    No, you cannot. They filter differently and do different things.

    The function of the purification equipment in the dust-free workshop is mainly to remove the suspended particles (dust, pollen, etc.) in the air and kill the viruses and bacteria adsorbed on it; At the same time, adsorption and decomposition of toxic and harmful gases in the air to improve indoor air cleanliness and achieve indoor air purification, the following matters should be paid attention to when purchasing air purification equipment.

    1. Safety: It has passed the safety testing and certification of authoritative departments to ensure the safety of purification equipment.

    2. Applicability: Choose air purification equipment according to the type of pollutants to be purified, or directly choose a fresh air system that can achieve fresh air. 3. Service life:

    As the purification filter tank tends to be saturated, the adsorption capacity of the purifier will decrease, so consumers should choose the purification filter cartridge with regeneration function to prolong its life, and choose products that have been verified by authoritative quality and have quality assurance. 4. Purification efficiency: The room is large, and the air purification equipment with large air volume should be selected; For example, a 15-square-meter room should be purified with a unit purification air volume of 120 cubic meters per hour.

    5. Filter material: good filter material (such as high-efficiency air filter filter material) has the ability to adsorb pollutants above microns; If the indoor smoke and dust pollution is heavy, you can choose the purification equipment with better dust removal effect, and if the air is not circulating, you can choose the fresh air exhaust fresh air system.

    Hello dear, the principle of air filter air filter is as follows:1. The filtration principle of the air filter is to separate the liquid water and liquid oil droplets from the compressed air, filter out the dust and solid impurities in the air, but cannot remove the gaseous water and oil; 2.

    The removal technologies of dust-containing particles mainly include mechanical filtration, adsorption, electrostatic precipitation, negative ion and plasma method, electrostatic electret filtration, etc. 3.In general, mechanical filtration captures particles in three main ways:

    Direct interception, inertial collision, and Brownian diffusion mechanisms. It has a good collection effect on fine particles, but the wind resistance of potatoes is larger. For high purification efficiency, the filter element needs to be dense and changed regularly.

    Hope mine can help you; Once again, I wish you good health and a good mood! 

    <> "Avoiding Misunderstandings in the Use of Air Filters.

    With the increasingly serious environmental pollution in the country, the content of inhalable suspended particles in the air is getting higher and higher, if these suspended particles enter the cylinder of the automobile engine, a large number of colloidal substances and tiny wearable particles will affect the combustion adequacy of the automobile engine, and then enter the cylinder and piston in the engine, causing the wear of piston related parts, resulting in the decline of engine performance. The function of the automobile air filter is to form a filter barrier between the air entering the cylinder, completely block the suspended particles from the cylinder, and ensure sufficient air intake, so as to ensure that the power of the automobile engine will not be lost.

    However, many private car owners do not pay enough attention to the maintenance of air filters, and some misunderstandings inevitably occur when using car air filters.

    Myth 1: Don't pay attention to quality when buying an air filter.

    Although many car owners now choose 4S shops when replacing air filters, with an in-depth understanding of the car structure, it is very simple to replace the car filter by yourself, but whether it is replaced in a 4S shop or by yourself, it will involve the problem of buying a new air filter. However, many car owners do not have a very correct understanding of the role of air filters, and often choose the most cheap and poor quality air filters, the air filtration capacity of these poor quality air filters is general, especially for fine suspended particles, poor filtration capacity, and poor physical stability, and long-term use will inevitably lead to a decline in the performance of the car engine, and fuel consumption will rise sharply.

    Myth 2: Remove the air filter from time to time when using the car.

    Some private car owners think that the car air filter does not play a big role, and after a new car has been used for a period of time, the air filter has been completely blocked, so the air filter is simply removed and not replaced. The result of this may not affect the performance of the car engine in a short time, but in the long run, the wear and tear of the car engine is very serious. Data shows that without an air filter, the wear rate of the engine cylinder would be more than eight times higher than the first one, the piston wear rate would be more than three times, and the piston ring wear rate would be more than nine times.

    Myth 3: The maintenance of car air filters is not flexible enough.

    Most private car owners also know the importance of replacing the car air filter, but when replacing the car air filter, they are limited by the car maintenance operation instructions, and then replace the car filter after the number of miles provided by the guidance. However, the different degrees of urban pollution nowadays, the corresponding number of suspended particles is different, if the degree of pollution is heavier in the northern cities, then the replacement and maintenance of the car air filter can not be simply known in accordance with the instructions, at this time the car state has been obviously abnormal, so the maintenance cycle should be shortened, improve the quality of the car filter. This is the right way to maintain it.

This is the right way to maintain it.

    Finally, car filter experts said that car filter is one of the core components of the basic 4 filters of automobiles, when buying car air filters, we must choose high quality, and at the same time, we must carry out targeted maintenance according to the use environment of the car during use, so as to truly achieve the ultimate goal of strengthening the heart of the car.

    There are many types of air purifiers on the market, and the key is to look at the brand, and I always insist on getting what you want. Air purifiers that don't use filters are still very useful. The one I use at home is a Fujitsu air purifier that doesn't have a filter.

    In addition, formaldehyde, benzene and other harmful substances, odors, and TVOC are quite effective.

    The air purifier technologies currently on the market are: HEPA filter, negative ion technology, and electrostatic dust collection.

    HEPA filter is a more traditional filtration method, the advantage is that the effect is good just now, but the effect decreases greatly after using it for a period of time, and it will become a secondary source of pollution if it is not changed regularly. Generally, the filter screen is replaced once every 3 months, and it is inconvenient to replace the filter screen, and the cost is 15%-25% of the machine, and the follow-up maintenance is time-consuming and laborious.

    Negative ion technology and electrostatic dust collection technology do not require a filter. The technology of big brand merchants is very mature. It is also the development trend of the future.

    One. There is no need to replace the filter screen, using high-efficiency electrostatic integration technology to adsorb particulate matter, and when the adsorption is saturated, only need to clean the filter screen (electrical dust collection device), which can be reused, and the dust removal ability will never decrease.

    Two. Releasing trace amounts of ozone can kill bacteria, and trace amounts of ozone are also good for the human body.

    Three. It is easy and convenient to use and clean.

    Definitely not effective, now air purifiers are all about cleaning the air through the filter. The more layers of the filter, the better.

    It's best to buy some well-known brands, such as the better brands on the market now, Panasonic, Philips, Langkong, Samsung, Daikin, Blueair, etc.

    It is of little use, and an "air purifier" without a filter is equivalent to an electric fan.
