Levoit Core 300 - Best for a Budget

The Levoit Core300 is an affordable air purifier, that you can buy online and can clean air up to 200 square feet. The purifier was impressive in our tests. It reduced particulates by over 97% in 30 minutes on the high setting, in a New York City office measuring 135 square feet. It reduced particulates by 92% on medium. It is compact and attractive, measuring only 14 1/2 inches high and 8 1/2 inches wide.

The display-shutoff function ensures that it doesn't disturb sleep with bright lights. It's the most affordable pick of our choices, costing around $160.It's not very energy efficient. Running it on medium 24/7 consumes approximately $300 per year. Seven new filters cost $180. This makes it slightly more expensive over the long term than the Coway Mighty. It isn't as fast as the Mighty in larger rooms, nor the Blue Pure211+.

Are air purifiers effective?

Yes, they are. These appliances use fans and filters to remove particles from the air. These appliances can improve the air quality and make it easier to breathe. However, not all purifiers can meet this high standard. The sleek, stylish IKEA Förnuftig can capture 99.5% of smaller particles.

Even purifiers that are great at eliminating particles such as dust, smoke, and pollen, have the have mixed ability to remove smaller toxins like those found in cleaning products and paint. Another thing to keep in mind is that the effectiveness of purifiers in real-world conditions won't be as good as those in controlled lab environments. But they surely make your indoor environment much healthier.

Our findings have shown that indoor air quality concerns have increased significantly over the last few years. The pandemic has caused more people to search for ways to protect their indoor spaces, including offices, from airborne viruses and particulate pollutants. A HEPA filter in an air purifier will capture particulate matter that is smaller than the size of COVID-19.

Cleaning and Maintenance

Other than wiping down the housing from time to time, there is little need to clean the exterior. The filters inside an air purifier need to be cleaned regularly. The filters, whether made of paper, fiber, or mesh, should be replaced or cleaned every few months. For more information, consult the owner's manual. While some filters can be reused, they are not recommended for use on high-performance air purifiers. Models with a washable filter are an exception. This feature is designed to capture large particles before reaching the primary filter. It can reduce operating costs and extend the life of the main inner filter.


For the best air cleaning, the purifier should be run every day that you are home. All of our picks have been UL-certified for safety. However, as with all electrical devices, be aware of potential fire hazards like frayed wires. If noise is an issue, such as in the bedroom, the machine could be set to high while you are out of the room and then turn it down to a lower setting to cool you off before you go to bed. Keep all windows and doors shut so that the unit doesn't clean air from the outside. Make sure that there is no obstruction to airflow from the device by closing curtains, furniture, or other objects.
