Avoid this PLAGUE The Blueair company is a wonderful company to work with and helped settle my issues. I ordered 2 of the 501 units with replacement filters sight unseen based on user reviews. This is a very quality built unit, but the speed settings on the fan are far from usable. The lower speeds barely move enough air, yet the high speed is so noisy that you will think a tornado is in the room with you. The company gladly exchanged my 2 501 units with the 400 series units. The 401 units are far quieter and way more efficient in the way in which it moves the air, so order the 401, you can't go wrong. Keep in mind the 10 year warranty is only applicable if you can prove that you purchased and changed the filters every six months, if not no warranty exists, and the filters are not free, but affordable. In my opinion the 401 is the way to go, stay clear of the 501's due to the noise and air flow design, the Blueair company is second to none in customer support and are highly recommended. Thanks Blueair for helping me get it right....This is one heck of a company that will take care of it's customers. Also keep in mind when you order a Blueair purifier unit, one filter set will come included with the applicable unit that you order. If you order filters, they will be used later for replacements, I wasn't sure when I ordered if the filters were included but they were....more info
This is the most powerful HEPA on the market for the money. This item is extremely high quality with a medical-grade fan. It is also the only filter on the market with a 10-year warranty.
I live in NYC post-911 - and I've owned the 501 ever since then, regularly replacing my filters. I am asthmatic and am an avid cyclist. Air quality is important to me.
My friends with EVERY OTHER MAKE OF AIR FILTER say it is the best filter they have ever seen.
If it's too loud for your liking, that can be read that in the specs - and to be considered before purchasing. If you want air movement, you need a powerful means to do it. That is why this model has a best-in-class rating for air circulation.
This machine is well worth every penny. As we have all seen, Ionic Breeze is crap and it pays to go with a tried and true; allergen-expert-tested powerhouse....more info
Gary Hoyt I ordered this item was disatisfied with it, sent it back.
From the engineering and design to the noise it made left allot to be desired.
Purchased two G.E.'s that work efficiently and in my opinion are superior products at about 1/4 of the price....more info
