to use the heating feature or not.

Dyson HP02 vs HP04: The Similarities

Here are the top similarities you’ll find in both purifiers.

Both HP02 and HP04 come with bladeless designs which ensure they are safe for houses with kids.
They both come with a remote controller.
Both are wifi equipped and can also be controlled by a Dyson link app.
Both Dyson HP02 and HP04 have a heating and cooling feature.
They both have night-time mode and air multiplying technology.
Both of them feature auto mode that triggers whenever there is a drop in the surrounding air quality.
They both have a sleek tower design that looks very elegant.
Both have Jet focus controls that direct the jet of air in a particular direction.
Both are Alexa-supported. You can easily control them through voice commands.
Both can cater to the needs of large rooms but the HP04 can go a step further and can purify huge halls as well.
