Material selection of car Cabin Filter
Summer is coming, what material should I choose for Cabin Filter?
Unknowingly, it has entered summer, the temperature has gradually risen, and the frequency of use of car air conditioners has gradually increased. When it comes to car air conditioning, Cabin Filter must be the key.
The most important thing that determines the filtering effect of the Cabin Filter is the material. The Cabin Filters currently on the market can generally be divided into six categories according to the material: pure non-woven fabrics, bamboo fibers, cold catalysts, activated carbon, nano mineral crystals, and Hymanpu.
Many friends have difficulty choosing when they change the Cabin Filter: With so many materials, which Cabin Filter is suitable? Next, the editor will give you a detailed explanation
01Pure non-woven fabric
Non-woven fabric is very common in life. When it is processed into a Cabin Filter, it can only filter some large particles such as dust and sand. It cannot filter out odors, droplets, toxic and harmful gases, PM2.5, etc. Basically, it has been eliminated by mainstream manufacturers and belongs to the lowest-end products currently on the market.
Advantage:
1. Large air permeability;
2. The price is cheap.
Disadvantages:
1. Single-layer filtration can only filter large particles above 5μm;
2. Unable to filter peculiar smell, droplets, toxic and harmful gases, PM2.5, etc., and poor protection.
02Bamboo Fiber
Cabin Filter made of bamboo fiber is actually the same as non-woven fabrics, and the filtering effect is not even as good as some special non-woven fabrics. However, because bamboo fiber is a natural material, many businesses have appeared on the market with so-called "pure natural", "ecological filter" and other gimmicks to gain attention, but in terms of its own use effect, it is not recommended to use it.
Advantage:
1. Large air permeability;
2. It has a certain filtering effect on peculiar smell.
Disadvantages:
1. It can only filter large particles above 5μm such as dust and sand;
2. Unable to filter droplets, toxic and harmful gases, PM2.5;
3. The price is relatively high.
03Cold catalyst
Cold catalyst is a new type of air purification material. Under certain environmental conditions, it can react formaldehyde, toluene and other toxic and hazardous substances (TVOC) in the air with oxygen in the air to complete the purification. It is usually also available on the market. Known as the "formaldehyde buster".
In the production and application of Cabin Filter, the cold catalyst is usually matched with HEPA (HEPA-High Efficiency Particulate Air, the abbreviation of high efficiency filter, as long as the micron-level particulate matter can become a HEPA filter element) filter paper as the filter layer. However, in order to ensure the air permeability, the density of the filter paper usually used is not high, which causes it to basically have no filtering effect on PM2.5.
Advantage:
1. Effectively remove peculiar smell;
2. Effectively remove toxic and harmful gases such as formaldehyde and toluene.
Disadvantages:
1. Small air permeability;
2. The price is relatively high;
3. Basically no filtering effect on PM2.5.
04Activated carbon
Activated carbon Cabin Filter is currently the most common air conditioning filter element on the market. It integrates filtration, adsorption, interception, and catalysis. It has a good filtering effect on car odors, toxic gases, and PM2.5. Some products are also It has the effect of bacteriostasis and sterilization.
At this stage, most of the car Cabin Filters use ordinary activated carbon + HEPA filter paper as the filter layer, and some manufacturers use coconut shell activated carbon as the filter layer, which has stronger adsorption performance and better filtration effect, such as our super clean activated carbon series and Ultimate series air-conditioning filters Cleaner.
Advantage:
1. Effectively filter PM2.5 (need to achieve a filter grade of H11 or higher);
2. Effectively remove peculiar smell and toxic and harmful gases.
Disadvantages:
1. The price is relatively high;
2. The air permeability is relatively low;
3. For ordinary car owners, it is difficult to distinguish between ordinary activated carbon and coconut shell activated carbon.
The method of distinguishing the filtration grade of HEPA filter paper is more complicated, so sometimes it is easy to be misled. It is recommended that car owners choose well-known first-line brands when buying.
05Nano mineral crystal
Nano mineral crystal is an air purification material that has only emerged in recent years. It is characterized by desorption (ie the reverse process of adsorption) at a temperature of 45°C and above, making the material reusable and theoretically greatly extending the service life of the product ; At the same time, its internal pores are several times that of activated carbon, and are nano-scale, which has a miraculous effect on adsorbing nano-scale harmful gas molecules.
Some manufacturers use the combination of nano mineral crystal + HEPA filter paper to make nano mineral crystal Cabin Filter. However, due to the influence of the shape and the medium itself, the air output of the product is too small. At the same time, it is limited by its high cost, which is doomed to nanometer Cabin Filter is very rare and difficult to popularize.
Advantage:
1. Long service life;
2. Effectively filter PM2.5 (requires filter material to filter grade above H11);
3. Effectively remove peculiar smell and toxic and harmful gases.
Disadvantages:
1. High price and low cost performance;
2. Small air permeability;
3. It is not easy to install.
06 Hymanpu
Hymanpu can be regarded as a kind of composite ceramic particles, similar in shape to nano mineral crystals, and its filtering principle is to carry out oxidation and catalytic reaction with harmful gases in the air to achieve the purpose of purification. Hymanpu can effectively filter PM2.5 when it is matched with a filter material with a filter grade of ≥H11. However, due to the high cost, it is usually used in household air purifiers, and it is relatively rare in Cabin Filters.
Advantage:
1. Effectively filter PM2.5 (need to achieve a filter grade of H11 or higher);
2. Effectively remove peculiar smell and toxic and harmful gases.
Disadvantages:
1. High price and low cost performance;
2. It is not easy to install.
Summer is the time when the car air conditioner is used the most frequently. Changing a suitable Cabin Filter for your car in time is also an effective way to protect yourself and your family's breathing health in the car.
