We decorate the most reliable practice is of course pollution control, the use of environmentally friendly decoration materials, high environmental rating furniture and soft furnishings; healthy indoor environment is inseparable from the control of indoor air quality; high-quality indoor air is inseparable from a good air purifier; in the face of a variety of air purifying plants how to choose?
People who are suitable for using air purifying plants
Air purifying plants are not necessary for everyone, if you are in an environment where the air quality is very good, then air purifiers are not necessary to get, and you may even consider it an IQ tax. These categories of people are recommended to have an air purifier if you have the following conditions:
- People who have pets at home or in their environment
Nowadays, many families like to keep cats and dogs, but keeping pets will have the following problems: hair, odor, dander and bacteria, which can not be avoided, it is recommended that this group of people to acquire an air purifier. Focus on picking an air purifier that has the function of removing allergens and the dual function of air purification and disinfection.
- New house renovation, old house renovation, purchased new furniture need to deodorization crowd
Formaldehyde is a continuous release process, up to 15 years long, there is no way to be able to remove formaldehyde at once, so in order to their own health, or recommend that we go equipped with an air purifier, the new house can be selected to focus on deodorization of the air purifying plants.
- People with frailty/sensitivity/rhinitis/asthma/respiratory illnesses
At home there are elderly children, pregnant women, weaker, rhinitis and asthma and respiratory diseases, these people have higher requirements for air quality, plus nowadays air pollution is also really serious, taking into account the growth and development of the children at home, the health of the elderly, it is recommended to equip an air purifier.
- Smoking in the home or environment
If you are in an environment where people smoke, then you can certainly inhale secondhand smoke, which contains tar, nicotine, suspended particles and other harmful substances and carcinogens. We all know the harm of smoking, but do not know that second-hand smoke is more harmful than smoke, long-term second-hand smoke is easy to induce respiratory diseases, and, often inhaled second-hand smoke, these harmful substances into the respiratory airway, stimulate the mucosa of the airway will induce respiratory diseases, such as bronchitis, pneumonia, lung cancer and so on. So it is better to have air purifying plants.
- High level of air pollution in the surroundings of the environment/high level of air pollution in the city where you live
As we all know, air pollution in some cities has become more and more serious in recent years, with PM2.5 and PM10 values soaring, especially in heavy industrial cities.
PM2.5, also known as fine particulate matter, refers to the ambient air in the aerodynamic equivalent diameter of particles less than or equal to 2.5 microns, respirable particulate matter is the primary pollutant causing pollution of the atmospheric environment in our city, the main role of the hazards of human health: carcinogenic, teratogenic, mutant. ‘So in these cities with serious air pollution or live in the factory next to the viaduct next to the crowd is also recommended to be equipped with the air purifying plants.
How to choose the right air purifying plants
According to the standards released by the new national standard, an effective air purifier must meet four standards, which is the so-called three high and one low (high CADR value + high CCM value + high energy-efficiency rating + low noise value) of the new national standard.
- CADR value
CADR is one of the most important parameters of the air purifying plants, which is simply the amount of air purified by the air purifier per hour for the environment in which it is located (indoor), which is divided into solid CADR and gaseous CADR (gaseous CADR is also known as formaldehyde CADR).
There are two categories of CADR values:
①Particle CADR value: purification ability for particles
② formaldehyde CADR value: for formaldehyde and other gaseous pollutants purification ability
CADR represents the clean air output rate, the higher the CADR value, the stronger the purification ability of the air purifier, the greater the amount of clean air, that is, the better the purification performance.
Focusing on the CADR value of formaldehyde, the relationship between purification area and CADR value is as follows:
Calculation formula: use of space = (0.07 ~ 0.12) x CADR value
Example: If the formaldehyde CADR value of an air sterilizer is 600m³/h, then the applicable area is 42㎡-72㎡.
- CCM value
CCM is important for air purifying plants, it indicates the clean air output rate, the higher the CCM value, the stronger the ability to continuously purify and the longer the filter life.
CCM is also divided into two categories, particulate matter and formaldehyde, particulate matter from low to high is divided into P1-P4 four major grades, the highest grade is P4.
Formaldehyde CCM value of gaseous pollutants from low to high is divided into four major grades F1-F4, the highest grade is F4.
The higher the CCM value, the higher the cumulative purification capacity of the filter, which simply means that the longer the life of the filter, the lower the cost of consumables.
- energy efficiency class
Energy efficiency level of the air purifying plants affects the power consumption of the purifier. The new national standard energy efficiency level is divided into 1, 2, 3 this 3 levels, 1 level of energy efficiency is the most environmentally friendly, energy saving, power consumption is less, belongs to the international advanced level, priority to enjoy the national environmental protection subsidies. 3 level of energy efficiency belongs to the average level of the market.
- noise level
The lower the noise value of this parameter, the better. According to the provisions of the new national standard, air purifying plants run at the highest level, the noise value can not exceed 70dB, so when you look at the noise value of this parameter pay attention to its noise value range, the lowest gear, if the control is below 40 on the line, generally 40 below the noise value is still relatively quiet, will not affect the sleep.
