A no-frills solution to pollution, a Smart Air purifier is a fan with a filter attached to it using a Velcro strap – the brainchild of Thomas Talhelm as an affordable way to clean the air in your home. The team at Smart Air send you the pieces and you strap them together.
There are currently two purifiers to choose from, the Original DIY for rooms up to 15sqm and the larger DIY Cannon for rooms ‘at least’ 30.5sqm – both of which are said to hold their own against their fancier and pricier counterparts.
Filters Smart Air purifiers use Hepa filters and, according to test results published on the Smart Air website, the Original DIY clears out 92 percent of PM2.5 particles over three hours, while the Cannon DIY clears 89 percent of PM2.5 particles in a 30.5sqm room – or 96 percent of PM2.5 particles in a smaller area.
Filters should be replaced every 140 days on the original model, with recommendations for more regular changes on the Cannon, as it filters air at a faster rate.
Settings Three fan speeds.
Extras Pre-filters are available for both models, and activated carbon filters are available for the DIY Cannon.
200RMB for the Original DIY; 470RMB for the Cannon DIY; replacement Hepa filters 80RMB. Available at smartairfilters.com
As well as selling some of the best value smartphones on the market, Chinese tech firm Xiaomi has smashed its way into the clean-air market with its high-tech, high-design purifiers at competitive prices. The second-generation Xiaomi purifier, the Mi Air Purifier 2 seems to do the job without breaking the bank, despite no longer being the newest model on the market.
Filters The Mi 2 uses a cylindrical triple-filter system – with a pre-filter, a Hepa filter and an activated carbon filter – purportedly sucking up 99.7 percent of the nasty particles and the gasses in the air. According to Xiaomi’s tests, the air purifier can clean the air in a 21sqm room in ten minutes – and should still be effective clearing rooms up to 39sqm.
Settings Auto mode detects the air quality in the room and adjusts the speed; sleep mode only allows the purifier to run silently; a purge function for extra-polluted days filters the air faster.
Extras A ‘smart’ purifier, the Mi 2 can be controlled remotely through the Mi Smart House app (available for Android and Apple phones). The app allows you to adjust the machine settings, see the levels of pollution in your house at any time and will eventually learn to automatically adjust the purifier’s settings depending on your routine.
