I really love my Shark Air Purifier 3 in 1 Max with True HEPA. It works very fast and is super quiet. I like that it works for up to 1000 sq ft. The fan works great at cooling my space, and the purified heat feels wonderful. The detachable remote is very handy too. I feel so safe using it with the advanced safety features. It won't tip over, and it doesn't get overheated. I suffer from allergies and I am a pet owner. I can tell such a difference since I started using it. The HEPA filtration is working so great. The air in my home is so fresh and clean now and greatly improved. I highly recommend this product and this is a brand I trust!
