In a bid to replace falling ad revenue, big media publishers are inundating the web with bad product recommendations you can’t trust.
Google is killing independent sites like ours through inaction.
We hope to still be here to see things change:

H13 filters are typically used in laminar-flow air purification equipment—more precisely, laminar-flow supply devices such as FFUs and laminar-flow hoods. Such equipment does not rely on recirculating filtration; instead, it delivers a single pass of extremely clean air to create a localized clean zone. It is mainly used in cleanrooms, hospital operating rooms, pharmaceutical production lines, and biosafety laboratories. For residential air purifiers that use recirculating filtration, H13 filters are unsuitable because their high resistance actually reduces CADR. Unfortunately, after more than a decade of commercial marketing, the idea that “the higher the filter rating, the better” has become deeply ingrained in consumers’ minds. Through repeated testing, I have found that EPA11–12 filters can provide the highest CADR in most air purifiers—though this also depends to some extent on the fan’s airflow-versus-resistance curve.

This brilliant ad summarizes our mission statement, make devices that can be repaired, upgraded and don't rely on proprietary components that lock you in. Maybe not the best business strategy but we're not really "business" people:

Came across this image a while ago from @housefresh whilst doomscrolling and felt it was important to share.
Using 2024 PM2.5 data, it estimates the cigarette equivalent air pollution exposure across 20 UK cities. A powerful reminder that cleaner air matters.
#AirQuality
ALT Infographic titled “The 20 UK Cities Where You’re Indirectly Smoking the Most Cigarettes.” It explains that cities with higher average PM2.5 air pollution are associated with more cigarette-equivalent exposure. Liverpool ranks first, with 171 cigarettes per year, followed by Worthing (166), Northampton (158), Manchester (149), Bournemouth (148), Ipswich (146), Bolton (133), Kingston upon Hull (131), Swansea (131), Cardiff (131), London (129), Nottingham (129), Luton (128), Portsmouth (126), Bristol (124), Plymouth (123), Sheffield (123), York (123), Belfast (121), and Birmingham (121). The graphic notes that the figures are based on 2024 PM2.5 data and Berkeley Earth’s calculation of cigarette-equivalent exposure. An illustration of lungs and smoke appears at the top right.

Picture this:
Google’s algorithm updates have been slowly killing your long-standing food blog year after year.
No matter what you do, traffic from search keeps dropping so you decide to sell the domain to the highest bidder.
They tell you their company has a “commitment to high editorial standards” and “honest information,” so you trust that your hobbyist website will be in good hands.
Soon after, the weird self-help AI slop articles start appearing.
Your site was about vegan food but somehow they are now publishing stories about how “psychology says the loneliest people in life aren’t the ones nobody likes — they’re the kind, helpful people everyone appreciates but nobody thinks to check on.”
Your blog is now another AI slop zombie website being farmed for Google Discovery traffic and ad money.
Welcome to the content farm ↓
NEW: Brown Brothers Media is the most successful media company you've never heard of. Its success was fueled by AI, fake writers, and fake reporting.
When we started asking questions, BBM started mass-deleting content. What it became next was even worse.

Now that kids are back at school, and autumn is coming, airborne illnesses are going to spread through schools.
Will you write to your MP to ask them to support putting air filters in all classrooms, please.
You can download a template letter here...

We've shipped air purifiers across Canada and I've had nothing but wonderful interactions with our fellow citizens. We will overcome this attack on our nation by sticking together and building on our strengths. #buycanadian #airpurifier #airquality

r/Dehumidifiers is no more.
The subreddit was full of advice and first hand experiences, so it's a big loss for the web.
We've been testing dehumidifiers for a while now -- 31 models so far! So if you have questions about dehumidifiers, head over to teddit.net/r/HouseFresh/

Quoting CADR without the corresponding noise level is like quoting someone's running time without saying whether it was for 800m, 1000m, or a mile—the number alone means nothing. and you need to compare apples to apples.

By NEXT WEEK you can do something that results in less sickness for everyone in a classroom. Improving air quality = less illness spread. Adding 1-2 purifiers in classrooms can drastically reduce how many students (teachers & their families) become sick this school year.

This is happening to websites in every corner of the internet.
Google AI Overviews may be convenient for the searcher, but this convenience comes at a cost.
Sites like HouseFresh and Inspired Taste are powered by real people who spend real money and real time to create valuable content for the web.
We won't be able to survive if every Tech Giant keeps training their AI with our work without compensation just to sell convenience to their users.
If this continues, the information your AI of choice will offer you in a few years time is bound to be a mix of advertising, spam and old content from the days when websites were still alive.
Here is the day that Google decided it knew how to cook everything👇
In November 2025 Google started consistently showing AIOs for all "how to" recipe queries, ranging from easier to very complex recipes...literally everything!
We worked hard to perfect these recipes by testing them countless times and responding to thousands of comments over the past decade.
Then Google steals our recipe, photos, videos, and misrepresents our content in mangled AIOs that compete against us in position one. This isn’t “commodity” content @rajanpatel and @rmstein.
We along with countless other recipe sites helped train the Google models. We perfected the recipes that Google stole by being human and doing all of the hard work. We purchased the groceries. We hired a chef. We filmed the videos. We maintained the recipes. We built something out of nothing. Google did nothing but steal everything. Look at the traffic loss👇👀
Google simply can’t do this to the open web and expect it to continue to train the AI models without compensation. Google is destroying Google search by doing this. If publishers are out of business Google won’t have anything to train on.
We are easily seeing 50-70% drops in clicks for these queries. These how to queries represent only a fraction of the drops we are seeing. This is insane and completely unsustainable!

Google wiped out 99% of our traffic at Gamers Heroes.
Every guide hand written, with first hand experience, by one of us.
What takes its place? Content farms who spit out 10x the content because they just rewrite guides from other websites 😆
And if its not that, its AI doing exactly the same thing but with a microscopic link nobody wants to click.
Not sure it will matter much in the long run. I feel like publishers will have "AI do this for me" for whenever players get stuck

Air quality is one of the most overlooked factors in creating a healthy learning environment. There is a question we should be asking: What are our children breathing while they are at school?

What Google used to say about helping creators succeed online VS what Google says now:
Google attorneys repeatedly characterized AI Overviews as a “product improvement” and called the historic traffic-for-crawling bargain with publishers a “vague historical course of dealing.”!!! GTFO. Mehta pushed back: the situation “all seems really unfair.” 2/5
