Technology

Air purifiers are essential indoor gadgets, especially for allergic and asthmatic individuals. They clean up the air in a room by removing contaminants, thus improving its quality. They come in different varieties and are used in various applications, for example, the medical-grade air purifier used in the manufacturing of pharmaceuticals. Air purifiers are either large or small stand-alone units depending on their use and placement area. This article shows the different technologies used by air purifiers.

Technologies Employed by Air Purifiers

All kinds of air purifiers work differently to provide clean and good quality air. There are five technologies involved, and it’s important to know how each works to help you pick the best air purifier. They are;

1. HEPA Technology

High-Efficiency Particulate Air technology is one of the oldest ways used for air filtering. The HEPA filters trap almost every bacteria in the air that is 99.97 percent, to be exact. They filter any particle larger than 0.3 microns, meaning the naked eye cannot see some of them like viruses, bacteria, and chemicals. Molds are common in most houses, especially those with poor lighting and airflow, and the HEPA filters trap them to give a clean and conducive environment.

HEPA filters consist of fibers arranged randomly over a surface where the air goes through for cleansing. The fiber is made of fine material that stops big particles from going through while the tiny particles are trapped using impaction, interception, or diffusion processes. After two to four years, the filters need replacement, but it depends on the level of filtration and the indoor air situation. These air purifiers are safe as they don’t produce ozone; however, they contain levels of activated carbon material to absorb some chemicals and odors that the HEPA filters cant trap.

2. Ozone

Air purifiers applying this technology produce the Ozone gas in varying amounts depending on the brand. They don’t rid the air of dust and pollen particles; hence, their effectiveness is low compared to other technologies. Exposure to ozone gas is not recommended due to health-related issues such as asthma flare-ups.

3. Activated Carbon Technology

Activated carbon goes through processing to create a porous surface for particle absorption. The pores are highly absorbent and have a high chemical bonding ability, ideal for trapping pollutants like gases and chemicals. Activated carbon filters reduce the contamination levels by not releasing the particles back into the air once they are absorbed. On the flip side, their ability to remove allergen is low and only cleans the air around it.

4. UV Technology

The technology is used alongside a particulate filtration system to help trap airborne particles. UV air purifiers kill microorganisms by destroying genetic composition using the UV rays from the UV lamp. Despite the light, filters must be used as most viruses and bacteria are not filtered due to shading from particulates.

5. Negative Ion Technology

This technology works, but it’s less efficient than others. The negative ion air purifiers attract particles and drop them when they become heavy. Instead of eliminating them, they are attached to objects in the room like windows and doors and have a high chance of polluting the air once they become loose.

Conclusion

All the air purifying technologies work in different ways; however, some are better than others. The level of air cleaning is higher in some and has minimal adverse effects. You can choose the best air purifier based on the information given and what matches your needs.

The 3D printing manufacturing process has been around for a long time, but it has only recently gained popularity in the manufacturing industry. Also knows as additive manufacturing, 3D printing offers a lot of advantages to manufacturers. But, just as every other manufacturing process, 3D printing also has its drawbacks.

3D printing has been a revolutionary invention where a computer file turns into a tangible prototype and then a useable product. More and more industries are moving towards 3D printing as their primary manufacturing process, and for good reasons. However, they still need to deal with the disadvantages of 3D printing too.

This article enlists the advantages and disadvantages of 3D printing in a precise and comprehensive manner. The purpose of this article is to help readers with the selection process so they can decide which manufacturing process they should employ. One thing is quite clear, 3d printing is one of the better options if you want to help the environment.

Advantages Of 3D Printing:

The additive manufacturing process offers multiple advantages over the traditional subtractive or injective manufacturing process. The most notable advantages are in terms of design, speed, and waste management. Let’s take a closer look at more benefits of 3D printing.

1. Reduced Waste

When you compare 3D printing to other manufacturing processes like CNC, you can see how much raw material is saved by manufacturing with 3D printers. While using a subtractive process, raw material is further cut, carved, and shredded to make smaller pieces. On the other hand, while 3D printing, raw material is morphed into the exact shape with very low wastage. This helps the environment as well as reduces the cost of raw materials.

2. Speed

3D printing is much faster than any other manufacturing process because making prototypes with 3D printers takes very little time. Once the design is final, you can have a prototype in your hands within a few minutes. The faster the prototype is given the green light, the quicker the whole process starts and finishes. 

3. Overall Cost

3D printing has a much lower overall cost because the whole manufacturing happens inside a single automatic machine. It saves a lot of time and labor costs, and of course, we mentioned the reduction in cost due to limited raw material usage. So, if you are looking to save time and money, 3D printing is your best bet.

Disadvantages Of 3D Printing:

3D printing is the next big thing in the manufacturing industry, but it has its cons too. To make a better and well-informed decision, you have to know about the pros and cons of 3D printing. We already saw the pros, now let’s take a look at the cons.

1. Material Compatibility

The biggest disadvantage of 3D printing is that it only works with plastic and a few metals. Because 3D printing involves the use of high temperatures and not all metals respond well to high temperatures, it limits the options of the manufacturer.

2. Size Restriction

Another significant limitation of 3D printing is that 3D printers have small printing chambers, which limits the size of the part that you can make. If you need bigger parts, you will have to use multiple printers to make the various components of the part and then join them together, which increases the cost, reduces the speed, and defeats the whole purpose of using 3D printing.

3. Copy Cats

3D printers are getting cheaper every day, so there is a chance that someone will steal your design, manufacture the same product, and sell it under their own banner. Because material options are so limited, there won’t be a big difference between the quality too.

There are various advantages and disadvantages of 3D printing, but if done right, the advantages outweigh the disadvantages of 3D printing. So, if you can find the right manufacturer, 3D printing is a great manufacturing process.
