The hardware is effectively the same: a washable fine mesh pre-filter, an AOC carbon layer, a True HEPA filter and a switchable PlasmaWave stage, with the Winix Smart app adding schedules and history. The Winix 5520 answers with a lower maximum draw, 50 W against 65 W, which only matters if you leave it running flat out all day. Pick the Winix 5510 for the price and its established owner track record; pick the Winix 5520 if the lower power figure is worth paying for.

What the differences mean

Power at full speed

The Winix 5520 draws 50 W at its top speed and the Winix 5510 65 W. That is the one measurable gap between them, and it only becomes meaningful if the purifier runs at full speed for hours every day.

Carbon filter design

The Winix 5510 uses Winix's AOC carbon filter, built from carbon pellets for odour and gas control. The Winix 5520 lists a standard activated carbon layer, so the older model is the one with the heavier carbon design on paper.

Model generation

The Winix 5510 arrived as a 2024 model and the Winix 5520 as its 2025 follow-up, so the newer one is the current generation on the shelf. In practice they share their CADR, coverage, filter stack and app, which is why the generation alone is a weak reason to choose.

Price positioning

The Winix 5510 is the more affordable of the two in this comparison, which is what decides it: the same measured airflow for less. The Winix 5520 has to justify its higher price on the lower draw and the newer model year alone.

Which one to buy if

  • you want the same clean air for less money
    Winix 5510

    The Winix 5510 matches the Winix 5520 on CADR, coverage and filter stack, and it is the cheaper of the pair.

  • the purifier runs at full speed for hours every day
    Winix 5520

    The Winix 5520 draws 50 W at its top speed against 65 W, so its lower draw is worth something only in constant, high-speed use.

  • you want the current-generation model on the shelf
    Winix 5520

    The Winix 5520 is the newer model year, though it shares the same performance figures as the Winix 5510.

  • you are adding Alexa voice control to a large room
    Winix 5510

    Both use the Winix Smart app and Alexa, so the cheaper Winix 5510 gets you the same smart control and a well-documented owner track record.

What owners say

The Winix 5510 is the side of this pair with owner reviews, and they are unusually consistent. Owners describe a large-room purifier that is near silent on its lowest speed, with an automatic sleep mode that dims the LEDs when the room goes dark, and they report it clearing wildfire smoke, cooking smells and pet odour until the air quality light settles back to blue. The app and the schedules get steady praise. The complaints are equally clear: linking Alexa needs a Winix account and a QR code and never feels native, auto mode reads as over-sensitive in the first week, Turbo is loud, and there is no screen on the unit.

Upgrading from the Winix 5510?

Stepping from the Winix 5510 up to the Winix 5520 changes remarkably little. The CADR, the 392 sq ft coverage, the three-stage filter, the PlasmaWave stage and the Winix Smart app are the same, so the only gains are a lower maximum draw and a newer model year. If your Winix 5510 is still working, there is no reason to replace it, and a first-time buyer should simply take whichever of the two is cheaper. The Winix 5520 makes sense only when the long-run power figure is the deciding factor and the prices are close.

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.

Frequently Asked Questions

What is the difference between the Winix 5510 and the Winix 5520?

Very little. They share the same 253 CFM CADR, the same 392 sq ft AHAM rating, the same washable pre-filter, True HEPA and carbon stack, and the same three-stage PlasmaWave design. The only measured difference is power at full speed, 65 W for the Winix 5510 against 50 W for the Winix 5520.

Which is better, the Winix 5510 or the Winix 5520?

The Winix 5510, because it delivers the same verified airflow and filtration for less. The Winix 5520 is the more efficient of the two at full speed and the newer model year, but it does not clean a room any better.

Do the Winix 5510 and the Winix 5520 work with Home Assistant?

Both do, through the community Winix integration installed with HACS, which signs in with the same Winix Smart account. Neither is a native Home Assistant device, and Winix does not allow simultaneous logins, so the integration and the phone app can knock each other out.

Is PlasmaWave switchable on the Winix 5510 and the Winix 5520?

Yes, both have a PlasmaWave button, so the ionizer stage can be left off. Winix publishes an ozone figure for these units, which is why neither is listed as ozone-free even with the stage switched off.

How often do the filters need replacing on the Winix 5510 and the Winix 5520?

Both rate the True HEPA and carbon filters for about twelve months, sold as a set. Only the fine mesh pre-filter in front is washable, so it is rinsed rather than replaced, which is what helps the two paid filters reach their full life.

Who should buy the Winix 5520?

A buyer who runs the purifier at full speed for long stretches and wants the lower 50 W draw, or who simply prefers to buy the newer model year. Anyone else is better served by the cheaper Winix 5510.
