Evalit ET066 Air Purifier Review: a big-room unit that quietly gets the job done

I’ve been using the Evalit ET066 air purifier for a few weeks now in a pretty dusty flat with a dog and seasonal allergies. I didn’t expect much because it’s from a brand I’d never heard of, and it’s cheaper than some of the big names. But I wanted something that could handle a whole living room plus some hallway, not just a tiny bedroom. On paper it covers up to 2200 ft², which sounded a bit optimistic, so I was curious to see what it really does in normal daily use.

The first thing I noticed after a couple of days is that the air in the room feels less heavy. That’s not very scientific, but it’s the same feeling I’ve had with more expensive purifiers: less dust floating around in the sunbeams, less stuffy nose in the morning. I also have a dog that sheds and brings in outside smells, and the usual “wet dog” smell after a walk in the rain faded quicker when the purifier was running on medium or high.

I mainly used it in the living room (roughly 300 ft²) and occasionally moved it to the bedroom at night. It’s not tiny, but it’s still manageable to carry from one room to another. I played around with all three speeds, auto mode, sleep mode, and the fragrance function. The PM2.5 display and colour ring gave me a rough idea of what it thought of my air quality, especially when cooking or vacuuming stirred up dust.

Overall, my first impression is that it’s a pretty solid workhorse for the price. It’s not perfect: the high speed is a bit loud, the plastic feels basic, and the fragrance feature is more of a small extra than a real diffuser. But if you’re looking for something practical that cleans the air without costing Dyson money, this one holds up better than I expected in real life use.

For what it costs, the Evalit ET066 sits in that mid-range spot where you’re not paying for a big-name logo but you still want real performance. You get a large claimed coverage, proper HEPA and carbon filtration, auto mode with a PM2.5 sensor, sleep mode, pet mode, timer, and a washable pre-filter. You don’t get Wi‑Fi, an app, or fancy design, but honestly, for most people that’s not essential for an air purifier.

Compared to cheaper small units I’ve tried, this one clearly moves more air and deals better with bigger rooms. Those little desktop purifiers are fine for a tiny bedroom or office, but they struggle in a living room, especially with pets. Here, you actually feel the difference in a 300 ft² space after an hour on medium. That alone makes it good value if you’re targeting larger rooms. Against premium brands like Dyson or Philips, you obviously miss out on the brand name, advanced app features, and sleeker materials, but you’re also paying quite a bit less.

Running costs matter too. The 33W power draw is reasonable, especially if you mostly use low or auto mode. The washable pre-filter helps keep filter costs down over time. You will still need to buy replacement filters, but not as often as with units that don’t have a pre-filter catching the big stuff. If you’re on a budget and want something that actually cleans the air rather than just looking techy, this is a pretty solid compromise.

For someone with pets, mild to moderate allergies, or just a stuffy flat, I’d say the price-to-performance ratio is good. If you absolutely want app control, integration with Alexa/Google, or a very stylish design, you might want to look higher up the range and pay more. But if your main goal is cleaner air in a big room without overspending, this model makes sense financially.

Design-wise, this is very much a “white plastic box with vents” type of product. Dimensions are about 31.5D x 16.6W x 41.3H cm, so it’s tall and slim rather than a big cube. That shape helps if you need to tuck it next to a sofa or in a corner. It’s not going to impress anyone visually, but it also doesn’t scream for attention in the room, which I actually prefer for this kind of appliance.

The build quality feels decent but nothing more. The plastic is light, slightly glossy, and if you tap it you can tell it’s not premium. That said, there are no weird gaps, no rattling panels, and the filter compartment opens and closes without drama. I moved it around a fair bit between rooms and it held together fine. It’s also light enough to carry with one hand, which is useful if you’re switching it from living room to bedroom daily.

The top control panel is clear: icons are straightforward, the touch buttons respond reliably, and the PM2.5 reading is easy to see from across the room. At night, the display is a bit bright on normal mode, so for the bedroom I usually switch it to sleep mode, which dims things down and slows the fan. The child lock is a nice touch if you have kids who like pressing random buttons; a long press locks everything so they can’t mess with your settings.

One thing to note: there are no wheels. On carpet or if you want to slide it around a lot, that might be a bit annoying. You have to lift it. Also, the power cable is fine but not especially long, so you might need an extension lead if your sockets are badly placed. Overall, the design is practical and low-key, not stylish, but for a device that mostly lives in a corner doing its job, I’m okay with that.

One of the selling points is the built-in aromatherapy compartment. In practice, it’s a small tray or pad where you can add a few drops of essential oil. Air flows over it and carries a bit of scent into the room. I tried it with a basic lavender oil in the bedroom and a citrus oil in the living room to see how much difference it makes while the purifier is running on low and medium.

On low or sleep mode, the smell is there but pretty light. You notice it when you walk into the room, but it’s nowhere near as strong as a dedicated diffuser or burning a scented candle. On medium, the scent spreads a bit more, but it also fades faster because the air is moving quicker over the pad. I found I had to reapply oil more often than I expected if I wanted to keep the fragrance noticeable for more than a few hours.

For people who are sensitive to scents, this is probably a good thing: it doesn’t blast the room with perfume. It’s more of a background smell that makes the room feel a bit fresher. For example, after cooking something with a strong smell, medium speed with a bit of citrus oil helped mask the leftover food odours while the filter did its job. But if you’re expecting a spa-like aromatherapy experience, you’ll be disappointed; it’s just a small add-on to the main air cleaning function.

One practical note: don’t overdo the oil. The manual suggests a few drops, and that’s accurate. If you pour too much, the scent becomes a bit heavy close to the unit and I’d also be worried about residue building up inside over time. Overall, I’d call the fragrance feature a nice-to-have extra. It smells nice when used lightly, but it’s not the reason to buy this purifier. Think of it as a small bonus, not the main event.

I obviously haven’t had this unit for years, but after a few weeks of daily use I can at least talk about how it feels in terms of durability and maintenance. The casing is light plastic, but nothing feels like it’s about to snap off. The front panel removes easily to get to the filters, and the clips haven’t loosened with repeated openings. I’ve moved it room to room quite a bit, and there are no new rattles or odd vibrations.

The washable pre-filter is a big plus. It catches hair, fur, and larger dust, and you can just rinse it or vacuum it. This should help the main HEPA and carbon filter last longer, which means fewer replacements. The main filter is not washable (like most HEPA filters), so you’ll eventually need to replace it. The exact replacement cost will depend on where you buy it, but in general, being able to clean the pre-filter regularly is a solid way to stretch the life of the expensive part.

In terms of wear, the fan still sounds smooth, no grinding or odd noises, and the touch buttons respond as well as on day one. The PM2.5 sensor also still reacts quickly when I test it with smoke or spray, so it hasn’t clogged up immediately. Obviously, long-term, sensors can drift, but for now it’s doing what it should. The fact that it’s a relatively simple wired unit (no moving parts apart from the fan, no battery) also means less to break.

If I had to nitpick, I’d say the plastic could scratch if you’re rough with it, and I wouldn’t keep it somewhere kids can kick it all the time. But as a normal home appliance that sits in a corner and gets moved occasionally, it feels sturdy enough for the price bracket. As long as you clean the pre-filter every few weeks and replace the main filter when needed, I don’t see any obvious reason it wouldn’t last several years.

Performance-wise, you mainly notice three things: how loud it is, how strong the airflow feels, and how smart the auto mode actually behaves. On low and sleep mode, the noise level is very manageable. In the bedroom, sleep mode is quiet enough that I forgot it was on after a few minutes. It’s more like a soft fan noise than a harsh whine. On low in the living room, it just becomes background noise and doesn’t bother conversation or TV.

On medium, you definitely hear it, but it’s still okay for daytime use. This is the setting I used the most when I wanted a balance of speed and comfort, for example after vacuuming or when the dog had been running in and out. High speed is where it gets a bit loud. There’s a clear airflow whoosh, and you won’t want that on while you’re trying to sleep or watch a quiet movie. That said, on high you feel the air moving strongly from a couple of meters away, so it’s useful if you want a quick clean after cooking or if someone smoked nearby.

The auto mode is actually pretty handy. The purifier starts in auto by default, reads the PM2.5 level, and adjusts the fan. In a normal day with windows closed, it mostly sits on low or medium. When something spikes the pollution (cooking, sprays, opening a window on a busy street), it bumps up to medium or high for a while. This saves you from constantly changing speeds and probably also saves some power compared to leaving it on high all day.

There’s also a pet mode and a timer (1–12 hours). The pet mode feels similar to running it on a steady medium with some tweaks; I mainly used it when brushing the dog or after he’d been shedding a lot. The timer is straightforward: set it for a few hours before bed or when you leave the house and it shuts off automatically. No bugs, no weird behaviour so far. For a 33W unit, it’s not a power hog either. Running it several hours a day isn’t going to blow up your electricity bill, especially if you mostly use low/auto.

Out of the box, the Evalit ET066 is basically one main unit, the filter already installed, a short manual, and that’s it. No remote, no app, no fancy extras. The controls are all on the top panel with touch buttons: power, fan speed, auto mode, sleep mode, timer, child lock, and a separate pet mode. There’s also a little section for aromatherapy where you can add a few drops of essential oil, but it’s quite small, so don’t expect it to perfume a whole house.

The front has the PM2.5 display that shows a number and usually a coloured indicator (green/orange/red depending on the air quality). In practice, I noticed the reading goes up when I’m cooking or spraying deodorant and then gradually drops as the unit runs, so it’s not just a fake light show. The unit defaults to auto mode on startup, which is actually handy: you turn it on and it decides the speed based on what the sensor picks up. For someone who doesn’t want to keep fiddling with settings, that’s pretty convenient.

They claim a 2200 ft² coverage, which is honestly marketing talk for “it can move a fair amount of air if you give it enough time.” In a realistic setting, I’d say it’s comfortable for:

• Large bedrooms
• Living rooms up to 300–500 ft²
• Open-plan spaces if you run it almost constantly

On the feature list, the key points are: HEPA + activated carbon + washable pre-filter, timer up to 12 hours, child lock, pet mode, and sleep mode. No Wi‑Fi, no app control, no voice assistant. If you want smart home integration, this isn’t it. If you just want a plug‑in‑and‑forget device with enough modes to cover most situations, it gets the basics right without going overboard.

This is the part that matters. In daily use, the Evalit ET066 does what you expect a proper HEPA purifier to do: less dust, fewer smells, and easier breathing if you’re sensitive. It uses a three-stage system: a washable pre-filter, a HEPA filter rated for particles down to 0.3 microns, and an activated carbon layer for odours. I don’t have lab instruments, but I do have a dusty dog, hay fever, and an old flat that likes to collect smells, so it got a decent real-world test.

After a few days of running it several hours a day in the living room, I noticed:

• Less visible dust on surfaces and floating in sunlight
• Dog smell and cooking odours faded faster, especially on medium/high
• My nose was less blocked in the evenings during a high pollen week

The PM2.5 sensor seems fairly responsive. If I start cooking or spray deodorant in the same room, the reading goes up and the unit in auto mode ramps the fan speed up by itself. Once the air clears, it drops back to a quieter speed. It’s not instant, but over 5–10 minutes you see it react. That’s good enough for normal home use. For smoke, it also does a decent job: I don’t smoke, but I tried lighting a candle and blowing it out close to the unit, and it immediately picked up the spike and sped up.

Overall, in terms of pure effectiveness, I’d say it’s good value for money. It’s not magic; you still need to vacuum and dust, and it won’t fix damp or mould problems. But for pollen, pet dander, general dust, and everyday smells, it clearly improves the air. Compared to cheaper small purifiers I’ve used, this one moves more air and the difference in room freshness is noticeable, especially in spaces over 200 ft².
