Hello All,
I have decided to put an air filtering system in my garage. My garage is 20x18x9= 3,240 sq ft. I am looking at the WEN because of pricing. My question is, they have two models. The cheaper model for $150 has a CFM 300/350/400. The model for $250 has a CFM 556/702/1044. According to the calculation, the smaller model would be enough for my garage. But would it be better to buy the bigger one to clean the air faster? I don't know if this is relevant, or a waste of money? I normally work with my garage doors open as well. But there are times the weather is too cold for this. I appreciate the feedback!
Thanks,
Chuck
