LEVOIT Air Purifiers for Home Large Room Up to 2933 Ft² With HEPA Sleep Mode, AHAM VERIFIDE, Smart WIFI, PM2.5 Monitor, 3-in-1 Filter For Smoke, Pet Allergies, Dust, Alexa Control, Core 600S-P, White

We purchased one of these on sale in the hope it would help moderate the severity of pollen season in upstate NY and the dander generated by two large labradors. It has a nice, clean look and small foot print, which we feel is important. The HEPA filter was shipped inside it in a bag that needs to be removed but doing so was incredibly quick and easy to do. Twist the top a quarter turn and place to one side. Lift out the filter, remove the bag, lower the filter back in using the two tabs provided on it for that purpose, lift the lid back on and quarter twist to close. It takes 2 mins. Then its' plug-in, turn on and choose ""Auto" or a fan speed using the touch sensitive panel on top. You can control it from your iphone if you're into that but it certainly isn't necessary. The first thing we noticed is how quiet it is. Effectively soundless in sleep mode and at fan speed 1. Barely noticeable at fan speed 2, unless you're right next to it, noticeable at fan speed 3 when you are in the same room as it but not obnoxious. Noticeably louder at fan speed 4 which should be considered a 'Turbo" mode. Then we noticed the impact of running it - vastly reduced swelling of the eyes and sinuses of those suffering from hay fever and a significant reduction in the doggy smell of our labradors. It works really well. We have taken advantage of the ability to control this by iPhone to set a schedule where it automatically runs in sleep mode (low, continuous fan) from 10pm to 5am. Then at fan speed 2 from 5am to 5:30am, ramping up to fan speed 3 from 5:30am to 8am before switching to auto from 8am to 10pm. Because of the relatively severe allergies suffered by a couple of our family members the P2.5 micron threshold is set to 2 ug per meter cubed and this filter has been able to attain that incredibly low level with that schedule within a few hours of all windows and doors to the outside being closed to the 1800 sq. ft area it services. At this point we have an oasis for our hay fever sufferers to return to each evening and it's made an incredible difference to their comfort. Do they still take Claritin or Allegra during pollen season? Yes, we've found it necessary to deal with the pollen at work and in the garden. Are they doing better than they were before we got this filter? Yes, the continuously swollen and itchy, weeping eyes are gone. The inflamed nasal passages are gone. Their sleep deprivation is gone. Their quality of life has improved dramatically. We had no idea how dramatic an impact adding a quality, appropriately sized HEPA filtration system would have. This unit is rated for something like 3000 sq. ft. We're using to control air quality in a 1800 sq.f.t open plan area and its doing a great job of that without having to run the fan at high speed for prolonged periods of time. We've had this for several weeks now and experienced 1st hand how well it can deal with really terrible air quality when the smoke from the fires in Quebec blew into NY. Opening the door to come into the house with the shopping during the worst of it briefly dropped the air quality from a PM2.5 of 001 to as high as a PM2.5 of 185 within 12 feet of the door. This was then quickly reduced to a PM2.5 of less than 20 in an hour and back to 001 in about 2 hours after the door was closed. The outside airs PM2.5 was apparently North of 300 at this time (sources accuweather and the news), the air was literally a hazy brown like smog and this filter was able to detect it, automatically adjust its fan speed to clear it and maintain perfect air quality in the house. Does it work? Absolutely, quietly and brilliantly. Would we buy this again? Yes, in fact we have so that we can control the air quality for one of our allergy sufferers in another area where they have to spend prolonged periods of time. That one's been in place for about 3 weeks and has done exactly what we hoped it would do - improve the quality of life at work in a 7000 sq.ft. open plan office area. Now this is well beyond the manufacturers claimed coverage for a unit and it looks like they're right based on who's apparently benefiting and who isn't but here's the important point. The benefits to the workforce have been so noticeable to management they're now considering upgrading the offices HVAC system to include HEPA filtration. I think that speaks volumes.

These air purifiers are excellent. They operate quietly and they are quick to respond to fumes coming from the oven and other sources of reduced air quality. They are a great addition to a kitchen dining area. Our stove vents don’t work well, but this purifier cleans the air efficiently.

I don't often write reviews but in this case I wanted to as the unit met my expectations.The purifier (Core 600S) comes as advertised. The filter is enclosed in a plastic bag, which must be removed before turning on the unit. The instructions are clear and easy to follow to open the top of the purifier, and replace the filter once the bag has been removed from around it. The unit is very quiet when in "Auto" mode, if you manually adjust the fan speed to max, it becomes noisy, but not unbearably so. I generally only use the max speed if I notice the reading on the screen going high, and then slip it back on auto once things are under control. The unit is app controlled with speed control, scheduling, power and filter life details all available therein. From the moment I purchased this and turned it on, I noticed a drastic improvement in the air quality in my home. My wife and I are both sinus sufferers, and since I've bought this, she no longer walks through the house sneezing during days of high Sahara dust and smoke, and I no longer wake up with watery eyes. The unit is very efficient and works to keep my entire home clean. I have this unit in my living room and doors of adjacent rooms are kept open during the day and the purifier easily manages to keep the air quality in an excellent state throughout all of them. The unit is easy to clean. I wipe the outside with a soft cloth and vacuum the base on the inside to pick up any heavier/larger pieces of dust that accumulates under the filter. I purchased it at the beginning of July, and am now in line for my first filter replacement after about 6 months, and no dip in performance. The filters are a little on the expensive side, but I'm happy with the performance of the purifier and don't mind paying the price to ensure the same quality in my breathing air. I hope this was helpful to someone out there.

Happy with this so far. I have two of the Core 300’s. The 400 seems to pull a lot more air and a lot less fan noise. I was surprised at the size difference between the two filters the 400 is almost twice the size. It is definitely better for larger rooms but the 300 is nice for smaller/medium size rooms. This model seems to be the sweet spot of value with quality. I love the smart capabilities so I can schedule different fan speeds throughout the day. For example, I set it to run on high for an hour mid-day and then again before I get home from work. Having multiple purifiers throughout the house definitely helps keep the air quality more consist, especially in spaces where airflow is minimal because of room layout.

To start with, I have 2 of these in the 300 series. I liked them so much I ordered 2 600s after having my other 2 since 2021. Here is what I like about the 600: very powerful. WiFi and app control. Can make a schedule for run times and speeds and on your choice of days a week. Seems to work good. I’ve only had them a day so far. I’ll update later if something changes. Now for the not-so-good: it has 4 fan settings. Speed 1-2 are quiet and probably pull the same air as my 300s do. On speed 3 it gets louder so much that if you’re in the same room you have to almost speak over it to hear eachother. On speed 4, forget it; you can’t hear eachother talk. I mean I guess it’s good it pulls that much air to clean, but it’s annoyingly un-ignorable. So I set this 600 to be at speed 4 while I’m at work and speed 2 while home. Works for me. It has an auto function, but I don’t trust auto. If you need an air purifier in your home, you need to run it at full speed or you don’t “need” it. The last con- the filter does not seem to have the carbon the other filters have to trap smell. I plan to order “pet”!filters after these are ready to be replaced. Overall, I can’t say id recommend it yet. I need more time with it to know if it’s worth it. This one is too expensive to “see if I like it” the only reason I bought it was that I am very happy with this brand 300 series. The 300, at best can cover one normal size bedroom only. And if you have pets that are in that room a lot, you’ll need to change the filters every 3 months- not every 6-12 months like advertised. I have 3 dogs and a cat, so that’s my experience. And I have other brands that are the same, it’s not this style or brand. It’s all purifiers.

Really smooth and quiet operation with a well put together app which was very important to me other than actual performance and loudness of the unit. The app clearly displays the PM1, PM2.5, and PM10 currently in the air rather than the generic good, fair, poor. The unit also looks great in the room, and fits well with most decor. It is a bit large but that's just physics. It needs to be a certain size to achieve the performance it touts. A bit pricey at normal price but it comes on sale from time to time bringing the entry price way down. It remains to be seen how effective buying third party filters will be since their first party filters are quite expensive. But we shall see. All in all a great unit.

So I was looking for an air filter for my Florida room, which is the only room in my home where I smoke cigarettes. In the non summer months I just keep all the windows open and the room airs out. But in the summer months when the humidity is unbearable down here, I have to run an air conditioner in the room. Which means I have to close the windows, which means the cigarette smoke doesn’t air out. So it’s a dilemma for me. It’s either sit in the room sweating and uncomfortable in the humidity with the windows open and let the smoke out - or shut the windows and use the AC and have the room filled with lingering smoke. Neither of which are ideal options. So I figured an air filter might be a solution. I found though that it wasn’t that simple, because then it turns into which air filter to get that’s actually going to work, without breaking the bank as well. I was trying to find the best air filter to solve this issue within a reasonable price point. I really did not want to spend more than maybe $200 or so. Before finding this one, I tried 2 others that literally did nothing, that were admittedly a bit cheaper than this one. Then I found this one, and it was delivered the same day. I got this one today, hooked it up and did a real time test. I put this unit on a stand in a good spot in the room, set it up, plugged it in, and the air quality in the room was reading very good - indicated by the blue ring and very low number on the screen. I then closed all the windows, turned on the AC, and then lit up a cigarette. I purposefully blew the smoke right onto the unit every time I took a drag and exhaled. I knew immediately that this was going to work when this filter INSTANTLY detected the cigarette smoke, and the blue light ring which means excellent air quality, turned red, and the air quality numbers on the screen jumped from around 20 (which means excellent air quality) to about 900 (which means the air quality is horrendous). Once the machine detected the smoke, it immediately began filtering it out of the air, and I literally sat there and watched the numbers on the screen going down in real time as it was removing the smoke. The red lights also gradually turned to orange, then green, then I left the room for 10 minutes. When I came back in the room (which is not very big, maybe 600 sq ft tops) there was no visible smoke in the air, and the light ring was back to blue, and the air quality numbers were back well below 30. So this had cleaned the air and removed all the smoke. This machine is beyond impressive. Now, I will say that even though the smoke was gone in the air, there still was a lingering faint odor of cigarette smoke in the room. But I also did not give the machine a full hour to run for the test. My thinking is that if I did, it would have removed the odor as well in a bit more time. Given what I watched this do in the short test though, and how it performed? This air filter is truly remarkable, and I’m beyond happy with this purchase so far. I would highly recommend this product for anyone trying to deal with any kind cigarette, or other kinds of smoke in a dwelling of any kind. A ++++++

Just received the Levoit Everest P Smart air purifier 3 hours ago. I set it up right away. The air on my living room is s0o fresh within the hour of starting it. I absolutely love it! You control it from your phone or from the unit. It tells you your air quality. If you set it on auto it will automatically adjust until your air is great. It will back off once your air gets great. It's s0o quiet on 1 or 2. Three is still quiet. Four and turbo are understandably a little tv adjustment for sound but not so bad.... expected. Size is better than I thought. The filter is very good quality. Seems like a good amount of charcoal in the filter. More than other ones. Brightness..... what brightness ;) Ease of use is simple. Fresh air is WONDERFUL! Did I say, I LOVE IT! I bought another already. I hope they stay great! My only complaint and it's a big one is I paid $499.00 for it and the price dropped to $399 the very next day. That didn't seem right.
