Every time you open a window or a door, even for a second, you’re introducing your home to a wide range of airborne pollutants that can create serious health issues over time. To keep indoor air as free of pollution as possible, you’re going to need to invest in an air purifier.

Levoit Air Purifier for Home Allergies Review [Core 300]

The Levoit Core 300 is a neat little air purifier that, despite its size, is designed to tackle the toughest indoor-air cleaning jobs. Although its performance is limited by its tiny housing and tinier motor, for its size, it’s one of the most powerful air purifiers designed for single-room use.

360° Cleaning

One thing that stands out about the Levoit Core 300 is its cylindrical design. The main benefit of this design is that the fan can suction in every direction, allowing users to place the unit anywhere they’d like without focusing on one particular area of a room. So wherever airborne particles are, they’re not safe from the Core 300’s full-circle suction.

215-square-feet Coverage

When it comes to finding the right air purifier, you first need to establish how large of a room the appliance should cover. The Levoit Core 300 is rated to cover a maximum of 215 square feet. For bedrooms and home offices, the Core 300 is something that would work superbly without overkill. Kitchens, basements, attics, and hallways, probably not so much…

Efficient Delivery Rate

In a 215-square-foot room, the Core 300 can filter the air up to five times per hour while maintaining moderate CADR figures (141 smoke, 140 dust, and 145 pollen). These CADR ratings are far from being the highest you’ll ever find, even in compact models, but when placed in appropriately sized rooms, users will notice a significant difference between pre- and post-filtration.

3-Stage Filtration with True HEPA Filter

Like most air purifiers nowadays, the Core 300 uses a 3-stage filtration system. The first stage is an activated carbon pre-filter that traps a majority of the larger particles. The air then passes the second filter – a True HEPA Filter that’s rated at 99.97% effectiveness in capturing and retaining particles as small as 0.3 microns (pet dander, pollen, dust mites, etc.). The final filter is a high-grade granular carbon filter that’s designed to remove odors from cooking and tobacco.

Customizable with 4 Filter Options

The Core 300 is compatible with four different filter options, each designed to tackle different airborne pollutants. Each of these filter options have True HEPA Filters in their cores; the only differences between each type is their outer filters which are specifically designed to different purifying jobs.

The four available filter sets are Original for all-purpose filtration, Mold Bacteria for use in moist environments, Pet Allergy for pet owners, and Toxin Absorber for those living in polluted cities. Upon purchase, you’ll get an Original set (need to install yourself).

Quiet Operation

One of the best features of the Levoit Core 300 is its super-quiet operation. The air purifier uses three manually-selected fan speed settings, each generating hardly any sound. From lowest the highest, the Core 300’s fan produces only 25 to 50 decibels. The lowest setting is quiet enough as to not disturb your slumber.

Levoit Core 300 vs. Vista 200

If you find the cylindrical design of the Core 300 as attractive as we do, then you’ll want to consider the other Levoit models out there. In appearance, the Levoit Vista 200 looks identical to the Core 300, but it’s what’s under the soft-edged casing that matters most.

Levoit Core 300 vs. Vista 200

The Core 300 and Vista 200 are very similar in many ways. First, they both utilize a 3-stage system to filter large and small particles, as well as VOCs like chemical, cooking, and tobacco odors. They both do a superb job in their respective room capacities.

Speaking of which, the main difference, performance-wise, between the two is the Vista 200’s smaller coverage. This air purifier is designed to manage air quality in rooms as small as 170 square feet, about 20% smaller than the Core 300. This unit is designed specifically for use in bedrooms and other similarly sized spaces.

Although the Vista 200 is smaller in terms of room capacity, it comes with several added-convenience features missing in the Core 300. There’s a sleep mode which further reduces the noise generated from the fans, a timer option that can be set up to eight hours, and a nightlight with two brightness settings.

Levoit Vista 200

Oddly enough, the CADR ratings of the Vista 200 are currently unavailable. This can be seen as a huge downside since, as a voluntary program, Levoit isn’t required to test every model. We can only assume from its size and limited 40-CFM airflow rate that the Vista 200 isn’t meant to eliminate copious amounts of air pollution.

Levoit Core 300 vs. LV-H133

The Levoit LV-H133 retains the standard cylindrical housing with 360° aim we know and love, but this is not a compact air purifier by any standard. But don’t let its larger size discourage you; its larger housing and beefier motor allow for much more efficient air filtration than the Core 300.

Levoit Core 300 vs. LV-H133

This product’s specific CADR ratings for smoke, dust, and pollen are also currently unreleased. However, this isn’t as big of a problem as in the previous model since the LV-H133 has an airflow rating of 235 CFM in rooms as large as 1,300 cubic feet. That’s mighty impressive for an air purifier designed for use in 538-square-foot spaces (kitchens, living rooms, garages, attics, and so on).

Like the Core 300, the LV-H133 uses a 3-stage filtration system with a carbon pre-filter, a True HEPA Filter, and a granular carbon filter for microscopic, medium, and large particles. Pet owners and sufferers of seasonal allergies will definitely enjoy the sensation of clean air with an LV-H133 at home.

As a larger model, the LV-H133 comes with better features. First is the smart detectors that constantly monitor the quality of indoor air before adjusting the fan speed between low, medium, and high speed. You can turn the unit on, set it on auto mode, and let the unit think for you.

The LV-H133 also features a filter indicator which shins bright when the HEPA filter becomes too clogged. This eliminates most of the guesswork when deciding when to replace the filter, though it has a maximum life expectancy of 8 months.

Levoit Core 300 vs. LV-H132

The LV-H132 is a lot like the LV-H133 in design and available features, but coverage-wise, it’s closer but a lot less than the Core 300.

Levoit Core 300 vs. LV-H132

The LV-H132 is designed to be placed in rooms up to 129 square feet, making it the smallest Levoit air purifier of the bunch. This isn’t a bad thing at all if your plan is to purify the air in a room or home office. Averaged-sized kitchens and living rooms are definitely out of the question.

In a nutshell, the LV-H132 can be described is a tiny air purifier with features that are akin to more technologically advanced models. It comes with smart sensors that detect the presence and concentration of airborne particles before switching the fan on to one of the available speeds.

The sleep mode feature eliminates loud gurgling noises coming from the LV-H132 to promote better sleep while ensuring cleaner air. You can also turn the LED lights off if they bother you at night.

If you prefer, you can ditch the auto mode altogether and activate the timer. The LV-H132 can be configured to clean air from anywhere between 1 and 12 hours. This timer is a lot more flexible than the Core 300.

Levoit LV-H132

Levoit refuses to disclose the CADR ratings for smoke, dust, and pollen, but judging by the LV-H132’s minuscule 40-CFM airflow rate, you can’t realistically expect much from it. It’s just strange that an air purifier like the LV-H132 would come with all the bells and whistles while only working effectively in tiny rooms.

Levoit Core 300 vs. LV-PUR131

The final Levoit comparison is between the Core 300 and the LV-PURI131. This is not to be mistaken with the LV-PURI131 –WiFi that, as its name suggests, can connect to your home’s router.

Levoit Core 300 vs. LV-PUR131

First of all, the LV-PURI131 is unlike any of the previous Levoit air purifier models in the sense that it’s not cylindrical in design. It looks more like a traditional air purifier with its boxy design, one-direction suction inlet, and horizontal control panel with a digital display.

Appearances aside, the LV-PURI131 is a much more powerful unit compared to the compact Core 300. This model is suited for rooms as large as 322 square feet, and its 312-CFM airflow delivery rate is powerful enough to filter air up to five times every hour. The CADR ratings only tell us how quickly it works and not how effective it is in capturing smoke, dust, and pollen.

It comes with the same features as the LV-H133 and LV-H132: filter indicator, auto, and sleep modes, three fan speed settings, 3-stage filtration including a True HEPA Filter, and a built-in 1- to 12-hour timer.

The main difference between the CORE 300 and the LV-PURI131 is the convenience factor. If you get the Core 200, you need to manually switch between fan speeds, whereas the LV-PURI131 can change fan speeds on its own. There’s also the room-coverage factor; the Core 200 is extremely limited compared to the LV-PURI131’s 322-square-foot coverage.

Levoit LV-PUR131

When shopping for an air purifier, bigger is almost always better, and convenience-adding features just sweeten the deal. We’d recommend the LV-PURI131 over the Core 200 any day of the week.
