Best Buy Customer Reviews

Purchased for use in car2 Posted by: from: Moon Township, PA on This machine is a great little air cleaner for small spaces but I had difficulty getting it to work properly in the car and I have a Pontiac Vibe that has a regular electric plug right in the dash - problem being that the plug didn't exactly fit properly into the electric socket because of the shape of the dashboard. . .

It Did Nothing2 Posted by: from: on Just as my summary was. It has a nightlight and a soothing sound that's it.

Awesome for small spaces!5 Posted by: from: Papillion NE on I bought this for my son how's a smoker and his car always smelled like smoke. We took and cleaned out his car (wiped it down on the inside and vacuumed real good) and plugged in the air purifier. By the time we got home we both could tell a difference and within a few days couldn't smell the smoke at all.

Smooth Operator4 Posted by: from: on I stayed at a hotel in downtown Houston and found musky smell really bothered me. I decided to buy a portable air purifier. I found this product extremely useful. It's not just small, but it has no consumable parts. The ionic technology filters out mold and odor. Just wipe the blades with toilet paper. I am allergic to air fresheners and I need my hotel room to be odor free before I could stay. So, it has been traveling with me ever since.

Works like it's supposed to.5 Posted by: from: on Very happy with product. It's quiet. It cleans the air. Filter blades are easy to clean. No problems or issues. The price was reasonable too.

small air purifier2 Posted by: from: on I actually returned this small air purifier because i had no place to plug it into a wall socket. I had planned on using an extension cord since it has no cord with it but, after opening the package and reading the info packet inside, it cautioned against using a cord. I wish this info had been on the package exterior and saved me the effort. Also, how many of us have empty wall sockets?
