Product Overview

The Vornado AC300 Whole Room Air Purifier uses true HEPA filtration, the most effective filtration available, to remove up to 99.97% of airborne allergens down to 0.3 micron. The Vornado Whole Room Air Purifier actively circulates and filters all the air throughout a room. Without circulation, the air cleaner is only cleaning the immediate area around the unit, relying on general motion to push air through the unit. The AC300 uses a combination HEPA/carbon filter to trap Dust, Pollen, Pet Dander, Smoke, Bacteria, Mold Spores, Dust Mites and more. The carbon pre-filter both absorbs odors and traps larger particles. Features 3 speeds, push button electronic controls, filter replacement indicator and industry leading 5 year limited warranty.

No, the unit only filters particles from the air. It will not kill mites and spiders.

Rated 3.6 out of 5 by 29 reviewers.
Rated 1.0 out of 5.0 by Horrible product and customer service. Warranty is worthless. Just like the AC500, this air purifier worked well at first but let me down rather quickly. I used it in smaller rooms of the house. It was loud but not too bad, and it wasn't as loud as the AC500. After a month or two the purifier began making a loud rattling noise every time I used it. A few days later it would not even circulate any air around but instead began making a humming noise. This same exact thing happened to the AC500. It hadn't been damaged and the filter didn't need replacing, but I was confident I could get it replaced or fixed because of Vornado's warranty. I contacted Vornado multiple times about both models within months of my opening and using them. They fell well within Vornado's so-called warranty... Customer service didn't even bother responding! Consequently I do not recommend this product or anything else from Vornado. June 13, 2016
Rated 5.0 out of 5.0 by Everyone Should Have One of These! I have severe allergies and I recently quit smoking so this product is a godsend. The unit is not as loud as my fan when it is on high. On the low setting you can barely hear it. The unit was simple to set up and use plus it is sleek and discreet in appearance. It also lets you know when the filter needs to be replaced. This True Hepa Air Purifier is wonderful! It definitely refines the air in a larger, high traffic area. I used it in my living room. I was aware of these products before but never tried one. Now I wonder how I lived without it. The air quality in my home has improved tremendously. August 18, 2015
Rated 4.0 out of 5.0 by Not what I expected but I really like it. I have tried air purifiers before and was really disappointed. The units I've had were really expensive, expensive to maintain and were very noisy. When I was invited to try a True Hepa air purifier I thought it was going to be the same results, disappointed. Well, I was wrong. I've had the unit for a little over a week now and I really like it. The design is very nice and it being tucked away in a corner, you don't really see it. The noise element is not very bad at all. On high, it is a little noisy but it's on high. The other lower settings are quiet and I've had to look at the unit to make sure it was still on. So far, I'm very impressed with the unit and look forward to continuing to use it. August 17, 2015
Rated 5.0 out of 5.0 by I would definitely buy this product I was very pleased with the unit. It was quiet and took the smoke out of the room from the surrounding forest fires very quickly. I would definitely recommend this product. November 9, 2015
Rated 5.0 out of 5.0 by Awesome Product The True HEPA Air Purifier is in our living room and it has really made breathing much easier in our home. My husband who has allergies says he notices a difference. It has cut down on dust in my living room. I dusted two weeks ago. I have not had to dust again. I would normally need to dust by the next day. I haven't had to change any filters on it yet but everything is working fine. I love how I can change speeds on it. It could be a little quieter on the high speed, but you do have the option to lower the speed. I highly recommend this product. August 24, 2015
Rated 4.0 out of 5.0 by Happy that I could try this. We use this air purifier in the livingroom, which is open to the kitchen and diningroom. I had never heard of this brand and i did not expect it this big. We were used to little boxes you set on your table. It was very easy to set up and figure out how it works. It's a little noisy on the highest setting, but we usually just have it on low and you can barely hear it. We only run it during the day and turn it off at night. Since we first starting using it about a week ago I haven't been sneezing as much, so I do belief it works for allergies. The air also feels fresher and cooking odors don't stay around as long. This was a free sample for us to try, otherwise it may have been a little to pricey for us. The replacement filters are affordable and should last us about a year. I would recommend this air purifier. August 18, 2015
Rated 5.0 out of 5.0 by Works great and cleans the room like never before. I used in my bedroom and it didn't take long to see that this unit would make a big difference in the air quality. I love the design, nice and sleek, easy to operate and doesn't take up a lot of room. Easy to use and move around when needed. The unit is a little noisy for me, so maybe I will move to the hallway.

Rated 5.0 out of 5.0 by Thank you! My 7 year old has really bad allergies and we live in an old house which is always full of dust and dirt no matter how hard I try to keep it clean. I've tried other air purifiers but they just don't seem to last very long and are soooo expensive to maintain they were no longer cost effective. I like this True Hepa Air Purifier because so far it has done what the others have not, purified the air in my child's bedroom. After receiving the unit I put in there and turned it on high. It was a little noisy but not annoyingly so. After I let it run for an hour, I went into the room and it was like going outside after a rain. It was fresh and it smelled good, if a child's bedroom can smell good. That first night I turned it down to medium and it was very quiet. My child had no problems sleeping with it on and the next morning the complaints of stuffiness was gone. I've also noticed the dust accumulation is significantly less as well. Overall, I am quite happy with this unit and would recommend it to anyone. August 17, 2015
