Small, compact extremely efficient air purifier wi
on November 21, 2025
Posted by: E3 North Port
I bought two of these air purifiers. The two big takeaways are:
1) They are highly efficient and very quiet! They only turn on automatically when the air analyzer identifies that particulates in the air need to be removed. This saves primary energy use and keeps the air fresh.
2) They have integrated scent production using remarkably well-priced scent pods. Makes the rooms smell really nice but not with overpowering scents. A definite benefit.

The purifiers put Hunter purifiers to shame.

Need a filter.

It isn’t working. Looking for a filter. Bought this one about a year ago and can’t figure out where to purchase a filter. We had a Dyson and it doesn’t work at all
No, I would not recommend this to a friend.

Unfortunately not a very good filter.

Really doesn't work well with cigar smoke. The filter gets dirty very quickly so you have to constantly vacuum it to get rid of the particles. Not worth the price
No, I would not recommend this to a friend.

Best hepa air machine on the market

Gender:Female
Ours lasted about 2 years before it just stopped one day abd the screen showed to dash marks I assumed it meant the main filter had finally given out. Now we ran this thing hard daily 24/7 so a little over 2 years is acceptable in my opinion plus we have multiple long hair dogs, long hair cat, etc. This thing is an absolute work horse! Only reason not 5 stars is cannot find official replacement filter anywhere so cannot use without it!
I would recommend this to a friend!

Great in theory, poor in performance

Purchased this three weeks ago, have had it set up for a week now running, the prefilter screens on both sides are as clean as the day I turned it on the first time. My window AC unit filters more dust than this thing does. I would return it but I threw the box away, stupidly, because every Shark Vacuum I own has been amazing so I thought this should be as well. WRONG. My little dog is litter trained, when he goes to the bathroom the unit doesn't even kick on from auto to a higher speed to clean the air, 30 minutes later the air smells the same. I am going to give it a full month then if it doesn't work I will bite the bullett and buy another brand.

Instructions Could Be Better
on August 26, 2025
Posted by: Hoping4CleanerAir
Just bought this as a recommendation from a friend. Set-up instructions were easy; however, it only came with 1 page and nothing about the control panel settings. It took me a long time to find my model (the website is huge) and finally found the manual. But, the font is so tiny on the control panel I had to get magnifying glass to read. Shark can do better. You should send complete instructions with this product. Some folks do not have internet and capability to read tiny font. Please improve. Hoping this unit does what it's supposed to don.
