Musty basement odors are usually a moisture issue, whether it's condensation, minor seepage, or just consistently high humidity.

Neighbor smoking weed

Hi! Best way to keep your apartment smelling fresh is a air purifier. I use Blueair 311i max. It covers over 3000sq ft. I’m in a 1000sqft apartment and the overkill on purifying is worth it.

To buy air purifiers or not

Thank you for the very detailed response. Very sorry to hear about your experience. I appreciate the recommendation but I have to consider looks. It’s just who I am, and I wouldn’t enjoy having the typical air purifier, looks wise. I heard about the ionizer in Blueair as well, and did some research.

Need advice for my first air purifier

https://www.blueair.com/products/blue-pure-311i-max On sale at the Blueair website and I find Blueair purifiers to be excellent. Just make sure you get the smoke/carbon filter if odors are also a concern.
