Levoit Air Purifier, PlasmaPro 300-P, Filtration for Large Rooms, 215 to 1043 sq ft, White

This is the first air purifier we bought. My daughter had a wet morning cough that wouldn't go away for months. The doctor said it was probably allergies, and since we live in a rural property it made sense. I'm glad to report that her cough completely went away after a week or so of using this purifier. I only use it at night in her room.

Works well with the size of my bedroom. Noticeable difference in air after leaving it on for an hour. It does make a bit of noise even on the first setting but that doesn't bother me too much since I like it as white noise. After that though the sound keeps me up but since it does a pretty good just even at the first level I don't even have to change the settings.

This purifier is tops in every way... compact, stylish, quiet, and, most important, very efficient. I love it so much i sent one to my sister!

This model works well in large rooms. It's quiet on low and medium settings. I use it daily for my allergic rhinitis and also when I cook. It really cleans the air and no greasy smell from cooking or pet odors. I recommend this product.

I am absolutely thrilled with the 3 air cleaners we purchased for our 2600 square foot home. Nearly immediately our house with 4 pets smelled better. We have now been using the Levoits for about 2 weeks….. and all have WAY less allergy symptoms and see less fur. The house smells fantastic when we come home. I couldn't be more pleased!!

I suffer from severe allergies 365 days a year. I placed my purifier in my bedroom and set it for 8 hrs when I go to sleep. I have been using it for about a month and have noticed a dramatic difference in my breathing in the morning. I don't wake up full of congestion or sneezing. I have noticed when I'm at my office my allergies tend to act up, so I will be ordering one for my office soon. I highly recommend this product for other allergy sufferers.

This air purifier has been a game changer for 2 of our rooms. It has resolved all the issues I have had with allergy symptoms and there was a musty odor when we moved into the house, that is completely gone. Definitely recommend this purifier for smaller rooms.

Like the 3 speeds, have it on High or Medium during the day, Low for night time. Super quiet. After 2 weeks, checked the filter and their was "little" dust. Would like to see what it looks like maybe after a month or so. So it is working, I suppose it's how clean your house already is. Would recommend.

Sleek, easy to use, and effective at keeping my workout room odor-free. I just wish the top fan setting was a quiet as the first two settings (nearly silent), though it's not at all loud.

Piece of junk. It turns on but there is no difference. Been using it for 3 months and there has been 0 difference. I do not recommend it! My allergies are still there, my sinus is as bad as ever… did not improve anything. Got a big one and problem solved!
