The Dyson DP04 air purifier boasts a 360-degree filtration system along with a HEPA and activated carbon filter. This allows it to cleanse the air of dander, dust, and other debris to help you breathe easier. Customers commonly note the high price tag. But when you feel better mentally and physically, it may be worth it.

Dyson DP04 overview

Various contaminants in the air can really upset your sinuses. Fortunately, the Dyson DP04 creates a cleaner, healthier home by thoroughly purifying any room it's in. It comes with a 360-degree filtration system and HEPA filter to remove gases, odors, and 99.97 percent of pollutants as tiny as 0.3 microns. Other features to benefit from with the DP04 include:

  • Smart home compatibility
  • Dual-functionality as a purifier and fan

Reasons to Buy Dyson DP04

  • You wake up feeling congested. A lot of people wake up with a runny or clogged nose. The bedroom is a haven for dust mites and other contaminants. But with the DP04 running on night-time mode all evening long, you can wake up feeling refreshed.
  • You want control from anywhere. The Dyson DP04 is compatible with the Dyson app. You can turn the device on from anywhere, even from work. You can turn the device on and get your house feeling great by the time you arrive.
  • You enjoy customization. The DP04 even comes with a custom mode where you manually adjust the settings to your liking. You have control over the angle of oscillation, air flow direction, and fan speed.

Reasons to Avoid Dyson DP04

  • You have Google Home. The Dyson DP04 is compatible with Alexa and Siri. However, it doesn't presently work with Google Home. So if you currently have that set up in your house, then it's not going to work with the DP04.
  • You want washable filters. You need to replace the filter annually, which should cost you around $79. Washable filters are more affordable in the long-term, and some people prefer those.
