I wished I would have tried one of these earlier. I get really bad allergies and that brings on asthma. Especially when I go to sleep. This machine has clear that up pretty much 100%. I am amazed.

We love it. There is a noticeable difference in a room after a couple hours - especially with stale air in a bedroom or cooking odors. We love how it senses the odors and kicks on automatically.

Such a great concept. A really nice looking unit. I wanted to love it; I was prepared to like it. This was purchased for use in my kitchen due to heavy dust. I have no idea why dust has become such an issue. All appliances are black and I can use them for message boards. This air cleaner has become one more object to dust.

I bought this air Purifier almost a month ago under the assumption that it would cover a 1200 sq ft area. According to the owners manual the applicable area is 861 sq ft. Why is Sam's club advertising 1200 sq ft? I have 4 german shepards and 7 puppies in a room that's approximately 400 sq ft with an open archway to another room that's about 600 sq ft. placing the purifier in the middle of the opening. According to the air filter it is doing its job. I leave my purifier running 24/7 so the remote is of no use to me. It does just as good a job as the filtrete brand that has an applicable coverage area of 310 sq ft. Doesn't seem to do much better. The filters are more expensive than the filtrete brand. The plus side is that an additional filter was included with the purchase. I have an Idylis brand which is a much better air cleaner than both of them but again the filters are expensive. The three brands that I have does work. I have no air testing equipment or any sort of controlled method of professionally testing so the filter is all I can report on how effective they are in that location for that time under various conditions. Placed in the same location and ran 24/7 for 3 weeks the Idylis brand which I have had for over 9 years picked up the most. The filtrete brand picked up the least. Noise level was good on the Air Shield. TV goes louder. They are all made of plastic which seem cheaply made. But nowadays that is the norm for all manufacturers. Make them as cheap as possible for disposable purposes. Throw away and have you buy a new one.

I have COPD plus we have 5....yes 5 cats! I have been quite miserable. Upon hooking this unit up I have been awesome. Not enough words to express my gratitude with the Advance Air. The company even called to follow up on the sale and offer their direct phone number if we had any questions. Top notch company.

I have numerous air filters because of my asthma and going away this is the best..I bought two and wish I had 2 more and the service..I called with a question and a real person named Alison actually answered and was so knowledgeable that she blew me away..any negative reviews must have been place with people that own stock in other companies because you cannot beat this purifier

I just got two kittens, put them in my home office to be able to isolate the smell. I also bought quality cat litter, but the smell was still there even though I cleaned the box 4- 5 x a day. So I bought this advanced Pure Air Shield Purifier. Fantastic buy, no more stitch - now we can even keep the door open. I run it during the day and turn it off for safety at night. We will be building a cat litter bench to hide the trays.

Not sure if it's really working on cleaning the air in my loft

It's like a fan that never works. You can throw a budget of dirt at this and it won't do a thing

Works great. Very quiet on lower speeds
