Tangent: HEPA filters are one of the best QoL investments you can make. You should start caring about what you breathe right now if you don’t already. WHO recently tightened PM2.5 guidance closer to zero and all the evidence so far is that the more we learn about PM1 and finer pollution, the more horrifying the health effects.
HEPA really isn’t good, the way hepa filters are manufactured and discarded is really bad for the environment. A better alternative is electro static and ionizing filters that are cleanable, like airdog provides. The tech isn’t new, but the industry isn’t interested in not making money on disposable hepa filters..

Wasn’t the issue with the ionizing filters the production of ozone? I recall that being the reason the Ionic Breeze units fell out of favor.

Wasn’t the issue with the ionizing filters the production of ozone? I recall that being the reason the Ionic Breeze units fell out of favor. How is Airdog any different?
Smaller Ionizers release really small amounts of ozone, airdog isn’t mainly using ionizing, the bigger filter is the electrostatic one. Ozone machines are dangerous though, but it’s no secret. You really shouldn’t use any ionizer in a non ventilated space for a long time though, it will build up
If you haven’t, you owe it to yourself to try merino wool shirts. Check to make sure you get just the 100% wool models, most brands have pure and blends.
I tried five different brands, from $40 to $120; only one was decently comfortable (most were itchy, stretched weirdly and were uncomfortable) and the extra burden of washing and maintenance, not to mention cost, made them a non-starter.
For $5 a shirt, Gildan 100% cotton v-neck t-shirts allow you to buy a couple dozen and rotate through them for years.
That's where I'm currently at, I wanted to love wool, but I just didn't. I've had it on my list to give linen a shot.

Any brand recommendations?
Outlier makes expensive but very nice wool tshirts. I have accumulated a fair number over the years and only see issues with the ones that are over seven years old.
All of the sudden articles about the negatives of textile fabrics in the last 3 days feels like a Paul graham style submarine.
Don't assume an agenda, you also had a very positive spin on tech fibers in another thread yesterday [0], perhaps OP felt like we could benefit from an opposing view.
If anything out of scale alone the collective of cotton/wool/linen producers will likely have a lot less lobbying power than the industry around petro-chemical fibers.

Ionizing air filter are a health hazard on their own: https://pubs.acs.org/doi/10.1021/acs.est.1c02582# I don’t know input HEPA production, but if you throw them into household trash here in Germany they simply get burned.
From the article, there doesn't seem to be much of a conclusion rather than more studies are needed, since the technology is poorly understood. And I agree, the idea is that ionization happens naturally, it does, especially after lightning strikes, which then pulls particles downwards to the ground and nearby objects, the same happens indoor. This is good, particles The problem with HEPA filters are the destruction of resources to make them, the bad controls of their quality and their short lifespan (Cheap home HEPA filter needs exchanging every 3 months) and their high price (>30€).
