how we can clean air surrounding us

Hi, I just read your question. Having Bronchiectasis, I have blueair purifiers in all of the rooms I spend the most time in. If you want to see if it’s an item that can help you, here’s one resource. There are others:
BLUEAIR Air Purifiers for Large Rooms, Cleans 3,048 Sqft In One Hour, HEPASilent Smart Air Cleaner For Home, Pets, Allergies, Virus, Dust, Mold, Smoke - Blue Pure 211i Max

I have a large Austin Air cleaner in my bedroom. They are easier to maintain than some and do a lot! I own my condo and its furnace and have a UV light on the furnace that cleans the air in the air ducts- after having them cleaned. That light was processionally installed for that purpose and will last a few years before needing that bulb replaced. I also sleep using a BiPap which filters the air ( for sleep apnea). But I'm a bit of a fanatic when it comes to air and water.....

Hello we live in an area with usually high pollen and frequent smoke. We have a HEPA air purifier on our furnace and 2 Honeywell HEPA room air filters-one in our main open living space and the other in our bedroom. We chose Honeywell for the easy availability of filters and ease of changing. Due to our air, I change the charcoal outer filter about every 6 or 8 weeks and the HEPA ones every 3 months. These have run for over 5 years completely trouble free.
