    Literally had the worst allergies "dry cough" 3 weeks. Covid (-) x3. And this came in and 5 days later im normal. Live the settings, quiet, you can turn off lights for night time. Now i was on steroids and meds. But i think everyone needs a purifier.

    So great! It barely takes up any space because it's narrow. I love the different information it displays and it looks cool while purifying the air with an automatic setting.

    This machine is awesome . Is has an auto select and when the air gets odors it will automatically speed the fan up to get the odors out. It is extremely quite. I thought it went off after I first turned it on and the fan was on high working on the rooms

    So far does OK. Pretty much stays on blue until I cook something really smoky in the house and you can hear the fan kick up a notch and the meter changes color to let you know it is cleaning the air. I just hope I can find the replacement filter when the time comes. I purchased the unit although there were many reviews stating they could not find the filter. I even looked and it was out online.

    This product is great! Not sure how accurate the smart sensor is considering the room was filled with allergens and it said 100% clean air yet we were having a difficult time breathing, but by the next day after cleaning and this machine, we were able to comfortably breathe again! This is our second of the same machine. One in the living room the other in the bedroom. Makes breathing once again easier.

    It does clean the air and I hardly know it's in the same room because it is so quiet. I've been wanting some kind of air filter for my home, and I am very glad I made this purchase.

    I love this thing! It was worth every penny I spent. I have pretty bad allergies & it works to keep my allergies at bay. The only downside is how expensive the filters are.

    Great purifier. I’m a person who has dust allergies and this device has allowed me to calmly sleep at night. Also device fans are super quiet. Highly recommend it for someone who has trouble with their allergies.

    Love this unit for size and functionality. Unfortunately it was a little too small for the room I bought it for. Returned it for the larger six unit. Highly recommend for a smaller size room such as a large master bedroom

    Works great. Covers the entire house with no issues. The level of allergens have greatly dropped since using this and my asthma and allergies have slowed way down as a result. Would recommend this to anyone.

    So far, so GREAT! I have not had the filter for long, yet have noticed I am waking up with clearer sinuses, breathing and eyes! I have to believe it is helping with the naturally occurring allergens in my home.

    The reviews were good so we tried it. It does everything the description says. Great job of ridding the air of odors as well as cleaning the air. Absolutely would tell a family member to buy it.
