Good

It's a great unit, especially considering its size. Great for a bedroom or similar sized room

Update as of 1/8/2020 -I bought this purifying system because husband was having breathing issues due to mold in the house. After the issue was fixed we needed a powerful machine to do the job (we have a bigger house). When I tell you this purifier changed the quality of the air in the house, it’s an understatement. We love it and think it’s amazing.The best thing is that we can move it to any room in the house that needs an extra cleanse.I totally recommend it. It has been over a year and it’s still working great.

Bought two of these to help control dust in my dental office as we replaced flooring and had to grind the cement floor.

This works great. We do interior remodeling and its wonderful for dust control. Great for demo including concrete cutting and drywall work. I would highly recommend this. I love the washable filter on the outside. That saves us a ton.
