Suitable Room Size of Dyson dp04 air purifier

The Dyson DP04 is a tower-style air purifier that’s designed for use in medium to large rooms. It has a CADR rating of 280, which means it can filter out up to 280 cubic feet of air per minute.

This is a very high rate and can easily filter the air in a large room within minutes.

The Dyson DP04 purifier comes with an LCD screen that displays real-time readings of the current temperature, humidity level, and PM (particulate matter) count for your indoor environment. It also shows you how much time it has been running, and how much more time it needs to complete the cycle.

This is useful because you can make sure your air purifier is always running at an optimal level for maximum efficiency. The Dyson DP04 also comes with a timer so that you don’t have to wake up every hour or so just to check on it.

Operating Costs

The operating costs of the Dyson DP04 are relatively low. It consumes only 12 watts of power, which is very efficient. The annual cost to operate the DP04 is about $15. This makes it a very affordable option compared to other air purifiers on the market.

The filters also need to be replaced every six months. The filter replacements cost $39.95 each, so the annual filter replacement costs will be about $80.

The total operating cost of the DP04 is around $100 per year, which is very affordable compared to other air purifiers on the market today.


The Dyson DP04 Pure Cool Me HEPA Air Purifier has two filters, which are the combination of a 360-degree glass HEPA filter and an activated carbon filter.

Moreover, this unit also comes with a timer that allows you to set it automatically on/off at preset times during the day (up to 13 hours). Apart from that feature is its high-efficiency particulate arrestance mode (HEPA) technology that not only removes but also captures harmful airborne particles such as smoke, chemicals, and fumes. The Dyson DP04 is a great air purifier for people with allergies or asthma as it can help control their symptoms by removing allergens from the air.
