Best air purifier for 1,000sf apt in Boston, MA -- primarily concerned about busy 4-lane street outside, particulate matter
I just moved to a new apartment building on the third floor with windows all facing a busy 4-lane street. I am the type that usually loves to keep my windows open, and am concerned about doing so next to such busy street with all the particulate matter being kicked up. It is just me and my partner living here, both relatively healthy adults, but I want to make sure my body lasts me a long time!
I am researching what air purifier would be best for this situation? The apartment is small, about 800 sf across two main rooms separated by a door, with ~8' ceilings. The bedroom is carpeted.
So far, I have looked into Coway, Winix and Blueair. The blueair medium spi3 is the strongest candidate that I've looked at, but of course there's been lots of conflicting opinions and information on what's best. Please let me know if you have tips or recommendations for this situation!
Additionally, noise levels aren't a huge concern -- the busy street is noisy so I welcome some white noise to cancel it out. Budget is flexible, willing to splurge a bit for quality filtration, ideally <$500 with <$50 per year for filters, etc.
