Q: Would you say this unit is fairly quiet or noisy?
A: All of the Winix units are pretty quiet. Here are the unit decibels for the Winix P450 (low/medium/high/turbo): 27.0/38.0/50.0/60.0
Q: How often would I have to change the filter on this unit? Since its not a washable one...
A: I actually vacuum both the black and hepa filter every day to make sure that I enjoy peak performance. How long does this practice prolong the usage of the hepa filter? I don't know, but it is worth giving it a try.
A: No ozone. I had a machine that omitted ozone. It bit the dust so I got this unit. I love it. I have 2 dogs and you cannot smell dog in my house. My niece has 2 "big" dogs and my eyes used to water when I went into her house. I bought one for her and it has made a huge difference. I don't know if it will work on cat urine smells. I do not believe it will work like an ozone machine. My ozone machine if I ran it on high would take every oder out of the room in a 12 hour period. Hope this helps a little.
Q: how may times per hour is the air circulated in a 450 sq ft room?
A: Air Changes per hour for the Winix P450 are as follows (low/medium/high/turbo) 6/14/23/38
