HEPA air purifiers are designed to force air through a filter, which is capable of removing at least 99.97% of airborne particles 0.3 microns in diameter in a single pass. The Levoit Core 300 is a great option for those looking to clean the air in a space of about 200 square feet. Apps for both iOS and Android are available, but they offer little more than a graph to track machine readings and the ability to control the fan speed remotely. Air filtration systems are one of the best ways to remove allergens and other harmful materials from the air.
For this reason, it is recommended that installation of a home air purifier be done by a licensed HVAC professional. The annual cost of running an air purifier will depend on how often you change the filter and how often you use it. Since 1999, HEPA purifiers have been studied for their ability to reduce particulate air pollution. A fan draws particles suspended in the air through a dense felt-like filter with billions of small voids of different sizes.
It is advisable to “oversize” your purifier, which will allow you to run it in slower and quieter environments while still effectively cleaning the air in a room. It is more important to measure the effect of a filter on the total particle load in the room than it is to focus on individual particles.
