One drawback is that the Core P350 costs $20 more than the Core 300. Since they’re so similar, if the pet-proof lock and upgraded filter aren’t needed for your home, stick with the Core 300. This device also doesn’t have a child lock, so parents will need to keep it away from a baby or toddler’s reach.
Activated carbon is merely a process of changing contaminants from a gaseous phase to a solid phase, when aggravated or disturbed contaminants can be regenerated in indoor air sources. Activated carbon can be used at room temperature and has a long history of commercial use. It is normally used in conjunction with other filter technology, especially with HEPA. All air purifiers, including Levoit units, emit visual and infrared light; both are harmless. When people see the price of Levoit units, they might suspect the performance is not on par with other more expensive air purifiers. With pets, the most important part of the filtration system is the pre-filter.

Other filtration technologies are harder to evaluate, including those that incorporate activated carbon and ultraviolet light. We don’t test these technologies specifically, so we can’t attest to their efficacy. Ease of levoit air filter use refers to just how user-friendly and intuitive each machine is to operate. The first thing we did was get out a stopwatch and time how long it took to go from the unopened box to have the machine up and running.
Much like your air conditioner, you’ll likely be keeping an air purifier on for as long as you plan on breathing the air in that room. In a lot of cases, that might be all day, so power consumption matters. Frugal users might want to check out the wattage specs on prospective models. There are also features that can mitigate that electricity drain, such as timers. It’ll cycle the air through a few times an hour, and you can adjust that number more or less with most models.
It’s small enough to fit on the coffee table as you play with Fido or by your bedside while you snooze. Because it’s so small and lightweight, you can bring it with you to every part of your home, which is ideal if you don’t want to cash out for multiple levoit purifier pricey appliances. An air purifier with a HEPA filter will capture particulate matter down to the size of airborne viruses, including COVID-19. That’s why you often see manufacturers claiming their products remove 99% of particles in the air.
Levoit is an American-based company with its headquarters located in California. They conduct all the research and development in their HQ, designing units to the highest specification to meet US standards. Once the purifier has been designed, it is then manufactured in China. Use these items to clean your home’s air, reduce the sources of respiratory problems, and limit the infiltration of new particulates. Install your purifier at least 18 inches from a wall and any furniture, ideally near the midpoint of the room you’re using it in.
To do so, we let 4 ounces of mothballs sit for 15 minutes in the closed tent. We then used the air quality monitor to measure and record the level of VOC gases in the chamber. We ran the air purifier for ten minutes, reading and recording the VOC level on our air quality monitor and the air purifier at the five and ten-minute mark. This model is unique in terms of aesthetics, allowing you to choose from solid colors, such as black and white, and also from artistic designs, such as Starry Night, Water Lilies, and Great Wave . Plus, the fact that it can be mounted on a wall could be useful for keeping the air purifier out of a pet’s reach or conserving floor space.
Using a high-grade MERV filter can be more effective than using a high-powered HEPA machine at a fraction of the initial capital expenditure. Unfortunately, most furnace filters are slid in place without an airtight seal, which allows air to pass around the filters. This problem is worse for the higher-efficiency MERV filters because of the increase in air resistance. Higher-efficiency MERV filters are usually denser and increase air resistance in the central system, requiring a greater air pressure drop and consequently increasing energy costs. High-efficiency particulate arrestance filters remove at least 99.97% of 0.3-micrometer particles and are usually more effective at removing larger and smaller particles.
In testing, we noted how convenient it is to monitor the air purifier on your phone. The app clearly indicates the quality of the air in a space, and it can also remind you when to change the filters. We appreciate that in addition to an auto and sleep mode, this product also has an eco mode that runs only when it detects a decline in air quality. Has a Pet Lock that prevents the change of settings by pets or children. It can cover up to 219 square feet and has a 3-stage filtration system that captures up to 99.97% of particles (0.3 microns) in the air.
