On medium, running around the clock, they consume only about $6 worth of electricity per year. Replacement filters cost $19, and if you stick to the six-month replacement schedule, they add up to just $171 over the course of five years. The total five-year running costs are thus just $200, about 60% less than the costs of the Levoit Core 300.

There’s no option to set a timer or schedule when it operates, nor can you choose from any “eco” or power-saving modes. If you’re just looking for an air purifier to run at night in a bedroom, however, this will get the job done. Overall, we were impressed with the Levoit Core 300 Air Purifier and the number of impressive features it offers for such a compact unit. We found that it’s a durable and high-quality air purifier, and its size is convenient for smaller spaces like apartments, offices or bedrooms. After using several air purifiers from other top brands, we noticed an immediate improvement to our air quality, especially concerning our allergies and lingering smoke from the fireplace.
When retesting our existing air-purifier picks, Tim took four measurements, two using the old filters and two using new filters, to get a picture of how their performance changed over time. However, in the US air purifiers cannot be marketed as medical devices. That’s because it is exceptionally difficult to disentangle the known air-quality impacts listed above from other environmental and genetic factors that influence health.
And in that test, we learned that we had to run the machines on high to get meaningful purification . One of the keys to the AP-1512HH’s performance is its build quality, particularly the tight fit of its prefilter and HEPA filter. The prefilter captures large particles, such as pet hair and lint, that would otherwise block the HEPA filter and reduce its ability to capture fine particulates. The HEPA filter, meanwhile, fits snugly into the AP-1512HH’s frame, sealing tightly against the plastic housing. That prevents air from bypassing the filter around the edges and ensures that virtually all air drawn through the machine gets HEPA-filtered.
I turned the fan to its highest setting and it cleared the air within 10 minutes, according to the monitor on the unit. It weighs 11 pounds and it’s levoit air filter not small, running about 20 inches tall and 10 inches in diameter. It’s made for large rooms, with an effective range of up to 403 square feet.
The purifier has a touch-sensitive control panel on the top that lets you customize it via three impressive fan speeds. Just keep in mind that the highest speed setting is the most efficient in getting more airborne particles at a time. And despite its impressive cleaning abilities, you’ll love that it produces just a tiny bit of noise, up to 25 decibels. Using 28 watts of power, the compact air purifier can cleanse the air in smaller rooms up to 129 square feet.
