Best Room Humidifier for Baby – Reviews and Guide 2016 Reviews, Single/Baby Room HumidifiersNew system is more effective than standard air purifier; capable of removing particles almost 10 times smaller than the PM<2.5 standard; helps to remove smell associated with the haze. A team of researchers from the National University of Singapore’s (NUS) Faculty of Engineering has developed a cost-effective solution for the control of indoor air pollution, especially from the haze. Led by Associate Professor Jeff Obbard from the Department of Civil & Environmental Engineering, the team at NUS invented a filtration system that is designed for use with a domestic ventilation fan to remove particulate matter measuring less than 2.5 microns in diameter (PM2.5) from indoor air. The NUS system is also able to reduce levels of volatile organic compounds (VOCs) that are typically associated with the odour from haze pollution. The development of this system by NUS researchers is timely in light of the World Health Organization’s (WHO) recent news on the risks of PM2.5 inhalation, which has been linked to a range of cardiovascular and respiratory ailments, including cancer.

Indoor air quality is also affected by PM2.5 f that seeps into homes and offices from the haze, traffic fumes and industrial emissions. “This new system is designed to filter out particulates down to at least 0.3 microns in size - almost 10 times smaller than the PM2.5 WHO standard. “It is important for any system to cover every corner of the room” said Assoc Prof Obbard, “We reduce PM2.5 where it matters most – in the air that we breathe, not just at the filter itself.”Assoc Prof Obbard noted that he had been surprised to discover from his research that air conditioning units did not always provide adequate protection against PM2.5, and could even be a source of PM2.5 if not well maintained. “Our goal is to provide everyone in Singapore with affordable protection against PM2.5 exposure at a fraction of the price of a regular air purifier” said Assoc Prof Obbard, “We wouldn’t think of drinking a cloudy glass of water, and equally we should all breathe the cleanest air possible.”

Assoc Prof Obbard took the system to Pekanbaru in Riau Province in February this year when there were over 1,000 hotspots in Sumatra. does a air purifier help with dustHe conducted tests in a Pekanbaru school classroom where the PM2.5 level nine times over the ‘safe limit’, as defined by the WHO. air duct cleaning won't stop callingAiRazor was founded by Assoc Prof Obbard, Mr Andrew Yap, and Mr K.

In case you didn’t know, Xiaomi sells more than just smartphones and related gear. Their product line includes home appliances, such as rice cookers. They also already have two generations of air purifiers. 

I recently bought the newer Mi Air Purifier 2, considering how it might be useful in our annual haze season, and thought I’d share a quick review on it. The Mi Air Purifier 2 has quite a nice sleek design. It’s not slender as some other air purifiers aim to be, but it has this functional, industrial, look that is both simple and beautiful. It’s squarish cross-sectional area of 240 x 240 mm is smaller than a sheet of A4 paper. It stands 520 mm high, and weighs 4.8 kg including the air filter. The design draws air from all sides of the unit, through a large circular air filter, then pushes it out upwards from the top. The plastic case looks a bit like metal from a distance, although you can easily tell it’s not when you look at it up close. The Mi Air Purifier 2 can easily fit into a corner of your living or working space without being an eyesore. Compared with its first generation brethren, the Mi Air Purifier 2 is shorter, and up to 40% smaller in volume. However, the smaller package is still quite powerful, delivering 330 m3/h Clean Air Delivery Rate (CADR) in standard mode, which is 81% of the first generation’s 406 m3/h CADR.

In active mode, the Mi Air Purifier 2 can do 388 m3/h CADR. Xiaomi says it can effectively clean the air in a 23 m2 room in just 10 minutes. That large circular filter is 200 mm in diameter and 293 mm high. It comprises a PET primary filter, HEPA filter, and activated carbon adsorption filter. It removes large particles, 99.99% of 2.5 micron particles, 99.3% of 0.3 micron particles, and 91% of formaldehyde and other harmful substances. It’s sounds like it’ll deal with our annual haze situation quite well. Operating the Mi Air Purifier 2 is really simple. There’s essentially just one button to turn on and off the device, and to select the  motor speed. Auto mode selects a speed based on the air quality. It can do that because the Mi Air Purifier 2 has a built-in PM2.5 air quality sensor. Night mode runs the fan ultra quietly, perfect for the bedroom when you’re sleeping. There’s practically no noise in this mode. The last mode, the favourite mode, fixes the fan speed at maximum by default.

The speed can be configured through the Mi Smart Home app. This brings us to a really big thing about the Mi Air Purifier 2. It’s a smart device. It has built-in Wi-Fi. It’s only 2.4 GHz though, no 5 GHz support. Using the Mi Smart Home app, available on both Android and iOS, you can remotely control the Mi Air Purifier 2, including turning it on and off, and controlling the fan mode, and adjusting the speed of the favourite setting. The app also lets you read the PM2.5 air quality sensor data, so you can tell how clean the air in your room is. There’s also temperature and humidity sensors in the Mi Air Purifier 2 that you can read from the app. If you want to check your filter status, the app tells you that too. The smart part of the Mi Air Purifier 2 might be quite interesting. But the air purifier itself is otherwise mostly quite basic. There’s no ionisation function, no UV light, and interestingly, not even a timer to automatically shutoff the air purifier. Perhaps the timer capability can be built into the app at some later time.
