Quiet
These are super quiet and I feel like they do a good job. I actually bought two more because of how well they run. I’ve had them now for a couple years and they still run great.

Worth the investment for a near dust-free home.
One of those things you don’t realize you need until you get it. The amount of dust in a house this thing will cut down on is tangible within the first month. We now have one on both floors of our house and the filters on these things speak for themselves when you change them. Feels much cleaner in our house now because of these. No noticeable uptick on electric bill either and we run them 24/7.

Great for small rooms

Morento Purifier
I am only giving 4 stars cos 2 out of the 5 purifiers I bought from this seller has power adapter issues which caused the power to flicker and not power on the unit. Seller was not very helpful at replacing the adapter so I purchased adapters from a different seller and the units worked great now. Overall this is a great purifier and does its job especially for smoke and pet hair. My only complaint is their adapter does run a little hotter than I am comfortable with and I wished the seller would quality checked their adapters or make better adapters cos I was not happy when 2 of my units had bad adapters that stopped working, one in the first week and one after 2 months. Other than that, this is a great purifier.

(UPDATED REVIEW) Some thoughts on filters, electric bill, and company integrity
UPDATE (December 2024): (I've raised my rating from 4 stars to 5 just because the company seems to great. My little learning curves noted in the original review still stand, but the company makes up for the little insufficiencies in the manual.) I realized that much of the dirt in my house that you can write your name in is coming from ongoing construction across the street from my house where dirt and gravel dust is being constantly stirred up. That's obviously a gripe for a different forum. NOTHING can keep up with that amount of debris in the air, but this little machine is doing its best, and I DO believe it's making a difference. I just have to bang out the filters more often than the average person. LOL I've had two mechanical problems, which the company responded to promptly and efficiently. First, a few months after I bought it (and outside the return window, if I recall) there seemed to be a sensor problem because the because the light indicating high debris levels remained red 24/7 (which I mentioned in my original review) even in the middle of the night when neither dogs nor backhoes were stirring up anything. New filters made no difference, it stayed red. I contacted the company, and with minimal fuss after my explanation, they shipped me out a replacement unit, allowing me to keep the first one until the new one arrived. (It still ran, it just had a faulty sensor, so the Automatic setting caused it to run on high constantly.) The new unit is still going great. Second mechanical issue happened just recently (Nov/Dec 2024). The display lights were flashing weakly every 5-10 seconds, and the unit wouldn't turn on. I contacted Morento, since this wasn't in the trouble shooting guide. They answered quickly, and said it sounded like a power cord issue, and they would ship me one (at no cost to me). It arrived today, I plugged it in, and everything is back to normal again! This just seems to be a great company. Very responsive to customer issues, and looking to make things right rather than pass the buck. So rare today, and very much appreciated! Updates on functionality, etc... Still no hit to electric bill after running it 24/7 for the last 9 or 10 months. Yay! I make the filters last longer than my originally reported 6 weeks by removing them and taking them outside to bang the dust off every week or two. I do still recommend creating your own pre-filter as described in my original review below, in order to catch larger particles like pet hair (or backhoe dirt...). This little machine really should come with a pre-filter. It would only add like 50 cents to the price. LOL ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ORIGINAL REVIEW--4 STARS (February 2024): I like the machine. It's reasonably quiet. We keep it in the living room, near the front door because I have 3 young pitties who have made a desert out of my formerly grassy yard, and drag in pounds of dirt every day after wrestling and running all day long. Before getting this air purifier, I could write my name in the dust only a day after cleaning... Revolting... W... T... F. Now, it takes a week to 10 days for that to happen. LOL My biggest disappointment is the filters. The instruction manual notes that there is a light that will come on when it's time to change the filters, but I have concluded that it's time-based rather than dirt-based. The running meter on the front has been red and in the several-hundred level for a week or two, and it took us a while to realize that it was at that level 24/7, not just during busy time periods in the house. And yet, the "change filters" light STILL hasn't come on. I have removed all the filters and pre-filters, and banged or shaken them off outside, and even vacuumed them. But the meter is still red and in the 400s. =O The filters are easy to install, but they won't last any 6 months for our dirt and dust level. I'm already replacing them after only 6 weeks, which seems kind of ridiculous. I bought a roll of foam to make my own pre-filters since the included filters didn't have them. (I don't know if links work properly in reviews, so the foam I used for the pre-filters is: "Cut to Fit Foam Pad Pre Filter, Air Purifiers Filter Replacement, Compatible with Most Air Conditioner, Trash Cans, Dehumidifier, 39 x 16 inch" made by Wintcomfort.) This pre-filter foam catches larger bits of dirt, pet hair, etc, so the expensive inner filter doesn't get clogged up so fast. It can be rinsed or vacuumed and reused indefinitely. So yeah... the instruction manual says to clean the filters occasionally, but I guess that will vary with your home. Some people might be fine doing this monthly, bi-monthly, or never, before installing a new filter every 6 months. With our apparently filthy house, when I replace the filters when the new ones arrive in two days, I will try cleaning all the filters weekly or biweekly. If I think about it, I'll come back in a few months and report on how it's going. I did want to report, too, that my electric bill has taken NO hit at all. I have a dehumidifier that raised my electric bill substantially when I ran it only during daylight hours during a particularly humid summer a few years ago, so I was kinda worried about this machine. But there's been pretty much zero difference in my bill and this thing runs 24/7 on the auto setting. So far, I like the machine! I only took off 1 star due to the filter stuff, lack of good instructions on how often it might need cleaning, lack of its own pre-filter and the cost of buying my own foam, and the fact that the "change filter" light seems to be time-based (e.g. 2000 hours) rather than gunk-based. It's easy enough to add "change filter" to my calendar app, so a time-based reminder light is kinda of useless. A gunk-based light would've been WAY more helpful. I guess the gunk-based reminder is when the meter stays red even in the dead of night when everyone's asleep, if you happen to notice it when you get up to hit the bathroom. LOL

Good buy
Works well. I have 9 large dogs that come in and out of house - i have 2 of these to cover the roughly 2000 square feet that they are able to be in and works well to keep dust and odor down.

“Your House Has No Pet Smell at All.”
I LOVE this air purifier. I love it so much, I’ve purchased several units to keep around the house. They are virtually SILENT when running on automatic. I run them 24 hours per day, and you can’t hear them at ALL unless you are directly next to them or run them on a higher setting (there are four). When setting a higher fan speed, there's a built-in timer that switches back to silent/automatic after a certain amount of time. I own a smaller version from the same company that’s weirdly louder than this unit. There’s a colored ring and number on the display so you can always have a sense of how “clean” the air is. There’s also a filter life metric so you don’t have to guess when they need replacing (and there’s always visible dust and dirt when I do). Haven’t noticed any crazy energy bill spikes as a result of using these. It’s somewhat large, but aesthetically sleek. Aside from the colored ring, it’s not distracting. If you keep it in a bedroom, the light may be a distraction if you prefer pitch blackness. I haven’t looked into whether or not it can be turned off because it doesn’t bother me, but if it can, that makes this an 11/10. EDIT: It DOES have a night mode that runs on an even lower speed and turns off the colored light. There is a button with a little moon on the panel. I just never really bothered to use it. I think you have to turn it off manually, unlike the higher fan speeds. The biggest praise I can give to this product is I was told recently that our home has no cat smell at all, and we have two. I’m paranoid about odor, particularly when we have guests over, and that was basically the highest compliment I could receive. I’m legitimately obsessed with these. The ONLY criticism I have is that the power cord plugs into the side of the unit as opposed to the back. I wish it would be moved so that the cord could be completely hidden.

fait parfaitement bien son travail, le réservoir est grand (1,5 litre) ce qui permet de le laisser une journée sans s'inquiéter. Acheté l'an dernier en novembre, installé dans un local rendu très humide en raison des nombreuses pluies, le réservoir s'est rempli en 3 heures...... je recommande cet article

Lo coloque en un restaurante en donde pese a las salidas de aire existentes siempre quedaba algo de olor a comida en el área de piso. Desde el día 1 el olor se elimino y el ambiente se siente mucho más fresco. El sensor de ambiente funciona muy bien y se.puedr probar cambiándolo de lugar a las áreas más densas. Excelente compra.

The MORENTO air purifier has been a great addition to my home, especially for larger rooms. It moves a surprising amount of air for its size, and the real-time PM2.5 display makes it easy to see when the air quality changes. I like being able to glance over and know whether it’s actually doing something instead of just running in the background. The noise levels are very manageable — on low or sleep mode it’s quiet enough for a bedroom, and even higher settings aren’t overly loud. The design is simple, modern, and doesn’t take up much floor space, which is nice considering the coverage area it can handle. The filter is easy to access and replace, and the unit gives clear reminders when it’s time for a new one. I also appreciate the different timer and fan settings, which make it easy to adjust for daytime use versus nighttime. Overall, it’s an effective purifier that noticeably freshens the air, runs quietly, and covers a large area without being bulky. A solid choice if you’re looking for cleaner air in a bedroom, living room, or any larger space.
