Calming and relaxing

A very economical way to ensure you're home is fresh and clean. I have breathing issues as such I'm not a fan of home fragrances, this keeps the air clean and fragrance free at all times. The last unit lasted close to a year. When you have multiple it spreads out this work. Circulation of the air is whisper quiet. The only time it automatically speeds up is when someone opens the doors. Other than that you literally forget it's working.

The machine is so simple to use.. You basically just unpack, insert the filter, plug it in and it automatically goes to work. This product is very quiet and has cut back on my dusting.. The air even looks crisper.. I only wish that it released a nice room scent freshener...The only downfall is that it continues to shut off and doesn't help much with the odors of smoke...🤨 Needs some Improvement.....

Nice purifier

I like this air purifier. It's very quiet - I finally had to change out the filter and it was very easy to install new one...another reason to like it.
