Quick verdict
The 5510 takes the proven Winix formula — True HEPA, activated carbon, and PlasmaWave you can turn off — and adds Wi-Fi, an app, and a smarter auto mode, covering rooms up to about 392 sq ft. It's a sensible mid-range choice if you specifically want app control and scheduling on top of solid coverage; if you don't, the cheaper 5500-2 does most of the same work.
Ideal for
- Living rooms up to ~392 sq ft
- People who want app control and scheduling
- Buyers upgrading from a basic budget unit
Not ideal for
- Shoppers who don't care about the app (buy the 5500-2)
- The quietest possible high-speed operation

The in-depth review
The Winix 5510 is the modern replacement for the popular 5500-2, adding Wi-Fi and app control to a proven mid-size formula. If you liked the idea of the older Winix but wanted to run it from your phone and cover a slightly bigger room, this is the one to get, at around $180 to $200. The verdict: a smart, capable mid-tier machine, though it trades some of its predecessor's quiet running for the upgrades.
How it performs
The 5510 carries a combined CADR of 253, which lands it comfortably in mid-size-room territory and backs up its 392-square-foot rating, a touch more coverage than the 5500-2's 360. That output clears a busy living room or large bedroom at a good pace, and it has enough muscle for smoke episodes when you follow the rule of matching CADR to your room's square footage. For a room around 250 square feet, the 5510 turns the air over briskly.
Filtration is a familiar three-stage stack: a washable pre-filter, a True HEPA filter capturing fine 0.3-micron particles, and an activated carbon layer for odors and some gases. As with other Winix units it includes PlasmaWave, an ionizing step. Because ionizers can generate trace lung-irritating byproducts, it's worth knowing that PlasmaWave is optional and can be turned off, and the True HEPA filtration works fully without it. Switch it off if you'd rather stick to purely mechanical cleaning.
Filters and running cost
Replacement filters run about $80 a year, higher than the older 5500-2's roughly $50, largely because the 5510's carbon media is part of the replaceable filter rather than a washable piece. Over three years that's about $240 in filters on top of the $180-to-$200 purchase price. It's still reasonable for a mid-size smart purifier, but it's the clearest trade-off against its cheaper predecessor: you pay a bit more to own it long term in exchange for the app and the extra coverage. Our filter cost calculator can show your exact spend, and keeping the washable pre-filter clean helps the main filter last.
Noise and living with it
The 5510 is louder than some rivals. On its lowest setting it measures around 40 dBA, higher than the 5500-2's 28, and it climbs to about 66 dBA at top speed. That means even the quiet setting is audible, so light sleepers should test it before committing to a bedroom. It draws 65 watts on high. The upside is the smart layer: auto mode uses a built-in air-quality sensor to adjust the fan automatically, and full Wi-Fi with app control lets you schedule it, monitor readings, and adjust settings remotely or with a smart speaker. That connectivity is the main reason to choose the 5510 over the older model.

Frequently asked questions
Is the Winix 5510 worth it over the 5500-2?
Only if you want the smart features. The 5510 adds Wi-Fi, an app, and scheduling and a touch more coverage; the 5500-2 has the same core filtration for less. Pick the 5510 if app control matters to you.
What area does the Winix 5510 cover?
Up to roughly 392 sq ft at the strict 4.8 air-changes standard — enough for most living rooms and large bedrooms.
Can I turn off the Winix 5510's PlasmaWave?
Yes, and you can leave it off. The HEPA and carbon filters do the cleaning; PlasmaWave is an optional ionizer.
