Levoit PlasmaPro® 400S-P Smart Air Purifier

[This review was collected as part of a promotion.] I have been using the Levoit PlasmaPro™ 400S Smart True HEPA Air Purifier for over a month. I have a 4 bedroom home and I have put the air purifier in the center of my home. I can tell a difference since I have started using it. I highly recommend this product.

[This review was collected as part of a promotion.] This is a great air filter for a bedroom. My son has some allergies to dust and pet dander. This really has improved the quality of air in his bedroom. It is very quiet and he doesn’t even notice that it’s on!

[This review was collected as part of a promotion.] My daughter suffers from allergies and asthma, and using this air purifier has been a game changer for us! I was skeptical at first, but soon noticed that it was really helping her, especially with some of the poor air quality we’ve had this summer. I can’t believe how much it actually improved our air quality. Set up was a piece of cake too. It makes a little bit of noise, but after an hour or so, I didn’t even notice it. If you, or anyone in your family suffer from allergies or asthma, this is definitively worth trying out. I was so surprised by how well this performs. It definitely did its job!

Mostly great. It keeps disconnecting from my business internet. It also is not removing odors.

[This review was collected as part of a promotion.] I have been looking at getting an air purifier for a while now, but I was very hesitant on which one to get. I bought a different brand smaller unit and I did not notice much of a difference. Once I got this one..... ABSOLUTELY made a huge difference! I love how it has a 360-degree air inlet with a top air outlet. The digital screen on the unit is very clear and easy to read as well. I can see the current air quality in my house on the digital screen as well as in the app when I am not at home. This has made a big difference for my son with asthma! The only down side is the cost of the replacement filters (very worth it though). Hopefully they will be in stock when it comes time to change it out.

Easy set up and works great! We now have three set up in different rooms at our house. We also purchased two for my mother’s house.

The purifier continues to give off a foul, sour smell after a short time of use. I just purchased a new filter to try and resolve this issue at the end of May and by early July it was already beginning to smell this way again. Now in late July we can’t even use it anymore because it makes the room smell terrible. This seems to be a consistent problem that customers are having with Levoit’s products and they are not fixing the issues. Do not purchase this purifier. If you have already purchased the purifier don’t waste any more money on new filters and demand your money back.

[This review was collected as part of a promotion.] I never in the past really considered getting an air purifier but now that I have one I wish I would have purchased one sooner! I have a cat and it really helps with fur and keeping the litter box so that it doesn't smell in the house. I've also noticed that my allergies have gotten better. It also has an app for your phone so it really easy to set up and adjust the settings.

[This review was collected as part of a promotion.] I got this because my daughter is asthmatic and needed something in our older home to reduce the allergens and pet dander and since she really hasn't had many breathing issues. Definitely recommend ..

[This review was collected as part of a promotion.] This thing is pretty good. My dad lives with me. He had to have part of his lung removed because of cancer. I use this to help keep the air a clean as I can in the house because the filter on the furnace only does so much. This works well. I didn’t rate it higher because it is pretty loud. So we don’t use it in a bedroom, just the living room area. Sadly I don’t know how long we will be able to use it once the filter is too yucky to use because they are really expensive and we don’t get much money on disability.
