HouseFresh is an independent website about air quality.
Founded at the end of 2020, HouseFresh is a small team committed to helping people breathe clean air without being duped into buying overpriced and underperforming products that don’t live up to the marketing hype.
That’s why we don’t just look at lab reports and product specs from marketing materials. Instead, we buy the products ourselves and run experiments in a controlled home environment to gather real performance data.
But we don’t just stop there.
To help our readers find a long-term solution for their indoor air quality issues, we also share how-to advice about common air pollutants and release original studies into the state of clean air worldwide.

How we test air purifiers
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 recommending 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 ozone levels 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 test room, 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.
1. In our 728-cubic-feet test room, we light an incense stick to generate particle pollution. We then set up our PurpleAir Zen particle counter sensor to track levels of PM1, PM2.5 and PM10 in the air.
2. Next, we switch the air purifier and access our dashboard remotely to keep track of PM1 levels based on data from our PurpleAir sensor. The test ends when PM1 levels reaches 0. We repeat this at each fan speed.
3. We set up an energy meter and a commercial sound meter in our basement to measure the electricity consumption and sound levels generated when running the device at each fan speed setting.
4. We visualize all the data from our tests in graphs like this one to compare the device against other units at the same price point or with similar air cleaning performance.
5. We estimate CADR figures for the device at different fan speeds taking into account the particle removal rate of the device in relation to the natural ventilation of our test room:
6. We calculate an overall score for the device that incorporates first-hand data, as well as our ratings for customer service, brand transparency and design & UX.
How we make money
We only get paid when our readers buy a product we recommend using one of the links provided in our articles. At no extra cost to you, the retailer you buy from will give us a 3% commission on the value of the device you purchased.
These affiliate commissions are our only source of revenue. We don’t take money in exchange for sponsored articles, we don’t accept compensation in exchange for glowing product reviews, and we don’t monetize our visitors with ads on the site.
HouseFresh is a fiercely independent publication with no back-door deals with any of the manufacturers and brands we feature. We know that we will only continue to exist if readers like yourself trust our advice, so we don’t want to tarnish our reputation as honest independent product testers just to make a few ad-fueled bucks.
Our reviews and thorough testing take many weeks of work, so if you want to support our work but don’t need an air purifier right now, you can just buy us a coffee or support us by choosing one of our clean air t-shirts.
Real product reviews take a lot of work
We invest weeks into testing each device to assess whether real-life performance aligns with the manufacturer’s claims. Every review we publish is backed by data and multiple hours of research and first-hand testing.
We try to produce the type of reviews we wish were more prevalent on the internet. That’s why we dig deep and gather comparable data on every product so we can tell you whether the device is truly worth your money or if there’s a better option out there.
If you are a fan of our work, 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.
