Honeywell - HPA710

They aren't as advanced as others but I like the Honeywell air purifiers, and the Insight series can take a secondary filter for specific things like dog hair or VOCs or even tobacco smoke. They are cheaper to buy than other smaller brands but my first one has lasted I think 7 years maybe or so. Same with my HomeLabs dehumidifier. Never expected that to be the case for $100ish each. If I shine a flashlight I see practically zero dust in the air and can easily see what the charcoal filter grabs in front of the HEPA. Best buy had the https://www.bestbuy.com/site/sku/6412406.p?skuId=6412406&sb_share_source=PDP On sale for $99 recently. The 500sq foot room model is only $169 when it details for close to $379. https://www.bestbuy.com/site/sku/6412444.p?skuId=6412444&sb_share_source=PDP Not sure for your car though.

My daughter is allergic to a lot of things like dust and pollen. We got two Honeywell HPA710 air purifiers, and she has had a lot less issues since. They're always set to auto, and it doesn't take much to get them to increase their purifying power. On a day with lots of pollen, just opening the front door or a window can set one or both of them off, so they're definitely doing what they're supposed to. Yes, those purifiers and replacement filters aren't cheap, but your health is worth more than other things.

I bought some Purrit ionizing purifiers on IndieGogo. They do produce some ozone, but if their marketing paperwork is to be believed it's well below the legally permitted amount.

I use the large room honeywell air purifiers. The one I have now has been running 24/7 for the last 5 years or so and is still trucking along. I use it because my wife and son smoke weed and smoke bothers me. It does a good job getting rid of the smoke and the amount of crap that is on the filter is amazing. I pretty much never have to dust.

I live in a tall loft with ciment ceilings and it produces a lot of dust. I got a large Honeywell HEPA air purifier and it works very well. The carbon pre-filter can be vacuumed and there is a thick layer of hair and dust every week. The inner filters I vacuum every month and change them once a year.

Just stay away from the Honeywell HPA models. They all develop a burning smell. I've swapped my 2 out a total of 6 times.
