Frequently Asked Questions
What is a HEPA filter?
A HEPA filter, or high-efficiency particulate air filter, is a standard pleated mechanical air filter that can be found in many air purifiers. These ultra-fine filters are excellent at absorbing common household pollutants as they will catch most particles with a diameter larger than 0.3 microns. These filters are even more effective at capturing larger debris, which is why many manufacturers boast that they can remove more than 99 percent of airborne particles.
How often do I need to change the filter inside my air purifier?
When you purchase a new air purifier, it’s worth factoring the maintenance cost into the equation. Filters need to be periodically replaced once they become saturated, the cost and frequency of which can vary between models. In general, you should expect to replace your filters at least every six months.
