Quick Summary of dyson hp04 vs hp02

Our winner for this comparison of the dyson hp02 vs hp04 is the Dyson hp04 because;

The Dyson HP04 has a more advanced filtration system.
The Hp04 features a LCD display showing the air quality data and other reports.
The hp04 also has more advanced real-time monitoring of the air quality and includes indoor pollen/allergen levels.
The HP04 has the backward airflow mode which gives the device the ability to turn off the heating and cooling functions.
The hp04 has a carbon filter that filters gasses and odors that are really be troublesome for people sensitive to them.
This purifier also provides one of the best airflow at max settings. This means it cools, heats or purifies the air in the room faster than its counterpart.

The Dyson HP02 is still a perfect choice because it still has decent air flow rate compared to other air purifiers on the market. A winning feature it has is the ability for you to control and schedule heating through the app. This is not possible with the hp04 because the function was removed due to new safety regulations in the US. If you want to control the heating function with HP04, you need to activate it with the provided remote while you can do that with the app on HP02.

Differences in the Dyson hp04 vs hp02

In this section, we show you the differences in the Dyson hp02 vs hp04 and what we think about each feature.

Airflow Rate

The HP02 has an Airflow rate of 53 gallons at maximum setting while the HP04 has airflow rate of 82 gallons at maximum setting. This means the dyson HP04 purifies, heats and cools air at a faster rate than the dyson hp02. Though, for both purifiers, you are able to adjust the airflow from concentrate to dispersed.

Oscillation

The Dyson purifiers in the Pure Hot + Cool category can oscillate and tilt. This Oscillation allows the purifiers to project and circulate purified, cooled or heated air across the room.

The dyson HP04 can oscillate at 350° angle while the dyson HP02 oscillates at 70°. So the hp04 has an adjustable oscillation angle from 45˚ to 350˚ to allow it project purified air around the whole room. The hp04 generally has more air blowing directions and air distribution when compared to the hp02. It also features a backward air flow mode to allow air purification without heating or cooling the air. The HP02 has only front blowing.

The dyson hp04 has the option of setting the oscillation rotation to; no oscillation, 45⁰, 90⁰, 180⁰ and 350⁰. So for any angle smaller than 350⁰, you can rotate the hp04 using the app without having to physically rotate the fan yourself.

Filter

The dyson hp04 has a carbon filter while the hp02 doesn’t have one. The activated carbon filter removes odors and gases from the air. This guarantees that you get odor free purified air.

Though they both have HEPA filters, the HEPA filters are different in make. The hp04 has a glass HEPA media filter type while the hp02 has a 360 glass HEPA filter type. These filters capture 99.97% of fine foreign particles in the air like allergens and pollen.

Data Display

For this feature, the dyson HP04 analyses air quality plus the indoor temperature and filter life which it then displays on a LCD screen. It can also display the indoor humidity levels. The HP02 doesn’t have this LCD display screen so its visual monitoring is limited to the mobile app only. The HP04 offers more data and diversity on pollutants while the HP02 is limited on what data is has to show e.g. does not show data on allergens.

Heater Control

For the Dyson HP04, you can't control the heater from the Dyson Link App because of the US government UL1278 compliancy regulation. The phone app cannot let you adjust the temperature but with remote control you can. While for the Dyson HP02, the heater can be controlled with the app. So with this feature available in HP02, you can schedule heating using the app. This cannot be done with the hp04. Please note that for this hp02 vs hp04 dyson comparison, this feature is actually a deal breaker for some buyers. You might want to keep this in mind as you read on.

Similarities with hp02 vs hp04

Even though devices are created for different purposes, companies still make sure not to stray so far from their core features of that product line. Here, we look at how the dyson pure hot+cool link hp02 vs hp04 comparison intersects.

You can intelligently schedule operations, remotely personalize and control your machine from your device.

As a side note, if you are really keen on making savings, you can actually use this data to find out what causes dips in air quality and take measures to prevent this in the future. By doing this, you can improve air quality by other means and reduce the time taken to filter. Therefore, reducing costs of filter replacement over time.
