This Shark air purifier is pretty awesome. It purifies quickly. I just finished a large room in our downstairs and it is about 500 square foot so, this is perfect for that space. It is a great size also. Not too big or too small. I have two cats and this is great for dander. I like that it can clean 99.98% of dust, allergens, and viruses. The look of this purifier is beautiful. It is white with blue lights. We love this purifier as it is very high quality. I'm sure you will love it too.
