We're not talking about big bucks, but when you're trying to find the best value for money, sometimes a product's performance is worth it. I forgot my artist threw away my filter and when I use it you're usually looking at what's in front of you, not what you're leaving behind. When I finally turned around and saw the dust column, I remembered that there was no filter there. After seeing several options, I settled on the one that treats fine dust. It was literally 1 step install and it works. MARVELOUS!
