Lavoit air purifier

We have been looking for an air purifier for quite some time, but always running into the same issues with this type of product. Mainly they are a fire hazard. Or way over priced for what you get, or un-user friendly and bulky. So, I just happened to be doing a little research and found this brand. First off there doesn't seem to be a fire hazard, the price was reasonable, you can easily move from room to room if needed, and a nice plus it was pleasing to the eye. Long story short...I took a chance and bought this one for the main traffic area and also purchased the smaller version for a back bedroom. We received both systems within a couple of days, after a brief review of the instructions they were setup and working perfectly and sooooo quite. Just as described by the seller. We've had them running constantly for about 4 days now. And we have experienced a dramatic reduction in the amount of dust and all the yucky, scary things you can't see. We aren't waking up coughing, stuffed up sinuses or a dry scratchy throat. Needless to say we are resting a lot better. In the end we liked this product so much that I purchased 2 more and probably will buy one for my son-in-law who suffers terribly every year from allergies.

Lifesaver during horrible Seattle smoke!

This product has been a lifesaver! I bought a smaller Levoit unit for seasonal allergies + cat dander and that works wonderfully. When the smoke started getting too intense in Seattle though it wasn't enough and I ordered the larger unit LEVOIT LV-PUR131. So grateful that it works as promised! I was coughing and felt like I was choking last week but this week I can finally breathe again. Albeit I still can't get out of my apartment but at least in here I'm not having chest pains. I'm interested in seeing what the filters look like next week. HIGHLY RECOMMENDED!

Annoying rattle even on the lowest setting

RATING UPDATED 02-21-18 Last week I received an e-mail from the "Levoit Support Team" regarding the concerns in my original review. I was promptly sent a shipping label for the defective unit, and notified when a new unit was shipped. The new unit arrived about four days later, is much quieter even on the 3-fan setting, and I shipped out the original unit yesterday. Is this product effective? We were accustomed to easily seeing quite a lot of particles (dust) floating across the bedroom in morning as the sun light came through the window. Now it's very difficult to see anything. Great product, great customer support. 5-star review earned. ### Started to hear a rattle from inside the unit less than a month after first use, and I'm assuming the noise is coming from a fan. It rarely ramps up from the lowest setting, which causes me even more concern - what will it sound like a month from now or when it speeds up to filter more particles. Otherwise the unit appears to work fine. Just to be fair, I'll give it another few days. If the noise persist, it's going back.

Update: Important Tip

Just received the purifier today. It was easy to set up and right away it began working. The different options are very nice. The fan on high is very quiet so that is a plus. Will have to see within the next few days if I notice a difference in the air quality within my condo. Several months later...When I placed new filters into the air purifier, shortly thereafter the "change filter" light started blinking. Now I changed the original filters before the change filter light came on because I thought they looked in need of replacement. Every effort to reset the purifier was unsuccessful. Finally I emailed the seller and they provided excellent customer service. After going through the usual "Do you where the reset button is, etc.," the rep suggested I switch the purifier to auto mode while the purifier is running and then push the reset button. Voila! The light quit blinking immediately after blinking for a number of weeks. Tip: If the suggested steps to reset do not work as in my case, select auto with the machine running and hit the reset button. That should turn of the blinking light. I will say it is not clear to me why Levoit cannot design the reset button where it is more easily accessible or at least put a removable cover over the reset button. Nevertheless, I am extremely happy with this air purifier. This remains my favorite air purifier by far.

Change filter indicator is apparently extremely conservative.

Had an unpleasant surprise when my purifier, which has been working fairly well in the two months I've had it, popped up the "change filter" indicator light on me. A representative from the company told me that it's based on running time, not the condition of the filter, so if the air quality is still good it can be reset. Upon checking, the filter was still in pretty good shape, so I'll keep resetting and see how long until the performance degrades. It's still doing a fine job cleaning the air and I haven't had any other issues with it.

I received my machine, followed the set up directions ...

I received my machine, followed the set up directions, and the machine will NOT power on. I have tried 3 outlets and no luck. I'm not very impressed right now! **UPDATE** The customer service was fantastic! They sent out a new machine and it has been perfect since. I put the unit in my bedroom because it doesn't really make a lot of noise, so my sleep is not interrupted and I experience clean air. My allergies have seen a dramatic improvement at night! Thank you tot he Levoit Team for being so responsive!

Not well made

Works fine right out of the box. Not sure how well its cleaning the air cause honestly I cant tell a difference. However the filter gets dirty so i know its doing something. Now for the BAD. It started making a terrible noise, like the fan was hitting something. I took it apart and the nut had backed off the main shaft and was bouncing around inside the machine. The hamster cage had been rubbing the inside of the front case. I repaired it with some locktite and it works fine now. Would not buy again. EDIT: the company reached out to me and shipped me a brand new unit. Excellent customer service and they stood behind their product, very impressed!

Got Rid of Neighbor's Cigarette Smoke!

I live in a condo with a smoker next door and was tired of smelling his second hand smoke and even getting a raw throat from breathing that garbage into my lungs. I would usually open a window and let the furnace fan run to circulate the air, but it's been too cold in Wisconsin to do that. I was a bit reluctant to buy this as my condo is open concept with no separate rooms on the main floor (except a half bath) and open staircases to the basement and upstairs. I received this yesterday, set it up, turned it to high speed, and the cigarette stench was gone in 5 minutes and my throat isn't burning any more. I'm sure with the way my condo is set up, I'm not getting the full benefit of this air purifier, but it is doing what I needed it to do. Even running at high speed the fan is not overly loud. Highly recommend this air purifier.

Love it and it works really well for cigarette smoke

I just moved in with friends that smoke and have many dogs and I also have 3 caged birds and it seems to work great with the extra smells and keeping it nice in the room that I am staying in. So far I am very glad that I purchased this air purifier since I needed it for the cigarette smoke mainly and it is cutting down the smell to not even having that smell in the room I am staying in. I would like to see how it will take before I have to change out the filter. That will certainly make it or break it. I did already purchase a new set of filters, to have on-hand when I need to change them out.

I noticed significantly less dust in the room

I almost left them a bad review... So I plug in the unit and everything looks great: it's super quiet, everything as described. I put it in the "auto" mode and the light is blue, which indicates that air quality is good. I live in Los Angeles and with all the talk about how our air is terrible, I expected to see the light to turn--at the very least--green or yellow. So I was just wondering if the thing was even doing anything? I left it on for another day. The first time I realized it's actually working was when I was cooking fish and there was quite a bit of smoke in the room. The light went from blue to green to red in a matter of minutes and the unit became noisier and it was obvious it's working hard. As soon as the smoke cleared, it went back to it's normal, quiet, state. But the best came in about three days. I noticed there was significantly less dust on my TV stand. Normally, it's all dusty in 3 days or so. There was hardly any dust in a week. So, it definitely works in filtering out dust, which is a win-win in my book: less cleaning and cleaner air to breath!
