Unlimited Budget to Remove Odors
You may want to investigate a whole house air filtration system if you indeed have the budget. Otherwise your options are basically something like AirPura, it filters both air and uses large amounts of carbon to get rid of smells.. https://www.airpura.com/ An alternative would be something like the

PC fan purifiers vs HEPA for allergies
I have the 75i which is rated 351 cfm for dust, luggables Xl-7 Ultra is 401 dust, and 450 pollen. I'm happy with both of them. Alen says either 7-10 months for carbon filters or 12-15 Mos for the pure hepa. I've owned for 3 mos and the indicator shows nearly 50% used. If that's the case it's not goo

Anyone with experience with alen air purifiers.

Best Air Purifier for Neighbor's Weed
Look at creating positive pressure - easiest way is a fan in a window blowing air inwards. This should be your first plan of attack imo. As for purifiers, you’ll want the most carbon you can get. For your budget look at Alen 75i + their VOC filter. There are others with more carbon but they’re $$$$.

Top Air Purifier Recommendations to Elevate Your Coffee Shop Experience
If you want to buy off the shelf: Alen 75i (or two) with their VOC filter. Should be right on budget. Although I do believe they have commercial units as well. Check their website for commercial pricing.

Alen 45(or 75) Vs Allerair Med 1
Re: dust, this is frequently asked. Air purifiers aren't good at removing visible dust as it's large and heavy compared to something like PM10, PM2.5, or PM0.1. See the sticky post at the top of this subreddit and our FAQs wiki page entries: I need an air purifier for dust. What should I buy? Why is

First air purifier purchase
Ideally, you should have a ducted range hood that exhausts to the outdoors. Cooking pollutants (including odors) are best handled via exhaust ventilation. See our FAQs wiki page entry "Which purifier should I buy to control cooking particulates or odors?". Are you looking to remove chimney smoke par
