Query: Quiet & Effective Air Cleaner

I already had the larger Winix 9000 that works great for the open floor planned downstairs. So figured the smaller 9000s would be great for my newborn daughters room. It works great in eliminating smells such as poopey smells and other odors. And it is quiet, which was an absolute must since it is in the nursery. I don't know if the allergens have been reduced downstairs or in her room since I still have allergy symptoms when I am home...Anyway I wish I bought the 9000 on Amazon to save some money, but thankfully I bought the 9000s on Amazon, much cheaper than on the winix website. I plan on buying another 9000s for our bedroom in the near future.
