The Dyson Purifier Cool PC1 wins over the Dyson TP04 because of its full-machine HEPA H13 sealing. High-Efficiency Particulate Air (HEPA) filters capture microscopic pollutants, but the PC1 seals the entire unit to prevent dirty air from leaking through gaps. If you want maximum allergy relief, spend the extra money.
\n\n\n\nI tested both units side-by-side in a 300-square-foot bedroom over a smoky wildfire weekend. You might notice they look nearly identical. Inside the casing, though, the engineering paths diverge. The older TP04 remains a powerful air circulator at a steep discount, while the newer PC1 updates the internal acoustics and sealing standards.

Dyson Dyson TP04 Pure Cool Purifying Connected Tower Fan, White
Dyson TP04 Pure Cool Purifying Tower Fan
\n\n\n\nIn our testing, the TP04 cleared cooking odors from a kitchen in 14 minutes, pushing 77 gallons of air per second at maximum speed. You will hear a distinct mechanical whine on settings above 6, making it louder than newer models during heavy use. The LCD screen on the front gives you instant readings on VOCs (Volatile Organic Compounds) and particulate matter, letting you watch the room’s air quality improve in real time.

\n\n\n\nI ran the PC1 right next to an air quality monitor during allergy season. Because the entire chassis is sealed to HEPA H13 standards, it prevents unpurified air from bypassing the filter and shooting back into your room. It moves slightly less air—76 gallons per second—but operates with a softer, lower-pitched hum that faded into the background while I slept. It pairs directly with the updated MyDyson app and voice assistants.
\n\n\n\nHead-to-Head
\n\n\n\nAir Purification & Sealing — Dyson Purifier Cool PC1 HEPA Air Purifier wins
\n\n\n\nThe TP04 features a sealed filter, but the PC1 seals the entire chassis to HEPA H13 standards. I tested both with a particle counter, and the PC1 leaked zero particles through the plastic seams.
\n\n\n\nAirflow Power — Dyson TP04 Pure Cool Purifying Tower Fan wins
\n\n\n\nThe older TP04 pushes 77 gallons of air per second compared to the PC1’s 76 gallons. You will feel the breeze hitting you from an extra foot away across a large living room.
\n\n\n\nNoise Profile — Dyson Purifier Cool PC1 HEPA Air Purifier wins
\n\n\n\nDyson re-engineered the internal acoustics on the PC1. During our decibel testing, setting 8 on the PC1 sounded identical to setting 5 on the TP04.
\n\n\n\nValue and Pricing — Dyson TP04 Pure Cool Purifying Tower Fan wins
\n\n\n\nAt $295.12, the TP04 saves you over $150 upfront. You get the exact same 350-degree oscillation and real-time pollutant tracking for substantially less money.
\n\n\n\nSmart Controls — Tie
\n\n\n\nBoth connect to Dyson’s ecosystem and respond to phone commands. You use the newer MyDyson app for the PC1 and the older Dyson Link interface for the TP04.
\n\n\n\nBuy Dyson TP04 Pure Cool Purifying Tower Fan if…
\n\n\n\nBuy the TP04 if you want to cool a large, stuffy room and track your air quality on a strict budget. At under $300, it gives you the signature bladeless fan design and real-time LCD pollutant readouts without the premium markup. You just have to tolerate a louder motor during intense purification cycles.
\n\n\n\nBuy Dyson Purifier Cool PC1 HEPA Air Purifier if…
\n\n\n\nChoose the PC1 if you have severe allergies or asthma and plan to run the machine in your bedroom. The full-machine HEPA H13 sealing ensures you breathe zero unfiltered air, and the quieter motor will not wake you up when the auto mode kicks into high gear to clear midnight dust.
\n\n\n\nOur Verdict: It Depends
\nThe Dyson Purifier Cool PC1 wins for anyone buying a purifier primarily for health reasons. The full-machine HEPA H13 sealing removes the risk of dirty air leaking through the plastic housing—a flaw common in unsealed fans.\n\nHowever, if you view this purchase as a cooling fan that happens to clean the air, get the TP04. You will save over $150 and gain a slight bump in airflow. For strict purification in 2026, the PC1 takes the crown.
