HouseFresh is an independent publication focused on air quality.
We offer advice on how to tackle air pollutants in the home through how-to guides, product reviews, practical tips and original research on a variety of factors that affect indoor air quality.
Our team comprises indoor air quality experts whose ultimate goal is to help consumers air quality products that don’t live up to the marketing hype.
We are committed to finding the perfect device to improve your home’s indoor air quality long-term. That’s why we don’t just look at lab reports and product specifications provided by manufacturers.
We buy all the products with our own money and run our own experiments in a controlled home environment to understand the actual performance you can expect in your home. Our reviews dive deep into a product with tests designed to assess the product’s capabilities, energy usage, long-term costs, and sound generated.

How we make money
HouseFresh only gets paid when our readers buy a product we recommend. At no extra cost to you, the retailer you buy from will give us a % of the sale. We are a fiercely independent publication with no relationships with any of the brands we feature, and we don’t allow adverts. Our reviews and in-house testing take many hours of work, and we continually reinvest the money we receive into new in-depth product reviews.
How we test each product
We want our product reviews to be more than just a matter of personal preference or, even worse, the same repeated marketing slogans that every other site reviewing air purifiers will publish.
Danny, our founder, has been writing about air purifier technology for over a decade when most websites promoted ionizers that we later found emit dangerous levels of ozone just because they were selling well online. We don’t want to repeat that story. That is why we actually test every product we recommend in our own home lab, in addition to conducting hours of research into the different manufacturers and the technologies behind each product.
Our in-depth performance testing allows us to directly compare different models (and even different technologies) like for like because every product is tested performing the exact same jobs in the exact same space.
- In our home lab of 728 cubic ft, we light an incense stick to generate particle pollution and VOCs.
- We set up our trusted Purpleair Indoor Sensor with the latest Bosch gas sensor to track levels of PM1ug/m3, PM2.5ug/m3 and PM10ug/m3 and VOCs in the air.
- We switch the air purifier to its highest speed and measure how long it takes to get our room air quality down to PM1 level to 0.
- For portable air purifiers, we repeat this test inside our Tesla Model 3 to see how good the unit is at cleaning the air in a small enclosed space.
- We use an energy meter to measure precisely how much electricity is used when running the unit at the lowest and highest fan speed settings.
- We track sound levels emitted by the air purifier at different fan speeds with the help of a commercial sound meter.
We share all the data we generate from our performance tests and include them as a download as part of our Flourish data graphs like this one:
Real product reviews take a lot of work from a lot of people
Before we publish a review here at HouseFresh, we invest a ton of time to truly test each device and understand exactly how it will perform in the short and long term. Every decision we make is backed by data and many hours of research and first-hand testing.
We try to create the type of reviews we wish were more prevalent on the internet by doing the hard work it takes to dig deep, truly evaluating performance compared to other products. You may see only 15 people on this about page, but our team is much larger than that — there are 24 of us in total, working in the background to make HouseFresh possible.
Check out our reviews and let us know if they meet your expectations. If you are a fan, please let other people know about HouseFresh. Your support will allow us to produce even more in-depth reviews, buying guides, how-to articles and original data studies in the future.
Our goal is to be a source of truth for those who are looking to improve the air quality in their homes, regardless of where they are visiting our site from.
