I wish rtings had a Boolean on tvs so we could search explicitly for non smart models. That is basically the only thing else I’d want from that site, it’s really good.

I think the main problem is probably finding any mainstream consumer TVs that are non-smart. I have looked and beyond some obscure brands or short of incredibly expensive commercial models there are barely any options.

Any TV is stupid if you don’t connect it to the Internet.

The Wirecutter is a highly flawed review site, but at least it's a real one. There are vanishingly few left for general consumer products. There's WC, Consumer Reports, and what else? They've seem to have all been killed off. When I'm researching some category of product, I feel lucky if I find any professional reviews written by people who have actually touched the thing they're reviewing. I know we've all had the e…

I feel like the crowd-sourcing / SEOing / optimization of reviews on the internet has, for all its benefits, made everything too noisy and untrustworthy. I know myself and a lot of other people first search reddit now instead of google because it's impossible to get anything written by a real nonbiased human otherwise. For similar reasons I've used things like Yelp less and less and tried to use professionally editor…

Heh. The biggest problem I have with Amazon isn't even the fake reviews, it's the people who leave reviews and don't even know what a review is, which is almost all of them.

Why? It's a 0.05% difference, seems pretty small to me.

The difference between 99.5% and 99.95 is the difference between an event happening 1 in 200 times and happening and 1 in 2000 times. It's a 10x difference. The author's "I'll just times .1 by the percent of flow, and produce very small numbers that look fine! See! The numbers are so small!" trick is just … wrong. The author implies that the difference can be made up by the volume of air being processed, but that wou…

Probabilities and amounts are not comparable even though they both use % notation.

In this case they are measuring the % of particles captured (an amount), not the likelihood a particle is captured (a probability). The parent is right, it’s a tiny difference.

The author explicitly states that it's small in the home use context. If you're talking about medical or cleanroom manufacturing contexts, yes it's a huge difference.

Small home or not, homes are not sealed environments. A 10x difference is a 10x difference. Using one small number or produce another small number, so the difference looks small, doesn't hide the 10x change.

How is there a 10x change? I see a 0.1% change.

0.90005 times 10 is 9.0005, not 0.9005 (I.e. the two fractions presented are 90.005% and 90.05%). Even if you look at the complement you get 9.995% vs 9.95% which is small. One could imagine that these differences could also arise from eg obstructions to airflow or positioning in the room or the direction of the wind outside. The point is that the difference is dominated by air flow in a typical environment rather than filtering differences.

In the UK, https://www.which.co.uk/ fills a similar niche to Consumer Reports.

I used to subscribe to Consumer Reports back in the day, and basically regretted it. They rarely described their testing methodologies and more often than now, when they did, I wasn't impressed. Their testing usually just boiled down to whether or not the specs met the manufacturers claims, not anything useful like how well it was built and how long it is likely to last.

Protip: you can turn a box fan into an incredibly effective air purifier[0] (particle measurements in thread). The one they show is pretty elaborate, using 4 filters and some construction, but you can also use a single filter and slap it on the back of the box fan and have similar results. The air purifier industry is more about aesthetics than it is function. 0. https://twitter.com/LazarusLong13/status/1425517352624…

Thank you. This is amazing. Precisely what I've been searching for. Something cheap, affordable, and most of all, moves a large quantity of air within a short amount of time. Loudness doesn't bother me one bit since I almost always have white noise playing in the background.

It will be interesting if LMG can pull off what Linus is aiming for with the massive investment in a laboratory environment. There are huge parts of the tech market where the most critical reviewing you can find is anecdotal accounts of if the reviewer liked a product or not (or the more clinical reviews are drowned out by the anecdotal noise).

Phones and anything Apple are reviewed to oblivion. There are some incredible consumer product review YouTube channels out there too.. The Best one imo is project farm ( https://m.youtube.com/watch?v=vO3UX4oEnZI ). If you're into headphones, Crinacle's site/YT are on a completely different level than any other review site I really hope LMG does videos in these styles with their lab

I believe their intention with the lab is to focus more on written articles instead of video content? He’s complained on his podcast (in the context of talking about the lab) about the decrease in quality print journalism in the tech space.

This is definitely not a conspiracy theory. Incentives affect reviews, which is why truly unbiased review sources exist.

Especially when they already have a proven track record of nastiness: https://www.xdesk.com/wirecutter-standing-desk-review-pay-to...

Oh wow! I hadn't seen this. Thanks for sharing.

There might be better air purifiers, but the recommended Coway purifier is really good. I've had one for 5 years, still working as well as the day I bought it. I also have a 3x more expensive high-end Alen unit, but it's not nearly as effective or quiet as the simple Coway. The filters are way more expensive too.

Same. The Coway is very quiet, and it works rather well, as measured by the Dylos particle counter elsewhere in the room.

I have four of them to cover both floors of a two-story house. They work well (so long as you remember to clean the prefilter every month or two!) and are very quiet on the lower fan speeds.

The only thing I'd ding them for is not having a fan speed setting in between "nearly silent" and "jet engine", but you should only need the highest setting in unusual circumstances.
