Every product you read about on HouseFresh
has been tested in our home.
We buy every air purifier we test.
To avoid bias, we don’t accept paid offers to review devices or free products in exchange for glowing reviews. We buy the devices we test with our own money to be free to tell it exactly as it is and to experience the full customer journey the way you would.
We test every device under the same conditions.
We test all our air purifiers following the same process to confidently compare performance data across different brands and models. We record all our experiments on video so you can see exactly how each device performed across all performance tests.
We don’t ignore the long-term costs.
You should use your air purifier every day for as long as you need it, and that costs money. That is why we don’t just focus on upfront costs. Instead, we collect first-hand data on the long-term costs associated with replacing filters and the energy consumption that you can expect.
We tell you when a product sucks.
We are truly free to say exactly what we think — especially if a device fails to perform. HouseFresh is an independent publication that doesn’t accept money in exchange for positive reviews. We don’t run ads, so we don’t worry about advertisers being annoyed.
We are continually improving.
We are always looking for ways to improve, from designing a unique test for portable devices inside a car to upgrading to the PurpleAir Zen air quality sensor. If you want to suggest units we should test or have any other feedback for us, just message us or join our community on Reddit.
