Question: Can anyone tell me what the CADR is on this unit? They claim good for 3500 sq ft home, but at what rate? That does not sound right, efficient for 3500
Document: it works great for my 1200 sq ft home. I have it in the basement and you can even see the difference upstairs. it does just as it says it will. It pulls the dust out of the air and cases it to fall on the ground. I have a wood/coal stove which can be very messy. the day I put it in there was dust/ash floating everywhere, within the first half an hour there was very little dust floating in the air even with a fan on.
This is the best air machine for the money I have ever purchased. I have one that cost twice as much and doesnt do as good of job. The reviews suggest Blue Air,etc.which cost a lot more. I  havent seen any reviews on this one but can tell you it is worth every penney.
We originally looked at the cloud unit (without the ozone feature) because we have a son with asthma, but upon further research we found out that the ozone feature isn't constant and can be turned on or off at will. We figured that it is a nice feature to have if we want to set the timer and freshen the air while no one is home and have it cut off some time before we return.Overall the only complaint (and a VERY minor one!)
I 'medically' needed a good air purifier to clean the air in my home. I researched for almost an entire week and it seemed that this Rocky Mountain Air purifier would be the answer. It arrived and my husband and I looked at the instruction booklet and we were shocked to know we could not read the instructions on how to put this together. Just too many parts to put together and this was not mentioned prior to ordering. I guess if you are a brain surgeon this may be your baby.
Has really cut down dust in the office and the air is much cleaner - I would recommend this to anyone with allergy issues or if you just want cleaner air
The construction is high quality and hopefully will last a one time. I am a firm believer in reading reviews  before buying anything these days, but true reviews should also come about a year after the purchase and not a month, otherwise a true test cannot be observed. So far- so good. I am happy and am pleased with the item. For the price the purifier seems to be very high quality and very effective.
This purifier has met and exceeded my expectations! I have a son who has a tracheotomy and has had his left lung removed. Because of his respiratory needs this unit has met and exceeded our needs for his over all health. Not only his health has been improved but we have found the rest of our family has been enhanced health wise as well. I would recommend this product to everyone who has health needs or those who just want to have a better way to breathe.
I was aware of commercial cleaning companies using Ozone to clear the smell from smoke damage, but did not know what to expect from a small unit such as this one. I have to say that it is quite an amazing piece of equipment. We live in a 110+ year old house which means that there is plenty of dust to keep makers of Pledge happy. Dusting at least once a week was not an option, but mandatory.
After just a few days, it was amazing to see how much dust was being removed. It has made the air fresh and clean, much appreciated especially since we are allergy sensitive. Well  worth the investment. Have done the first cleaning of the filters without any problem or difficulty. We use this in our home only and are very happy with it.
i have emphysema and this unit seems to help me breath easier. But - I must say what Consumer Reports says about air purifiers: you can add to the effectiveness of any air purifier if you run ceiling vent fans (typically they're located in the bathrooms and kitchens ) and use your vacuum cleaner regularly.&#34;7-Stage&#34; air purifier? I'm not sure about that but the electrostatic plate (air purifier) does work on tobacco smoke and other fine particles.
Answer: I don't know about 3500 feet but my basement is 2000+ sq feet and I have to use it on low otherwise I get that metal smell. It's Definately powerful .
