#1 Q:   For the Airscape 1.7 WHF-XR, I am wondering about the optional RG-1422 openable and washable grille.Is this a good upgrade over the grille that comes with the fan itself? Is the standard grill not openable, and not washable?
A:   The standard grille is washable as it is aluminum that is powder coated. The openable one just allows for easier access to the back and such. I use a brush attachment on my vacuum and it works great on the regular one.

#2 Q:   Total home sq footage is 3,500 s.f. The main living level of home is approximately 2300 s.f., and the area that we want cooler. Downstairs approximately 1,200 s.f. (3 Bdrms) always stays 10+ degrees cooler, and I dont believe needs additional cooling. Would the 1.7 WHF, be adequate for my cooling needs, or too undersized?
A:   It would be undersized a fair bit on that home...2.5e or 2.8 Kohilo would provide much better results.

#3 Q:   How big a house can I cool with the 1.7?
A:   Depending on the area of the country, this fan should adequately serve a home of 2000-2200 square feet.
