Both the 200S and 300S have 4 fan speeds, produce the same amount of noise and have Smart, app-integrated features including scheduling and filter-change notification. They both also carry Energy Star Certifications and extremely high marks from owner reviews. Running it all time is best with modern models from Levoit, which have an integrated VeSync app, auto mode, air quality indicator, and many other advanced options.

First, there’s no way to tell whether the sensor that these machines use to determine their automatic on/off cycles is working properly. Second, depending on what a manufacturer determines as “poor enough” air quality, an automatic setting may let the air in your home get quite laden with particulates before kicking the purifier on. The AirSoap, unlike all the other purifiers we have tested, levoit filter does not contain a physical filter. Instead, it uses washable, electrically charged plates to capture airborne particulates. It did reasonably well in our testing, removing 95.2% of the smoke on high and 89.7% on medium. And the need to frequently wash the plates—and, once a year, take the whole machine apart and give it a deep clean—sounds like a hassle rather than a selling point.
While it doesn’t have an app to connect to or any smart features, our tester said that she would definitely buy this purifier because of its affordability and its effectiveness. In our various effectiveness tests, the Dyson Purifier Cool TP07 outperformed all expectations, clearing smoke quickly from the air and significantly improving local air quality. In September 2007, the California Air Resources Board announced a ban of indoor air cleaning devices which produce ozone above a legal limit. This law, which took effect in 2010, requires testing and certification of all types of indoor air cleaning devices to verify that they do not emit excessive ozone. Reactive Oxygen Species Technology also known as “ROS Purifier” – There are 7 airborne ROS.
Minor differences include the size and weight of each unit with the 200S being smaller than the slightly larger 300S. Levoit Air Purifier – Cleaning the Pre-FilterThe pre-filter is best vacuumed or cleaned with a dry cloth at least once a month, more if necessary. If you want to learn more about maintaining pre-filters, I have recently written a decent article about pre-filters and how to clean them. In addition, try to keep the devices as close to the modem as possible, especially if you are using a 5GHz modem, which has a much lower range by default.
Those figures slightly topped the results from our current large-space pick, the Blueair Blue Pure 211+, which came in at 99.3% and 99.2% on new filters and 99.3% and 98.4% on filters that had been run 24/7 for eight months. The two machines are similarly quiet, with the Airmega 400 registering 40 decibels on its quiet/high-medium setting and the Blue Pure 211+ measuring at 43 decibels on medium. But the Blue Pure 211+ comes out on top on cost, as it typically sells for $300 versus the Airmega 400’s usual price of $500.
You can also use customized presets with different profiles for a baby, your sleep routine, and other factors. Just as with Dyson’s vacuums and hair dryers, the brand’s humidifiers also include industry-firsts and thoughtful levoit filter designs. The Dyson Purifier Humidify+Cool Formaldehyde may one of the largest and is the most expensive humidifier that we tested, but the app-compatible, customizable features make it a standout choice worth the splurge.
While the design lacks any smart features, our tester said that this purifier was easy to operate because it has just one button to switch between its three settings. Air purifiers may be rated on a variety of factors, including Clean Air Delivery Rate ; efficient area coverage; air changes per hour; energy usage; and the cost of the replacement filters. Two other important factors to consider are the length that the filters are expected to last and the noise produced by the various settings that the purifier runs on. Filter HVAC at MERV 14 or above are rated to remove airborne particles of 0.3 micrometers or larger. A high-efficiency MERV 14 filter has a capture rate of at least 75% for particles between 0.3 and 1.0 micrometers. Although the capture rate of a MERV filter is lower than that of a HEPA filter, a central air system can move significantly more air in the same period of time.
Others have replaceable air purifiers that should be swapped out every few months. Your air purifier may have a special light to tell you when it’s time to replace the filter; otherwise, keep an eye on it after three months of use. The installed carbon filter removes odors from the air, and the UV light eliminates mold, bacteria, and viruses. The slim design on this purifier is great for smaller spaces and can easily be stored out of the way in your home.
