Hello! I am considering what types of air filters might be good for my new office, as the building doesn't have great ventilation and my window can't open. The office is about 12x15ft

These are two I'm currently considering:
cowaymega.com/products/airmega-250?srsltid=AfmBOooIrMRKeVrUPS1ZDSeFAWQ3fZik2_i0IVZz1l4HF72qrt-tXZZc

cloroxhomeappliances.com/products/clorox-ultra-air-purifier-with-uv-c-light-11060/?srsltid=AfmBOor3PS6pKaohdbu47DirSJs0fKYBUK2K3RYXtfZEwPt5Lq36WiFp

I want to take a "layered" approach, so I was thinking a hepa filter and a UV approach would be good. So I was thinking the Clorox option might be good, it's a HEPA filter with a light. But I'm just trying to gather and understand all my choices.

Any input or suggestions from people who are smarter about this than me?

Here's a calculator for your space to choose a suitable option: healthybuildings.hsph.harvard.edu/tools/air-cleaner-calculator/

This is another good choice because it's designed for a "whole house" solution but is less than 2ft square. That means you can "purge" when needed by setting it on high for a minute and then turn it down to a lower setting for you being alone. air-fanta.com/products/airfanta-3pro

There's not a good consumer-grade uv system yet, and the bulbs that are built into many air filters have issues like burning out and being un-replacable. (I had two before the pandemic that burned out so bad they shorted out the entire electrical system, and studies show they don't do more than a HEPA, especially in that format.) You're probably better off using a humidifier to keep humidity high (but not "mold-growing" high) in your space to assure aerosols drop out of suspension more quickly.

Thank you so much!! And that's a great point about the humidifier! I was already contemplating a small one bc of winter dryness, this is a great additional reason to do it.
