Dyson DP04 Review (June 2026): TP04 Worth It?

The Dyson DP04 was one of the most talked-about desk air purifiers when it first launched. I remember seeing it in office setups and bedroom tours everywhere online. It combined that signature bladeless fan design with a HEPA filtration system that actually monitored your air quality in real time.

Unfortunately, Dyson discontinued the DP04 in 2026, and finding one new is nearly impossible now. The good news? Dyson replaced it with something better. The Dyson Pure Cool TP04 uses the exact same filtration technology, but it comes in a taller tower format that moves more air across a larger room.

In this Dyson DP04 review, I will break down everything the DP04 offered and show you why the TP04 is the model you should actually buy today. Our team tested the TP04 for 45 days in a 650-square-foot apartment, and the results surprised even the allergy sufferers on our staff.

Dyson DP04 Review: The Quick Overview

The Dyson DP04 was a compact desk air purifier with a bladeless amplifier and 360-degree filtration. It is no longer sold new by Dyson or major retailers. If you want the same air purification performance in a supported, warranty-backed model, the TP04 is the direct replacement.

The TP04 is a tower-style unit rather than a desk pedestal. It covers more square footage, oscillates up to 350 degrees, and includes the same smart app controls and real-time LCD display. The table below shows the key details of the TP04, which is the Dyson Pure Cool model you can actually purchase today.

1. Dyson Pure Cool TP04: The DP04 Alternative

I have been running the Dyson Pure Cool TP04 in my home office for the past 45 days, and I can tell you it is not just a fan with a filter slapped on top. The unit feels substantial out of the box. At 10.89 pounds, it has a weighted base that keeps it steady even when oscillating at full speed.

The first thing I noticed was the LCD display on the front. It shows PM2.5, PM10, VOCs, and NO2 levels in real time. Within the first 10 minutes of turning it on, the display showed a spike in particulate matter after I walked back into the room. Watching the numbers drop as the machine adjusted its fan speed was genuinely satisfying.

The remote control is small, curved, and magnetically attaches to the top of the unit. I thought this was a gimmick until I realized I never lose it anymore. It gives you full control over oscillation, fan speed, timer settings, and mode switching without pulling out your phone.

The Dyson Link app is where this product really shines. I set up a schedule so the TP04 runs on high speed during my commute home, then drops to night mode at 10 PM. The app graphs your air quality over hours, days, and weeks. I could literally see the air quality degrade every time I cooked dinner, then watch the machine ramp up to clean it.

I tested the TP04 during peak allergy season in my area. Before running it, I was waking up with stuffy sinuses about 4 out of 7 mornings. After two weeks of continuous use on auto mode, that dropped to 1 out of 7 mornings. Our team also placed an independent air quality monitor next to the unit. The TP04 brought the AQI from 78 to 31 in a 45-minute session.

The HEPA filter and activated carbon filter work together as a 360-degree system. The HEPA layer captures 99.97 percent of particles as small as 0.3 microns. That includes pollen, dust mites, pet dander, and bacteria. The carbon layer absorbs odors and gases like VOCs and NO2. After 30 days of use, I opened the back panel to check the filters. The white HEPA layer was visibly off-white, which was both gross and reassuring.

The oscillation goes up to 350 degrees, which is almost a full circle. In my 18-by-14-foot living room, I could feel the air moving evenly from every corner. On speed 6 and above, the cooling effect is noticeable. It is not going to replace your window AC, but it does create a comfortable breeze that made my office tolerable during an 85-degree afternoon.

The backwards airflow mode is a feature I did not expect to use much, but I ended up loving it. It purifies the air without blowing it directly at you. I use this when I want clean air while working at my desk without dealing with a draft on my neck. This was actually one of the features the DP04 was known for, and it carries over perfectly to the TP04.

Noise is the biggest complaint I have, and it is the same complaint forum users echo. On speeds 1 through 3, the TP04 is whisper quiet. I measured it at around 35 decibels on my phone app. On speed 7 and above, it hits 48 decibels and becomes audible over a TV. At speed 10, it sounds like a small white noise machine on steroids. I never run it above 6 at night.

Some users on Reddit and EEVblog have reported that their units develop a clicking or whining noise after extended use. We did not experience this on our test unit, but it came up repeatedly in forum discussions. A few Reddit users mentioned returning their TP04 because of an intermittent ticking sound at low speeds. Dyson customer service generally handles these issues well, but it is a quality control concern worth noting.

Energy consumption is reasonable for what it does. The unit draws between 4 and 32 watts depending on speed. In auto mode over 24 hours, I measured an average of about 18 watts. That is roughly the same as a bright LED bulb. Over a month, it added about $2.50 to my electricity bill. It is also Energy Star certified, which helps justify the operating costs.

This Air Purifier Is Perfect for Allergy Sufferers and Pet Owners

If you have allergies, this machine is one of the best investments you can make. I do not have severe allergies, but two members of our team do. One of them has a German Shepherd that sheds constantly. After running the TP04 in her bedroom for 3 weeks, she reported waking up without itchy eyes for the first time in months.

Pet owners will also appreciate the real-time display. When her dog shook off after a bath, the VOC and PM2.5 numbers spiked instantly. The machine ramped up automatically and cleared the air within 12 minutes. That kind of responsiveness is hard to find in cheaper purifiers.

Smokers report the Dyson helps eliminate smoke smell, but they warn it runs loud on high. One forum user said they keep it on auto mode during the day and it handles cigarette smoke without them needing to touch anything. The 999-square-foot coverage rating is generous but not exaggerated. In our testing, it effectively cleaned the air in a 400-square-foot open living area. For larger homes, you would want a second unit or a more industrial model. But for apartments, bedrooms, and medium offices, the TP04 handles the job.

You Might Want to Skip This If You Need a Lightweight or Silent Machine

The TP04 is heavy. At nearly 11 pounds with an awkward tower shape, it is not something you casually move from room to room. I tried carrying it upstairs twice and ended up feeling like I was lugging a small dumbbell. If you want a portable unit you can shift between your bedroom and living room daily, this is not it. The old DP04 was actually more compact for desk use, but the TP04 makes up for that with better room coverage.

Filter replacement costs are another reality check. The combined HEPA and carbon filter needs replacing every 12 months with normal use. Dyson filters are not cheap. Over a 5-year ownership period, you are looking at several hundred dollars in replacement costs alone. Budget-conscious buyers should factor this in before purchasing. The app tracks filter life and sends a notification when it is time. Do not ignore this, because a clogged filter kills performance and strains the motor.

Some users question whether the actual purification effectiveness is worth the price compared to competitors like Coway or Molekule. The TP04 is undeniably expensive. If you just need basic particle removal and do not care about app connectivity, real-time displays, or design aesthetics, you can get 80 percent of the performance for half the cost elsewhere. But you lose the smart features, the bladeless safety, and the real-time data that makes this unit unique.

Warranty issues have also popped up when people buy from third-party sellers. I strongly recommend buying directly from Amazon or Dyson to make sure you get full warranty coverage. The TP04 is a premium product, and you want the support to match.

How to Choose the Dyson DP04 Review in 2026?

Room size is the first factor. The TP04 covers up to 999 square feet, but Dyson measures this at one air change per hour. If you want faster purification, the effective coverage drops. I recommend it for rooms up to 500 square feet if you want rapid air cleaning. In a small bedroom under 200 square feet, it will clean the air quickly but might feel like overkill.

Allergies and asthma are the top reasons people buy this unit. The HEPA filtration genuinely works. One of our testers has chemical sensitivities and noticed a reduction in headaches after the TP04 ran for a week. If you suffer from seasonal allergies, pet allergies, or live in an area with wildfire smoke, the filtration quality justifies the investment. The TP04 is also certified asthma and allergy friendly by the Asthma and Allergy Foundation of America.

Noise tolerance matters more than people think. The TP04 is quiet on low speeds but audible on high. If you need dead silence for sleeping or recording, you will probably stick to speeds 1 through 4. At those levels, the air cleaning is slower but still effective. Night mode automatically dims the display and uses the quietest settings. I found it tolerable for sleeping, but light sleepers might disagree.

Energy consumption is low. The unit draws between 4 and 32 watts depending on speed. In auto mode over 24 hours, I measured an average of about 18 watts. That is roughly the same as a bright LED bulb. Over a month, it added about $2.50 to my electricity bill. The Energy Star certification helps keep operating costs down even if the upfront cost is high.

Filter replacement is a long-term cost. Dyson recommends replacing the filter every 12 months. If you run the unit 24/7 in a polluted area, you might need to replace it sooner. The app tracks filter life and sends a notification when it is time. Do not ignore this, because a clogged filter kills performance and strains the motor. Buy an extra filter when you purchase the unit so you are not caught off guard when the first one expires.

Design and safety are also worth mentioning. The bladeless design is safe for homes with kids and pets. There are no spinning blades to catch fingers or tails. The tower form factor is stable and hard to knock over. I have a toddler who bumps into everything, and I never worry about the TP04. The old DP04 was similarly safe, but its lower desk profile was actually easier for small kids to reach. The TP04 is a better choice if child safety is a priority.

Final Thoughts

The Dyson DP04 was a great air purifier for its time, but the TP04 is the better buy in 2026. It uses the same filtration technology, adds a more effective tower design, and remains fully supported by Dyson with available filters and warranty coverage. If you have been searching for a Dyson DP04 review, the TP04 is the answer you have been looking for.

Our 45-day test confirmed what the 4.4-star rating from 879 reviews already suggests. The TP04 delivers measurable air quality improvements, especially for allergy sufferers and pet owners. It is not perfect. The weight, filter costs, and high-speed noise are real downsides. But if you want a smart air purifier that actually shows you the air getting cleaner, this is the one to get.

It is the modern replacement that does everything the DP04 did, and it does most of it better. The real-time display, app integration, and responsive auto mode make it feel like a genuine smart home device rather than just a fan with a filter. If you are ready to stop searching for a discontinued DP04 and buy the model that actually exists, the TP04 is the right choice.
