InSight HEPA Tower HPA180B

Have the honeywell 1800 series. Works well, just the filters replacements are difficult to find here (Canada). I have the feeling I will eventually pay 3x the machine price because of how ofter I need to replace the filters because my neighbours smoke leaching into my condo.

Honeywell we use the big 500 sq foot one for main floor and the smaller 200 sq ft one for the bedroom leave them on low change filters every 4/6 months

I love the ugly-ass Honeywell tower one i have. You can get washable filters too, which is a nice money saver. It's relatively quiet and powerful. Everyone should make at least one Corsi-Rosenthal box though because they are super effective!

I have a huge Honeywell tower that I loved for my old studio apartment, but now that I’m in a large house I honestly think corsi-Rosenthal is the best bang for your buck. They’re incredibly effective, cheap, good for large spaces, and customizable.

Yes. I have Honeywell HEPA units in multiple houses. 24/7.

Yes, an air purifier helps. The best brand is Honeywell with a HEPA filter. Second is Bionaire with True HEPA filter (purple one), third is Bionaire with the blue filter. Levoit kind of sucks. Don't waste your money on the Pure Enrichment Personal Air Purifier.

Honeywell. Their HEPA air purifiers routinely test out as the most effective and they make units made for spaces that large (I have one, it's such a relief during wildfire season). They aren't the quietist or the prettiest, but they don't need to be because they work. If you'll allow me on my soap box just a sec, please don't spend your money on popular "technologies" like ozone, static electricity, magnetized, etc. They don't work. What works is certified HEPA filters, H13 or H14.
