Winix C610: Specs, Features, Pros & Cons
At 3.8 kg the Winix C610 is light for a purifier sized for a medium-to-large room, and it fits a lot into that small body: four filtration stages, an air quality sensor, auto and sleep modes, the Winix Smart App and voice assistant support. It is the connected, current-production end of the Winix range.
The filter is one all-in-one cartridge, Filter Z, with an activated carbon layer built in and no separate pre-filter to wash. That makes maintenance a single swap once a year, and Winix puts a spare cartridge in the box, so the first change costs nothing. A single part also means nothing to separate or rinse between changes. PlasmaWave ionization is part of the four-stage stack, and it can be turned off by anyone who would rather not run an ionizer at all.
At the quiet end of its range it measures 22 dB, low enough for a bedroom as well as a living room. The timer, though, lives only in the app. Nothing on the purifier's own panel sets it, so a switch-off time at bedtime means reaching for a phone, and a household without the app installed goes without one.
Its rated area is enough for a family lounge, a large bedroom or an open study, and the purifier is light enough to carry between floors when the season changes. Winix publishes the room size but no clean air delivery rate, which makes it harder to line up against rivals that print theirs. A buyer who values a light purifier, an app and a predictable yearly filter gets all three, and the gaps show up in the paperwork and the timer more than in the room.

How this VS Score was computed
Score 62: each known spec is measured against the median of all air purifiers (41 products), then weighted; 50 means level with that median. In classes of six or more, a value beyond the class’s 10th–90th percentile range counts as that limit, so one extreme product cannot set the scale. 61% of the scoreable weight could be used; unknown values, features not applicable to this class and proxies (battery capacity where a rated life exists) add or remove nothing.

Editor’s note
Two things set the C610 apart from the Levoit and Dreo units around it. The first is that Winix still makes a genuine True HEPA claim and backs it with a laboratory report: 99.99% of particles down to 0.01 micron, from a KCL test Winix cites by document number. Levoit has retreated to HEPA-grade across its current range, so if certification matters to you, this is a real difference rather than marketing noise.
The second is filter economics. The C610 uses a single all-in-one Filter Z rated for a year, and the retail box ships with two of them, so the first two years of filtration are already paid for. Against Levoit's roughly seven-month cycle on a sealed cartridge, that makes this a materially cheaper machine to own.
There are trade-offs. Winix publishes no CADR figure for this model at all, which is unusual and mildly annoying. The stated 384 square feet implies something near 248 CFM, but Winix never states it, so treat that as arithmetic and not a specification. The timer exists only inside the Winix Smart App, and there is no button for it on the unit. And the PlasmaWave ionizer produces trace ozone, which Winix quantifies at 0.33 ppbv over an eight-hour average. That is very low, but if you are ozone-averse, know that it can be switched off and that switching it off is the right call for you.
Four filtration stages, a real sensor, Auto mode, app and voice support round it out.
For a medium-to-large room where you want a certified filter and predictable yearly costs, this is a straightforwardly sensible machine.

The bottom line
The Winix C610 earns a VS Score of 62, above the median of the 41 air purifiers it is measured against (a score of 50 is level with that median).
- Who it’s for
- Buyers who want a certified True HEPA filter and predictable yearly costs: one filter a year, with two already included in the box.
- Who should look elsewhere
- Anyone who needs a published CADR figure to compare like with like, or who wants a timer on the unit itself rather than buried in an app.
- The trade-off that matters
- Certification and cheap, simple filter replacement, against a maker that documents performance loosely. No CADR is published anywhere for this model.
- The main alternative
- Coway Airmega Mighty AP-1512HH covers similar ground with a clearly published smoke CADR, but has no app and draws considerably more power.
