The Xiaomi Smart Air Purifier 4 Lite offers you peace of mind and all-day protection for those who suffer from rhinitis and allergies. The air purifier protects your respiratory health by keeping the air in your home clean and safe to breathe. It does this thanks to a three-in-one filtration system that can remove up to 99.97% of 0.3μm particles. In addition to your high-efficiency filter system, your purifier also releases negative ions to keep the air fresh, helping you stay refreshed after a hard day’s work.

Xiaomi combines two filter technologies to give you the best protection. Xiaomi’s high-efficiency filter media can remove 99.97% of airborne particles of 0.3 micrometres in size and traps dust, PM 2.5, pollen, pet dander, smoke and tiny particles. The activated carbon filter has a high absorption rate and effectively removes common harmful gases such as VOC from your home, as well as eliminating odours to keep your air fresh.

Compared to a conventional HEPA filter, Xiaomi’s high-efficiency filter allows the air purifier to generate less noise and consume less energy by allowing more airflow to pass through the filter all the while keeping the same cleaning efficiency. Xiaomi Smart Air Purifier 4 Lite has a particle CADR of up to 360m³/h, able to deliver 6000L of purified air per minute, and with 360° all-round air intake, purifying your entire room is effortless.

Smart control keeps your home fresh when you’re on the move. With support for smart control, ensure that you always return to a home filled with clean, fresh air. Use the Mi Home/Xiaomi Home app from your smartphone to enable purification when away from home. The purifier also works with Hey Google and Alexa for voice control.

It also features a one-touch auto mode making it even more effective for hands-free purification. Its sensitive high-precision laser sensors then monitor changes in air quality. Once it determines the air quality in real-time it then automatically adjusts the purification speeds for automatic purification.

Switch to Night Mode to turn off display luminance for no-glare, no-noise purification. Your purifier will keep air circulating, providing you with the perfect environment for some undisturbed shut-eye.

Easy-clean air ducts help clean your purifier from the inside out. Unscrew and remove the grille for easy access to the fan blades and air ducts. This makes for easy cleaning for the inside of your purifier to prevent secondary pollution.

The air purifier is ideal for those suffering from allergies, or who live in areas where there is a lot of pollen. They are also perfect for newborn babies or children who need to still develop their immune systems. Improve your way of life with the Xiaomi Smart Air Purifier 4 Lite.

The Best for Athletics
Color: Black/Gray
This is a sleek, light wristwatch that will not weigh you down with its bulk. Forget the gigantic profile of a "survivalist" wristwatch. This unisex model is svelte and slim, not adding much to the wake you generate while swimming, or the swing of your arms while running, or the wind as it passes around your wrists and hands while you are speeding by on your racing bike. This is only 34mm across, by 35mm tall, by 11.5mm thick. The wristband is 13mm at its median working width. Timex styling cannot be beat, and neither is the resin-rubber-like material. I don't know about you, but the price is something I take a good look at. I want a watch that is reasonably priced and high-quality. I don't want to spend $200 to $1000 on a watch and worrying about being careful with it. If it gets smashed, it's only $30 to $50, not a big loss, and the quality is way better than what they were making in the 1980's. These watches are made for athletics and the real world.

Great watch, flimsy band
Color: Gray/Lilac
I bought this watch to replace a similar model because the band broke. I see this is a recurrent problem in many other reviews. However, I liked the watch enough to buy it again anyway. I found the new model easy to set, being fairly intuitive. So far it keeps perfect time. I use this watch mainly as a travel watch, and loved the dual time zone function. I am pleased that the newer model now has the ability to set 3 times zones instead of 2, which is an added bonus. The only con I see at this point is the flimsy strap. Unfortunately, the strap on this model is even thinner than on the previous one, and I wonder how long it will last. Also I wonder about the battery length. I think these watches may have been sitting around a long time. The setting showed 2012. I am afraid much of the battery life of the original battery may have already been used up and the battery may need replacing early. Only time will tell. The watch fits my small wrist fine and it is a little more attractive than the old model. I give it 4 stars instead of 5 only because of the band problem.

Fine for a man (with skinny wrists)
Color: Black/Gray, Color: Black/Gray
I have an older mens ironman which has gotten a little beat up and needs replacing. The band is much longer than I need. The metal clasp sits off-center on the underside of my wrist, closer to the part of my wrist which curves around to the front. The too-long strap sometimes flops around and catches on things. I couldn't find a smaller-band mens version, so I tried this "womens" watch (picking the most manly-looking one, of course). I like it better. The band fits my wrist much better, with the metal band in the middle and no flop. I also like that the watch is lighter and the face and band are smaller and less bulky, so it is less noticeable when I'm wearing it (cycling weight weenies will appreciate this). The face is still large enough to be easily legible and contains all of the same great features as my mens ironman watch, plus the newer versions now have an hourly chime, nice! Other info: my wrist is ~17.5cm or ~7.0" around. On this watch, I use the 6th out of 9 slots on the band. On my mens ironman, I use the 3rd out of 9 slots. Weight: this one = 28g, mens = 39g. Pics show comparison of my prior mens ironman with this new "womens" ironman. Photo order is confusing (couldn't figure out how to change that). They are: (1) side-by-side, mens on left, (2) mens band (wider and clasp is off-center on my wrist, end of band hangs over the edge of my wrist -- too long for me -- catches on things), (3) womens band (less wide, clasp is more centered on my wrist and end does hang over edge of my wrist), (3) womens watch (smaller, and looks new), and (5) mens watch, looking a little beat up.

Watch holds up in saltwater!
Color: Black/Gray
I bought this watch to use for my trip to the Galapagos Islands. I read two reviews that the watch does not hold up in salt water. I went snorkeling in the ocean 6 times, about 45 minutes each time. The watch did not leak. I did take precautions by keeping the watch under my rash guard and lowering myself slowly into the water. I also rinsed off my watch each time I snorkeled. I also bought this watch for the multi time zone feature by saving the time on the west coast, east coast and Galapagos time since I cannot change the time on my Fitbit until I land in an airport. I did not use any other features of the watch because I generally use my phone or Fitbit for an alarm or timer. The only complaint I have is that Timex now discourages changing the battery by the consumer. I changed the battery myself on my old Ironman watch. The new Ironman watch is fitted with triangular head screws. So I will have to purchase screwdrivers with triangular heads when it comes time to change the battery.
