Does not remove cigarette smoke!
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.

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.

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.

READ THE START UP INSTRUCTIONS
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.

Not good for cigarette smoke
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 appreciate you sharing your experience. Our units feature a 3-stage filtration system including a high-efficiency carbon filter to help remove odor particles. For best results, we recommend minimizing the source of the smell as best as possible first as the air must also pass through the filters a few times. To rapidly purify the room, we recommend running the unit at a higher speed with the doors and windows closed. If you have any further questions or concerns, please reach out to us directly. Our email address is support@levoit.com; our hours of operation are from 9:00 AM to 5:00 PM PST Monday thru Friday.

Best HEPA purifier
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.

Works Excellent!
[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!

Great for allergies and asthmatics!
[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!

Strongly recommend for those with allergies!
[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.

Best purchase ever!
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.
