Purivortex Air Purifiers for Home Large Room, CADR 300m³/h with Air Quality Monitoring and Washable Pre-filter, Efficient 99.97% Dust, Smoke, Pet Dander, Odors and Pollen, Ozone Free

Dusty cockatiel has met his match!! I am finally able to dust a table and it stays clean! When my dusty feathered friend flies past the purifier, the lights change color and the numbers go up, so this is definitely sensitive. Stinky smells coming from outside, like cigarette smoke and truck exhaust get sucked up quick. The air in the house feels cleaner and smells fresh. I am going to purchase a second unit for my bedroom so I don't have to turn off the one in the main living area.

We have one in the bedroom and one on our sitting area. Results showed up on the filter. I was hoping there was a ionizer in it. But it is doing the job with 2 cats and 2 dogs and a wood stove.

Buy this if you’re looking for a cheaper alternative!!I have had it for about a month. I got this for my studio apartment and am very happy with it. The noise level at 3 is on the louder side but this level is only used when I’m in the Auto function. Auto has a sensor that detects when there are more particles in the air (from cooking or something else). The auto function works so well! I blew out a candle in another room and in about 15 seconds, the filter speed increased as it tried to filter the smoke. I have no negative complaints about this filter.Overall, very satisfied with this product and would buy this again.

Ok bought this end of sept.Sept.. worked fine at first, 2 weeks ago it started staying on red, 500. Meaning the filter is too dirty... I'm extremely disappointed in this product.. I wash the pre-filter every day... there's nothing in my house to make it THAT DIRTY THAT FAST!! Useless peace of trash. I'm not buying a new filter already!

We love it! The house smells great and the air feels fresher. We have it in our downstairs space with three rooms (cat litter boxes) we have 3 cats and a dog. Our closest friends have noticed a difference when they’ve come over! Washable cover is awesome!

I think the device did an OK job absorbing the smell after stir fry. The highest fan mode can be pretty loud and the lighted buttons may disturb your sleep when leaving on.

Works well to filter dust and particulates. We just keep it on auto fan speed and the noise level is low. Notice a lot less dust as we placed it right by the furnace and air intake. Filters for the unit are fairly inexpensive.

Update: I moved into a new place on April 1st. I had suspected the air quality in my old place was wrecking havoc on our health (which it was). But, without changing the filter, the air purifier worked just fine in the new place. However, again after a month of use, it is stuck on red. All in all I’ve only used it a total of 2 months since February. I will say when it works, the air feels clean.Original: This worked great at first, noise level is good. No longer works. This thing is now constantly on red and I’ve only used it for a month.
