Dyson HPO4 Air Purifier Review: The Air Purifier For All Seasons

Are you getting tired of heaters and fans in & out of the loft? Well, if that’s the case, having an air purifier that can be used all-year-round, in any season, is what you need. What exactly is what the Dyson HP04 Pure Hot + Cool Air Purifier does.

It is currently the only model series from Dyson, which works as an air purifier, a heater, and a fan. This is surely one of the manufacturer’s more expensive models, yet it tends to increase its own overall value when it’s multi-function.

Let us see how this Dyson HP04 Pure Hot + Cool Air Purifier compare to other air purifiers out there. It might just be the right air purifier for you!

Dyson HP04 Pure Hot + Cool Air Purifier: Pros & Cons

The Dyson HP04 Pure Hot + Cool Air Purifier is the latest version of the Dyson Pure Hot + Cool series. Unsurprisingly, the device is so popular. One of the reasons for it is that it can do three jobs even though it’s only one. Even though its price is somewhat high, the upgraded fan power it has is enough reason not to think twice about paying more.

Furthermore, the device’s claim to fame is its purification mechanism. It doesn’t just trap 99.95% allergens like pollens and dust, but also different volatile organic compounds, diesel or petrol fumes, as well as those that stem from flat pack furniture & cleaning products.Dyson HP04 Certified Asthma And Allergy Friendly Air Purifier

Dyson HPO4  Design, Size, Placement

The Dyson HP04 Pure Hot + Cool Air Purifier’s design is just the same as the other compact air purifiers that are part of the Dyson lineup. It has this amazing all-white body with some silver-colored accents –just like an accent trim and its base.

Unlike other oval-shaped air purifiers that take lesser space than the round amp yet cannot move the same amount of air, the Dyson HP04 is more powerful. It’s also taller compared to its predecessors, as it is 30 inches in height. Further, the amp’s diameter may increase to 8 inches, rather than the 6 inches in the past.

What’s more, the device’s LCD is now placed on top of the air intake grill, and it’s overall clean and detailed compared to the previous models. In its new LCD, any information regarding the current indoor air quality and humidity level is displayed.

With its new size, the unit is also much heavier –up to 12.35 lbs. nonetheless, it’s light enough for you to move all-around your home.


How It Works

The Dyson HP04 Pure Hot + Cool Air Purifier breaks down different allergens and contaminants in four (4) buckets. The first two (2) are microscopic particles, PM 2.5 and PM10. The third is Volatile Organic Compounds that are potentially dangerous chemicals like formaldehyde or benzene. And the last is nitrogen oxide or NO2 that may contribute to conditions like asthma.

Moreover, Dyson HP04 features the latest glass HEPA filter. Just like the older Dyson air purifier models, the Dyson HP04 Pure Hot + Cool Air Purifier will utilize one air filter that is doing its task of cleaning the air. It also includes an improved 2-stage air cleaning system.

  • True HEPA Filter –With its glass HEPA filter, Dyson HP04 has the capacity to capture 99.97% of any airborne particles –even those as small as 0.3 microns, including pet dander, bacteria, and pollen.
  • Activated Carbon Filter –With this, the Dyson HP04 can neutralize household odors and gases like benzene, nitrogen dioxide, and formaldehyde.

Also, it has a strong fan power, which may easily clean a room of about 400 sq. ft. using it will leave you with a room free from dust and foul odor, not to mention the different allergens that may harm your health.


Dyson HPO4  Key Features

Dyson HP04 Certified Asthma And Allergy Friendly Air Purifier

The Dyson HP04 Pure Hot + Cool Air Purifier has a lot of amazing features, including the following:

  1. Multi-Functionality

It works as an air purifier, a heater, and a fan. It also features an astounding purification mechanism. It does trap not only 99.95% allergens like pollens and dust but also traps various volatile organic compounds –VOCs, diesel, or petrol fumes.

  1. Multiple Control Methods

It can be controlled via different control methods. You may control the Dyson HP04 air purifier using the following:

  • Remote control
  • Smartphone-based application control through Dyson Home app
  • Voice Control through Google Assistant or Amazon Alexa

It also has a digital screen that displays the current settings of the device. This includes the current air quality and the room temperature so that you may see real-time results.

  1. Auto Mode

When in Automatic or Auto Mode, the Dyson HP04 will use its built-in sensors to automatically detect the current air quality and adjust the settings as necessary. This might include increasing or reducing the fan speed.

  1. Night Mode

When in Night Mode, it can operate at a lower decibel level and dim all the lights & digital screens. This mode is a very useful one, especially when you want to sleep peacefully.

  1. Custom Mode

In this mode, you will adjust the heat settings or fan speed manually using the arrows on its remote control or setting the target temperature. You may also adjust the airflow direction and even the oscillation angle from 0 to 350 degrees.


Dyson HPO4 Noise Level

One great benefit of having the Dyson HP04 Pure Hot + Cool Air Purifier is its super silent operation. Its noise level is measured to be just in the 40-57 decibels range. That is considered ‘silent.’ Unquestionably, this isn’t the best quiet air purifier, yet it sure is a promising one.

Furthermore, the airflow is also smooth, and it is even awarded for its improved sound and quality with the ‘Quiet Mark.’

Having said that, the Dyson HP04 is a great air purifier to use nearly anywhere –be it your office or bedroom.


Dyson HPO4 Clean Air Delivery Rate (CADR)

The Dyson HP04 Pure Hot + Cool Air Purifier promotes 83 gallons per second airflow. That is its air output, including the Coanda effect at a maximum fan speed of 10. We may safely say that on 1 to 5fan speeds, the efficiency of Dyson HP04 is 1 to 5 times.

Nonetheless, what Dyson doesn’t state is its real air intake or CADR. In an estimate, since the maximum airflow of the Dyson HP04 Pure Hot + Cool Air Purifier is at 83 gallons per second, then its CADR is at 665 cfm.


Dyson HPO4 Maintenance & Upkeep

The Dyson HP04 Pure Hot + Cool Air Purifier’s maintenance and upkeep are also quite easy –thanks to its intelligent self-assessing design. Particularly, the device’s filtration system is being monitored by a certain internal system, which may alert you when it’s already time to replace it.

Furthermore, in maintaining its filter, you may also wipe down the body of the Dyson HP04 Pure Hot + Cool Air Purifier to keep everything running in order.


Final Say

Dyson HP04 Certified Asthma And Allergy Friendly Air Purifier

Overall, considering all its specs, performance, and features, the Dyson HP04 Pure Hot + Cool Air Purifier is truly a good air purifier. The major drawback probably about this is that it is quite expensive. Having said that, just like the case with most Dyson products, you will surely get what you pay for.

With it being multi-functional –having the capacity to purify air, cool, and heat, all in one unit, which might be controlled through your smart devices, remote control, or automatic mode is for sure a solid package is truly worth your money.

My name is Ryan. I have had a hard time dealing with my allergies. Happily, I found that an air purifier was effective to ease my allergy symptoms. I spent a lot of time researching the best air purifier. I know how hard it can be to find the suitable one. During the reading period, I also read a lot about humidifiers and dehumidifiers. I learned the mechanisms behind the technologies as well as the manufacturers and organizations within the industry. I now feel convinced that I have built a guide that shows you all you need to know about air purifiers, humidifiers, and dehumidifiers. So I came up with the idea of creating this website.
