MORENTO MR2566 Air Purifier Review: cheap, compact, and decent for small rooms

I’ve been using the MORENTO MR2566 air purifier for a bit in a small flat with a cat, light cooking smells, and some mild dust allergies. I didn’t expect miracles at this price, I just wanted something that could help with pet dander and kitchen smells without sounding like a jet engine. Overall, it does the job, but with some clear limits you should know before buying.

The first thing I noticed after running it a few days in the bedroom is that the air does feel less stuffy, especially in the morning. I sneeze less when I wake up and my nose isn’t as blocked. It’s not like walking into a lab-clean room, but compared to having nothing, there is a real difference, especially in a smaller room (bedroom/office size).

Where it struggles a bit is with dust and bigger spaces. If you expect this to keep a whole open-plan living room dust-free, you’re going to be disappointed. Even one of the Amazon reviewers basically said the same: the area around it still gets dusty even on high. That matches my experience – it helps, but you’ll still need to dust normally, this isn’t a magic vacuum for the air.

So overall, my first impression is: good value if you use it in the right way (small room, run it regularly, don’t expect miracles). It’s light, easy to move, and quiet on sleep mode, which is nice. But if you’re super sensitive to dust or want heavy-duty purification, you’ll probably need to look higher up the range or a bigger model.

Given its price point and the fact it’s sitting high in the air purifier rankings on Amazon with a 4.3/5 rating, the MORENTO MR2566 offers good value for money if you know what you’re buying. You’re not paying for smart features, flashy design, or industrial-level performance. You’re paying for a compact purifier that improves air quality in a small room, stays quiet on sleep mode, and throws in a fragrance function as a bonus.

For the cost, you get: a pre-installed filter, three fan modes, timer, blue ambient light (optional), and the essential oil sponge. Most competitors in the same price range offer similar filtration but often skip the fragrance feature or the very quiet sleep mode. So if those two things matter to you, this model stands out a bit. Replacement filters will be an ongoing cost, so it’s worth checking their price before committing, but that’s the case with any purifier.

On the downside, you don’t get an air quality sensor, automatic mode, or a CADR rating that screams high power. The build is mostly plastic, and the high mode is noisy. Also, if dust removal is your top concern, some users (and me) find it a bit underwhelming. So the value really depends on your use case: if you want a cheap helper for smells and mild allergies, it’s a good deal; if you want heavy-duty air cleaning, you’ll need to spend more.

In short, I’d call it: good value for a first air purifier or a secondary unit for a bedroom or office. Not the best on the market, not useless either. It sits in that “does the job for the price” category, which is fine as long as you don’t expect premium features from a budget device.

Design-wise, the MORENTO MR2566 is pretty straightforward. It’s a white plastic cylinder/rectangular tower with rounded edges and a small footprint. Nothing fancy, nothing ugly. It blends into a corner of the room or on a bedside table without drawing much attention. If you like super premium materials and metal finishes, this isn’t it, but for a cheap purifier, it looks clean and modern enough.

The controls are on the top, clearly labeled: power, fan speed, sleep mode, timer, and light. You don’t need a manual to understand it, which I appreciate. There’s also a blue ambient light that some people will like as a night light. Personally, I find it okay, but if you’re sensitive to any light while sleeping, you’ll probably want to turn it off. Thankfully, you can disable it, so you’re not stuck with a glowing UFO on your bedside table.

The unit is quite light (about 3 pounds), so moving it from bedroom to living room is easy. One of the reviews mentioned they keep it on the bedside table, and that matches what I’d do – it’s small enough to live on a table or a shelf without being in the way. The downside of that lightness is that it feels a bit plasticky. It doesn’t feel fragile to the point of falling apart, but it’s clearly budget hardware, not premium gear.

Overall, the design is functional and discreet. It’s not an eyesore, but it also doesn’t feel like a design object. For an air purifier in this price range, I’m fine with that. I care more about noise, airflow, and ease of use, and on those points the design choices (top exhaust, side intake, simple controls) are sensible. Just don’t expect anything fancy in terms of materials or aesthetics.

Comfort with an air purifier is mostly about noise and airflow, and this is where the MORENTO MR2566 is a bit of a mixed bag. On sleep mode, it’s honestly very quiet. The spec says 22 dB, and while I didn’t measure it, it’s basically a soft humming sound. I can sleep with it next to the bed without it bothering me, and other reviewers say the same – one person said it’s “virtually silent” on sleep mode. If you’re looking for something to run at night, this part is solid.

On low, it’s still pretty comfortable for working or watching TV. You’ll hear it, but it’s more like background fan noise. The trouble starts on high mode. Several people mention it, and I agree: it’s loud. Not unbearable, but definitely not something I’d leave on while trying to sleep or have a quiet conversation. I use it like one reviewer suggested: blast it on high for an hour or two when I’m cooking or after cleaning, then drop it back to low or sleep mode.

In terms of placement comfort, because it’s light and compact, you can put it almost anywhere: bedside table, desk, floor in the corner. The air blows upwards, so it doesn’t hit you in the face directly, which I like. The buttons are responsive, and the timer is handy if you want to run it in a room you’re leaving (for example, someone mentioned using it in a craft room with resin fumes and setting the timer so it keeps cleaning after they leave).

So from a comfort point of view: very good on sleep mode, acceptable on low, annoying on high. If you’re okay using high as a temporary boost and not a permanent setting, it’s fine. If you wanted something powerful and quiet even on max speed, you’ll probably be disappointed and should look at bigger, more expensive models.

One thing that sets this purifier apart from a lot of basic models is the fragrance sponge. It’s a small foam pad where you can add essential oils. In practice, you take it out, put around 10–15 drops of oil on it, pop it back in, and then run the purifier. The fan spreads the smell around the room while it filters the air. It’s simple, but it works.

In day-to-day use, the scent is moderate, not overpowering, especially on low and sleep mode. On high, the smell spreads faster and is more noticeable. One reviewer said they wash/soak the sponge when they want to change oil, which is what I’d recommend too, otherwise the old scent lingers. The sponge is reusable, so you’re not constantly buying refills like with some branded fragrance systems.

If you’re sensitive to smells or don’t like essential oils, you can just leave the sponge empty or clean, and the purifier works normally without any perfume. It doesn’t force a smell on you. For people who like a room that smells nice (lavender for sleep, citrus for daytime, etc.), it’s a cheap way to combine diffuser and purifier in one device. Just don’t expect the same intensity as a dedicated oil diffuser; this is more of a gentle background scent.

One thing to keep in mind: if you use very strong oils or too many drops, it can be a bit much at first, especially in a small bedroom. I’d start with fewer drops and add more if needed. Overall, I’d say the fragrance feature is a genuine bonus and not just a gimmick, as long as you actually like using essential oils. If you don’t care about scents, it’s just a neutral extra you can ignore.

In day-to-day performance, the MORENTO MR2566 behaves like a simple, small-room purifier. It doesn’t have smart sensors, so it doesn’t ramp up or down automatically. You decide the speed: low, high, or sleep. I found the best way to use it is to put it on high when you actually need fast cleaning (after cooking, after vacuuming, when there’s a smell) and then leave it on low or sleep mode the rest of the time.

On high, you can feel a decent amount of air being pushed out the top, and that’s when you really notice it making a difference with odors. The trade-off is noise, as mentioned earlier. On low and sleep mode, the airflow is gentler, but that’s enough to keep the room fresher once you’ve already done a “boost” cycle. There’s also a timer that lets you set a few hours of operation, which is handy if you want to run it in a room you’re not in (like the craft room example in the reviews).

Since it’s corded electric, there’s no battery to worry about. Power usage isn’t huge; units this size usually pull somewhere around 20–30W at most, so you can leave it on low or sleep for long periods without panicking about your electricity bill. The lack of an app or smart connectivity might bother some people, but for others it’s a plus: no pairing, no updates, no cloud nonsense, just a plug and a button.

Overall, in performance terms, it’s reliable but basic. It starts up quickly, responds instantly to button presses, and doesn’t do anything weird. The main thing is to use it in a room size that matches its capabilities. If you throw it into a big, open space and expect miracles, it’ll feel underpowered. In a bedroom or home office, it’s more in its comfort zone and does a decent job for continuous, low-key air cleaning.

The MORENTO MR2566 is a compact corded electric air purifier that weighs about 1.36 kg and is roughly the size of a medium speaker (around 20 x 18 x 32 cm). So it’s pretty small and light – you can easily grab it with one hand and move it between rooms. It’s clearly designed for bedrooms, home offices, or small living spaces, not giant open-plan areas.

It comes with an original filter already installed, so you just unpack it, remove the plastic from the filter if there is any, plug it in, and you’re ready to go. There are three modes: low, high, and sleep mode. No app, no Wi‑Fi, no fancy air quality indicator. Just basic buttons and a simple interface. In one way that’s nice – there’s nothing complicated to set up – but if you like to see real-time air quality data, this model won’t give you that.

On top of basic filtration, there’s a fragrance sponge where you can add essential oils. You drop 10–15 drops of your favorite oil, and the fan spreads the smell around the room. It’s basically a mini diffuser built into the purifier. It’s optional – if you don’t want fragrance, you just leave the sponge clean or dry. But if you like light scents, it’s a nice extra, and you can remove and wash the sponge when you want to change oils.

According to the specs and reviews, it’s meant to help with smoke, pet dander, pollen, dust, and odors. From my use and what other buyers say, it’s clearly more effective on smells and light allergens than on visible dust. It also has a blue ambient night light and a timer function, which is handy when you want to run it for a couple of hours and forget about it. In short: basic but fairly complete for the price range.

On the actual job of cleaning the air, the MORENTO MR2566 is pretty solid for its size and price, but it has clear limits. Where it does best is with odors and light allergy symptoms. For example, with a cat in the house and some cooking smells, running it on high during and after cooking noticeably reduces lingering odors. The same goes for pet smells – it doesn’t erase them 100%, but the room smells fresher, and the air feels less heavy.

Several Amazon reviewers say they noticed fewer sneezes and easier breathing, and that matches my experience. If you have mild allergies to dust or pet dander, this can help make the room more comfortable. One user with resin crafts also uses it to help with fumes, which tells you people are using it for more than just dust. Just be realistic: this is a small unit, so it’s best in small to medium rooms, not an entire house.

Where it’s weaker is dust removal. One reviewer said that even with it running on high continuously, the surrounding area was still dusty after a thorough clean. I’ve seen the same thing: it reduces how quickly dust builds up a bit, but you will still see dust on surfaces and you still need to clean like normal. It’s an air purifier, not a replacement for a vacuum and duster. Also, there’s no air quality sensor or display, so you’re basically trusting your nose and your symptoms rather than numbers.

So in terms of effectiveness, I’d rate it as: good for odors, decent for allergens, mediocre for visible dust. If your main goal is to cut down on smells (pets, cooking, light smoke) and make breathing a bit easier in a bedroom or office, it does the job. If your main obsession is dust-free furniture or serious pollution, you’ll probably want a larger unit with higher CADR and more advanced filtration.
