I’ve always loves shark products and this Shark Air Purifier 3-in-1 MAX did not disappoint! I have an older house and have issues with allergies. Since I’ve been having this air purifier, my allergies have gotten better. I’ve also noticed that I don’t have as much dust build up on my furniture. 
The set up was very easy and it’s just as easy to operate. There is a fan setting and a heat setting that both work well. There is a replaceable filter that is easy to change also. I’ll be purchasing one for my bedroom soon!
