The Levoit Eleva 300X is a lower mid-range air purifier, intended for use in small and medium-sized rooms. It sits alongside the older Levoit Core 300S in the manufacturer's lineup, with a similar footprint, design, and price, but with a new two-piece filter design, onboard display, and slightly more powerful fan motor. There's also a laser sensor that tracks a range of particle sizes, like traffic exhaust, fine dust, and pollen, and automatically adjusts fan speed depending on current air quality.
Our Verdict
The Levoit Eleva 300X is a decent option for pet owners. At its highest fan speed setting, its clean air delivery rate is sufficient for dealing with allergens like pet dander in medium-sized spaces, like smaller living rooms or dining areas. That said, it does get rather loud in that setting and might scare off more skittish pets. Conversely, it's almost inaudible at lower fan speeds, but performance degrades to the point where it's really only useful in smaller bedrooms or nurseries. On the upside, it's pretty feature-rich, with a laser particle sensor, Wi-Fi connectivity for remote operation and monitoring, and support for operating schedules.
Quiet operation at lower speeds.
Max particle filtration rate is sufficient for medium-sized spaces.
Relatively rich feature suite.
Performance drops steeply at lower fan speeds.
Somewhat noisy at higher fan speed settings.
The Levoit Eleva 300X is great for use in bedrooms. It has a dedicated low-noise Sleep mode for overnight operation that renders it practically inaudible, though it's worth noting that performance in that setting is only sufficient for really small bedrooms. You can also turn off its display to minimize distractions in a dark room. If you pair your smartphone to the Eleva 300X, you can set operating schedules or change settings, all without getting out of bed. Lastly, while it isn't necessarily the most compact option on the market, it's still small enough to fit on a dresser or nightstand.
Compact size.
Quiet operation at lower speeds.
Relatively rich feature suite.
Performance drops steeply at lower fan speeds.
The Levoit Eleva 300X's particle filtration rate is satisfactory. It's capable of operating effectively in smaller living areas or large primary bedrooms at its highest fan speed, but dropping that setting down severely compromises performance.
Max particle filtration rate is sufficient for medium-sized spaces.
Performance drops steeply at lower fan speeds.
The Levoit Eleva 300X has a pretty compact footprint. It's a little larger than the unit it replaces, but it still remains small enough to fit in a tighter nook, in between furniture, or even on a coffee table or dresser.

Popular Air Purifier Comparisons
The Levoit Eleva 300X is a lower mid-range air purifier. It sits alongside the Levoit Core 300S in its position near the bottom of Levoit's air purifier lineup; it's above the cheaper and smaller Levoit Core 200S, but below the pricier, more potent Levoit Core 400S. Compared to the older Core 300S, the Eleva 300X makes a few small but welcome improvements, with a user display that provides more useful information concerning air quality and a fractionally quieter fan motor. That said, it doesn't offer that much of a bump in performance, and similarly priced options like the Winix 5530 or even the Levoit Vital 200S provide a higher clean air delivery rate. That being said, it's worth noting that the Eleva 300X is notably smaller than either, making it a better fit for areas where space is at a premium.

The Levoit Eleva 300X is a slight improvement over the Levoit Core 300S. The Eleva 300X features a display that shows real-time particle levels, providing a more detailed assessment of air quality at a glance. It uses a different filter design with separate primary and activated carbon layers, so you don't need to replace both stages if only one is worn down. In terms of performance, however, the Eleva 300X provides only a marginal bump, with a slightly higher max particle filtration rate, superior performance at lower fan speeds, and a small reduction in operating noise.
The Levoit Core 400S is better than the Levoit Eleva 300X. The Core 400S has a significantly higher clean air delivery rate, making it a more effective option for larger spaces. The Core 400S also maintains its performance advantage at lower, quieter fan speeds, so it'll do a better job when running overnight in larger bedrooms. That said, it's worth noting that the Eleva 300X is considerably quieter across its fan speed range, and is smaller too.
The Winix C610 and Levoit Eleva 300X have different strengths. The Winix provides a higher clean air delivery rate at its highest fan speed setting, and it'll be more effective in larger spaces. That said, this gap in performance closes at lower, quieter fan speeds, where the Levoit delivers near-identical performance to the Winix. The Levoit is also considerably more compact and runs quieter, particularly at both units' highest fan speeds.
The Winix 5530 is a more versatile air purifier than the Levoit Eleva 300X. The Winix is the bulkier and slightly noisier unit of the two, but it has a considerably higher max particle filtration rate, allowing it to clear the air in an equivalently sized space roughly 40% faster. The Winix maintains a performance advantage at lower, quieter fan speeds too.
Test Results
The Levoit Eleva 300X features a similar but updated interface compared to the Levoit Core 300S. Like that model, the Eleva 300X's display allows you to toggle through its standard fan speed settings, toggle the low-noise sleep and automatic fan speed adjustment modes, lock the controls, and turn its display lights on or off.
That said, this unit also has a laser sensor that tracks PM1.0, which covers things like vehicle exhaust or wildfire smoke; PM2.5, which includes things like fine dust or pet dander; and PM10 particles, such as mold spores or pollen. You can toggle between the different particle levels by pressing on the directional arrow buttons on either side of the display. This provides a more accurate rundown on air quality compared to the Core 300S's LED ring, which cycled through different colors to give you a rough estimate of overall particle levels.
Connecting the device to your smartphone provides an expanded suite of features, allowing you to set operating schedules, check its filter status, and monitor changes in air quality up to four weeks prior.

Much like the Levoit Core 300S, the Levoit Eleva 300X uses a three-stage filter system comprised of a pre-filter for trapping lint or dust, a primary filter for smoke and fine dust, and a High-Efficiency Activated Carbon filter. Unlike the Core 300S and most other older Levoit models, the carbon layer is a separate filter that can be replaced separately, lowering the unit cost of the primary filter in comparison.
It's worth noting that the standard filter is advertised as HEPA-grade by the manufacturer. The testing standard Levoit references to certify that rating is ASTM F3150-18, which applies to HEPA vacuum filters, not air purifiers. As a result, we've opted not to classify the Eleva 300X's standard filter as HEPA certified.
The Levoit Eleva 300X's maximum clean air delivery rate is decent. At its highest fan speed, this unit can handle medium-sized rooms like large bedrooms or home offices, and smaller living rooms. That said, it shows only a marginal bump in performance over the older Levoit Core 300S.
At lower, quieter fan speeds, this unit's performance is adequate by the standards of its class. Its clean air delivery rate is sufficient for the average bedroom or nursery, though you'll need to turn its fan speed up if you plan on using it in a room larger than that.
This is a remarkably quiet air purifier. At its lowest fan speed setting, it's almost inaudible, making it a good option for overnight use in really small bedrooms. Operating noise is somewhat high, however, at its maximum speed, and it could prove to be a little disruptive if you have the unit set up near a desk or bed.
