Smart Air Filters Private Limited Ladosarai, Delhi

The Laser Egg tells you instantly and accurately what is in the air you’re breathing, so that you know whether or not you efforts to keep your environment clean and healthy are working. The Laser Egg provides air quality readings in real-time; measurements are taken every 0.1 seconds and displayed on the LCD screen. Air quality can be displayed as PM2.5 concentration, AQI (US EPA & Chinese standards), and particle count. An embedded Lithium ion battery means that you can take the Laser Egg around with you, wherever you go. The battery lasts for approximately 8 hours on a full charge. Or you can leave it at home, plugged in and recording data, 247.

This pollution mask is an N95 respirator. N95 respirators are a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. This mask has been rated N95 by NIOSH. The ‘N95’ designation means that when subjected to careful testing, the respirator blocks at least 95% of very small (0.3 micron) test particles. If properly fitted, the filtration capabilities of N95 respirators exceed those of face masks.

The other day, someone on Quora asked whether ionizers actually purify the air. This is an important question because ionizer purifiers are all over the place. For example, I was at a friend’s apartment in the US, and I saw his tower fan had an ionizer button on it:It’s also important because several friends in China have sent me links to ionizer products like this:Amazing! A “miraculous air purifier” that removes PM 2.5 and formaldehyde in just 30 seconds. And all that for far cheaper than regular purifiers and even cheaper than building your own purifier.
