The Environmental Protection Agency (EPA) ranks indoor air pollution as one of the greatest environmental health risks.1 These pollutants include things like dust, pet dander, pollen, mold spores, bacteria, and viruses. Odors associated with tobacco smoke, cooking, pesticides, and building materials can also affect your home’s air quality.
Thankfully, modern air purifiers can help remove myriad irritants from your home. Choosing the best purifier for your household starts with determining what pollutants you need removed and how much you want to spend.
Here’s a comprehensive SafeWise review of five top-rated home air purifiers and how to choose the best one for your needs. We’ve included several top brands at a variety of price points along with each unit’s features, benefits, and potential drawbacks.

Take the Next Steps
Evaluate the effectiveness of the air purifier you want: read customer reviews, learn about its features, and verify its air-cleaning efficiency. Don’t forget to take room size into account, too—using a purifier in a room that’s too big could drastically affect its usefulness.
While we focused on portable air purifiers here, whole-home purifiers are another option. If you need to operate an air purifier in several rooms of your home at once, a whole-home unit may be more cost effective than purchasing several portable devices.
Now that you know more about the benefits of air purifiers and how to choose the best one for your needs, head over to Amazon and shop around. In addition to purchasing an air purifier, consider ways to minimize or eliminate your home’s pollutants. For example, restrict smoking to outdoors, brush pets often to remove excess hair, and use nontoxic household and yard products.
