      The best humidifier I have owned so far

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I got sick very easy during winter because of the dryness. So, I normally have 2 - 3 different kinds of humidifiers in my house. I also need to replace older humidifiers or buy expensive new filters every year. I owned a few air-o-swiss as well as Pure Guardian. Previous I owned one pure guardian which has a too bright light. The air-o-swiss puff out the steam too low so I have to put a towel under it so the steam does not wet my floor. This Pure Guardian - Elite solved my three major issues. 1. You can turn off the bright blue light. 2. There is a pipe you can use for steam to come out high and does not wet the floor. 3. No need to buy new filters It is dry here so I think each tank can last between 8 to 12 hours. It is easy to refill too. you just need to take the tank out and refill the water. This review is for the product usage less than 2 month. I am considering buying another one with a bigger tank. By the way, it looks high tech too.

      Best buy!

      • Verified PurchaserVerified Purchase

      Owning many humidifiers, I am always looking for something different. I live in an open floor condo so balancing humidity isn't easy. Bedrooms are easy but large spaces are a challenge. This one is a gem! I was somewhat skeptical of the the removable hoses but that turned out to be the absolute best feature (well, there are others). This allows the humidity a circular flow allowing for better balanced even humidity covering a greater area. That is worth it alone! I don't use the timer but is a great feature. There is a light that is rather bright when you set timer, but if you are using at night just turn it away from you. There are so many great things about this product that far out weigh the light feature. Will buy others. Also silver tech so no worry regarding mold.

      Quiet and Dependable (so far)

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      It's light weight and has very response electronic touch pad controls. The level of humidity output is clearly visible and changes almost immediately as the control is adjusted. I've been setting the humidity control to 40%, low output, and at night I set the timer for 6 hours and it does exactly what I expect it to do. I use the two pipe extension for the humidity output which helps get the humidity up off the floor and into the room. A design improvement would be to allow the reservoir to be filled from the top. (although the bottom fill design may be intentional to make sure the electronics & reservoir are separated during the fill process)

      Excellent customer service

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      Got this one under $100, love it. No complain about white powder, I'm using filter water. The another option that pull me in is warm mist, this is great for Winter. One problem was water tank lid broken after 3 weeks of using, I summited email to customer service on Sat's night and got reply on Monday's afternoon to send out replaced lid. I took a picture of broken lid, no need to send back to company as same refer to company's website. I received less than 4 days. Works again.

      Great one room humidifier

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I bought this humidifier for my sons room in the winter months. This is a great humidifier. I like that you can adjust to either cold or hot mist and also has 3 levels of output. It is small but works quickly. This is the best humidifier we have owned to date and have had no issues in the 3 months since we purchased it. The only thing that I don't like is that I have to fill everyday, that is not the fault of the product just the size that I chose. Highly Recommend for single room use.

      Probably the Best Humidifier in Bestbuy Inventory

      • My Best Buy® Elite MemberElite Member

      Great design and elegant to look at specially at night. The extension is a plus but optional. The 90 hour is a misnomer because most of the time you want to achieve the full mist immediately so about 12 hrs or so but not 90 hrs. The refilling is underneath and it's quite a hassle when they can easily design it on top. Black is okay but I would advice you to get the white instead because black color gets frosty on all sides and really bad to look at during the day. My wife is now sleeping pretty well after a month long of severe cough.

      not great

      • Verified PurchaserVerified Purchase

      The screen light is so bright we have to turn it backwards at night time. We use the extension attachment to help spread the humidity and that works well. I don't feel any difference in output temp between warm mist or cool mist and I bought it for warm mist, so I'm not pleased with its performance. If you have the setting on high and humidity is low it will run out of water in less than 24 hours and you will need to refill.

      Not bad.

      • My Best Buy® Elite Plus MemberElite Plus Member

      Decided to upgrade our regular humidifier to something fancy. So far this isn't bad. Like the features especially the extension tube for the mist. Nice seeing the mist coming out. Build quality is OK. I think our previous one was a bionaire which was a sturdier build. An important feature to me is ease with removing, filling and placing the water container. My previous one was rock solid, well placed handles, no spilling. This one does a good job, but not great. Still, so far, I would recommend.
