Preface

Thank Lei Feng for giving this trial experience!

Nowadays, the problem of air quality has attracted more and more attention, and related products are emerging in endlessly.

The 720 Environment Treasure Plus focuses on air detection instruments that can be carried around and can detect the surrounding environment at any time.

What's unique about this device? Let me take my time.

Hardware Analysis

The reason why hardware is mentioned is to analyze the hardware cost of the product.

Formaldehyde of the product is tested by electrochemical method, while PM2.5 is tested by physical method such as laser detector.

In addition to temperature, humidity and noise, the cost of these sensors alone has reached hundreds of yuan,

Therefore, it can be found that the price of 720 Environment Treasure Plus is quite conscientious.

Software

A two-dimensional code is provided on the instruction manual in the package. You can download the application by scanning the code. It is suggested that you can directly give the name of the application in the App Store, so that users can download it from Apple's official App Store better:

Pairing required for first use:

You need to register an account before you can bind the device for testing:

There are advertisements for water purifiers in the app, but I feel that the 3M ultrafiltration scheme is not as thorough as reverse osmosis, hehe.

Test

Start the actual test. Here, the author introduces a newly launched air purifier with PM2.5 and formaldehyde detection functions to make a comparative evaluation with 720 Environment Treasure Plus.

First place the equipment at the air outlet of the purifier:

It can be found that except for the excessive noise, other values are all good:

The details are as follows:

Then place the test point at the air inlet. After comparing the values of the two, it is worth noting that there is a slight difference between the test values of the 720 Enviro Plus and the sensor of the air purifier, as shown in the following figure:

On this point, although the difference between the values is not large. I specifically consulted the customer service of 720 Environment Treasure:

Obviously, the value of 720 Environment Treasure Plus is relatively reliable.

Application Scenario

The author tried to put 720 Environment Treasure Plus at the air outlet of another air purifier. This air purifier has no PM2.5 and formaldehyde detection function. At this time, the 720 Environment Treasure Plus value is very meaningful and can be used to help judge whether the filter screen should be replaced:

The PM2.5 of the air outlet is still 0, indicating that the filter screen is still relatively new and does not need to be replaced:

Summary

720 Environment Treasure Plus can be said to be a small sparrow with all the internal organs. Its functions cover PM2.5, temperature and humidity, noise and formaldehyde concentration. It is enough for daily use. Moreover, the product design is small and portable. Compared with the first generation product, the removal of TVOC function is a small regret. Compared with the products on the market, except for the carbon dioxide concentration monitoring function, the function has been very perfect. And the equipment with carbon dioxide concentration test costs nearly 1000 yuan, and does not have formaldehyde test function.

Formaldehyde, PM2.5 and noise are three major functions that can be said to firmly grasp the pain points of users. Whether your home has just been renovated, or moved into a new house, or even used to detect whether the filter screen of the air purifier should be replaced, 720 Environment Treasure Plus is a magic tool that can help you draw conclusions at this time.

In fact, 720 Environment Treasure Plus is like a ruler, which can measure the length of objects, while 720 Environment Treasure Plus measures the air quality. With ruler, work and life can become more convenient. And with 720 Environment Treasure Plus can tell you how the air environment around you is anytime and anywhere. In this sense, I think 720 Environment Treasure Plus should be used by thousands of households just like the thermometer that every family has.

I have interacted with Mr. Xiang Ligang, the founder of this product, on Weibo before, and I am very optimistic about the prospect of similar products. It is hoped that this product can enter thousands of households and be recognized by more and more users.
