I’d like to get one that has widely available filters and would prefer to spend less than $250 as much as I would like a Dyson one. It’s only for an apartment so I don’t think I need something massive but I do live above a busy road.

  • Don’t waste your money on anything that doesn’t have a HEPA filter, that’s the golden standard.

    Make sure you’re doing a bit of math on how much air purifying power you need, what works for a 100 sq ft room with an 8 ft ceiling is going to be insufficient in a 400 sq ft room with a 10 ft ceiling.

    Fortunately, someone has made a nice calculator for that here.

    Winix and Honeywell have been good brands in my experience.

    • HEPA filters may not be necessary - it seems that homemade air purifiers with standard filters can outperform them in clean air delivery rate, arguably the most important factor for a purifier. The air may not be as clean with each pass through it, but it’ll move much more air.
