It is pretty difficult to filter out ultra fine particles anyway and some of the best air purifiers can claim to do a lot. Obviously, you will be breathing that stuff every day and unless the air around you is seriously affecting your health, you don't need a high end air purifier. This is my opinion, but unless you have allergies or asthma, most top of the line air filtration systems won't have much of an impact on your day to day and I would personally suggest any $250-$500 range air purifier. This content in this article[1] does a really good job at comparing air purifiers but they suggest an ionizer which can have negative effects. Things to look out for: - No ionizer. - No uv light. - True HEPA is fine but if they've trademarked or registered their HEPA brand (HyperHEPA, HEPASilent), I would ask them more about what that means and they should provide a pretty good answer within the context. 1. http://thesweethome.com/reviews/best-air-purifier/ http://thesweethome.com/reviews/best-air-purifier/
