If you want to know what Google-Zero is, the Verge did a podcast on it last year referencing @housefresh.bsky.social and other independent website owners about what happens when Google doesn't actually refer viewers to your website, but instead scrapes your content and pushes AI overview and spam.

According to major publishers like Wirecutter, CNET, Good Housekeeping and Forbes, the 311i Max is one of the best air purifiers on the market today. But does it actually perform? Danny shares what our data has to say. youtu.be/3YLGt7DUdac

🏆 The Blast Mini was named the best classroom air purifier in the UK by @housefresh.bsky.social & @safeairschoolsuk.bsky.social. Tested against 13 models, it stood out for strong performance, low noise & running costs, making it a top pick for classrooms. Read more: bit.ly/3H8qI89

Are you worried about AI turning us into mushy-brained monsters, draining resources, slurping your data, preying on vulnerable minds, wiping out jobs, choking websites, lying to you or not being useful? @shiraovide.bsky.social explains how to turn it off in search results: wapo.st/4712tmO

Someone bought 300+ spam links and pointed them to one of our most critical air purifier reviews. The first wave came after we sent a request to the brand for comment about a new product. The second wave came the day after @linusmediagroup.com posted a video about the brand threatening to sue us.

Whew: a reminder how shockingly unreliable Google AI overviews are (and to some degree, anything AI offers as ‘knowledge’?) - it seems they're taking blurb from press releases, sponsored posts and products listings and offering it up as “facts”: housefresh.com/beware-of-th... (via @ernie.tedium.co).

What if you couldn't trust any review on the internet? What if EVERYONE was being controlled by the companies that make those products? WELL that might be what is happening… YouTube Channel HouseFresh is facing legal backlash over publishing an honest review for a PuroAir 240. youtu.be/RNonfByE9xc

We spent weeks researching air purifiers we reviewed to determine whether Google Search results and AI Overviews are leading consumers to good advice. Our analysis shows that AIO will likely recommend buying whatever you show interest in, even if the product doesn’t exist.

There is a lot of money to be made at a time when Google’s algorithm opts for the ‘goog enough’ approach. Here are some practical tips to find helpful product reviews in a sea of crappy listicles 👇 www.reddit.com/r/HouseFresh...

“Google is drowning the very recommendations searchers are trying to find while surfacing generic best-of lists, 2016 Quora advice and SO MANY products — many of which SUCK and don’t even meet the search criteria,” wrote HouseFresh managing editor Gisele Navarro. tinyurl.com/26p8j985

Running HouseFresh has been an uphill battle. First, we had to fight for independent websites like ours to still show up on Google. Then, we had to fight for our critical product reviews to stay online. In this video, we share the full story: youtu.be/RNonfByE9xc

What to look for in a commercial HEPA filter. It's not easy to compare machines. A few key considerations: 1. CADR 2. Noise 3. Filter grade 4. Cost 5. Hidden extras / tech 6. Replacement filters 7. Auto mode 9. Carbon filter 10. Final thoughts 11. Resources & tweets 1/🧵

This is why we need to limit children's #AirPollution exposure with measures like #SchoolStreets, phasing out #WoodBurning and reducing the number of vehicles on our roads overall. Even brief exposure to high concentrations of particulate matter (PM) may impair a person’s cognitive abilities 👇 .

Our review of the Tempest Euro by @nukit.bsky.social is live: 💨 It cleaned our 728 ft³ test room in 27 minutes — faster than the Alen 45i, Dyson Big+Quiet BP06, Mila and Coway Airmega 150. 💰 It has the lowest yearly running costs we’ve seen at $44.23. ▶️ youtu.be/ZjGJN57DgA8

Plot twist: The websites of small businesses featured in Gemini AI ads are penalized by the next Google algorithm update. Google hosts a Small Business Web Creator Summit to tell the owners that it wasn’t their fault, and that Google needs to do better at rewarding their Gemini AI content.

This is important info 👇 If you bought an off-the-shelf HEPA filter, you need to check if you're getting the right level of air filtration out of it.

With wildfires raging in California, we noticed that some manufacturers are advertising their small air purifiers as great options for dealing with wildfire smoke. However, most small air purifiers will be useless against wildfire smoke. Here is what you need to know 🧵

The Blast Mini is 🥇 for high CADR based on independent tests of 94 air purufiers: housefresh.com/high-cadr-ai... Thanks @housefresh.bsky.social

Is now a good time to mention that last month over 25 Los Angeles schools rejected our offers of completely free air purifiers for every single classroom on their campuses?

If you live in an area affected by wildfire smoke and can’t afford to buy an air purifier, please consider building a Corsi–Rosenthal Box as you might have all the components at home already. Here's what you need + how to do it:
