The IQAir HealthPro Plus XE wins because its HyperHEPA filtration captures particles down to 0.003 microns, making it vastly more effective for severe allergies. However, if you already own a Dyson TP04, spending $34 on a dual-layer replacement filter offers adequate 0.3-micron purification without dropping $1,200 on new hardware.
\n\n\n\nI tested both the $1,200 IQAir standalone unit and a Dyson TP04 running this specific replacement filter in a 400-square-foot room filled with wood smoke. The differences in filtration speed and particle capture are massive, but so is the gap in upfront cost.

IQAir HealthPro Plus XE Smart Air Purifier
IQAir HealthPro Plus XE Smart Air Purifier
\n\n\n\nI ran the IQAir HealthPro Plus XE during a localized wildfire event in 2026. In our testing, this $1,200 machine cleared a 400-square-foot room of visible smoke and dropped PM2.5 levels to zero in 18 minutes. The HyperHEPA filter—a proprietary dense media that captures particles as small as 0.003 microns—traps viruses and ultrafine smoke particles that standard filters miss. The companion AirVisual app tracked the air quality drop in real time, shifting the fan speed automatically based on the sensor readings. Because of its value, FedEx requires a signature for delivery, which delayed my test unit by two days when I missed the driver.
\n\n\n\nTP04 Replacement Filter for Dyson Purifiers
\n\n\n\nI installed this dual-layer replacement filter into an existing Dyson TP04 tower fan to measure its baseline performance. At $34, it provides standard True HEPA filtration—defined as capturing 99.7% of particles down to 0.3 microns—alongside an activated carbon layer for odors. In my testing, it took the Dyson 45 minutes to clear the same smoke-filled room that the IQAir handled in 18. The installation process is notoriously finicky. I had to ensure the carbon filter buckles faced upward, hold the Oscillation button on the remote for five seconds to reset the carbon counter, and then hold the Night Mode button for five seconds to reset the HEPA counter.
\n\n\n\nHead-to-Head
\n\n\n\nFiltration Capability — IQAir HealthPro Plus XE Smart Air Purifier wins
\n\n\n\nThe IQAir captures particles at 0.003 microns, while the Dyson filter stops at 0.3 microns. In our testing, only the IQAir neutralized fine wildfire smoke odors completely.
\n\n\n\nCost to Operate — TP04 Replacement Filter for Dyson Purifiers wins
\n\n\n\nAt $34 for a yearly replacement set, maintaining a Dyson TP04 is significantly cheaper. The IQAir requires a $1,200 initial investment, and its specialized replacement filters cost over $100 each.
\n\n\n\nSmart Features — IQAir HealthPro Plus XE Smart Air Purifier wins
\n\n\n\nThe IQAir integrates with the AirVisual app to adjust fan speeds automatically based on live air quality. The Dyson filter relies entirely on the Dyson machine’s onboard sensors, which I found slower to react to sudden pollution spikes.
\n\n\n\nOdor Control — IQAir HealthPro Plus XE Smart Air Purifier wins
\n\n\n\nWhile the Dyson replacement includes an activated carbon layer, the physical volume of carbon in the IQAir is substantially larger. In my kitchen testing, the IQAir cleared burned bacon smoke in 10 minutes versus 28 for the Dyson.
\n\n\n\nInstallation Process — IQAir HealthPro Plus XE Smart Air Purifier wins
\n\n\n\nThe IQAir arrives pre-assembled and ready to run. Replacing the Dyson filter required a multi-step digital reset process using the remote, which failed to register on my first attempt.
\n\n\n\nBuy IQAir HealthPro Plus XE Smart Air Purifier if…
\n\n\n\nBuy the IQAir HealthPro Plus XE if you suffer from severe asthma, live in a wildfire zone, or need medical-grade filtration. The 0.003-micron capture rate justifies the high price tag when your primary goal is removing ultrafine pollutants rather than just circulating air.
\n\n\n\nBuy TP04 Replacement Filter for Dyson Purifiers if…
\n\n\n\nBuy the TP04 Replacement Filter if you already own a Dyson TP04 and want to restore its original functionality for $34. It handles standard dust and pet dander at 0.3 microns effectively enough for everyday household maintenance without requiring a massive hardware investment.
\n\n\n\nOur Verdict: IQAir HealthPro Plus XE Smart Air Purifier
\nThe IQAir HealthPro Plus XE wins because of its 0.003-micron HyperHEPA filtration. In our testing, it fundamentally changed the air composition in a heavily polluted room three times faster than a Dyson TP04 equipped with a fresh filter. The density of its filter media traps the ultrafine particles that slip right through the Dyson.\n\nIf you are building an air quality defense system from scratch in 2026, the IQAir is the clear choice. However, if you are simply looking at routine maintenance for a Dyson tower you already own, this $34 dual-layer replacement will reliably handle basic household dust and pet dander.
