Rovacs focuses on smart home products, air purifiers, sweeping robots and other smart home appliances. It is a brand that integrates industry and trade.

 I bought this air purifier because I had guests over at my house and they were not impressed with the smell from using medical cannabis. I had no idea that the smell lingered in my house long after I was done smoking.
This air purifier has huge filters on both sides of the unit. The filters sound like they are full of beads.
If I turn the fan on to the highest setting. I can blow smoke into the intake and all the smoke disappears. This air filter gives my house fresh clean air, and I love it.

After using this air purifier for 2 weeks now I have noticed less phlegm/mucus in my throat while sleeping. In the past phlegm in my throat has forced me to wake up in the middle of the night and have issues getting back to sleep.
I noticed I have been sleeping through the night without issue since using my air purifier. I can not imagine going back to restless nights.

With all that said, I feel this air purifier has earned a 5-star rating. First, because it does a great job at cleaning the air, Second because it was less money than other brand purifiers, and Third it runs quietly. All around has been a great air purifier.

 I recently bought the smaller version of this air purifier and was impressed. I have an air quality monitor in my house and tested the air before and after a day of using this air purifier. I wasn't sure what I would see because this air purifier barely makes a sound. I like that the temperature and humidity are clearly displayed on the front of the air purifier. What convinced me to buy this one was the fact that it advertised that it would re-circulate fresh air six times per hour in a 750 square-foot area. While the main living space in my home is slightly bigger than that I figured it would hold up especially as it says it can cover a 3500 ft area.. It has definitely helped and I feel that the air is cleaner overall. Working in healthcare I often feel that I am carrying a lot of things home with me and this helps give me peace of mind to know that even if it enters my home it won't be here for a long period. Its also really helped with the pet dander at home. My fiance is allergic to our cat and he hasn't had to take an allergy pill since we turned this on.

This air purifier is quiet at low fan speeds and acceptable at higher settings. At the highest fan speed it is equivalent to someone blowing air with their mouth.

I like that there are two large filters and the capacity of this model. We have a large classroom (2,000 sq ft) and this purifier helps to cycle the air. The controls are very simple and we place it on automatic so it adjusts the speeds based on the sensor readings of pollutants.

The machine is lightweight and can be moved as needed. The only thing I could not figure out is where to get replacement filters when the time comes.

Other than that, there is just the power button that is pressed to cycle through the available modes. The “green ring” indicator changes colors to yellow and red as the filter system determines if changing is required.

I first saw this unit at my doctor's office, and later that week, I saw it at my physical therapist's office. Honestly, I did a lot of research before purchasing this unit. What convinced me were the great features including the ability to filter to .1 micron, the HEPA filtering, size, and area covered. So I decided to get myself one for my home. With this unit air running, it's noticeably fresher air in my house. My allergies are much better while the air purifier is running. It is very quiet; you can't hear it, which why I love the timer; otherwise, I would forget it's running.

Overall, this is great, I had severe allergies, and once I turned it on the next day air in my house was clean. I felt better no sneezing or watery eyes. I love it I would highly recommend it.
