Quiet and efficient!
I'm not sure why anyone would want to return one of these. It's quiet and efficient. The power supply is external and plugs into the wall, which is slightly more cumbersome, but the cord is very good. The filters last a long time! There are two of them, so it can take air in from both sides. I did have a power supply go bad, but the manufacturer was responsive and sent a new one quickly. Very satisfied.

Amazing so far!
So far so good! Have had this in the bedroom for just one night and felt a difference when I woke up. No stuffy nose or itchy eyes! I’m a light sleeper and I was worried about the sound and light annoying me in the night but the night mode turns the light off and lowers the fan speed. Runs very quiet and didn’t keep me up at all. Would highly recommend to anyone with allergies to get this and you will notice a huge difference.

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

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.

Purificador de aire
This air purifier has been a huge improvement to my bedroom. Since I started using it, the air feels much cleaner and fresher, especially at night. Its design is modern and elegant, blending seamlessly with any space and not taking up much room. What I love most is how quiet it is, perfect for uninterrupted sleep. The digital panel is intuitive and allows for easy adjustment of the settings as needed. Plus, the indicator light adds a touch of modern technology and practicality. It's perfect for people with allergies, dust, or simply for anyone who wants to breathe cleaner air at home. Without a doubt, it's an excellent investment for everyday well-being. I highly recommend it.

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.

Macht genau das, was er soll. Die Luftqualität hat sich spürbar verbessert. Gerade mit Katzen und Katzenhaarallergie ein unerlässliches Produkt. Einfach zu bedienen, nicht zu laut.

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.
