It pairs a True HEPA filter with an activated carbon layer and a washable pre-filter, is AHAM Verifide for 392 sq ft, and adds the Winix Smart app with schedules and filter-life tracking plus Home Assistant support and a longer two-year warranty. The Blueair Blue Pure 311i Max answers with a larger AHAM Verifide coverage, quieter operation, lower power draw and PM1, PM2.5 and PM10 sensing on a screen, but its filter runs about nine months and it lacks gas and VOC sensing. The Winix also carries a PlasmaWave ionizer stage and is not an ozone-free design, which the Blueair is. Choose the Winix 5510 for filtration, app control and value, and the Blueair Blue Pure 311i Max for a quieter purifier with a screen and the lowest running cost.

What the differences mean

Filter stack

The Winix 5510 uses a True HEPA filter rated to capture fine particles, plus an activated carbon layer for odours, a washable pre-filter and a PlasmaWave ionizer stage. The Blueair Blue Pure 311i Max uses a HEPASilent filter the brand does not certify as True HEPA, with no ionizer and no carbon layer for gases.

Coverage and airflow

The Blueair Blue Pure 311i Max is AHAM Verifide at a 283 CFM smoke CADR for rooms up to 439 sq ft, while the Winix 5510 is rated at 253 CFM for 392 sq ft. The Blueair moves a little more air, so it is the one to pick for the very largest room, though both are sized for a large living area.

Sensing and display

The Blueair Blue Pure 311i Max reports PM1, PM2.5 and PM10 on a screen and in its app. The Winix 5510 has no screen, puts its readings in an LED and the app, and does not report temperature, humidity, CO2 or formaldehyde.

Ozone and energy labels

The Winix 5510 includes a PlasmaWave ionizer stage and is not an ozone-free design. The Blueair Blue Pure 311i Max has no ionizer, is certified ozone-free and carries Energy Star, which matters to buyers who avoid ionizers.

Power and running cost

The Blueair Blue Pure 311i Max draws 32 W at its top speed and the Winix 5510 65 W, so over months of round-the-clock use the Blueair costs less to run. Its filter is rated for about nine months, while the Winix filter is rated for a year.

Which one to buy if

  • you have shedding pets, cooking smells or smoke to clear
    Winix 5510

    The Winix 5510 combines a True HEPA filter with an activated carbon layer and a washable pre-filter built for odours and hair.

  • you want an ozone-free, Energy Star certified purifier
    Blueair Blue Pure 311i Max

    The Blueair Blue Pure 311i Max has no ionizer and is certified ozone-free, where the Winix carries a PlasmaWave stage.

  • you want to see PM1, PM2.5 and PM10 readings
    Blueair Blue Pure 311i Max

    The Blueair Blue Pure 311i Max reports those three particle sizes on a screen and in its app, and the Winix shows no such breakdown.

  • you want app scheduling, filter-life tracking and Home Assistant
    Winix 5510

    The Winix Smart app adds schedules and filter-life tracking, and the Winix works with Home Assistant, which the Blueair does not.

  • you want the lower upfront price and the longer warranty
    Winix 5510

    The Winix 5510 costs less of the two and carries a two-year warranty against one year on the Blueair.

What owners say

Owners of both purifiers start with quiet: each is described as near-silent on its lowest setting, and both groups rely on an auto mode that ramps up on its own when smoke or dust appears. Blueair Blue Pure 311i Max owners point to the night mode they can sleep next to, the PM1, PM2.5 and PM10 readings and the washable fabric pre-filter, while their complaints are pricey replacement filters, a body larger than photos suggest and particle-only sensing. Winix 5510 owners single out the True HEPA filter, the sleep mode triggered by a light sensor and the Winix Smart app with filter-life tracking, and they warn that Turbo is loud, that linking Alexa needs a separate Winix account and a QR scan, and that the auto mode reads as over-sensitive in the first week.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.

The filter stack and the ionizer. The Winix 5510 uses a True HEPA filter with an activated carbon layer and a PlasmaWave ionizer stage, while the Blueair Blue Pure 311i Max uses a HEPASilent filter with no ionizer, which is why it is the ozone-free option and the Winix is not.

Yes. The Winix 5510 pairs a True HEPA filter with an activated carbon layer, a washable pre-filter and a PlasmaWave ionizer stage that buyers can switch off. The Blueair Blue Pure 311i Max has no ionizer and its filter is not certified as True HEPA.

Which purifier covers a bigger room, the Blueair Blue Pure 311i Max or the Winix 5510?

Who should buy the Winix 5510?

Homes with pets, cooking odours or smoke that want a True HEPA filter with an activated carbon layer, app scheduling and filter-life tracking, Home Assistant support and a longer warranty, and that do not mind a PlasmaWave ionizer stage or a louder Turbo speed.

Who should buy the Blueair Blue Pure 311i Max?

Buyers who want a near-silent purifier for a bedroom, an ozone-free and Energy Star certified design, the lowest running cost and particle sensing for PM1, PM2.5 and PM10 on a screen, and who can accept a shorter filter life and higher replacement cost.
