I've tried doing my own research but I've become so overwhelmed in trying to pick the best and most effective air purifiers for each rooms. I feel so lost.

1. I need 4 air purifiers that handle dust, pollen, and odor(VOCS?).
2. Without an ozone option would be best. We have small pets and seniors who like pressing buttons... I don't want any accidents of turning it on.
3. Overall budget for 4 air purifiers is around $600-$700USD total.

Sizes of each room are approximate. Estimated up since I'd rather have something "overpowered."

Bedroom 1: 175sqft
Bedroom 2: 250sqft
Living room, kitchen, dining room combined (open concept): 900sqft
Fourth space: 175sqft

All knowledge and advice is appreciated.

My older Bissell vacuum seems like it's not doing enough, so I'm looking for something else. Something that will trap dust and not just spread it around, durable and preferably lightweight, but I understand if that's not an option.

Around 2000sqft house, about 90% carpet, 10% hardwood floors.
Hair, dust, allergies, and pets, we have it all.
Budget: $500, as long as it doesn't break within 5 years.

I was eyeing a Miele, but I wanted to know if there's anything else out there.
