Can anyone provide or link to some solid guidelines on what kind/brand of air purifiers actually do real effective filtration vs. garbage products? I have found that a great many of these "air purifiers" have great marketing and make amazing claims.

I’ve been happy with Austin Air purifiers. Most of the other brands help, but don’t handle most VOCs. If you have allergies or other issues, it’s better to stick with top quality brands. https://housefresh.com/austin-air-healthmate/ https://housefresh.com/austin-air-healthmate/

A 20” box fan and 4 20” furnace filters

  Unless you live in a place with very cheap electricity, you'll save money in the long run by getting a purpose built air purifier

    How much money over how much time?
    - Rebelgecko 2y ago
      It depends on the box fan and your electricity prices. When I did the math for me, the break even point for buying a $150 purifier was on the order of months. But I'm in California where electricity is relatively expensive

    nothing comes close to crbox in terms of performance... the gold standard IQAir do give you close to perfect single pass filtration but the cfm is so low and noise much higher...

  Yup. We have several of these running. Helps with allergies and when one of us got COVID the rest did not. https://en.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box https://en.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box

Basically all filters work l, they just need to be big enough. The largest air purifier from Xiaomi is okay, ones from ikea are a little small but nicely made
