Levoit PlasmaPro 400S Smart Air Purifier

I have a small condo, upstairs unit and the downstairs neighbor cigarette smoke is coming in our condo. I have 6 air purifiers all on the highest settings and this unit DOES NOT REMOVE THE CIGARETTE SMOKE! It is extremely loud on the highest setting. This unit is new. I do not recommend buying this product.

Impressed how quiet it is!

We use ours daily and especially after we cook in our apartment. I love this. Our cat struggles with allergies and it has improved the itchiness he has.

The plasma pro technology Neutralizes and breaks down particulate matter, odorous gases, and other aerosols not visible by the naked eye!

Very quiet and easy to set up

I love the ability to control thru the app!! And the Lock Screen and turn screen off feature (I have kids lbvs) ; it truly helps and even if air quality is good we use it as a fan def cools the room. Oh and I priced match with Amazon!

It truly hurt to spend this amount on this item but it is most definitely worth every penny. My filter needs to be replaced and I have asthma/bad allergies. I’ve noticed a huge difference the last few nights it’s been off in my room.

4 stars because although we love everything about this air purifier, we feel the packaging can be considered a bit deceptive if you don’t read all of the start up instructions. The filter is already in the air purifier when you purchase but it’s covered in plastic. So the purchaser has to open up the box, open up the air purifier and remove the plastic from the filter before reinstalling and operating it. If you’re good about reading instruction then you are safe but some people are not good about reading the instructions.

It doesn’t help in a connecting condo where the others smoke. My condo still smells of smoke. Was hoping this would help in a small living area…..

We have two of these and they work great. I really like that you can see the level of particles on the top of the filter. Replacement filters are 50 dollars are usually have to be replaced about every 3-4 months. Got this during the Canadian fires and was surprised how high the particulates were upon getting it started. Feel much better about the baby being upstairs with clean air.

[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.

I’ve had this for about 6 months now. I wanted to wait a while before I reviewed it so I could get through my heater and air conditioner going. I mainly got this because I’m in an apartment and my neighbor below me thinks her apartment is infested with all that is evil so one day there is smudging and the next is garlic sprays and the smell is just too much. So this has pretty much eliminated that problem. The garlic is still lingering sometimes but I can deal. My family also all has allergies and this year they have been horrible so this purifier has saved us when we are home. We can sleep, taste our food, see clearly. It’s pretty nice. I also noticed when it started to warm up that I was starting to see fruit flies in the filter. I vacuum it regularly. I wasn’t expecting it to catch any bugs. Sure enough, it sucks those little fellas right in too. This really was a solid purchase.

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 ..
