When you study the best air purifiers used at home, you will see the term "HEPA" again and again.Some air purifiers use HEPA filters, while others may use terms like "hepa-like" or "hepa-style."Which of these terms are you looking for, and which are just marketing terms?We'll take a closer look at what HEPA really means, what filters need to do to meet the standards, and what manufacturers really mean when they call their products "hepa-like."

Air purifiers work by moving air through filters and capturing elements that can cause pollution, allergies, asthma, illness and more.In addition, using activated carbon filters (a separate filter), they capture odors and chemicals in the air.
