We built a free, data-driven tool to objectively help you choose the right air purifier for your home. There is so much marketing noise in the air purifier space. Companies use and come up with all sorts of buzzwords to suggest that their purifier does something special. It's shockingly difficult to get straight answers and objectively evaluate performance. So we created a free tool to help you pick the right air purifiers for your home. 100% free, no signup required, no affiliate links, no partnerships or bias. Just data. Here’s something that might surprise you: most modern air purifiers filter about the same percentage of particles. Any HEPA filter removes at least 99.97% of particles at around the size it performs worst at (which is pretty dang good!). So what matters more is throughput (measured as CADR, or Clean Air Delivery Rate), how much air the unit can push through that filter. A purifier that's too small for your room will never get the air clean, no matter how good the filter is. But after consulting on air filtration with a lot of clients, we've realized that there are some other real-world, practical considerations that most recommendations ignore: > Quiet matters. If an air purifier is too loud, people simply won't use it. And an unused air purifier is no good at all. > Ease matters. If you have to replace the filters too often, most people will simply not do it. And dirty filters tank the efficacy of a unit. > Beauty matters. For many customers, having an ugly air purifier is a non-starter. So finding aesthetically-appealing ones, at least for certain rooms, is a factor. > Price matters. On top of all that, people want value. If it's too expensive, it won't get purchased in the first place. So we've created a tool that factors in all of the above to recommend the right air purifiers for your home. You put in your room sizes and preferences around noise and design, and it recommends a best-value pick and an upgrade pick for each room. The site walks through the methodology behind it all, including a metric we developed called "Quiet CADR," the clean air delivery rate at a volume you can actually live with. One of our main goals at Lightwork is to bring science-backed, data-driven rigor to the home health industry, which has historically been plagued with imprecision, poorly-supported claims, and (at worst) scams.

We tested @awilkinson's house. He's as health-conscious as they come (and his house was top tier). But we still found room for improvement. In his recap, he said: "I've talked to a bunch of friends about this. The ones who've gotten their homes tested all have the same thought: 'It's insane that nobody checks this stuff.'"

Unregulated disinfection byproducts are a major source of drinking water toxicity that nobody is testing for (apart from us!). Researchers conducted a comprehensive investigation into U.S. drinking water toxicity and found that unregulated disinfection byproducts (DBPs) are key contributors to overall toxicity. DBPs form when disinfectants like chlorine or chloramine react with organic matter during water treatment. In the US, only 11 DBPs are currently regulated, specifically some trihalomethanes (THMs) and haloacetic acids (HAAs). However, thousands of DBPs can be created through this process, and most are not routinely monitored or tested for. This research found that many of these unregulated DBPs are significantly more cytotoxic and genotoxic than the regulated ones, and they occur just as frequently, if not more so. Why This Matters Many highly toxic yet unregulated disinfection byproducts are effectively overlooked by standard water testing, despite contributing meaningfully to overall drinking water toxicity. While there has been a strong focus on PFAS contamination in recent years, DBPs are typically found at concentrations more than 1,000 times higher in drinking water, making them a much larger concern for most homes. That’s why we now offer an advanced water test that measures the total amount of these sorts of disinfectation byproducts in your water, capturing the combined impact of all the regulated and unregulated disinfection byproducts so we can assess overall risk and guide targeted contaminant reduction and any further testing.

We recently ran our full environmental health assessment on the @superpower HQ and @maxmarchione's personal home. Are they as healthy as they claim?" Most people track their sleep, dial in nutrition, and fine-tune supplements. But they overlook the spaces they spend most of their time in: their home and office. And more often than not, those spaces are working against them. Air quality, lighting, water purity, EMF exposure, and mold are all critical factors that can influence sleep quality, focus, hormone health, recovery, and more. Tomorrow we're sharing everything live: the full results, plus actionable steps to optimize your own space. What you'll learn: > The real findings from Superpower HQ and Max's home, fully unfiltered > The hidden environmental factors that hurt performance and longevity > The highest-impact fixes for air, water, light, and EMF exposure you can implement immediately Everyone who registers is entered to win a one-year Superpower membership plus a full water lab test for 100+ contaminants with a consultation.

We tested @derekflanz 's home in Austin a couple of weeks ago, and he wrote about the experience in his 5 Healthy-ish Things newsletter. One of the main findings was elevated AC electrical fields in both of his daughters’ rooms and his wife’s office, which we’re now helping him resolve. It’s a great behind-the-scenes look at a Lightwork assessment.

We just wrapped a workshop for @jonnym1ller's Nervous System Mastery cohort on how your home environment impacts your nervous system and overall health, and what you can do about it. We explored EMFs, air quality, ventilation, mold, water quality, and light - the core inputs that quietly shape how your body feels, sleeps, and recovers each day. At Lightwork, we believe that creating a healthy home is one of the highest-leverage things you can do to improve your health.
