I’m positively optimistic yet, we’ve only had them going for 3 weeks. Bedroom does not seem big enough for second bedroom with lots pet allergies. Moved large unit to the hallway. Definitely collecting dust and gray fluff. Very quick to open and vacuum filter off. Will keep going see how it’s doing in another month. Reason for purchase: for several indoor and outdoor door allergies, have 2 small dogs. Also to remove that dog smell. Yes, I bathe my wieners. 🐾

I bought the Sans hoping it would help with my allergies and dust in my house. It has really helped with sleeping at night. I don’t wake up all stopped up at night. I have moved Sans back into living room and have noticed I wake up stopped up again.

To be honest filter was not as dirty as I thought it would be but it was dirty. Need to move it to a more less compact area to let it get more air flow. Wherever I have my sans the air is fresh and clean. When my brothers dog visits you don’t smell do. Love my Sans. I need to buy a smaller one for my bedroom.

Love the sand color. Have noticed a bit of a reduction in dust . Would like more info online. Maybe a video of filter cleaning in between 3 months. Also wondering about moderate VOCs and what can produce them. Notice elevated reading near heat duct and maybe with cooking smells.

I literally can’t believe how great this air purifier works. I was on the fence for a few months trying to decide if it was worth the money and so happy I purchased it. It seems to filter out all airborne irritants. I have it set on auto all the time. Cooking odors never lingers. So happy with it!
