HEPA filters were originally developed in the 1940s and used in the Manhattan project to prevent the spread of radioactive pollutants in the air. After the 1950s, HEPA filters were later commercialized, and this term became a trademark and is known as a general term for describing any high-performance filter. Over the years, due to the requirements for improving air quality in various industries, such as the aerospace industry, pharmaceutical processing and healthcare, HEPA filters have been widely used in these industries to help eliminate airborne particles, such as dust, dandruff, mold and asbestos.
In order to be considered a true HEPA filter, the filter must be able to remove at least 99.97% of particles as small as 0.3 microns in size. Particles of this size are the most difficult to filter, and they are considered the most permeable particle sizes or MPPS. HEPA filters consist of a mat of randomly positioned fibers that target and capture small particles with one of the following three mechanisms:
1. eavesdropping - When the particles pass the flow line in the air flow within the same radius of the fiber and stick to it.
2 blockage - When large particles cannot avoid HEPA fibers and are forced to insert them into one, which also increases with decreasing fiber separation and higher air flow.
3 diffusion - When the reinforcement mechanism occurs as a result of collision with gas molecules by small particles that interfere with and retain through the HEPA fiber.
Therefore, due to the excellent filtering properties of HEPA filters, they are extremely effective for removing particles from the air and surfaces such as carpets and upholstery, and their use can help the air in which we breathe are much healthier. Since our internal environment contains allergens, chemicals, gas, dust mites, mold and other harmful microorganisms, the airways struggle daily and suffer from these harmful pollutants. Poor indoor air quality can also cause symptoms such as itchy eyes, headaches, digestive problems, fatigue, congestion, and many other chronic and acute illnesses. In fact, studies have shown that more than each of three adults, children or babies suffering from allergies, asthma or respiratory diseases, and asthma is currently one of the leading causes of upper respiratory tract diseases in children.
Today, most HEPA filters can be found in air purification systems and even vacuum cleaners. HEPA vacuum cleaners use HEPA filters as part of the filtration process, and they are extremely useful for people with asthma and allergies, since the HEPA environment is capable of trapping small particles that can cause asthma symptoms and allergies. In order for the HEPA filter in a vacuum cleaner to be effective when cleaning particles, the vacuum cleaner must be designed so that all the air that has been drawn into the machine passes through the filter, and none of the leaking air passes by. In addition, due to the density of the HEPA filter, the HEPA vacuum cleaner needs a more powerful motor to ensure sufficient cleaning power.
There are essentially two main styles of HEPA vacuum: canister and vertical. HEPA vacuum vacuums usually have smaller, stronger enclosures that can roll forward and follow you when you make a vacuum carpet, furniture, or floor. A long hose attached to a HEPA vacuum cleaner will help you clean hard to reach areas. HEPA vacuum cleaners also often have separable wastes, which are more powerful than those found in the vertical HEPA vacuum. When a cannon-powered electric shock on a can’s vacuum cleaner stops working, the device can still be used to clean other surfaces. In general, for homes with predominantly bare floors and sparse durable areas, vacuum tanks can help you move easily from one area to another without scratching the floor.
On the other hand, vertical HEPA vacuums consist of a single unit, which may or may not be supplied with a mounting hose to help clean hard-to-reach areas with special vacuum tools. Upright HEPA vacuum cleaner can seep dusty air back into your home, and since the bar bar for carpet is permanently attached to the body of the vacuum device, as soon as this important component is destroyed, the entire vacuum must be replaced. However, if your home is mostly carpeted, the traditional vertical HEPA vacuum may be the best choice, as its drum bar shakes the dirt and dust beneath the surface of your carpet better.
In terms of design differences, these are different styles of HEPA vacuum cleaners, the most common of which are plastic cases using a disposable dust bag made from plastic used to trap dust from your carpet and vacuum cleaner. Keep in mind that with these types of models, dusty air can still flow through the gaps in plastic gases and even pass through the exhaust pipes and back into your home environment.
When choosing a HEPA vacuum, be sure to pay attention to the power of the model, since this is determined by its suction force in inches of water rise and its air flow (in cfm). All that has 90 cu. Feet per minute or higher is considered a powerful model and effectively removes pollutants from your home. Also look at the position of the placement of the HEPA filter. HEPA filters in vacuum can be placed both before and after the engine, and in some studies have suggested that the filter after the engine can help catch any fine carbon dust that is created by a vacuum engine. Strong seals to prevent leakage are also extremely important in the vacuum that filters are after the engine.
However, regardless of whether you choose a canister or a vertical HEPA vacuum cleaner, be sure that it can help eliminate dust and dandruff from your home, as well as alleviate your symptoms caused by asthma.
