I got this Shark Purifier for my livingroom. Coming out of Covid, I feel like I needed to keep the air in my house healthier. This purifier does just that. I can set it on a mode to purify the house until the system test that the air is clean. I think it does a great job since I can feel the air smell fresher than before. This purifier is very quiet. I have it running all day and can barely hear anything even when it is active moving air around. It is also very sleek looking and actually look great in my living room. There is a heat function as well but I have tried that yet to see what it would actually do. The filter is very easy to remove, clean and replace.
