Smart Air DIY 1.1

Built by Thomas Talhelm, the very first Smart Air DIY purifier consisted of a single HEPA filter strapped to a fan. In response to concerns about finding the right type of fan and a trustworthy HEPA, Smart Air was launched to ship fans and filters at an affordable price, and the Original made its appearance in the air purifier market.

Now, we’ve returned with the Smart Air DIY 1.1, which brings with it several upgrades to our original machine that increase performance, safety and usability.

Air purifiers are extremely simple – a purifier is a fan + a filter. When more air passes through the filter, more clean air can be delivered to the user, thus the purifier is more efficient.

A simple side guard in the DIY 1.1 helps to secure the HEPA filter more firmly to the fan. Getting clean air has never been easier!
