I really like the Shark HP202 Air Purifier MAX. First off, the air purifier is fairly large, and very stylish looking. Included is an easy quick start guide to get you started, and the product is very easy to use. A great feature is how the air purifier cleans up to 1200 square feet, which is perfect for my home. You can really see it working after you've cooked a meal. I like how the indicator light is large, and can be easily read from a distance. The product also removes dust, pollen, smoke, and other items from the air. The product is fairly quiet, but some times makes a little noise when cleaning the air. Another nice feature is how the product comes with an HEPA filter, and the product helps to rid the air of bacteria and viruses.
