Levoit Core 200S - Smart WiFi HEPA 35 sqm

From the manufacturer Review: A fantastic air purifier for the price. Wish i had purchased it sooner. - This product has been excellent so far. It runs quietly on the lower modes and has a white noise (which i like) if you crank it up. It feels well-built, and does exactly what it’s supposed to. Air in the room is fresher and sleep quality has also improved. I noticed a difference in air quality within the first day of using it. The design is clean and modern, so it fits in with my room without standing out. Easy to set up and simple to maintain. The night light is a cool feature to have and the vesync app is easy to use and responsive. It allows you to control the various parameters of the machine remotely. Also purchased a blueair 511i max to compare alongside this and it outperformed it superbly. Particle filtration is fantastic. Now see less dust on surfaces. Does seem to help with odours too. Definitely worth the purchase and I’d recommend it to anyone looking for a reliable air purifier. Will purchase the larger one when it next goes on offer for our living room. Review: Seems pretty good (update added) - I bought this for my bedroom/office as it was getting more use working from home and I noticed an increase in dust and therefore allergies as I have the windows open to keep some fresh air and cool in the summer. 2 days in and I can feel/see the difference - Less sneezing and ichy eyes, no dust particles floating in the air when the shines through the window. Pros: 4 speed settings (High really does move some air, and night is very quiet). It works well in a 16' x 10' x 8' room. In the first 2 days of use I have removed the filter and cleaned off a layer of collected dust from the first mesh layer. Easy to remove filter (twist the bottom of the unit). Smart control via third party app and Alexa voice control (was super easy to pair and set up). Which works even if im out/away and not connected to the same network (unlike some smart devices). Programmable multiple step schedule in the app (on/off/speed/light/display) with loads of flexibility in the settings. Good length of mains cable (approx 1.5m) allows some flexibility in placement (see comment about placement). Night mode is pretty quiet (not silent but not obtrusive). Built in timer (also has a time in app functions). Built in night light (I don't use it). Recalls previous settings (so don't have to keep turning the display or night light off every time I change the fan speed). Remaining filter life in app plus easy reorder via app (or desertcart). Plenty of these sold so filters should be easy to source for quite a few years yet (either from the manufacturer or after-market versions). Cons: Slightly larger than I expected (I should have read the spec). But at least it's not massive. Rather annoyed it went onto a deal £15 cheaper the day after I bought it!!! (Technically not really a con, but still annoying). Replacement filters are £20 (although they will last 8-12 months if cleaned regularly and depending upon use). Useful tips: Don't forget to take the filter out if the plastic bag before turning it on (as some people have missed this)! Wipe or hoover the filter to maintain airflow. Google about best placement before buying to ensure you can place this where it will work best for you. I was surprised to read that floor placement is NOT recommend for best performance. I turned this on full power and dusted. It sucked up a lot of the visible airborne dust while doing this. Note on the video: This is on high setting, using a torch to show the dust being pulled in (I think I need to dust more often - or should have bought one of these years ago)! Summary: So good I've bought another one (for £15 less) for the living room. There are plenty of other brands and models to choose from, which I cannot comment on, but this is well worth the money. If you don't want/need to convince of smart features save yourself a few quid and get the standard model (still has a timer function, etc). UPDATE: As I mentioned I'm now running 2 of these, and the second one is quieter than the first. The main noise is airflow (certainly on the high setting), but there is also a slight squeak/squealing noise that has become more obvious now I have something to compare it to (the second one is near-silent in hight mode). So have requested a refund, and wil still buy another (especially if it's still on a deal price. Let's see how well the requested return goes. Perhaps there will be another update to add.
