The Winix C710 is a budget-friendly air purifier intended for medium-sized spaces. It's effectively a rebranded and lightly redesigned version of the Winix C610 and is sold almost exclusively at Costco, where it's bundled with an additional replacement filter. It features Wi-Fi connectivity, an air quality sensor that automatically adjusts fan speed, and a top-facing display that shows current PM2.5 particle levels, which include common airborne allergens like pollen and fine dust.
Our Verdict
The Winix C710 is a great option for pet owners. At its highest fan speed, its air-cleaning rate is sufficient to handle allergens like pet dander in smaller living rooms or large primary suites. That said, it's noisy at high fan speed settings, and it could be a disturbance to more skittish pets. Turning its fan speed down quiets it pretty significantly, though it also lowers its clean air delivery rate to the point where it's mainly suitable for average-sized bedrooms and home offices. Its onboard Wi-Fi lets you monitor air quality while you're away from home or even adjust settings manually. If you'd prefer a totally hands-off user experience, you can just have it run in its automatic mode.
Clean air delivery rate is sufficient for medium-sized areas at max fan speed.
Wi-Fi connectivity allows for remote operation, scheduling, and remote air quality monitoring.
Automatic fan speed adjustment setting reduces the need for manual intervention.
Can be disruptive at its highest fan speed.
Clean air delivery rate is only sufficient for small living areas at lower fan speeds.
The Winix C710 is great for use in bedrooms. It runs unobtrusively in its middle fan speed, while still offering a high enough clean air delivery rate to handle allergens within the vast majority of bedrooms, barring especially big primary suites. It also has a separate sleep mode that turns off its display to minimize distractions, though its performance in that setting is mainly only suited for especially small bedrooms. Its particle sensor allows it to automatically adjust fan speed, so you don't need to worry about the unit no longer keeping up if air quality dips overnight. You can set operating schedules for this unit too, so it doesn't run any longer than necessary, though doing so requires downloading its companion app.
Compact, lightweight design.
Wi-Fi connectivity allows for remote operation, scheduling, and remote air quality monitoring.
Almost inaudible at low fan speeds.
Automatic fan speed adjustment setting reduces the need for manual intervention.
The Winix C710's particle filtration rate is impressive. At its highest fan speed, it's sufficient for apartment living rooms or bigger primary suites. That said, compared to large units with bigger fans and more filter surface area, it's liable to struggle in really big open-concept areas.
Clean air delivery rate is sufficient for medium-sized areas at max fan speed.
Clean air delivery rate is only sufficient for small living areas at lower fan speeds.
The Winix C710 has a decently small footprint. It might be a bit hard to find space for it on a desk or dresser, but it won't take up much room on your floor, making it a solid choice for smaller bedrooms where floor space is at a premium.

Popular Air Purifier Comparisons
The Winix C710 is a basic, budget-friendly air purifier, available primarily at Costco. If you have a membership with that retailer, it's a pretty compelling option compared to the similar Winix C610, as it's often available at a lower price point and comes with an additional replacement filter, along with a display for PM2.5 levels. Even aside from its value proposition, it's a solid option, with a clean air delivery rate that punches well above its price bracket and size, comparing favorably to bulkier models like the Levoit Vital 200S and Coway Airmega Mighty2. That said, if you have a larger area to cover, the Winix C909 is a better option, and is another Winix model that is exclusive to Costco stores.

The Winix C710 is a better-performing air purifier than the Levoit Vital 200S. The Winix has a higher maximum clean air delivery rate and is thus able to operate more effectively in larger spaces. It also has a slightly smaller overall footprint, making it easier to set up in smaller bedrooms than the Levoit. With all that being said, the Levoit is noticeably quieter when both units are set to their max fan speeds, and it could be the more compelling option if you want an air purifier for a bedroom and are a light sleeper.
The Winix C610 and Winix C710 are essentially the same air purifier, with both units being well-suited for medium-sized spaces. The main difference is that the C710 is sold almost exclusively through Costco retailers; if you have a membership, it presents a better value proposition, as it's often available for less and comes bundled with an extra replacement filter.
The Coway Airmega Mighty2 and Winix C710 each have their own advantages. The Coway has a higher clean air delivery rate at lower, quieter fan speeds, making it a better option for continuous use where discretion is paramount, like a nursery or a bedroom. It also runs quieter at its highest fan speed. That being said, the C710 delivers nearly identical CADR at its highest fan speed and has a much more compact design, which makes it easier to set up in more cramped environments.
Test Results
This unit's control panel is nearly the same as the one on the Winix C610. The main difference is that the Winix C710 displays the concentration of PM2.5 particles that it intakes, though we're unable to independently verify this sensor's overall accuracy. There's also a filter replacement indicator light for the True HEPA filter, though this indicator doesn't provide a replacement reminder for the carbon layer or pre-filter.
The LED ring surrounding the panel changes color based on current conditions:
- Blue: Good
- Green: Average
- Yellow: Fair
- Red: Poor
Using the onboard controls, you can enable Sleep mode, turn the PlasmaWave ionization system on or off, and select its fan speed setting. There's no physical remote control, though, so to set up operating schedules, you'll need to use Winix's smartphone app.
It's worth pointing out that this unit's display only turns off when the unit is set to Sleep. Otherwise, it can only be dimmed. When Sleep mode is active, all indicator lights shut off entirely except for a single dimmed light on the Sleep button itself.
The Winix C710 uses the same 3-stage physical filtration system as the Winix C610, along with a separate particle ionization system. It has a fine-mesh pre-filter for trapping clumps of fur or bigger dust bunnies, a primary filter for dealing with common household allergens like pollen or pet dander, and an activated carbon layer to help reduce odors and other airborne pollutants. Although Winix call it a True HEPA filter and advertise it as trapping 99.97% of particles between 0.1 µm and 0.3 µm, they don't say which certification it meets. As a result, we don't classify it as a HEPA filter.
The so-called PlasmaWave system is meant to neutralize airborne pollutants and improve overall filtration performance. Like other ionizer-style technologies, it produces a small amount of ozone during operation, which can irritate the respiratory system for some people, particularly those with asthma or other respiratory sensitivities. That said, the manufacturer claims the ozone output stays well below the generally accepted safety threshold of 0.05 ppm, and the feature can be turned off independently if preferred.
It's worth noting that this system is present in other Winix units we've tested, and we didn't perceive a significant difference in filtration efficiency with the system turned on.
In terms of maintenance, Winix recommends vacuuming stuck-on debris from the pre-filter regularly, though no specific maintenance interval is given; for reference, the user manual for the similar C610 recommends cleaning the pre-filter every 14 days. The True HEPA filter and activated carbon filter are non-washable, and you'll eventually need to replace them, though they don't specify a replacement interval.
Unlike some higher-end purifiers that use denser activated carbon pellets, the C710 uses a thinner sheet of activated carbon, which translates to a lower odor-absorption capacity. Activated carbon filters generally need a significantly greater amount of carbon material to have a meaningful impact on odors and volatile organic compounds (VOCs); you can read more about that topic in our investigative report into air purifier performance.
At its highest fan speed, this unit has an impressive clean air delivery rate. It's capable of operating efficiently in medium-sized rooms like living rooms, primary bedrooms, and large home offices. It's liable to struggle a little in especially big spaces like basements or whole apartments.
It's also worth noting that we measured these results with the ionizer turned off.
This unit's particle filtration rate at lower, quieter fan speeds is okay. At fan speed 3 (the middle setting), its air cleaning rate is generally suitable for smaller bedrooms or offices, but any space bigger than that will require you to turn things up.
This air purifier is impressively quiet. In its Sleep mode and lower fan settings, it's nearly inaudible, making it a good option to run overnight in a smaller bedroom or nursery. However, its highest fan setting is a little on the louder end. At full speed, it reaches noise levels comparable to a TV at normal volume, so it can be disruptive in areas where you'd prefer some peace and quiet.
